Introduction

Demo:

game_v0.1.2.mp4

This is a simple rougelike game developed based on SDL3 and my ECS framework.

This game is a 2D top-down rougelike survivor roguelike. The objective is to survive through endless waves of enemies. Before each wave starts, you need to upgrade the enemies. Then you have half a minute to survive the relentless attacks of the enemies. During this time, you can upgrade yourself, collect resources, and establish powerful defensive structures.

Since the game is based on highly scalable ECS framework, and the main game information can be configured through JSON, you can easily add more monsters, items, and modify the AI, etc.

Features

The project used the following technologies:

• ECS(Entity-Component-System) architecture, providing highly reusable modules and efficient execution speed
• QuadTree to accelerate collision detection
• SceneGraph to manage the logical relationship between objects and the rendering order
• BehaviorTree to manage the AI Logic of enemies and defense towers
• Lazy Theta* pathfinding algorithm, providing smoother movement compared to A*
• JSON is used to configure game settings, monster information, item information, upgrade rewards, monster upgrade information, behavior tree, etc.

ECS, QuadTree and other modules primarily rely on my wheel library. Refer to the library's documentation for more details.
