Loop helpers¶

AP_Init(AP_INIT_VIDEO | AP_INIT_AUDIO);
AP_CreateWindow("Title", 1280, 720, AP_WINDOW_RESIZABLE);
while (AP_IsRunning()) {
  AP_PumpEvents();
  AP_SetDrawColor(0.1f, 0.1f, 0.1f, 1.0f);
  AP_Clear();
  /* draw */
  AP_Present();
}
AP_DestroyWindow(NULL);
AP_Quit();

Color¶

AP_SetDrawColor(r, g, b, a) takes floats in 0–1. AP_C4(r, g, b, a) builds an AP_Color for 3D and sprites.
