I am quite frustrated. For sum reason I cannot get any bitmap loading programs to work with Dev C++. It compiles fine but everytime the program runs it just gives me a "this program has preformed a illegal operation" and closes. I have located the bitmaps in the same folder as the program. I dunno here is my source
Code:#include <allegro.h> // You must include the Allegro Header file /////////// // TIMER // /////////// volatile long speed_counter = 0;//A long integer which will store the value of the //speed counter. void increment_speed_counter() //A function to increment the speed counter { speed_counter++; // This will just increment the speed counter by one. } END_OF_FUNCTION(increment_speed_counter); //function /////////////////////// // The Main function // /////////////////////// int main(int argc, char *argv[]) { allegro_init(); // Initialize Allegro install_keyboard(); // Initialize keyboard routines install_timer(); // Initialize the timer routines LOCK_VARIABLE(speed_counter); //Used to set the timer - which regulates the game's LOCK_FUNCTION(increment_speed_counter);//speed. install_int_ex(increment_speed_counter, BPS_TO_TIMER(60));//Set our BPS set_color_depth(16); // Set the color depth set_gfx_mode(GFX_AUTODETECT, 640,480,0,0); // Change our graphics mode to 640x480 BITMAP *frame1 = load_bitmap("frame1.bmp", NULL); // Declare a bitmap and Load our picture in one statement BITMAP *frame2 = load_bitmap("frame2.bmp", NULL); BITMAP *frame3 = load_bitmap("frame3.bmp", NULL); BITMAP *buffer; //Declare a BITMAP called buffer. buffer = create_bitmap(640,480); //Create an empty bitmap. int my_pic_x = 0;// Holds our pictures X coorinate int my_pic_y = 0;// Holds our picture's Y coordinate int frame_counter = 0;// A counter for which frame to draw while(!key[KEY_ESC])//If the user hits escape, quit the program { while(speed_counter > 0) { if(key[KEY_RIGHT])// If the user hits the right key, change the picture's X coordinate { my_pic_x ++;// Moving right so up the X coordinate by 1 } else if(key[KEY_LEFT])// Ditto' - only for left key { my_pic_x --;// Moving left, so lower the X coordinate by 1 } else if(key[KEY_UP])// If the user hits the up key, change the picture's Y coordinate { my_pic_y --;// Moving up, so lower the Y coordinate by 1 } else if(key[KEY_DOWN])// Ditto' - only for down { my_pic_y ++;// Moving down, so up the Y coordinate by 1 } speed_counter --; frame_counter ++; //Increment our frame counter at the same speed of the //speed counter if(frame_counter > 240) { frame_counter = 0; } } acquire_screen();// Get the screen //In the first second, draw the first frame if(frame_counter < 60)//Less than a full second { draw_sprite(buffer, frame1, my_pic_x, my_pic_y);//Draw the first frame } else if(frame_counter >= 60 && frame_counter < 120)//Between 1 and 2 seconds { draw_sprite(buffer, frame2, my_pic_x, my_pic_y);//Draw the second frame } else if(frame_counter >= 120 && frame_counter < 180)//If we are between 2 and 3 seconds { draw_sprite(buffer, frame1, my_pic_x, my_pic_y);//Draw the first frame again, //to acheive better effect } else// If we are over 3 seconds { draw_sprite(buffer, frame3, my_pic_x, my_pic_y);//Draw the last frame, } blit(buffer, screen, 0,0,0,0,640,480);//Draw the buffer to the screen clear_bitmap(buffer); release_screen();// Release it } destroy_bitmap(frame1);//Release the bitmap data destroy_bitmap(frame2);//Release the bitmap data destroy_bitmap(frame3);//Release the bitmap data destroy_bitmap(buffer);//Release the bitmap data return(0);// Exit with no errors } END_OF_MAIN();
