Remove Random Unit from Group/ Add Unit to another Group

[asdfADRiAN]

Ive made a dialog system for a game mode. Basically at the beginning all unused players are removed from the game. Those who are in "Is Playing" slot status condition, will be added to the unit group "Team_Human" which is basically the human team. Then when selecting the corresponding dialog button selecting One, Two, or Three player zombies would randomy remove those player's Units from the Unit Group "Team_Human" and add them to the unit group "Team_Zombie" also creating a zombie unit for those selected.

I have 3 different variations of this trigger that will randomly select a player's unit, remove their "Human" unit and then create a zombie unit.

Heres the current trigger, theres 2 (first one is when Host selects 1 Zombie, and second trigger is when host selects 2 zombies). I didnt include the third trigger because its pretty much the same except with the creation of 3 units.

I know I didnt use the variable there properly, and it does nothing, but I just left it there so you can get a general idea of what im trying to accomplish.

EDIT: I also have this trigger that would create randomly a zombie at a random point position of a human unit.

• Unit - Create 1 Zombie (Hooked Flesh) for Neutral Hostile at (Random point in (Region centered at (Position of (Random unit from team_human)) with size (10.00, 10.00))) facing (Random angle) degrees

But this will also create zombies in places where zombies cant even get out of. I know the "Playable" map function will create units where that can move around (this excludes small tight places like trees where a unit cant get out of) but I dont know how to incorporate it to my trigger so it would be something like:

Unit - Create 1 Zombie (Hooked Flesh) for Neutral Hostile at (Random point in (Region centered at (Playable Map Position of (Random unit from team_human)) with size (10.00, 10.00))) facing (Random angle) degrees

The problem here is that the zombie is being placed in a playable map area. The game doesn't really know whether or not you can "escape" an area that you are placed - you're going to have to note these positions yourself and avoid them manually. I suppose you could check the pathability at points around the placed unit and see whether it is "trapped" or not but that isn't guaranteed to work 100% of the time.

 

[asdfADRiAN]

Oh, I assumed Playable Map Area took into account the pathings whereas Entire Map included every aspect of the map.
Anyways how do you propose you would trigger it? Is that the only possible way, or are there other alternatives I can take?

 

[asdfADRiAN]

Never mind, well I got it working now.

How would I set alliances of players using unit groups? Right now I have units organized in unit groups because the setup for unit groups were much more easier and I didnt know how to do it through Player Groups.

Can anyone help me on this :|?

So what did you end up doing to solve the problem?

You could use the owning player of the unit to determine the associated player - this is a fairly simple approach, though using player groups in conjunction with unit groups isn't all that complex either.

 

[asdfADRiAN]

With the implementation of the player groups in conjunction with the unit groups, I was able to successfully create the dialog trigger using variables and working my way around it.

Anyways.. I still cant seem to get that spawn trigger correctly. Also, the zombies are stupid, AI is terrible. They just run into walls and stay there.. Theres openings and doorways but only 1/4 of the mobs walk into the houses.

The other 3/4 just stand next to the other side of the wall trying to get the survivors within..

 

[Berb]

So the AI is the problem?

 

[asdfADRiAN]

Yeahh, which i have no idea how to fix. My walls are custom model walls as destructables with pathings.

 

[Berb]

If you only create one zombie will it still move to the wall instead of going to an "entrance"?

 

[asdfADRiAN]

Yeah just right into the wall. I only spawn them one at a time. if spawned inside the house then it will manuever its way through... Very slowly though, bit by bit

which i guess slowly is fine since its a zombie but right into the wall ruins the gameplay... just terrible

 

[Berb]

What happens if you make the walls pathing "thicker"?

 

[asdfADRiAN]

Cant remember the exact size but its the size of wc3's stone wall models, only the 90 degree oriented ones though (horizontal and vertical). I think 3x1?

So if not this size then by how much would you suggest? Also why a bigger pathing texture, does wc's AI not detect such sizes?

Also when created a zombie, I would store the created unit in a variable and order it to attack a random unit in the unit group (Human_Team). Perhaps thr issue orders cayse the problem? Is their a more efficient way of ordering units to attack another?

 

[Berb]

I would try issuing an "attack move" order rather than an "attack" order; it will cause heroes that could possibly come in the path of the zombie to be attacked instead of the zombie simply trying to bypass it; it also may help with the pathing calculations.
