我还没用过SDL2进行手搓引擎

就是想做个引擎玩玩。
这个是本地native c++编译后运行，以前做的是便于网页运行的简易JS（无硬件加速）
实际我使用suika3和renpy。

The issue describes a desire to create a game engine using SDL2 and C++, referencing existing engines like Suika3 and Ren'Py. Start by examining the repository's current structure to see if there is any existing engine code or Lua scripting framework. Look for any build files or examples to understand the project's current state. The goal is to define a clear scope for what 'making an engine' entails in this context.
