[Trigger] Checking Region

[Jay the Editor]

How do I check whether the region enters by a unit?

Example

• Group Changing
  • Events
    • Unit - A unit enters Point1 <gen>
    • Unit - A unit enters Point2 <gen>
    • Unit - A unit enters Point3 <gen>
    • Unit - A unit enters Point4 <gen>
  • Conditions
    • <<some condition>>
  • Actions

So, in this action, I want to check the region entered by the unit. If region enter by the unit is Point1, then I add this unit into unit group 1 whereby if the unit enter Point2, I add this unit into unit group 2 and so on.
I found only this condition: "All units are in region..." but don't have the condition when a single unit of the particular group enters a region.

You may want to split your trigger into multiple. One per point. That way you know the unit is in that particular region.

 

[rulerofiron99]

Put all the regions in an array, and check using the boolean - Unit is in region.

To Ralle: Thanks but that way will make the code inefficient
To rulerofiron99: Thanks haha.. overlook that condition. >.< lol .. Sorry but couldn't add onto your reputation. it pops out something duno say what must spread the reputation before add to you @@

The solution ruleofiron99 gave you is a good one, but it can fail at times.

When "a unit enters region" event triggers, "unit is in region" can still return false.

Here's a system that sets the triggering region into a variable, just in case you need it:

Triggers

• Init Copy
  • Events
    • Map initialization
  • Conditions
  • Actions
    • Custom script: local region r
    • -------- ---------------------------------------------- --------
    • Hashtable - Create a hashtable
    • Set RectHash = (Last created hashtable)
    • -------- ---------------------------------------------- --------
    • Set Trig = Enter Copy <gen>
    • -------- ---------------------------------------------- --------
    • Set RectEnter[0] = Region 003 <gen>
    • Set RectEnter[1] = Region 003 Copy <gen>
    • Set RectEnter[2] = Region 003 Copy 2 <gen>
    • -------- ---------------------------------------------- --------
    • For each (Integer A) from 0 to 2, do (Actions)
      • Loop - Actions
        • Custom script: set r = CreateRegion()
        • Custom script: call RegionAddRect(r, udg_RectEnter[bj_forLoopAIndex])
        • Custom script: call TriggerRegisterEnterRegion(udg_Trig, r, null)
        • Custom script: call SaveRectHandle(udg_RectHash , GetHandleId(r), 0, udg_RectEnter[bj_forLoopAIndex] )
    • -------- ---------------------------------------------- --------
    • Custom script: set r = null

• Enter Copy
  • Events
  • Conditions
  • Actions
    • Custom script: set udg_Rect = LoadRectHandle(udg_RectHash , GetHandleId(GetTriggeringRegion()) , 0)
    • Special Effect - Create a special effect at (Center of Rect) using Abilities\Spells\Undead\AnimateDead\AnimateDeadTarget.mdl
    • Special Effect - Destroy (Last created special effect)

oo.. I was using "A unit enters ..." event. So, in your triggers given. The "Enter copy" is the trigger that I add my actions there? No events needed?

Edit: I got it now. Thanks, sir.
