Heh, one more thing, you may want to put a check in at the very bottom of that statement to say that if the total for the modifier (or duration) == 0, to strip that affect and reassign the ->next pointers appropriately

Richard Lindsey -----Original Message----- From: Richard Lindsey Sent: Thursday, April 15, 2004 12:28 PM To: [EMAIL PROTECTED]; [email protected] Subject: RE: Combining Affects It's something you'd have to write yourself, but you can do something like this... int total, apply; AFFECT_DATA *paf, *paf_next, *paf_next2; for ( paf = obj->affected; paf != NULL; paf = paf->next ) { apply = paf->location; total = paf->modifier; for ( paf_next = paf->next; paf_next != NULL; paf_next = paf_next->next ) { paf_next2 = paf_next->next; if ( paf_next == paf->next && paf_next->location == paf->location ) { total += paf_next->modifier; paf->next = paf_next2; free_affect(paf_next); } if ( paf_next2->location == paf->location ) { total += paf_next->modifier; paf_next->next = paf_next2->next; free_affect(paf_next2); } } paf->modifier = total; } I think that should work, in theory anyway, it'll cycle through the affect list, starting with the first, it'll record that apply number and check the rest of the list for duplicates... any duplicates it finds it'll add the modifier to total and destroy that affect, then loop on to (the newly assigned) next affect in the chain until it hits the end, the go to the 2nd element in the list and check from there on in the same way... feel free to point out any bugs you see in this (anyone) as I kind of thought it up on the fly but would like to put it into mine also :D Richard Lindsey -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Thursday, April 15, 2004 12:12 PM To: [email protected] Subject: Combining Affects I want to combine the affects on 2 items. For example - Item 1 has an 'addaffect' of +100 hp, and Item 2 has an 'addaffect' of +20 hp. When 'combined' by the player, the new item will have +120 hp. Is there something in the ROM code that I am missing that does this, or I have to write one myself? If so, any help would be good.
