Description:

Planet Light-Year is a 3D real-time tower defense game where the player can place towers to destroy the invading minions and control an avatar to turn the tide of battle.

Planet Light-Year is a game developed by a team of 4 programmers in 4 months.
It was built by custom ECS based 3D engine in C++/DirectX from scratch and also has a in-build editor.

Title:

Game Designer / Gameplay programmer

Role:

• Involved in implementing Entity-Component-System(ECS) architecture for the engine.

• Built the scripting engine and used python as scripting language.

• Built the physics engine with GJK for collision detection.

• Built octree for space partitioning.

• Built the map manager for storing path nodes for AI.

• Implemented character skills and particle effects.

• Implemented character skill tree.

• Implemented the tutorial level.

• Designed the towers.

Description:

I use 27 mass points in a cube object and two anchor points linked by springs vertically, horizontally, and diagonally between adjacent points.
Physically-based simulation is a solo project and I complete the project in 2 days.

Little Buddy Simulator is a 2D puzzle solving game with multiple endings. There is a value showing your evilness. You can either complete other slime's request to get reward and decrease your evilness or kill other slimes to get their items but increase your evilness. Different evilness leads to different endings and might change NPCs behaviors.

Little Buddy Simulator is a game developed by a team of 2 programmers in 3 months.
It was built by custom component based 2D engine in C++ using SFML.

Title:

Gameplay programmer / Engine programmer

Role:

• Built entity creation(Entity Factory) and entity manager.

• Built 2D collision physics.

• Built 2D CPU side particle system.

• Built finite-state machine for AI behavior.

• Implemented inventory system.

Magieval is a 2D real-time single player vs AI battle royale game where the player needs to explore the world, gather resource and weapon yourself, and then survive to the end. There is a safe zone shrinking to force the players to a smaller region for combat. All other competitors are AI and they also have similar behaviors like the player.

Description:

I did Hierarchy task network planning for my AI final project.
I built the environment as a RTS game, and the player need to gather the resource or build the factory. Any action can be seperated into several steps based on the current resource and knowledge. If the world has changed caused by other situations, the character will reschedule his plan to meet the goal.

Description:

I use A* for pathfinding in a grid-based map. I also use straight line to optimize. Rubberbanding to decrease the number of the redundant nodes. Catmull-Rom spline to make the path more smooth.

I also did some terrain analysis in this project.
Closest wall: showing the correct ratio color based on the distance to the closest wall.
Visibility: showing the correct ratio color based on the visibility to all the other nodes.
Visible to player: showing the correct ratio color based on the view from the player position.
Search: showing the correct ratio color based on the time of the player's view.

And I did occupancy map for the project.
Propagation: spread out the color.
And I implemented the hide and seek based on the occupancy map.
