Alright, so I started working on my map again and it's going to be a Helms Deep type of map. My problem with this are the triggers because SC2 triggers are so much more complicated than SC1....

1.
When I try to run the trigger (in the picture below), it is supposed to first check if there are 0 to 75 any units in Region 001 (the entire map), (if trigger)
if true, create these units specified below at certain locations and run trigger again waiting for the current one to finish
if false, run the trigger again waiting for the current one to finish

Problem is the if trigger isn't working correctly. Can anyone help?

2.
Also. How do you do the sc1 trigger of "Bring any unit to location" condition?

3.
How would I make an area of buildings invincible without triggers and if I can't do that how would i do it with triggers?



Attachments:

1. Use a "Periodic Event" Event. the "Map Init" only runs once: at map's first second.
2. You're searching for "Unit Matching Conditions" as the Unit.
3. Via triggers, use "Set Invincibility" (or is it "Set State" or "Set Invulnerability"). Via Data Editor, there's an "Invincible" (or "Invulnerable"?) flag you can check in the specific building's Unit tab. However, this flag will apply to all buildings on the map. Via triggers, I think you can also use the "Add Behavior" action to add the Behavior "Invincible" (or...) to the buildings.

1. This type of map will suck on SC2 because SC2 has a graphics engine, as opposed to SC1 which had Microsoft Paint. People will be forced to run your map on the lowest graphic settings, or be leave as soon as their frame-rate drops to unacceptable levels.

But, to answer your questions:
1. Firstly, your If statement. You're saying IF 0 is less than or equal to the number of units 'attached to the region'.. and well, okay.. Sorry I give up, I'll let someone else do this, someone with more patience.

In the mean time, go read a tutorial.

Nib this map is waaaaaaaaaaaaaaaaaaay to hard for u to make... U will come back and ask for 10000 stuff if u cant even figure those out.. Read guides, look at onetwo howto's on youtube and try to learn more basic stuff

It won't work that way because the trigger runs over and over and over without wait/sleep. It's an hidden infinite loop. Starcraft should throw the error with "nested ..." something.
solutions:
-> Check if there are <= 75 guys in the area periodically like payne said it.
-> OR check that, whenever a unit dies OR leaves the region

Btw, you can have actions below the whole "if"-thing that will be executed after the "if" or "else". Having the same action for "if" and "else" is redundant and can be shortened with 1 action after the "if"-thing.


The unit attached condition won't count the units inside the region (I THINK... have to tinker a bit with that to gain more knowledge about regions and unit attachments).


@payne
his main mistake is the trigger call which causes an infinite loop, not when the whole loop is initiated which will cause many many units spawned at map start and/or causing an error.

@2
payne's post!

@3
without triggers -> data editor -> behavior with an periodic effect that searches buildings in an area around the unit and which will add an invincibility behavior onto the unit which will have a limited lifetime and disables the invincibility, if the time expires.
I would start copying the mothership's cloak ability and change the effect. It's doing what you want with a wrong unit filter and wrong effects.

You learn nothing, if you do nothing. Better start and learn to do things one by one even if you might cancel the map later on.
Every working system is a success and the gained knowledge will help him later on.

haha. thanks for being supportive. sc1 is so much easier than sc2....

1. What I'm currently wondering is why this would be an infinite loop. The logic i was looking for was, "If player 4 commands less than 75 units, then the player 4 respawns his 200ish units, which should check not at a certain interval, but continuously. Oh wait. I accidentally put player 1 instead of player 4... Lol. If i changed that to player 4 instead of player 1, would this be fine as a trigger?

2. thanks for your help payne

3. Also, going back to the invincibility question, I was going to have it where a set of supply depots start out invincible (thus the gates from sc1) and by killing a certain building (hinge) it would deactivate those supply depots' invincibility. Data modding sounds like a great idea but the radius would be very inflexible, and I don't want these supply depots to stay invincible like payne suggested by setting them default. Also, Via Triggers, i tried that but that would mean i would have to create about 30 supply depots and about 200 hinge defenses that turned invincibility off and on, via triggers. So I guess the question I wanted to ask was, How would i set a group of certain units in a specific location invincible and be able to toggle it off later? Or would data modding be the only option?

The code runs over and over and never comes to the point where the system can do other stuff. The problem is that you are starting the trigger at the end of your trigger every time.

There are other events that are suited for your problem like the "unit leaves region" and the "unit dies". Both will start the trigger and in that trigger you should check the amount of alive units within a region. And they are more efficient than a periodic checks because periodic checks cause periodic lags.

I would add all the units with filters (e.g.: alive, building) to a unit group (global variable, variable in the trigger list), check every unit's type (e.g.: being a supply depot) and activate the invincibility. Later on, I would run through the unit group again and disable the invincibility.
