Hi, so basically, when a unit enters a specific region, it spawns units at another region every 15 seconds. I tried to make these as two separate triggers, so have one trigger create units every 15 seconds, and the other one call this trigger when a unit enters the area. But when you call a trigger, it ignores its event, so in my case it only spawns the units once. Any ideas?

    Events
        Timer - Every 15 seconds of Game Time
Condition
 (Unit type of (Unit 1 from (Any units in DesiredRegion owned by player X matching with at most Any Amount)))==DesiredUnit

Action
Create Unit at DesiredPoint
Turn current trigger on

Turn Trigger Off/On

Riley, even when you turn the trigger on again, the unit wouldn't be considered reentering the region, as its already inside it. He wants a contnious spawn so there isn't a need to set patrol on the units to keep spawninng them

This is another way I was using earlier, its longer, but simpler

Not that I don't appreciate needless complexity but how about:

Unit Enters Region Turn Spawn Stuff On

Unit Leaves Region Turn Spawn Stuff Off

Spawn Stuff Every 15 seconds Create unit

Nothing wrong with your rube goldberg machine, though.

@RileyStarcraft:

actually thats eaxctly what i posted right above that

Just with values filled in

Actually, its got an extra population check in it, but one extra condition isnt what one calls a rube goldberg machine ;)

Also notice I put in another one two posts above that that only utilizes one trigger, but has fallible mechanisms (I.E. if theres a beacon or other unit in the region)

Thanks guys, the trigger on/off was the key.

@Feldeat: Go

You're right I was thrown off by the fact that you put Turn Current Trigger On at the end of every trigger and thought you were doing something else. You realize that there is absolutely no reason for doing that?

@RileyStarcraft:

Then whyde you suggest it earlier?
And no, I didn't realize its not neccasary. I'm pretty new to SC2 editor, and coming from AoE2 editor i'v got some bad habits =)

So a trigger event will continously set off?

Overkill guys, only need one trigger.

Spawn Marines
    Events
        Unit - Any Unit Enters Region A
    Local Variables
        ------- local copies since all Event* functions are prone to race conditions.
        Unit = (Triggering unit) <Unit>
        Region = (Triggering region) <Region>
    Conditions
    Actions
        General - While (Conditions) are true, do (Actions)
            Conditions
                (Unit is in Region A) == true
            Actions
                Unit - Create 1 Marine for player (Owner of Unit) at (Center of Region) facing 270.0 degrees (No Options)
                General - Wait 1.0 Game Time seconds

The way i see it is that, if you want to link one trigger to another, and you want it to consider its event, than you need to turn the trigger on. and that's what i did. I had one trigger activate once a unit enters the region, and then in the actions i had it run the another trigger, which creates units followed by turn current trigger on.

edit: oh also, i had question relating to regions. Is there a way to link multiple regions, for example, in my case if a unit enters lets say any one of four regions, then it should start spawning units.

edit: @caspersc: thanks for the alternate solution

@insom89: Go

Use Add Region to Region and create a region with the four regions you need. Use that region (can be a dummie region) for the Event.

@fr0d0b0ls0n: Go

oh okay, will it be one region or can i still distinguish between the smaller ones?

@insom89: Go

One region, but the other regions still exist, so you can check them. You need to create a dummie blank region to add the other 4. Don't add the regions to one of them.

Dummie Region: Use Add Region to Region to add region 1, 2, 3, and 4.

Event: unit enters Dummie Region.

Then you can do some If Activator Unit in Region 1, 2, 3 or 4.

i c thanks!
