btw, sleep is a non-standard function, so may not be supported by all C compilers. You also don't need to worry about the palette when using anything but 8 bit graphics.

No, the 1,2,3,4(etc) images are text. I cronometered myself reading each one, and puted the sleeptime accordinlgy. It was taking longer than the sleeptimes. So, the final code is supposed to be this, right?: 1#include <stdio.h>
2#include <allegro.h>
3
4void load_and_display_bitmap( const char* filename, int x, int y, int delay )
5{
6 BITMAP *bmp = NULL;
7 bmp = load_bitmap( filename , NULL);
8 if ( bmp )
9 {
10 draw_sprite(screen, bmp, x, y);
11 /* Consider to use rest( delay ) instead of sleep( delay ) here.
12 * rest() takes a value in milliseconds, while sleep takes seconds.
13 */
14 sleep(delay);
15 destroy_bitmap(bmp);
16 } else
17 {
18 set_gfx_mode(GFX_TEXT,0,0,0,0);
19 allegro_message("Can't load %s\n", filename);
20 }
21}
22
23int main( char** args )
24{
25 int sleepTime;
26 int bmp;
27 /* STEP 1

29 * Setup allegro, create window and init keyboard handler

31
32 /* FIX ME: Check return codes of all these functions */
33 allegro_init();
34 set_color_depth(24);
35 set_gfx_mode(GFX_AUTODETECT_WINDOWED, 800, 600, 0, 0);
36 install_keyboard();

It isn't the same slow, but it is slow (when I say slow, I mean it is passing the sleeptimes). Am I missing something? |

jpcanaverde said: So, the final code is supposed to be this, right?: The last parameter of the function Spellcaster wrote for you is the delay. Instead of passing 20 to it, and then sleeping again (say for 40s)between calls, just add the second sleep time to the first (and pass 60 to the function). You also don't need to keep destroying the bmp bitmap in the main loop, as you never even use it (you can actually remove it's declaration). Quote: It isn't the same slow, but it is slow (when I say slow, I mean it is passing the sleeptimes). Am I missing something? Sleep probably isn't very reliable. You could try using Allegro timers instead.

No, the final code is supposed to be what I posted above. Hm? And if you really want seconds, replace the call to sleep( delay ) BTW you can click any allegro and standard-c function in the code blocks here to see the man page for them, which might give you further info. -- |

Now I got it: Delay is the sleep! I didn't copy-paste your code because I thought I had to put the SleepTimes too. And it was taking too long because I was wating 2 times. OK, thank's. Now it works! Woo hoo! EDIT: It just works on my computer, with Ubuntu. I tried with Windows in a second computer and with Ubuntu on a third computer, but they don't work! I don't get it! What's happening? I really don't want to take my laptop to school... |
