My "program" keeps crashing!! pls help!!
I tried to make a small "program" where a person moves around the screen and you control him, but every time i run it, it keeps crashing.
Here is my source code please help.
//MAIN.CPP
#include<allegro.h>
#include"Hero.h"
using namespace std;
BITMAP *buffer;
Character hero;
//inserting images (sprites)
void Setup(){
buffer=create_bitmap(640,480);
hero.SetImagesLeft("normalstand2.bmp","walkleft1.bmp","walkleft2.bmp");
hero.SetImagesRight("normalstand.bmp","walkright1.bmp","walkright2.bmp");
hero.Show(screen);
}
//Movement for the player
void movePlayer(){
if( key[KEY_LEFT]){
hero.MoveOnX( LEFT, buffer, screen);
} else if( key[KEY_RIGHT]){
hero.MoveOnX( RIGHT, buffer, screen);
}
}
//Main details
int main(int argc, char *argv[]){
allegro_init();
install_mouse();
install_keyboard();
set_color_depth(16);
set_gfx_mode( GFX_AUTODETECT, 640,480 , 0, 0);
Setup();
while( !key[KEY_ESC]){
rest(50);
movePlayer();
}
return 0;
}
END_OF_MAIN();

When i run the program it immediately crashes saying that the program has stopped working.
Use the debugger to isolate the problem function by using breakpoints before and after each function to see how far it gets. It has to be one of those first few calls in main()...
