NOT a backstab spell

[streetpunk]

Hello everyone, I would like to ask if anyone knows how can I detect if a unit is behind another, BUT I don't wanna know the difference between their facing angles, I wanna know if unit1 is in the "region" behind unit2, regardless of their facing angles.

Regardless of their facing angles ? So if unit1 is facing unit2 then what, doesn't that brake the definition of behind ?

IsUnitBehindUnitRegardlessOfAngles(unit1, unit2)
{
return true;
}

You could calculate the distances to the center of this "region" if you mean that.

• WhoLeads
  • Ereignisse
  • Bedingungen
  • Aktionen
    • Set LocCenter = (Center of (Playable map area))
    • Set Loc[1] = (Position of Unit[1])
    • Set Loc[2] = (Position of Unit[2])
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Condtions
        • (Distance between LocCenter and Loc[1]) greater as (Distance between LocCenter and Loc[2])
      • Then - Actions
        • -------- Unit 2 is behind --------
      • Else - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • (Distance between LocCenter and Loc[1]) Unequal (Distance between LocCenter and Loc[2])
          • Then - Actions
            • -------- Unit 1 is behind --------
          • Else - Actions
            • -------- Even --------

Edit: Hmm found a Problem works only if they walk to the region if the walk away you need to switch the first two results.

a unit doesn't need to be facing the back of another to be behind it
Footman is behind Rifleman regardless of his facing angle
EDIT: Footman is behind RIFLEMAN'S BACK, regardles of the footman's facing angle.

Depends from where you look at the two units behind is here a relativ thing.
You need a source Point from which you look at them to say who is behind who.

 

[streetpunk]

Let me correct this: Footman is behind RIFLEMAN'S BACK, regardles of the footman's facing angle.

If that's what you are looking for, somekind of stealh mechanic.

function IsUnitBehind takes unit main, unit u returns boolean
    local real xInFront = GetUnitX(main) + 1 * Cos(bj_DEGTORAD *  GetUnitFacing(main))
    local real yInFront = GetUnitY(main) + 1 * Sin(bj_DEGTORAD *  GetUnitFacing(main))
    local real Angle1 = bj_RADTODEG * Atan2(GetUnitY(main) - yInFront, GetUnitX(main) - xInFront)
    local real Angle2 = bj_RADTODEG * Atan2(GetUnitY(u) - yInFront, GetUnitX(u) - xInFront)
    local real Angle
    // Make Angel1 +
    if   Angle1 < 0.00  then
        set Angle1 =  Angle1 + 360.00
    else
    endif
    // Make Angel2 +
    if   Angle2 < 0.00  then
        set Angle2 =  Angle2 + 360.00
    else
    endif
    // Simplfy Calculation at 0° line if needed
    if  ( Angle2 >= 270.00 and  Angle1 < 90.00 ) then
        set Angle1 =  360.00 + Angle1
    else
        if ( Angle1 >= 270.00 and  Angle2 < 90.00) then
            set Angle2 =  360.00 + Angle2
        else
        endif
    endif
    set Angle =  Angle1 - Angle2
//    call DisplayTimedTextToForce( GetPlayersAll(), 5.00, R2S(Angle1) + " / " +R2S(Angle2) + "->"+R2S(Angle) )
    return (  Angle >= -80.00 and Angle <= 80.00 )
