how does inside box work
int inside_box(int x, int y, int left, int up, int right, int down);this is what it says in a dink help program but what does it all mean i know the first two but i dont know int left,int up, int down,int right.
I am trying to make a key which i have in my inventory open a gate when i am standing in front of it.

For what you are doing, you want int x and int y to be the x and y of dink. int left, int up, int right, and int down are the left, top, right, and down sides of the box. For example:
int &dx = sp_x(1, -1);
int &dy = sp_y(1, -1);
&junk = inside_box(&dx, &dy, 30, 250, 200, 310);
In this case, the upper right corner of the box is (30, 250) and the lower right is (200, 310). &junk will be zero if not in the box and one if it is.
Good luck.

I still cant seem to get it to work
this is my item_key sript that i am using:
//item key
void main( void )
{
&dx = sp_x(1, -1);
&dy = sp_y(1, -1);
&junk = inside_box(&dx, &dy, 470, 188, 516, 260);
}
void use( void )
{
if (&player_map == 671)
{
if (&junk == 0)
{
say("I need to find the right place",1);
return;
}
if (&junk == 1)
{
say("it worked",1);
sp_active(&temphold, 0);

}
}

}
can you tell me whats wrong with it please

You need to initialize &junk (unless it is a global variable, which it doesn't need to be)
use
int &junk....
instead of just
&junk
in the main(void) procedure

Also, I think that the inside_box and getting dink's position needs to be in the "use" procedure - I don't think it runs the "main" procedure with each use. At least, I couldn't find any item scripts that had stuff other than int variables in the main proc.

So, unless I'm wrong, you could just put the three lines you have in your main proc after your first "if" statement, and add int &junk to your main procedure (or just put int before the &junk in the inside box line)
Good luck
