pick every unit in front of attacker?

[polo2005]

how should this look like?
i want to detect all units in front of my unit, but i'm pretty bad about facing

z x
O> x
z x

O= my unit
> facing
x= enemies that should be detected
z= enemies that shouldn't be detected

Actions
    Custom script:   set bj_wantDestroyGroup=true
    Unit Group - Pick every unit in (Units in (Playable map area)) and do (Actions)
        Loop - Actions
            If (All Conditions are True) then do (Then Actions) else do (Else Actions)
                If - Conditions [B][U]how should the condition things look like?[/U][/B]
                Then - Actions
                Else - Actions

Something like that. Untested though. Alter the 45 degree to suit your detection width.

ty, but do i need to set Real_Var?

> do i need to set Real_Var?

Yes. Because sometimes the unit facing angle value can get confusing. -350 degree is similar to 10 degree. You have to convert it to positive. (Not sure about the Angle of Position of X to Position of Y, though, try testing it yourself by setting the value of the angle to know whether it's negative or positive)

 

[polo2005]

hmm kk. ty for your help =)

edit:
btw what does do?

        If (All Conditions are True) then do (Then Actions) else do (Else Actions)
            If - Conditions
                Real_Var Less than 0.00
            Then - Actions
                Set Real_Var = (Real_Var + 360.00)
            Else - Action

Edit 2: doesn't work

skill facing problem

why doesn't this work like it should?
it damage a bit allaround the caster (not at same plase nor right plase there it should be)

why?

not. this leaks

You didn't set the Variable Real_Var...

 

[polo2005]

You didn't set the Variable Real_Var...

what do you mean? oO

        Set Real_Var = (Facing of (Triggering unit))

 

[AceHart]

"Facing of unit" is between 0 and 360, whereas "angle between" is between -180 and +180...

srry didn't get it :banghead:
i'm from sweden and my english isn't my strongest side...

could you try to exsplain it in a easier way? oO

You might need Real_Var_2. What Ace meant (which was the same thing that I explained in Post#4) was that the angle values can return as negative values. Sometimes, the trigger cannot differentiate this (or instead, it's made to be this way). For example, if you compare facing angle and angle between points, the presence of negative numbers will mess up the number comparison at the condition part (because you +45 and -45). So, whenever possible, if there's a negative angle, try to convert it to positive.

As I said, -350 degree is also similar to 10 degree. -180 degree is similar to 180 degree. -28 degree is similar to 332 degree. So, the bolded part of the trigger takes care of the conversion of negative to positive value.

omfg its working hahahahaha lol zomg.... ty =)
