Region and unit spawn

[Bendistocratic]

Hi! I need some help with the triggers. How do you make units spawn multiple times in a region (A) after a unit has entered a region (B)?

 

[twistedfate08]

Make a 2 regions in the map..
Events:
Unit -A Unit Enters Region 1<gen>
Conditions:
Actions:
Unit - Create 10 Footmans for Player at Region 2<gen> facing default building facing degrees.

I dont know.. but try it

Sure do! If you mean the GUI editor in warcraft 3, you'd want to have the event:

Unit enters region x

Condition:

Unit equals (unit of your choosing)

or leave the condition blank if you want any unit type to trigger this function

Then in the actions you can have:

Spawn x units at centre of region y

-------------------------------------------

hope this helps!

By means of "multiple times", is it like spawn in a bulk or one by one ?

if one by one the easiest way is local variable and a wait. first set units in array that u want to spawn if u want lvls to get higher as the waves are spawned.

then do this.
if a unit enters region 2 this will spawn a unit[1] the first time unit enters region. when a new unit enters the region it will spawn unit[2] and so on. if u dont want this to happen use the second trigger.

• wave spawning
  • Events
    • Unit - A unit enters Region 2 <gen>
  • Conditions
  • Actions
    • Custom script: local unit udg_tempUnit = GetTriggerUnit()
    • Custom script: local integer udg_tempInt = 1
    • Custom script: local integer udg_tempInt2 = 1
    • Custom script: local location udg_tempPoint = Location(GetRectCenterX( gg_rct_Region_1), GetRectCenterY( gg_rct_Region_1))
    • Custom script: local integer udg_tempInt3
    • Set waveCounter = (waveCounter + 1)
    • Custom script: set udg_tempInt3 = udg_waveCounter
    • For each (Integer tempInt) from 1 to tempInt2, do (Actions)
      • Loop - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • (Region 2 <gen> contains tempUnit) Equal to True
          • Then - Actions
            • Unit - Create 1 unitTypeArray[tempInt3] for Player 1 (Red) at tempPoint facing Default building facing degrees
            • Set tempInt2 = (tempInt2 + 1)
          • Else - Actions
        • Wait 2.00 seconds
    • Custom script: set udg_tempUnit = null
    • Custom script: call RemoveLocation( udg_tempPoint)
    • Custom script: set udg_tempPoint = null

second trigger.
this will spawn the same unit whenever a unit is in region 2

• wave spawning
  • Events
    • Unit - A unit enters Region 2 <gen>
  • Conditions
  • Actions
    • Custom script: local unit udg_tempUnit = GetTriggerUnit()
    • Custom script: local integer udg_tempInt = 1
    • Custom script: local integer udg_tempInt2 = 1
    • Custom script: local location udg_tempPoint = Location(GetRectCenterX( gg_rct_Region_1), GetRectCenterY( gg_rct_Region_1))
    • For each (Integer tempInt) from 1 to tempInt2, do (Actions)
      • Loop - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • (Region 2 <gen> contains tempUnit) Equal to True
          • Then - Actions
            • Unit - Create 1 urUnitType for Player 1 (Red) at tempPoint facing Default building facing degrees
            • Set tempInt2 = (tempInt2 + 1)
          • Else - Actions
        • Wait 2.00 seconds
    • Custom script: set udg_tempUnit = null
    • Custom script: call RemoveLocation( udg_tempPoint)
    • Custom script: set udg_tempPoint = null

Sorry if I didn't make it more explicit. It is something like a mission where 1 of your unit manage to make it to that region. Then from there onwards, units will keep spawning to help you to defeat the evil people. It does not need to have a unit always stationed at that area.

I'm not very sure how to do it, but I split this into 2 parts, where:

Trigger 1
Event: Unit enters region X
Condition: (Owner of (Triggering unit)) Equal to Player 1 (Red)
Action: Turn Trigger 2 on

Trigger 2
Event: Every 5 seconds of game time
Condition: NIL
Action: Spawn 5 footman at region Y

Is this right? Nothing spawns even when a unit enters region X. Or I can just combine both triggers?

 

[deathismyfriend]

those triggers should be fine.

 

[Bendistocratic]

Thanks a lot guys!

 

[deathismyfriend]

just make sure to clean ur leaks.

You should used differed spawning to prevent the engine having to drop frames. Spawn like 1-2 unit at a time and never at the same space. Displacing units at the same space is surprisingly costly for the game engine.
