开始定义宏 SDL_MAIN_USE_CALLBACKS 就是使用SDL_main.h头文件方法,使用SDL_main.h头文件之后就不能使用 int main(int argc,char **argv)函数了,只能自己定义使用这四个函数。需要安装SDL3才能使用这些函数,我在SDL2 的SDL_main.h中没有发现这四个函数 为什么不能自己定义main作为程序的开始,而是使用这四个...

Using the alternative #define SDL_MAIN_USE_CALLBACKS, the main use case for SDL_ConvertEventToRenderCoordinates is broken. This is because the signature SDL_AppResult SDL_AppEvent(void *appstate, const SDL_Event *event) requires a const ...
