unit group attacking unit group

[turtlelink2]

i was wondering if it was posable to make a unit group attack a unit group
and they are both nutral hostile

How would that make sense? A unit may only have one target at once.

 

[Dr Super Good]

You need to make each group owned by an opposing fraction.

Then get them to attack move into each other.

They should automatically fight each other.

I'm sorry i just felt like making a super complicated way of doing what you asked

function groupattacks takes nothing returns nothing
    local group g = GetUnitsInRectAll(udg_region1)
    local group h = GetUnitsInRectAll(udg_region2)
    local unit u
    local location loc
    loop
        set u = FirstOfGroup(g)
        exitwhen u == null
        set loc = GetUnitLoc(GroupPickRandomUnit(h))
        call IssuePointOrderLocBJ(u , "attack" , loc )
        call GroupRemoveUnit(g, u)
        set loc = null
    endloop
    set g = GetUnitsInRectAll(udg_region1)
    set h = GetUnitsInRectAll(udg_region2)
    loop
        set u = FirstOfGroup(h) 
        exitwhen u == null
        set loc = GetUnitLoc(GroupPickRandomUnit(g))
        call IssuePointOrderLocBJ(u , "attack" , loc )
        call GroupRemoveUnit(g, u)
        set loc = null
    endloop
    set g = null
    set h = null
    set u = null
    call DestroyGroup(g)
    call DestroyGroup(h)
    call RemoveLocation(loc)
endfunction

Just put that into ur custom text initialization area and to call it using custom script "call groupattacks()" replace region1 and region2 with the regions you want.

This tells every unit in one region to attack a random unit in the other and vice versa and they will meet in the middle

That leaks quite a bit, and is a rather inefficient approach for Jass, so I would highly discourage it.

PS. Hundirse, try to move away from BJs.

 

[Dr Super Good]

That script leaks a tons of locations and 2 groups. It also uses not needed BJ calls that could be optimized by using their native equivalents.

Well i guess i fail...oh purple i got this super epic site you should check out

Thanks for telling me about the leaks tho, honestly, i use something similar in my map and had my beta map lag like hell. so now i know why


but to help the origenal poster

The optimum way for syncronized non random asssults that are done efficently is to loop though both groups at the same time and asign the units to target each other. If one group runs out of units before the other, then you get it to target a random unit.

Mapping the groups to an unit array would make this process even more efficent as the get random unit process would then be O(1) (direct random integer to unit slot) as apposed to blizzards slow O(n) (loops though all units in the group getting a random integer each time and setting tons of variales) method. The disadvantage of mapping the group to an unit array would be it is initially slow as it has to loop through the group to asign each unit a slot (probably faster than one of blizzards random unit from group calls lol), but after that it would be faster as you can loop through all units simply by using an integer comparison and opperation.
