Introduction

As the leader of a troop of pigments, draw your orders on the screen and conquer other colors. Paint enemy camps in your hue and defend your territory during intense and colorful battles. Upgrade your army and your base’s defenses using technological advances in color.

The Chinese version (expected release in late 2018) is greatly re-engineered to support MOBA while keeping the core gameplay. You can fight with other players in real-time in a 1v1 or 3v3 mode. We also re-designed the skill system and the technology tree to make the MOBA experience more captivating. A replay system is added based on the MOBA framework. Players could review their battle records and learn from other players. A guild system and an in-game chatting system are developed to enhance social experiences.

Duties

• Designed and implemented a lockstep system to achieve multiplayer real-time PVP (Player Versus Player), including a two-layer structure to decouple the simulation loop from the rendering loop, a fixed-point math lib to make the game logic fully deterministic across all the machines and a Unity-like Coroutine.
• Developed a replay system based on the lockstep system, which could record a 5-min game battle in a tiny file (less than 10KB).
• Designed and implemented a fast and reliable networking framework with UDP and KCP (an automatic repeat request protocol), supporting smooth real-time PVP in a poor network connection (250ms+ delay, 100ms+ jitter) by combining with client-prediction.
• Designed and implemented a hot update system to allow updating data without re-downloading the client.
• Optimized the performance to support low-end devices to run smoothly in a game battle involving 1000+ entities.
