I'm pretty much new to Starcraft mapediting, but I have quite a lot of experience in mapping for Warcraft 3, mind you, it's not the same.
I was wondering how to make a trigger that spawns a certain unit for a certain player at specified intervals of time as long as the command center/hive/nexus is still functional.

Also useful would be if someone gave me a link to a tutorial that lists various useful triggers to use and how to set them up so it works.
Or a whole site that has a bunch of tutorials. (Tutorials on this site just gives me "Omg. No permission." <.<)

Players :
1,2,3,4,5,6,7,8
Condition :
Current Player bring at most 1 Zerg Hive to Anywhere
Action :
Create *desired number of units* *desired unit* at *desired location*
Wait *desired time* miliseconds
Preserve Trigger

Players :
1,2,3,4,5,6,7,8
Condition :
Current Player bring at most 1 Terran Command Center to Anywhere
Action :
Create *desired number of units* *desired unit* at *desired location*
Wait *desired time* miliseconds
Preserve Trigger

Players :
1,2,3,4,5,6,7,8
Condition :
Current Player bring at most 1 Protoss Nexus to Anywhere
Action :
Create *desired number of units* *desired unit* at *desired location*
Wait *desired time* miliseconds
Preserve Trigger

Example of action trigger:
Action :
Create 1 Terran Marine at Spawn
Wait 5000 miliseconds
Preserve Trigger

Will try, thank you.

The above would work if you use no other wait somewhere.

But as a general rule for sc mapediting I tell you not to use waits at all.
They will cause wait blocks (prevents triggers from firing) and/or throw off timing as your maps becomes more complex (when executing a wait action other triggers will run again).

Use a death counter system instead. Death counters (DCs) can be used for many more things, so its wise you learn them ASAP.
The basic idea is you take a unit you dont use in your map and modify (set, add, subtract) the death counts (sc counts how often a certain type of unit has been killed) for this unit. This can be done by triggers AND actual kills ingame, but because you dont use the unit it cant be killed, so you have full control over the DC. Simply count up every trigger loop until you reach the desired delay. Then you spawn the units and reset your counter to 0.

Take a unit lets say neutral - critters - kakaru and rename it to "Spawn Counter"
Create a location over every command center and rename them to "Spawn Loc 1-6"
So lets say you want to spawn untis every 10s (1 trigger loop take 2s of sc game time, an about 1,5s real time on speed 7)
Here are sample triggers how you can do it:

Trigger 1: Counter
Human Players (e.g. P1-6)
Conditions:
Always
Actions:
Add 1 for death counts of "Spawn Counter" for current player
preserve trigger

Trigger 2: Spawn / Reset
Player 1
Conditions:
Current player brings at least 1 Command Center to "Spawn Loc 1"
Current player has suffered at least 5 deaths of "Spawn Counter"
Actions:
Create 1 unit for current player at "Spawn Loc 1"
Set to 0 for death counts of "Spawn Counter" for current player
preserve trigger

Trigger 3: Spawn / Reset
Player 2
Conditions:
Current player brings at least 1 Command Center to "Spawn Loc 2"
Current player has suffered at least 5 deaths of "Spawn Counter"
Actions:
Create 1 unit for current player at "Spawn Loc 2"
Set to 0 for death counts of "Spawn Counter" for current player
preserve trigger

...
For all players.

Then you are on the safe side.

Also, asaguda, go to www.maplantis.org if you want tutorials.

Yeah, I don't really get that with the DC system, but thanks anyways. Will try using wait anyways and see what happens. If it fucks up completely, I'll come back and demand a more detailed description of DCs. Or look for one, first.

Ah. I get it now.
The counter trigger makes the game think you have killed the critter, and when it reaches 5 the death counter for the critter resets and spawns a unit, and as you said the counter trigger would loop once about every 2 seconds.
Hehe, thanks alot!

Here is some great help like you ask for http://www.maplantis.org/index.php?sid=2945864bc9a306e47c5e29fa1360b098;pg=wiki

YAY lets advertise maplantis everywhere! On second thought lets not.

Here are some example maps of things that are commonly used.

Thanks. I find it tiresome to make triggers for each player separately though, is there any editor that can batch edit the same type of attribute in the same type of trigger? Or maybe a trigger exclusive program? ><
*Googles it too.*

Use scmdraft 2 0.8 there you can copy and paste if you use trigger editor (not classic map trigs).
Then write a simple c++ code that writes the triggers for you. Or make copy and paste manually if its only a few times with similar code.

Or with trigedit use replace in notepad or my trigger duplicator that duplicates text.

Easiest way to copy triggers for multiple players is just to select the multiple players and use Current Player all the time.. but of course this doesn't work when locations are involved. SO, just make it for one player, open up trigedit, copy the section used into Wordpad, and use the Replace All function accordingly. Use Wordpad over Notepad, it does the replace all function much quicker.

Another tutorial that tends to help people with death counts.

Using current player wouldn't work for what you want unless you want to have them all spawn at the same spot, but using current player reduces the amount of actions you have to edit for each player when you copy the triggers.

Also my duplicator has a replace function, faster than notepad and also capable of multiline replace.

where can we get a hold of that duplicator?

I wish you people would stop advertising maplantis now, kthnx.

Sorry, that the unprotectors are on the same page as the requested file. Not my problem.

Maplantis is currently the place with the most complete UMS reference and tutorial wiki, not to mention the file/map db and modding resources. How about you stop complaining about people linking to completely relevant resources?
