[Trigger] Managing Unit Collisions with Triggers?

[Firefly-]

At it's core, this began with me wanting to code Wind Walk using triggers, just to see if I could.

Now, I know exactly how I could do this, but now I don't want to, I just want to edit unit collision with triggers alone. If I remove collision completely, then the unit can move through trees (undesirable).

Is there a way to edit JUST unit collision, so that said unit can move through other units but NOT through trees or other obstacles?

you can turn collision on/off depending on what is near but it will need multiple actions tracking if its near water or trees, water is the longest one but i did it myself and i can track if a unit is near water or not though it may be a bit laggy since its gui.

So what if said hero comes near both a tree and a unit. =X

Then you should wonder how that unit got there in the first place. Seeing as how units can't really walk "through" trees
