unit spawning and roaming help please

[war-lord]

alright so i want to make it so once a gate is destroyed certain places on the map start spawning units, the units wonder around everywhere attacking everyone they see. The only way to stop the spawning is by destroying this tower, how do i make a trigger like this?

 

[Chaosy]

well, first we want it to start when the gate dies

• start spawn
  • Events
    • Destructible - Elven Gate (Diagonal 1) 0001 <gen> dies
  • Conditions
  • Actions
    • Trigger - Turn loop

and then you turn a loop trigger
the loop trigger is how ofen the units should spawn so lets say every 30 seconds

• spawning
  • Events
    • Time - Every 30.00 seconds of game time
  • Conditions
  • Actions
    • Unit - Create 15 Footman for Neutral Hostile at loc facing Default building facing degrees

now you want them to stop spawning when a tower dies huh?

• stop spawn
  • Events
    • Unit - A unit Dies
  • Conditions
    • (Unit-type of (Triggering unit)) Equal to Guard Tower
  • Actions
    • Trigger - Turn off (loop)

Darkgrom explained everything nicely, however you can add more things like, creep leveling after some time etc etc. If you want test map can be created and uploaded for you tomorrow?

Don't make him confuse about Trigger - Turn on/off (loop)

It should be

• Trigger - Turn on spawning <gen>

• Trigger - Turn off stop spawn <gen>

He'll understand better

I might be wrong here but I'm sure someone will correct me if I am....

The loop trigger (the second one) should be turned off at the start of the game, otherwise units will start spawning as soon as the game starts. To do this in the trigger editor: right click on the loop trigger and untick the option which says "initially on". This means that the trigger will be turned off at the start of the game and it will only be switched on when the gate is destroyed.

Here you should understand how it work, just edit setup trigger and everything else will work fine...

That triggers won't work at first place,, trigger names are different, there is no defined variable loc etc etc.
It's just example what trigger should do, unfortunately example is bad, for 10 gates you will need to have 30 triggers.
In mine 2 triggers do everything, if you need it jass everything can be placed into 1 trigger.
I used same time interval and same spawn units owner, if you need this changed as well then trigger need to be split because of different even that will trigger them (in GUI).

It could be much simpler if you wanted it to be (Like Darkgrom's triggers) but that's a very comprehensive and effective system that Kobas has posted. Make sure you have a look at the variables he has set up.

 

[war-lord]

alright thank you very much but i still need to know how to make the units walk around randomly as soon as they spawn and attacking all player units/buildings and doodad gates

because you see the whole idea of this is so that once the gates are opened a dark army is unleashed on the land and to stop it you have to destroy the dark tower lol so could you give me a better example of that with like an orc unit kobas? TY for the help already though guys

Add Tornado Wander (Tornado) ability to the units.

Object editor -> Abilities tab -> CTRL + F -> wander -> Select that ability as your base ability

Next, to edit the field of the ability:

Stats - Area of Effect: This determines how big your unit will go randomly.
Stats - Cast Range: Just put it the same value as above field.
Stats - Duration - Hero/Unit: This determines how long does the unit goes to that direction before changing its direction.

Done. You have your unit to walk 'randomly' across the map, with your own settings via Object Editor.

You can also order your unit to attack its way to the main point; let's say your unit is spawned from the west and your HQ (or main position) is on the middle of the map, you can order directly to your spawned units to move-attack to the east direction

By ordering attack-move, the unit will attack anything that is enemy for him but this won't give you the feeling of 'random movement' as you can see its pattern is reaching towards easy, in orderly manner that is very much different to Wander Ability

 

[war-lord]

alright but the roaming units are computers so how do i get the computers to attack units/buildings and ALSO i need it to attack doodad gates. and also can i set them to randomly choose a place and attack it? and if so and if its a trigger can you show me howq to do it?

 

[ronojales]

a sample random-attacking trigger would be like:

• Events
  • Time - Every 2.00 seconds of game time
• Actions
  • Unit Group - Pick every Unit owned by Computer Player and do Actions
    • Unit - Order unit to Attack-Move to Location

..where Location is anywhere in a region you want the unit to attack move. the trigger simply commands the unit to attack move to that location, which changes periodically. it might not look like a real "wandering unit", but it should be able to attack any enemy unit it encounters while going to that location. also, you might want to try to make the doodad gate a unit and owned by an enemy player (though i haven't tried that) 'cause the unit will certainly only attack enemy units using this method.

btw, i haven't found any wander-attack AI system (maybe just didn't look well enough). you might to try to look at this:
