Instancing Question

[Arcenciel]

I'm trying to learn how to create instances so I decided to look at npc/instances/OrcMemory.txt for a model. I'm stumped however by this section.

for( set .@i, 1; .@i <= 2; set .@i, .@i + 1 ) {
if( instance_attachmap(.@i + "@orcs", .@instance) == "" )
break;
}
if( .@i < 2 ) {
instance_destroy(.@instance);
close;
}

Is 2 used because 1@orcs and 2@orcs are the original maps and that shouldn't be used for the instance or is it because of other reasons?

it breaks out of the loop when instance fails to attach, in that case .@i will be lower than 2 (because you are trying to attach 2 instances), and it deletes the whole instance set with instance_destroy

Oh, I get it. Thanks.
