Question

I know you may regard this post as another duplicate, while it’s not. It’s not a duplicate because my code is different than others, and nobody else’s post (that I have seen) has solved my problem.

Here is my code:

#include "sprite.h"

SDL_Surface * SPRITE::screen;
int player;
void DrawPlayer(int x, int y) {
    SDL_Rect rect = {x,y,20,20};
    SDL_FillRect(SPRITE::screen, &rect, 0x00CC00);
}
DrawPlayer(20,20);

The error is on the line DrawPlayer(20,20);

Answer 1

You are not calling DrawPlayer() from within any function.
