Function Documentation

int main

(

)

(Attempt to) Initialize SDL libraries so that we can use SDL facilities and eventually make openGL calls. Exit if there was an error.

` (Attempt to) Initialize SDL_image libraries with IMG_INIT_PNG so that we can load PNG textures for the entities and stuff.

(Attempt to) Initialize SDL_mixer libraries for loading and playing music/sound files.

unsigned int millis

void

)

millis

We've encountered many problems when attempting to create delays for triggering the logic function. As a result, we decided on using the timing libraries given by <chrono> in the standard C++ library. This function simply returns the amount of milliseconds that have passed sine the epoch.
