some of the parameters in toggling images have me confused. especially paramters *id and *ons in Toggle() and ToggleSet(); Can anyone please clarify those for me?

[Goldeye]

Code: Show/Hide void (*Toggle)(const Target *t, int id, int on);

The target's obvious, though apparently passing an arena changes the defaults not the active state for everyone there. <shrug>

id is the object id, on is boolean for whether it's on or not. 1=on 0=off.

Code: Show/Hide void (*ToggleSet)(const Target *t, short *id, char *ons, int size);

This is a way of efficiently passing a lot of parameters to Toggle. Toggle probably would repeat stuff that only needs to be done once per target, so this way you can a set of objects without that inefficeincy.
id and ons are both arrays. size is the number of objects in that array.

Think of it (functionally, though the details inside are different, obv) as this:

Code: Show/Hide void ToggleSet(const Target *t, short *id, char *ons, int size) {    int i;    for(i=0;i<size;i++)    {       Toggle(t,id[i],ons[i]);    }

Example:
This code turns on objects 3 and 2 and turns 7 off.

Code: Show/Hide short id = { 3, 7, 2 } char ons = { 1, 0, 1} size = 3; objects->ToggleSet(t, id, ons, size);

Very nice example. I never realized the relation between id and ons. obviously they correspond. Thank You!

I think they call them parallel arrays.

Code: Show/Hide short id[] = { 3, 7, 2 }; char ons[] = { 1, 0, 1 }; objects->ToggleSet(t, id, ons, sizeof(id) / sizeof(id[0]));
