Nvm I fixed my issue with finding the angle between 2 objects and using it with SDL_RenderCopyEx();

 

Here is my function:

 

double find_angle(float x1, float x2, float y1, float y2)
{
double degrees;
 
// Get the angle between point (x1,y1) and (x2,y2)
degrees = atan2(y2 - y1, x2 - x1) * 180/PI;
 
return degrees;
}
 
and the call:
 
angle = find_angle(target.y, y, x, target. x);
 
Im not sure why its working since the variables are mixed up where they are supposed to be, but I kept trying them in different positions and its working,
