JoGa OP User Joined: Dec 2003 Posts: 988 Germany, Magdeburg	Hey in a application i create panels during runtime. Their pointers are saved in a array like (i hope, this is right): Code: array_panels_d_elemente[i] = (int*)pan_temp; If the user right-clicks on a panel, i have to check, if its a panel, which was saved in the array. I wanted to use mouse_panel for this. But I have some problems with the comparison . how can I check if the pointer of the mouse_panel "points" on a panel, which is saved in the array? Code: int i; for(i=0;i<50;i++) { if(mouse_panel !? array_panels_d_elemente[i]) // my problems { //.... } } Could someone help me how to search for the pointer right? Thanks Last edited by JoGa; 06/16/13 22:06.

Code:

#define MAX_PANELS 500 // ? as many as you need

PANEL* array_panels_d_elemente[MAX_PANELS];
var totalPanels = 0;

if(totalPanels < MAX_PANELS)
{
   array_panels_d_elemente[totalPanels] = pan_create(.....);
   totalPanels += 1;
}



if ( mouse_right && mouse_panel != NULL )
{
    int i;
    for(i=0;i<50;i++)
	{
	    if(mouse_panel == array_panels_d_elemente[i])
              { 
                // panel found do stuff here //
 
                break; // stop the loop
              }            
 	} 
}

(JustSid just informed me that it is perfectly fine to use ints) You can however save them in vars, for instance as follows: entity-skills are a var skill[100] array, thus writing my.skill70 = ent_create(...); and my.skill71 = pan_create(...); or PANEL* pnl_tmp = pan_create(...); my.skill71 = pnl_tmp; is perfectly fine. You can then later retrieve the pointer by a simple cast: ((ENTITY)my.skill70).x = 10; or handier as you = (ENTITY)my.skill70; pnl_tmp = (PANEL*)my.skill71; The last two typecasts should not be necessary (you = my.skill70; should work, too) but I like to do it that way.
