Facing units

[BloodDrunk]

how can i make the facing of two units like face to face?

 

[Nestharus]

call SetUnitFacing(unit1, GetUnitFacing(unit2) + 180)

given that one is facing the other

if one isn't facing the other, set angle = Atan2(GetUnitY(unit2) - GetUnitY(unit1), GetUnitX(unit2) - GetUnitX(unit1))*180/bj_PI

then
call SetUnitFacing(unit2, angle)

then do the +180 for unit1

note
I may have them backwards for the angle, so if that's the case, then swap unit1 and unit2 in the SetUnitFacing

edit
doing 3D?

yeah, i also though i needed to put tht +180. Lemme see how it works

not working :O

this:

• (Facing of IB_TrigUnit) Equal to ((Facing of (Picked unit)) + 180.00)

i need to be like when he faces the picked unit

 

[Nestharus]

gave you the code for making 2 units face each other

 

[BloodDrunk]

But i dont want to make them face me. I want the trigger to runs when someone faces me or i face them, not that i force them to face me

 

[Nestharus]

ohhhh, I thought you meant like 2 units facing each other, not 1 unit looking at another unit

I gave you the line for the 1 unit thing, the Atan2 one to get the angle : )

 

[Maker]

Facings are not accurate, if you order a unit to face 90 angle, it might face an angle of 89,45 in the end.

Trigger

• BS3 Copy
  • Events
    • Unit - A unit Is attacked
  • Conditions
  • Actions
    • Set u1 = (Attacking unit)
    • Set u2 = (Attacked unit)
    • Set p1 = (Position of u1)
    • Set p2 = (Position of u2)
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • // Use one or the other condition
        • (Cos(((Angle from p1 to p2) - (Facing of u1)))) Less than 0.00
        • (Acos((Cos(((Angle from p1 to p2) - (Facing of u1)))))) Greater than 90.00
      • Then - Actions
        • Game - Display to Player Group - Player 1 (Red) the text: Not facing
      • Else - Actions
        • Game - Display to Player Group - Player 1 (Red) the text: Facing
    • Custom script: call RemoveLocation(udg_p1)
    • Custom script: call RemoveLocation(udg_p2)

 

[BloodDrunk]

wht does that acos does when you have cos inside it already?

 

[Maker]

Basically it converts the angle range from -1...1 to -180...180.
