This week, I completed the following tasks in the character blueprint:
Set up footstep sounds
Added mouse input for aiming down sights
Created a transition to zoom the head during aiming
Adjusted walking speed while aiming
Added depth of field effect when aiming
Set footstep sounds specifically for aiming movement
Created the weapon blueprint
Wrote a custom event for weapon firing
Added a weapon state machine
Added weapon sound effects, bullet effects, and reload effects
Implemented bullet hit effects
Created a function to count bullets
Built the reload blueprint
Added natural bullet spread
Added recoil effect when firing
Added bullet glow effects
This week, my main focus was still on blueprint scripting. Once the character and enemy blueprints are done, I can just drag them into the map and use them directly. Although there are many follow-up steps afterward, the blueprints are definitely the top priority.
After finishing them, I’ll move on to reworking some model textures, building the scenes, creating the UI and main menu, and finally packaging the game.
Last week’s recording wasn’t very clear, and Windows Game Bar can’t capture multiple windows well.
Especially when I opened the blueprint editor, it kept recording the main window—pretty awkward!
This week, I found a recording software called OBS Studio, and I’ve discovered it works really well.
Set up footstep sounds:
I selected the audio files and created a single cue. Then, I added an audio modulator to unify the pitch and volume across these sounds, while also introducing random variations in pitch and volume. This way, when played back, the audio feels much more dynamic and natural：
Then, I went back to the animation asset and added a “Notify” — “Play Sound” — selecting the sound cue I just created.
Added mouse input for aiming down sights
Similar to before, I added mouse input, set it up as IA_focus (for aiming function), and linked it inside the character blueprint. This lets me control the focus with the mouse smoothly.
I used a timer to make the aiming zoom effect transition more smoothly. This approach will also come in handy later for toggling the flashlight and handling other action transitions.
Adjusted walking speed while aiming：
In the speed calculation function, I added a condition that if the character is aiming, the selected float value becomes 150(150 for the speed of walk with aiming).
Then I add blueprints for the weapon, cause there are some functions like reload ammo and ammo calculation, I need to split these from character blueprint, otherwise, it will be mass.
Then, in the weapon blueprint, attach (or spawn) the weapon to the character’s arm.
In the weapon blueprint, I set up the following event icons: fire_weapon, change bullets, and recoil.
In fire_weapon, I configured three states: start firing, firing, and stop firing. Then I used play animation montage to connect the animation assets to each of these states.
The rest of the operations are all shown in my screen recording：
This week, I mainly worked on setting up the character blueprint, including:
Character capsule setup and camera setup
Character state machine setup (idle, walk, run)
Implemented camera rotation control using mouse movement
Added shift key input to trigger the running state and linked it to the state machine, enabling communication between the character blueprint and the animation blueprint
Added weapon drag effect (weapon swings slightly caused by camera movement)
Added character detail lighting (I wanted to create a warm light to simulate a body-attached light source, combined with a cold light for contrast)
Effect testing
Before getting started, I will provide all the assets I used and the link to the tutorial I followed. Since the tutorial I found is from the Chinese platform Bilibili, I won’t be able to share a YouTube link for the video resource.

5. Tutorial：
The course is taught by the creator of the game “Deathly Stillness”, which is available on Steam. Through the course, I learned how to create character and enemy blueprints, The character and zombie asset packs (including skeletal meshes, animation assets, and audio assets) were provided as part of the course and used for practice.
At the beginning, I set up the Animation Blueprint, Character Blueprint, and Blend Space for the character.
When I started setting up my character, the first step was to create a Character Blueprint. Inside the blueprint, I added the character mesh and carefully adjusted its position so it sat correctly within the capsule collider. This ensures that the character’s mesh and collision boundaries are properly aligned, which is really important for smooth movement and interaction.
I applied the same process for setting up the camera. I attached the camera to the character blueprint and positioned it in a way that works well with the gameplay perspective I want to achieve.
These might seem like basic steps, but getting them right early on saves a lot of trouble later in the pipeline—especially when starting to work with the animation blueprint and player controls.
Since the screenshots were taken later in the process, they include some updates like the arm texture and a few event icon features I added along the way.
Character state machine setup (idle, walk, run)：
Inside the Animation Blueprint, I set up the State Machine, including Idle, Walk, and Run states.
Idle
Move
In the Blend Space, I blended the Idle, Walk, and Run animations, and set up the corresponding movement speeds.
For example, I set the walking speed to 300 and running speed to 750. Since my scene is quite large, I needed the character to move a bit faster to fit the scene.
Implemented camera rotation control using mouse movement：
I also changed the bool input to Axis 2D, since the mouse controls the camera rotation based on X and Y movement on the screen plane. Using a bool would only allow simple on/off states, while Axis 2D lets me read continuous input values, which is more suitable for smooth camera control.
I used the Input Mapping Context to organize all the input settings and define the input devices, making the control setup more clean and modular.
I added a Look event in the event graph to call IA_look：
Added shift key input to trigger the running state and linked it to the state machine, enabling communication between the character blueprint and the animation blueprint：
In IA_run, I used a bool because it’s a simple on/off check—whether the key is pressed or not.
Similarly, I set up the Shift key input within the Input Mapping Context.
I added an if-run boolean check in the running graph. Then, I created a speed calculation function that uses this boolean—if the character is running, it sets the speed to 750, otherwise to 300.
Added character detail lighting (I wanted to create a warm light to simulate a body-attached light source, combined with a cold light for contrast)：
This was my first attempt at adding a warm light attached to the character, so I added a point light inside the capsule.
Later during testing, I adjusted the light settings and created a toggleable flashlight-like feature for illumination.
IA_open_lightOpen light functionI added this feature in the later stage, so I recorded it using the current version of the project files.
In this shot, George suggested that I redistribute the timing of each action, so the overall animation follows a slow-in, fast-out, slow-in principle.
Currently, my timing is more like slow-slow-fast-slow. Before the character stretches her leg toward the body, I added a preparation pose to build up energy, but George suggested removing it because it feels a bit awkward.
He also recommended speeding up the actions after the character lands and as she stands up, as well as making the following step forward quicker.
So I made some adjustments, but I noticed there are still some issues. For example, when the character is preparing to jump, I had her hold the pose completely still for three frames, but this made the movement feel a bit stiff. If I try to add a slight movement during those three frames, it ends up looking twitchy because the hold is so short.
This week, I received feedback from George, made some changes to the key poses, and deepened my understanding of the animation.
It’s clear that the character’s foot poses need significant adjustments. As the end point of the limbs, the feet tend to have a slight delay at the beginning and during the movement — they don’t move exactly in sync with the legs or on the same level.
Moving Hold means that when a character is holding a pose, they shouldn’t be completely still — there needs to be some slight movement. Even something as subtle as breathing, a small head tilt, or a gentle body shift can make the character feel more alive. If a character stays perfectly frozen for a few frames, it immediately gives off a “mannequin” vibe, especially in 3D animation where complete stillness feels unnatural. Compared to 2D, where we can use line wiggles or stylized shaking to fake subtle movement, in 3D we really have to animate those micro-movements by hand.
My personal understanding is: don’t let your character die on screen. Even just a few frames of subtle “fake movement” can add tension and realism to the shot.
Copied Pairs
Copied Pairs are a specific technique used to create moving holds. The process is actually pretty straightforward — you take your key pose and duplicate it, then move the duplicated keys a few frames forward on the timeline. This creates a pair of identical keyframes that hold the pose for a bit.
At first it might seem like a lazy shortcut, but in practice, you can slightly adjust the in-between to add a soft transition — like the character shifting weight, breathing, or gently swaying. It creates a subtle sense of motion within a hold.
I see this as a way to refine your blocking — beyond just having key poses and breakdowns, you’re adding mini-transitions that give your animation more depth and rhythm.
This is my attempt to moving holds and copy pairs:
I added a pause to the pose where the character opens her arms — I felt like she was building up energy for the next sequence of movements, kind of like a gymnast preparing for a routine. Then I copied and pasted the keyframes and extended their duration. In the spline phase, I adjusted the curves to give her a slight sense of motion, so it feels like she’s subtly shifting, not completely still.
BREAKDOWNS & Arcs
During blocking, it’s important to pay attention to the movement of the hands, limbs, and the COG — making sure their motion follows arcs instead of straight lines.
George suggest to make the animation shorter as there are too many poses, and it last too long, so I make some changes of my plan. After the character stand up, she will move forward for one step and stop there:

Workflow checklist:
When I am animating, it’s easy to feel overwhelmed by the sheer number of steps between your initial idea and a polished final shot. This week, teacher introduce his workflow checklist to us, and it is really helpful.

New mindset: reviewing your animation with fresh eyes.
Non-performance texture
Fix tiny things like toe splays on blinks — like breath cycles, toe splay, or tiny eye movements. These often-forgotten details are what truly bring a character to life and separate good animation from great.
This week, teacher introduced some experimental opportunities we can explore this semester, so I’m thinking that I might take this chance to push myself and create an FPS shooting game.
Recently, the second season of The Last of Us has been airing, and I really love its art style. The decaying cities are covered by plants, and people embark on a survival journey.
What sets this work apart from other zombie-themed works is that it more realistically reflects a cruel and heartless world. For example, under the rampant spread of cordyceps fungus, the government not only fails to provide shelter to the people but instead takes those who are uninfected in surrounding towns under the pretext of sending them to safety zones, only to kill and cremate them in the wilderness. The reason is that the higher-ups believe that if these people die, they won’t be infected in the future, which would reduce their workload.
After the outbreak, other survivors desperately scavenge for resources in order to live. Some even use lies to lure others in, only to kill them and steal their supplies when they least expect it. In that world, humans seem to have become even more terrifying than the zombies.
Inspired by this, I want to make a zombie FPS game. However, I need to think about how to make it and what the protagonist’s purpose in the game would be.
So, I’ve been researching the art design of The Last of Us to get some inspiration：
We can see that most of the city scenes are open and spacious, while enclosed areas usually feature a focal point that draws the player’s attention, along with strong lighting contrasts to guide them in the right direction. Since I’ve never tried designing game levels before, I don’t really have a clear idea of where to start.
I’ve built a game level in Unreal Engine where the player can move back and forth. The layout is shaped like a “U”. The player spawns underneath a collapsed overpass and needs to find the correct path by navigating through the wreckage and abandoned cars. Along the way, zombies will appear to challenge the player.
In terms of gameplay expectations, the player can see their destination—an area filled with tall buildings—in the distance from the overpass. This visual cue encourages the player to explore and figure out how to reach that location. When the player discovers a way to climb the collapsed structure and get onto the overpass, they gain the opportunity to observe their surroundings from a higher vantage point.
The first area is designed like an isolated island, so the player needs to traverse vehicles and the overpass to reach the second section. I want the player to do more than just stand in one place shooting zombies—I want them to actively explore the city, using collapsed structures and debris to discover new paths and move from one location to the next.
The second area the player reach is partially submerged in water, so they have to move forward by stepping on sunken cars. If the player falls into the water, they will die.
I referenced this picture:
Then, while building the level, I imported Unreal Engine’s first-person shooter template to test it. Through testing, I discovered that there are some issues with the scene.
For example, the player needs a strong motivation to explore the map and receive positive feedback—but figuring out how to design that feedback loop is quite challenging.
The second issue is that the scene is too open and expansive, which results in endless skylines in the distance. If I were to build out all the surrounding buildings, it would require a massive amount of work.
A massive map would make the entire gameplay flow more complex. So I think I need to find an alternative approach, even though I’m quite reluctant to let go of this level.
Find Plan 2:
How can a zombie shooting game remain engaging when the scene is smaller in scale? How can I make the decaying environment more interesting?
I was reminded of Escape Room, where the protagonist is tricked by a company—thinking they were just joining a regular escape room game, only to realize that failure means death. So I started wondering if I could incorporate something similar into my game.
For example, the protagonist could also be participating in what they believe is a live-action immersive experience, but it turns out they’ve been deceived and thrown into a zombie-filled environment. They must outsmart the zombies and gather materials to repair the safehouse door lock in order to escape. Meanwhile, everything is being livestreamed by the company for profit. When the protagonist defeats a zombie, viewer reactions and comments would pop up in the bottom left corner of the screen, showing the audience’s responses in real time.
However, although this idea is quite diverse, it would be difficult to implement. For example, how to write the blueprint for delivering items（like find, pick tool to fix the safe door), and how to design a real-time feedback system in the bottom left corner similar to a live stream. I searched online for tutorials but couldn’t find much to reference, so I need alternative solutions.
Find Plan 3:
I thought I could continue my game design based on some tasks I completed last semester. In our group project last semester, we designed a dungeon short film, but due to some factors, the entire scene turned out quite dark, and my model didn’t look great in the scene. So, I thought I could design my own dungeon game, using the gargoyle as one of the enemies.
I tried using Mixamo’s animation library and motion mapping to implement actions like attack, chase, idle, knockdown, and hit reactions. However, I still need to adjust the animation blending and manually keyframe the wing animations：
This way, I can apply the model assets I previously created to design a game, which I think will be quite meaningful.
So, I plan to create a first-person, single-player game set in a dungeon. The protagonist is a member of a mysterious organization, sent to investigate supernatural occurrences and deal with the roaming monsters. The story’s opening is somewhat similar to the beginning of Resident Evil, where the protagonist goes to a strange village or eerie mansion to investigate and ends up killing the leader inside.
Although the game might not have deep spiritual themes or messages, I want to learn how to write blueprints and the process of creating game enemies, and I believe I will gain a lot from it.
Art style
In terms of art style, I suddenly thought of a game I played back in my primary school: Dark Meadow: The Pact，which was developed by Phosphor Games Studio based in Chicago, was built using the Unreal Engine 3 and was first released on the iOS platform (iPhone and iPad) on October 5, 2011.
The player wakes up in an abandoned hospital, having lost all memories of the past.
The only “guidance” comes from a man speaking through a loudspeaker. He claims he was once trapped here as well and tells you that the only way to escape this nightmare is to kill a being known as The Witch.
As the player battles monsters in the hallways, gains experience, and ascends to higher floors, the story unfolds—eventually revealing that The Witch is, in fact, the player’s own daughter.
Game Plan:
So, I wrote down all my game ideas to make sure I won’t forget them later. I’m planning to create two maps: the first one is a forest map on the surface, and the second is a dungeon map. I hope I’ll have enough time to finish both of them：
In my FMP, I plan to create a chase animation set in a cyberpunk city. The story takes place after Earth’s environment has been destroyed, and humanity is forced to live in limited-space, mobile cities. Due to frequent disasters, the cities move to different locations. To make transportation easier, the cities are designed in the shape of containers with buildings on the top and bottom to save space.
In a world with limited resources and a deteriorating environment on Earth, multinational corporations set their sights on interstellar immigration. With their propaganda, some wealthy individuals have already moved to other planets, but labor is needed to support the workforce and colonization efforts. The protagonist, an ordinary person, signed an unequal contract with the corporation, which secretly replaced her original body with a mechanical one. Now, her appearance is a projection based on preferences and DNA calculations, and her true body is fully robotic.
After an unexpected program glitch, she was cut off from the company’s monitoring system. She reached out to the colonized aliens and struck a deal: If she could infiltrate the company’s headquarters on Earth and steal a gene ball containing the DNA of original creatures, the aliens would rebuild her real body. Once she obtains the gene ball, she escapes the city, regains her body, and joins the aliens and other workers to fight back against the company’s exploitation.
However, my animation project will only focus on the segment where she escapes the city due to time limits.
In this shot, I tried to increase the viewer’s sense of immersion by having the character as close to the camera as Ekko is. She spins around in front of the camera and the fly machine is very close to the camera. But in fact, the character’s actions lacked logic, as if she was acting knowing the camera’s point of view.
Also because of the need to get to the camera for the flying machine, the character’s lower body had to be very close to the camera, which makes the scene a little awkward. And because it’s too close to the camera, a few frames get blocked. But the main problem is still that one of her spinning behaviours in front of the camera looks rather strange.
So George suggest me can shot in the begging when the character face to the camera, so she will not turn around, just follow the motion trail looks like below:
Also, there are speed issues. For example, when the police car and the character are about to collide, both sides slow down. George suggested that I could keep the police car from slowing down and make everything happen fast. I plan to adjust the speed this week.
So I adjust it like this:
When editing this shot, I found it difficult to replicate the 2D composition because the camera’s field of view is limited. The character needs to fold their body to fit both the aircraft and themselves into the shot at the same time.
I tried to make the character perform a spiral rotation. I adjusted some keyframes and curves, removing unnecessary keyframes so that the overall animation looks smoother than before.
Moreover, George suggested that I modify the design of the flying machine to be in the shape of a skateboard with some larger planes. That way the character’s lower body can come sideways without having to keep moving horizontally all the time. When the lower body is always facing forward but the upper body is turned sideways, the movement can be a little strange.
The third problem is that the character decelerates for a while after getting out of the way of the police car, and then doesn’t continue to fly in the same spiral direction as before. So I need to get to the bottom of this.
The difficulty with this problem is that the camera is moving at the same time to avoid the character being too small a proportion of the screen. However, when the character and the camera are moving at the same time, cranking out the proper motion trail in normal view doesn’t make the character’s position in the current camera correct. This is because both sides are making coordinate changes. I think I’ll spend some time on this part to make it look normal in camera view.
Also, the speed problem still exits. Before I followed the fast-slow-fast principle, which was simpler and rougher to deal with. After George wrote the notes for me, everything became intuitive. The changes in speed are not averaged over a whole shot, but are based on the character’s trajectory.
In this week, I change some of the order of the shots, and delete the close up shot for character’s eye. I feel the story looks more smooth and connect after I change it. Cause some of the shot gives audience anticipation to what the character will do and why she do this next. That makes the whole action more logic.
This shot I added in week 6, when George and I were discussing how to give the character a close-up, and he suggested that I could jump down an air duct, which corresponded to the episode where she was wanted by police.
I delete the shot of her eyes, and make the shot looks like the fly robot notice the police car is coming.
Then the shot is the police cars fly to her
In week 7, George suggest me she can put the ball into robot body, with the camera went down, so gives audience a signal they notice the police and prepare to escape.
As previous shot the fly robot flies down, so it create a connection of the change of the robot position.
In this week, I edit the movement of the character, Before that, I added a move where the character is about to get hit and spins around in front of the camera to avoid it, and George thought there was something weird about that, it looked like he was dancing, so I got rid of it. It did work a lot better after I removed it. I find that often I complicate simple problems and simplify complex ones.
In this week, George advice me can add a shot shows the door is almost close up, like as the first person perspective. That may make connection between this shot and next shot.
I also drew the character design for the protagonist and the concept art for the flying robot.
She is an ordinary person who has signed an unfair contract with a large corporation and is forced to participate in alien colonization. The company stripped her of her body and transformed her into a fully mechanical prosthetic to work in extreme conditions.
So her current appearance is actually a projection, which is why she has such a strong physique and can navigate through the city. This is because her real body is made of mechanical components.
After an unexpected program glitch, she was cut off from the company’s monitoring system. She reaches out to the colonized aliens and makes a deal with them: If she can infiltrate the company’s headquarters on Earth and steal the gene ball containing the genes of the original creatures, the aliens will rebuild her real body(Her appearance is a projection). After she get the ball, she regains physical body and along with the aliens and other laborers, fights against the company’s exploitation.
However, considering the workload, my animation will only include the segment where she escapes the city.
The little robot is a simple and cute character, with a screen on its face to switch expressions. However, considering the animation, the little robot might be redesigned into the shape of a skateboard.
