[Spell] rotating objects around a unit causes minor problem

[Nordmar]

Hi, I am trying to rotate objects around the unit in the center and move them closer and closer towards it. This works fine except for the very first spawned object and I don't understand why. The first object seems to spawn not with an offset of 600 but more? i really dont know.

Any help is appreciated. Thanks

Whenever you're about to create those dummies, you're doing this:

• Unit - Create 1 dummy_evilSorcerer_shots for Player 11 (Dark Green) at (z_leakRemove_point offset by 600.00 towards (270.00 + ((Real((Integer A))) x 40.00)) degrees) facing ((Angle from (Position of (Last created unit)) to (Position of Evil Sorcerer 0059 <gen>)) + 90.00) degrees

"Angle from (Position of (Last created unit)) to (Position of Evil Sorcerer 0059 <gen>)"

Last created unit might be pointing to another unit. It can't refer to the dummy unit, because it's not created yet. Also, the Polar Projection creates another point/location, and you're not storing it in a variable. It's leaking for now.

You could do this in order to fix it:

• Actions
  • Animation - Play Evil Sorcerer 0059 <gen>'s stand channel animation
  • Sound - Play CharmTarget1 <gen>
  • Set z_leakRemove_point = (Position of Evil Sorcerer 0059 <gen>)
  • For each (Integer A) from 0 to 8, do (Actions)
    • Loop - Actions
      • Set point = (z_leakRemove_point offset by 600.00 towards (270.00 + ((Real((Integer A))) x 40.00)) degrees)
      • Unit - Create 1 dummy_evilSorcerer_shots for Player 11 (Dark Green) at point facing ((Angle from point to z_leakRemove_point) + 90.00) degrees
      • Unit - Add a 5.50 second Generic expiration timer to (Last created unit)
      • Special Effect - Create a special effect at (Position of (Last created unit)) using Abilities\Weapons\FrostWyrmMissile\FrostWyrmMissile.mdl
      • Special Effect - Destroy (Last created special effect)
      • Custom script: call RemoveLocation(udg_point)
  • Custom script: call RemoveLocation(udg_z_leakRemove_point)

The set bj_wantDestroyGroup = true should be placed here:

• Move shots
  • Events
    • Time - Every 0.01 seconds of game time
  • Conditions
  • Actions
    • Custom script: set bj_wantDestroyGroup = true
    • Unit Group - Pick every unit in (Units of type dummy_evilSorcerer_shots) and do (Actions)
      • Loop - Actions
        • Unit - Move (Picked unit) instantly to ((Position of (Picked unit)) offset by 2.00 towards (Facing of (Picked unit)) degrees)
        • Unit - Make (Picked unit) face ((Angle from (Position of Evil Sorcerer 0059 <gen>) to (Position of (Picked unit))) + 120.00) over 0.00 seconds

ah thanks. The set bj_wantDestroyGroup = true stops the actions though and they dont move at all. I guess I need to destroy the group afterwards.

 

[BloodSoul]

Actually, that's what the bj_wantDestroyGroup does, and it shouldn't stop moving those units.

 

[Nordmar]

but it does stop them

Either way, it's better to create a unit group when the game starts and only add the units that are supposed to turn around the caster - It wouldn't be a good idea to enumerate through all units of a player just for that.
