Change pathability of an area

[Hugget Sukker]

I'm a noob in SCII's editor. I've tried using pathing blockers, but their effect don't seem to remove by triggers. I can't find a way of making areas pathable/unpathable by trigger actions. I guess I could go ahead and make an invisible blocker unit in the data editor, but I reckon there should be a smarter way, uhu?
Can anyone tell me the answer?

Remove Doodads in Region says:

Instantly removes all doodads of the specified type from a game region. If the doodad being removed has a footprint, that footprint will still linger, even though the doodad's actor has been destroyed.

Use dynamic pathing blockers instead of regular ones, these are counted as units in the editor and can be removed by triggers.

Oh- I thought I'd searched for "pathing" in units - but now I see. Heh, better to be sure you did rather than to think you did
Typical mistake, so extra thanks to you for helping Darkness-4ever
