facing angle abilities

[goldDannsp]

well, i am a begineer in map making, and the thing i want to know is how can i make an ability that works in the facing angle of the caster. example: ballista of black pearl in battle ships pro, i only need you to explain me how this works:thup:

Well it would help to know exactly what you're trying to do, but you're going to need to use Unit - Facing Angle.

he wants to do a spell that only works in one direction of a unit, for example in front of the caster

 

[goldDannsp]

yes, i need that, anyone knows how?

 

[Komaqtion]

Well, so you basically want (For example) a projectile to be sent out in the facing of the caster ? (This is an instant spell, right ? )

Then, the basic concept is to maybe use a dummy unit, and then use that unit as the projectile...
And simply move it in the direction the caster is facing...

Here's a sample trigger for you to study (The first ones are not MUI, and not even MPI)

Frst way:

• Projectile Facing
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Ability 1
  • Actions
    • Set TempPoint = (Position of (Triggering unit))
    • Set TempPoint2 = (TempPoint offset by 500.00 towards TempReal degrees)
    • Set TempReal = (Facing of (Triggering unit))
    • Unit - Create 1 Dummy for (Owner of (Triggering unit)) at TempPoint facing TempReal degrees
    • Set Dummy = (Last created unit)
    • Trigger - Turn on Projectile Moving <gen>

• Projectile Moving
  • Events
    • Time - Every 0.04 seconds of game time
  • Conditions
  • Actions
    • Set TempPoint3 = (TempPoint offset by 10.00 towards TempReal degrees)
    • Custom script: call RemoveLocation(udg_TempPoint)
    • Unit - Move Dummy instantly to TempPoint3, facing TempReal degrees
    • Set TempPoint = (Position of Dummy)
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Distance between TempPoint2 and TempPoint3) Less than or equal to 5.00
      • Then - Actions
        • Custom script: call RemoveLocation(udg_TempPoint)
        • Custom script: call RemoveLocation(udg_TempPoint2)
        • Trigger - Turn off (This trigger)
      • Else - Actions
    • Custom script: call RemoveLocation(udg_TempPoint3)

Second way (MUI):

• Projectile MUI Init
  • Events
    • Map initialization
  • Conditions
  • Actions
    • Hashtable - Create a hashtable
    • Set TempHash = (Last created hashtable)

• Projectile Facing MUI
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Ability 1
  • Actions
    • Set TempPoint = (Position of (Triggering unit))
    • Set TempPoint2 = (TempPoint offset by 500.00 towards (Facing of (Triggering unit)) degrees)
    • Unit - Create 1 Dummy for (Owner of (Triggering unit)) at TempPoint facing TempReal degrees
    • Hashtable - Save (Facing of (Triggering unit)) as 1 of Key (Last created unit) in TempHash
    • Hashtable - Save Handle OfTempPoint as 2 of Key (Last created unit) in TempHash
    • Hashtable - Save Handle OfTempPoint2 as 3 of Key (Last created unit) in TempHash
    • Unit Group - Add (Last created unit) to Periodic_Group
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Number of units in Periodic_Group) Equal to 1
      • Then - Actions
        • Trigger - Turn on Projectile Moving MUI <gen>
      • Else - Actions
    • Custom script: call RemoveLocation(udg_TempPoint)
    • Custom script: call RemoveLocation(udg_TempPoint2)

• Projectile Moving MUI
  • Events
    • Time - Every 0.04 seconds of game time
  • Conditions
  • Actions
    • Unit Group - Pick every unit in Periodic_Group and do (Actions)
      • Loop - Actions
        • Set TempPoint = (Load 3 of Key (Picked unit) in TempHash)
        • Set TempPoint2 = (Position of (Picked unit))
        • Set TempPoint3 = (TempPoint2 offset by 10.00 towards (Load 1 of Key (Picked unit) from TempHash) degrees)
        • Unit - Move (Picked unit) instantly to TempPoint3, facing (Load 1 of Key (Picked unit) from TempHash) degrees
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • (Distance between TempPoint and TempPoint3) Less than or equal to 5.00
          • Then - Actions
            • Unit Group - Remove (Picked unit) from Periodic_Group
            • Unit - Remove (Picked unit) from the game
            • Hashtable - Clear all child hashtables of child Key (Picked unit) in TempHash
            • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
              • If - Conditions
                • (Number of units in Periodic_Group) Equal to 0
              • Then - Actions
                • Trigger - Turn off (This trigger)
              • Else - Actions
          • Else - Actions
        • Custom script: call RemoveLocation(udg_TempPoint)
        • Custom script: call RemoveLocation(udg_TempPoint2)
        • Custom script: call RemoveLocation(udg_TempPoint3)

Hope this helps a little bit

yes, the first way works properly but in the second when i set the action ´´HandleOftempPoint as 2 of 0 in temphash´´ the world editor shuts down and sends me an error, but thanks for the first way:thup:

 

[goldDannsp]

yeah, i made that ability and it works well but it does not affects air units, here are my triggers: ( my world editor is in spanish )

It damages only ground units, can anyone tell me how i can do to damage both ground and air units??:banghead:

 

[Komaqtion]

Sorry, I edited the triggers now, and they should work now :S

Anyways, why would you use a 0.04 event, when you wait 0.8 seconds ? :S

And, this should be simply "Move unit" not "Order unit to move":

• Unidad - Order (Last created unit) to Mover a (TempPoint offset by 1000.00 towards TempReal degrees)

• Unit - Move Dummy instantly to TempPoint3, facing TempReal degrees

You should also replace all (Last created unit) with "Dummy" (The variable )

Take a look at my last post again

 

[goldDannsp]

i made the changes and the trigger works good,:thup: and i replaced the last trigger with the ´´non objective´´ trigger, but it only damages ground units, i want to know why?, ah and i put that ´´wait 0.80´´ because if i remove it, the trigger moves too quick and don´t lets the explosion part work fine, and it damages the caster.
