I tried to create backstab spell in GUI.
Look at triggers. When i cast this spelll it isn't backstab. It's Frontstab. How to fix it?

lol wtf?
this could be better

• Backstab
  • Events
    • Unit - A unit Is attacked
  • Conditions
    • (Level of Backstab for (Attacking unit)) Greater than 0
  • Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • ((Attacked unit) belongs to an enemy of (Owner of (Attacking unit))) Equal to True
      • Then - Actions
        • Set Caster[1] = (Attacking unit)
        • Set Target[1] = (Attacked unit)
        • Set Point[1] = (Position of Caster[1])
        • Set Point[2] = (Position of Target[1])
        • Set Real[1] = (Angle from Point[1] to Point[2])
        • Set Real[2] = (Facing of (Attacked unit))
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • And - All (Conditions) are true
              • Conditions
                • Real[1] Greater than or equal to (Real[2] - 45.00)
                • Real[1] Less than or equal to (Real[2] + 45.00)
          • Then - Actions
            • Special Effect - Create a special effect attached to the overhead of Target[1] using Abilities\Spells\Other\Stampede\StampedeMissileDeath.mdl
            • Special Effect - Destroy (Last created special effect)
            • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
              • If - Conditions
                • (Caster[1] is an illusion) Equal to True
              • Then - Actions
                • Unit - Cause Caster[1] to damage Target[1], dealing (0.33 x ((Real((Level of Backstab for Caster[1]))) x (0.50 x (Real((Agility of Caster[1] (Include bonuses))))))) damage of attack type Hero and damage type Normal
              • Else - Actions
                • Unit - Cause Caster[1] to damage Target[1], dealing ((Real((Level of Backstab for Caster[1]))) x (0.50 x (Real((Agility of Caster[1] (Include bonuses)))))) damage of attack type Hero and damage type Normal
          • Else - Actions
        • Custom script: call RemoveLocation( udg_Point[1] )
        • Custom script: call RemoveLocation( udg_Point[2] )
      • Else - Actions

a simple backstab that deals 0.5x level of backstab for attacker, illusions deal 33% dmg

^Does that actually wowrk correctly? Angle from x to y ranges from -180 to 180, facing of unit from 0 to 360.

Here's an alternative that does work:

Trig

• Attack GUI Copy
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • Ability being cast equal to...
  • Actions
    • -------- -------------------------------------------------- --------
    • -------- Set unit variables --------
    • -------- -------------------------------------------------- --------
    • Set u1 = (Triggering unit)
    • Set u2 = (Target unit of ability being cast)
    • -------- -------------------------------------------------- --------
    • -------- Set location variables --------
    • -------- -------------------------------------------------- --------
    • Set p1 = (Position of u1)
    • Set p2 = (Position of u2)
    • -------- -------------------------------------------------- --------
    • -------- Get angle from "caster" to target --------
    • -------- -------------------------------------------------- --------
    • Set r1 = (Angle from p1 to p2)
    • -------- -------------------------------------------------- --------
    • -------- Get caster facing --------
    • -------- -------------------------------------------------- --------
    • Set r2 = (Facing of u2)
    • -------- -------------------------------------------------- --------
    • -------- Get angle difference --------
    • -------- -------------------------------------------------- --------
    • Set r3 = (Acos((Cos((r1 - r2)))))
    • -------- -------------------------------------------------- --------
    • -------- Clear leaks --------
    • -------- -------------------------------------------------- --------
    • Custom script: call RemoveLocation(udg_p1)
    • Custom script: call RemoveLocation(udg_p2)
    • -------- -------------------------------------------------- --------
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • r3 Less than 90.00 // adjust this value to alter the "width" of backstab
      • Then - Actions
        • Game - Display to Player Group - Player 1 (Red) the text: Backstab!
      • Else - Actions

 

[Marsal]

lol? passive skills can use the "Starts the effect of the ability" ?

 

[kawas11]

this isn't passive skill
Thanks a lot for help

 

[Marsal]

heh I thought ~.~

 

[doom_sheep]

when i do this stuff i never bother with cosinis or whatever

• Actions
  • If, Then, Else:
    • If - Conditions
      • distance between ((Temppoint offset by 100 towards (Facing of unit1)) and (Temppoint offset by 100 towards (Facing of unit2))) less than X
    • then - Actions
      • derp!

 

[wolfman]

uhh, why would you do Arccos of cos? lol the arccos and cos just cancel each other out...
Just do a1 = facing of caster, a2 = facing of target
if a2 > a1 - 45 and a2 < a1 + 45 then backstab. This would backstab if the target was facing away from the caster within a 45 degree margin.
kinda like this:

\.................../
..\.............../
....\.........../
......\......./
........\.../
......target
......caster

the slashes show the area that the target could be facing for the backstab to work. Although that picture shows about a 20 degree margin on each side
