Well, my idea principally is this:

 

· If an specific enemy touches an item the item disappear, and when the item disappear -> Play a certain SFX

 

 

 I need this :( please I need help. :(

Try this:

D0: NPC ID for enemy that can steal items.
D1: Sound effect for stealing.
D2: The time that the npc carries item around before hey vanish, in seconds.
Accepts decimal values, so 1.250 is 1.25 seconds.
 

const int NPC_MISC_HOLDING_ITEM = 12; 

ffc script BasicStealItem{
	void run(int npc_ID, int stealsfx, float dragdur){
		npc n; item i; int q; int w; int e; int r; itemdata it;
		if ( !dragdur ) dragdur = 1; 
		int itemlist[]={	IC_RUPEE, IC_HEART, IC_ARROWAMMO, IC_MAGIC, IC_BOMBAMMO};
		while(true){
			for ( w = 1; w <= Screen->NumItems(); w++){
				for ( q = 1; q <= Screen->NumNPCs(); q++) {
					n = Screen->LoadNPC(q);
					if ( n->isValid() )	{
						if ( n->ID == npc_ID && !n->Misc[NPC_MISC_HOLDING_ITEM]) {
							i = Screen->LoadItem(w);
							if ( i->isValid() ) {
								if ( __DistX(n,i,4) && __DistY(n,i,4) ){
								
									it = Game->LoadItemData(i->ID);
									for ( e = 0; e < SizeOfArray(itemlist); e++){
										if ( it->Family == itemlist[e] ) {
											n->Misc[NPC_MISC_HOLDING_ITEM] = 1; 
											for ( r = 0; r < (dragdur * 60); r ++ ) {
												i->X = n->X;
												i->Y = n->Y;
												Waitframe();
											}
											Game->PlaySound(stealsfx);
											Remove(i);
											n->Misc[NPC_MISC_HOLDING_ITEM] = 0;
										}
									}									
								}
							}
						}
					}
				}
			}
			Waitframe();
		}
	}
	bool __DistX(npc a, item b, int distance) {
		int dist;
		if ( a->X > b->X ) dist = a->X - b->X;
		else dist = b->X - a->X;
		return ( dist <= distance );
	} 
	bool __DistY(npc a, item b, int distance) {
		int dist;
		if ( a->Y > b->Y ) dist = a->Y - b->Y;
		else dist = b->Y - a->Y;
		return ( dist <= distance );
	}

Replace it with int npc_ID

Replace it with int npc_ID

No... I forgot to declare the param as an int.

Error T29: 'That pointer type does not have a variable isValid

Updated above.

Another error now on the line 9   "That pointer type does not have a FUNCTION isValid" D:

[Timelord]

I see what I did there. I had the casing right originally, but forgot the parens.

error t29: that pointer type does not have a variable class.

 

Oggg

[Timelord]

Fixed above.

[Lejes]

Items also don't have a Type variable. The IC_ constants are meant for item families, which you'll have to load itemdata for.

Sigh. Another inconsistent thing for me to fix in ZScript. There is no reason whatever, that item->Type shouldn't be a thing, and pointer->Class should exist too, as that's how ZC defines them in the editor, which is why when I was making these--on me phone--I used that.

Life tip: Don't become old, and senile. I very rarely use the class of objects to do...anythibg. I typically use object->ID, as my applications are far less generic. This [i]should[i] be done now, and if it isn't, it's going to wait until I can sit in front of a laptop.

The main reason that I used item classes here, is so that CerealGuy didn't need to make a huge list of all the items to affect. I originally wrote it with item->ID, and then decided that the set-up would be too much work for him; and I set it to the common drops, instead of single items, instead.

It also shortens the for loop quite a lot.

Change itemclass to itemdata, and then I'll shoot meself in the foot again. Fixed above.

ZASM uses 'itemclass', by the by. Been staring at that too much lately, apparently. Thinking about it, that's probably why item->Class/item->Type isn't a thing, as itemdata began life, as itemclass.
