Instance question

[michaelsoftman]

I have a question.  I was checking out the Endless Tower instance, and I noticed something.  The warp commands just have 1@tower as the warp destination, for example.

 

When a map is instanced, it adds numbers from 000 to 999 in front of the name, like 0011@tower.

 

So how does the script know what instance to warp you to, if you just set the warp to 1@tower?  How does it know to send you to 001 or 027?  Is there part of the script I am not understanding right, or does it just automatically detect if you have an instance and warp you to the right one?

The server will automatically warp an instance party member to the instanced version of the map

pc.c

	if( map[m].flag.src4instance && sd->status.party_id && (p = party_search(sd->status.party_id)) != NULL && p->instance_id )
	{
		// Request the mapid of this src map into the instance of the party
		int im = instance_map2imap(m, p->instance_id);
		if( im < 0 )
			; // Player will enter the src map for instances
		else
		{ // Changes destiny to the instance map, not the source map
			m = im;
			mapindex = map_id2index(m);
		}
