I am not sure if this is possible at the moment, so i will post it here just in case.
The other night, when working on spawning, an idea poped into my head. Wouldn't it be nice if i could place several spawners with the same spawns in different locations, and have only one of the spawners spawn part or all of the entries.
Example...
--------------------------
Say i have a dungeon, where i want to spawn a liche in on of three possible locations. Placing one spawner encompassing all the locations will not work since the Lich can spawn in any other area the spawner covers.
So what if i could place one spawner in each room, having a Lich defined as the mob to spawn ( or any other combination of mobs ). Then when the times comes to spawn, one of the spawners ( randomly determined, or a manually set order ) spawn the Lich, while the rest do nothing, since they will know it is spawned by one of the other linked spawners. In other words, three spawners working as one
--------------------------
Being able to set it to randomly or a pre defined order will open up for alot of cool spawn options. I guess this is already possible somehow, but involve alot of parameters to make possible. With a link option, it would be easily accomplished by just setting a few props.
If this is already easily available, then a good tutorial on the subject would be welcome
