 I cant see the physikal movement
 Max S Member #5,508 February 2005 Hifirst of all, sorry for my bad English. I try my best^^.i wont to write a very simple code, that could calculate a physic variable with a function.this is the simplest version of the code:```int fall(int *h) { int g = 9; int t = 10; if (h > 0) { *h = (g / 2 * (t * t)); } } ``` this is a very simple kind to calculate it!! but first i wont to try if its work trough given consts and after it I will change the code so, that it could calculate the time and the high by itselfbut its very simple, thers a picture wich should fall down, but if i run the code, the ball is on the ground. i think i need timer or extra operators for the movement, which reduce the fps. But i think everybody who worked with graphics movement, know what i mean.
 piccolo Member #3,163 January 2003 ```int fall(int &h) { int g = 9; int t = 10; if (h > 0) { h *= (g / 2 * (t * t)); } } ``` or ```int fall(int &h) { int g = 9; int t = 10; if (h > 0) { h = h*(g / 2 * (t * t)); } } ``` wow-------------------------------i am who you are not am i

no this istn what i mean

look this is the code

 1 int fall(int *h) { 2 3 int g = 9; 4 int t = 10; 5 6 if (h > 0) { 7 *h = (g / 2 * (t * t)); 8 } 9 } 10 11 int main(int argc, char *argv[]) 12 { 13 allegro_init(); 14 install_keyboard(); 15 16 set_graphic_mode(); 17 if (set_graphic_mode <= 0) { 18 allegro_message("Unable to set graphic mode!"); 19 exit(0); 20 } 21 22 int x = 0; 23 int y = 0; 24 25 BITMAP *bild = load_bitmap("bild.bmp" , NULL); 26 27 while (!key[KEY_ESC]) 28 { 29 acquire_screen(); 30 clear(screen); 31 fall(&y); //y get the value of h 32 blit(bild,screen, 0, 0, x, y, bild->w, bild->h); 33 release_screen(); 34 readkey(); 35 36 destroy_bitmap(my_pic); 37 38 } 39 }END_OF_MAIN()

if i start it
the picture is imediatly at the ground, whithout that i can see how its falls

 gnolam Member #2,030 March 2002 My god man, learn to use indentation! The problems (well, besides the complete lack of indentation) are twofold:1) is that you don't time your code. Read the FAQ.2) t starts at 10, making h start at 450, which, depending on the graphics mode you've set, may be outside the screen.Oh, and I know capitalization exists in German, so please use it in English as well. -- Move to the Democratic People's Republic of Vivendi Universal (formerly known as Sweden) - officially democracy- and privacy-free since 2008-06-18!
 Max S Member #5,508 February 2005 Ok Ok sorry, but Im in stress here.Ok i try it.And if i get a problem, I will knew whom I have to ask ^^

I think it'd be 500, since he's using ints. Or is it 400? I can never remember if integer division rounds up or down.@Max S: Timer logic will help maintain the proper speed on varying computers. You also need to understand the logic of a game loop. You only need to do a portion of your "fall" function each loop. You can add a float value to multiply the final calculation to make it only do 10% of the calculation per game loop. There are methods, I'm just rambling about some food-for-thoughts. ------------Solo-Games.org | My Tech Blog: The Digital Helm
 Max S Member #5,508 February 2005 At the beginn I sad that this is just a simple version of the code.When it's done, the funktion calculate the h und how long it needs to fall, by it self.But first i will try to make this counter work, this is the harder part for me.
