My name is Ivan Mitsov and I am a gameplay programmer, working mostly
in Unity, C#, Unreal Engine and C++.
An Unreal Engine multiplayer game made to simulate a casino in a virtual
world with social features. Developed at my internship at
Animajor - Sofia, Bulgaria.
My responsibilities:
• Game Logic - The logic of classic casino games to be
implemented into the game.
• Multiplayer - Every game had
to be with multiple seats and work in multiplayer while everything is
synchronized.
• API - A backend had to be used to keep
track of players' profiles and balance.
• UI - Implementing
all of the UI from Figma to Unreal.
• Motion Capture -
Setting up a mocap environment and suits and importing the animations
and retargeting them.
A prototype of a car simulation made in the Unity engine aiming to use real life values to create and configure cars to be used in games.
• Suspension - it keeps the car above the ground and responds to
unevenness in the terrain. It is highly customizable and will work for
any type of car, even monster trucks.
• Ackerman Steering -
I've implemented a technique for steering used in cars in real life in
which the front wheels rotate by a different angle to accommodate for
the difference between the distance to the turning circle center.
• Customizable engine - the engine script has a graph in
the inspector which allows me to input any engine properties and the
code will adapt accordingly. It uses real life values for all
calculations.
• Gears - Added manual gear switching which
also uses real values of the car's gearbox and it's gear ratios.
• Flexibility - The code is well adapted and importing new
cars involves dragging in a new model and adjusting it's numbers(engine,
weight, gearbox)
A VR seated horror experience in Unreal Engine.
• Scripting - I implemented tools to help artists easily add
sounds and effects at a specified time and a function to wait until the
player is looking towards the action before playing key animations.
• Graphics - I was in charge of post-processing to make sure I
set the correct mood and lighting while keeping in mind the performance.
A base project for future use which includes the most common features in platformer games.
• Custom acceleration and decceleration - Custom physics
calculations still using Unity's Physics System.
• Coyote Time
- Allows the player to jump shortly after leaving the platform.
• Jump Buffer
- If the player presses jump before landing it buffer it until the
player touches the ground.
• Jump Curves - Custom control
over the gravity at any point of the jump.

Produce Abuse is a small turn-based game inspired by Pokémon made with C++ and SFML. It's made with OOP in mind and characters' data is read from text files. It has a simple AI and high scores. Code structure is based on custom GameObject class I made, which is meant to be similar to Unity's, because that's what I'm most familiar with.
A prototype of a rouguelike made in 3 weeks in Unity by 6 people.
My contributions:
• Gameplay - I developed the movement to feel good and
responsive, including some vector calculations to take the isometric
perspective into account.
• Rolling - Using raycasts I made
it so you can roll through specific objects and testing if there's an
obstacle on the other side and prevented clipping into walls.
• Shaders
- All of the shaders - grass, bushes and see-through material.
• Random level sequence generation
• Saving/Loading.
• UI, Pause screen, other misc.
A prototype of a rouguelike made in 3 weeks in Unity by 6 people.
My contributions:
• Gameplay - I programmed boat controls for all types of
controllers, using exponential graphs for turning to make it more fun to
play.
• Fishing Minigame - Including probabilty sliders and
other designer tools.
• Menus - Sound options, tutorials,
main menu.
• Shaders - Water shader re-used from Shader
Personal Portfolio, but I cartoon-ified it.

I wanted to experiment with shaders and learn something new with each of them so I created a few to learn a new technique with each of them. I set up a Unity scene and decided to make a MOBA-type character controller, so I can have more freedom in the theme of things.
• Outline shader - By expanding the mesh I found I can achieve a
somewhat good outline effect.
• Shield shader -
Experimanting with UVs, time, transparency and emission I created a
shield effect.
• Grass shader - A shader which uses time to
displace the top o the grass blades to make it look like wind blows, and
using the player's position to move them apart when he's passing
through.
• Portal shader - Learning about Unity's depth
texture and distortion I made a swirling portal.
• Water shader
- Using gerstner waves I managed to make a somewhat realistic water
shader and combining the portal distorion in it.
My goal was to learn about procedural animation by making a ragdoll
which can play animations.
My inspirations were Gang Beasts and Human Fall Flat.
• Inverse Kinematics - Using a basic setup I am setting the IK
goal's position to where the raycast hits.
• Automatic Stepping
- After the leg's goal gets too far away from the body I move it to the
opposite side and lerp the position with a sine wave.
• Ragdoll
- The character is set up with a collision and RigidBody on each bone
and a configurable joint connecting them all.
The joint also has the spring force enabled to try to adjust the
rotation to the default pose.
• Copy Animation - By setting the target rotation of the
joints to be the same as those of an animated copy of the character, the
ragdoll should be copying the desired animations.
