Function returning entered region?

[mango]

Hi,

I'm working on a simple GUI trigger for entering buildings. Rather than instant-moving units between regions to enter houses, I'm using a framework kit made of walls and roofs so that players can actually ENTER buildings. I'm now working on an efficient way to hide the roofs when a unit enters the region.
I'm trying to write the whole system in 2 triggers; one for entering the house (region) and one for exiting. I'm using many of the Unit Enters Region event and inserting each individual house region, so the trigger fires every time a player enters ANY house. The problem now is getting ONLY the roof of the ACTUAL ENTERED house to hide -- I already know I can do this using a handful of If/Then/Else actions, but that's really inefficient.

My question is (since I am no JASS expert): is there a call function in JASS that would allow me to return the entered region from a "unit enters region" event? Maybe something like "Call GetEnteredRegion(udg_***...)" and then I could save it as a variable?? I really have no idea what it would look like, I'm truly a JASS noob, but this would make the whole script a million times simpler and efficient

Thanks so much in advance

well as to yew im no jass expert. but can you just set the roof to an unselectable flying unit? just get the height right and when a unit enters the region set its transparency to 100%. then just the opposite when the unit leaves :] hope i is t3h halpful

Welllll I don't really need an action specifically to hide the roof -- I'm using the Animation- Hide Doodads in Rect action for that. What I need to know is if there is a function or call in JASS that would let me fire a trigger using several Unit Enters Region events and sort through each to return EXACTLY WHICH region is being entered. I hope that is more understandable, and thanks for the thought!

Seems like you could do a boolean check to see if the region contains both the unit and the doodad, and if so then hide the doodad.

• Events
  • A unit enters a region
  • Conditions
  • Region contains X unit = true
  • Region contains X doodad = true
  • Actions
  • Hide X doodad

I think. Don't have the editor on this comp, posting from work.

You can get the entered region, but not the rect. To get the rect, you will need something like my R&R. Jass only though, I'm afraid .

Well, unless you pull off the standard GUI struct hack.

You could make a region array and loop thru each instances to find out which one contains the triggering unit. Or you can make multiple triggers...

Region array: Neater, but even less efficient than a bunch of if's.
