//This example program is created by thecplusplusuy for demonstration purposes. It's a simple mario like side-scroller game:

//Free source, modify if you want, LGPL licence (I guess), I would be happy, if you would not delete the link
//so other people can see the tutorial
//this file is base.cpp
#include "base.h"

//just make the collision function
bool baseclass::collision(SDL_Rect* rec1,SDL_Rect* rec2)
{
    if(rec1->y >= rec2->y + rec2->h)    //if rec2 is upper than rec1 there is no way to be a collision
        return 0;   //so return 0
    if(rec1->x >= rec2->x + rec2->w) //if rec2 is more to the left than there is no way to be a collision
        return 0;
    if(rec1->y + rec1->h <= rec2->y)    //if rec2 is under rec1 no collision
        return 0;
    if(rec1->x + rec1->w <= rec2->x)    //if rec2 is righter then rec1 there is no way for collision
        return 0;
    return 1;   //if all fails, we have a collision
