Hello guys, someone know how to create a bitmap and attach it in the mouse? 1#include <iostream>
2#include <allegro5/allegro.h>
3#include <allegro5/allegro_native_dialog.h>
4
5const int screenHeight = 800, screenWidth = 572;
6
7int main(int argc, char *argv[]){
8
9 ALLEGRO_DISPLAY *display = NULL;
10 ALLEGRO_EVENT_QUEUE *event_queue = NULL;
11
12 if(!al_init()) {
13 al_show_native_message_box(NULL, NULL, NULL, "Allegro 5 could not initialize successfully", NULL, NULL);
14 return -1;
15 }
16
17 display = al_create_display(screenHeight, screenWidth);
18 if(!display) {
19 al_show_native_message_box(display, "Sample Title", "Display Settings", "The window wasn't created successfully!", NULL, ALLEGRO_MESSAGEBOX_ERROR);
20 return -1;
21 }
22
23 event_queue = al_create_event_queue();
24 if(!event_queue) {
25 fprintf(stderr, "failed to create event_queue!\n");
26 al_destroy_display(display);
27 return -1;
28 }
29
30 al_register_event_source(event_queue, al_get_display_event_source(display));
31
32 al_clear_to_color(al_map_rgb(0,0,0));
33
34 al_flip_display();
35
36 while(1)
37 {
38 ALLEGRO_EVENT ev;
39 ALLEGRO_TIMEOUT timeout;
40 al_init_timeout(&timeout, 0.06);
41
42 bool get_event = al_wait_for_event_until(event_queue, &ev, &timeout);
43
44 if(get_event && ev.type == ALLEGRO_EVENT_DISPLAY_CLOSE) {
45 break;
46 }
47 al_clear_to_color(al_map_rgb(0,0,0));
48 al_flip_display();
49 }
50
51 al_destroy_display(display);
52 al_destroy_event_queue(event_queue);
53
54 return 0;
55}
Thanks |

First I would try to load a bitmap and display it. This is what you need for that: Then you can try the mouse stuff: And you could check out the Allegro examples. And please use <code> </code> tags |

I can't see an al_draw_text call in your code, can you see in the debugger where it is? It looks like font is NULL, so something is probably not initalized. You could also look at the value of the ustr parameter, maybe it's an error message. |

Mmmm... I don't know what's the problem |

Are you calling al_draw_text, or is Allegro? |

I think so... i think is the file that i include in Xcode, i don't have any problems with the other allegro functions, but i have problems with the images and with the fonts. I smell something fishy... |

It's very hard to help if you don't provide any concrete information |

You should probably check the return value from al_load_bitmap. |

What? Sorry, but i didn't understand |

Do something like this: player = al_load_bitmap("resources/player.png"); if(!player){ al_show_native_message_box(NULL, NULL, NULL, "Failed loading player.png", NULL, ALLEGRO_MESSAGEBOX_ERROR); return -1; }

Then you have to learn how to debug |

Solved, i haven't put the complete direction in the al_load_bitmap(file); hahaha (in the tutorial that i see it isn't necessary). |

i have the al_draw_text call, but I think is a problem with the files...
