[General] selective unit collision

[IronBladeClan]

I was reading that the sc2 colossus unit has multiple collision layers, so it still collides with big units like other colossi, but not with smaller units. I guess wc3 works differently, so to get the same effect would require some kind of workaround.

Is there a way to use the trigger system/jass/Lua to make a unit that can pass through all other units (like windwalk) EXCEPT for units of its own type?

If not...what about a workaround like making the model really tall and messing with collision shapes on the model so that it only collides with things that have their collision shape thing at a similar height? I don't know anything about model editing, so I could be completely misunderstanding what collision shapes are.

You can play around with Aeth - Ghost (visible).
See this thread.

The collision shape that you do in modeling is purely in order to determine how easy it is to click/box select the unit, it's independent from the collision size of the ingame unit per se

I ran across that thread before I made this one, but it says "ghosts can walk through ghosts," so that won't work for me. I need something like "ghosts can't move through each other."

Also, ghosts can only have units pass through them, but can't actively move through other units (besides ghosts).

Ah, I see, thanks for the clarification.


Anyone else know if there's any JASS or Lua functions that might be helpful here?
