[Trigger] Two things, very simple: why don't they work?

[Marine]

I've got this dragon rider guy. He has four abilities; Move Up, Move Down, Turn Right, and Turn Left. When an ability is cast, his Current Height or Facing Degree is increased or decreased depending on the ability used. Here are the four triggers with each one:

Move Up

• Move up
  • Events
    • Unit - A unit Begins casting an ability
  • Conditions
    • (Ability being cast) Equal to Go Upwards
  • Actions
    • Set Dragon_Height = (Current flying height of Dragon Rider 0001 <gen>)
    • Animation - Change Dragon Rider 0001 <gen> flying height to (Dragon_Height + 50.00) at 50.00

Move Down

• Move down
  • Events
    • Unit - A unit Begins casting an ability
  • Conditions
    • (Ability being cast) Equal to Go Downwards
  • Actions
    • Set Dragon_Height = (Current flying height of Dragon Rider 0001 <gen>)
    • Animation - Change Dragon Rider 0001 <gen> flying height to (Dragon_Height - 50.00) at 50.00

Turn Right

• Move right
  • Events
    • Unit - A unit Begins casting an ability
  • Conditions
    • (Ability being cast) Equal to Turn Right
  • Actions
    • Set FacingDegree = (Facing of Dragon Rider 0001 <gen>)
    • Unit - Make Dragon Rider 0001 <gen> face (FacingDegree + 50.00) over 1.00 seconds

Turn Left

• Move left
  • Events
    • Unit - A unit Begins casting an ability
  • Conditions
    • (Ability being cast) Equal to Turn Left
  • Actions
    • Set FacingDegree = (Facing of Dragon Rider 0001 <gen>)
    • Unit - Make Dragon Rider 0001 <gen> face (FacingDegree - 50.00) over 1.00 seconds

NOW, the problem. When I used arrow keys to use this triggers (instead of A unit Begins casting an ability, it was Keyboard Event - Up/Left/Right/Down Arrow Key is Pressed), there were no problems; everything worked great. So, now, switching to the abilities, the dragon only turns left. Whether I am doing Move Up, Move Right, Move Down, or Move Left, the dragon only turns left. If anyone knows a solution to this, please help!

The Second Problem

I want my dragon rider fellow to be constantly moving forward, whether I am turning, going up, or going down; he should be in constant motion. I've tried making him move to a variable point set at an offset that would urge him to move forward after a second, but that didn't work; he only wanted to move to that single point even after he turned (the variable was set within the periodic event, so it should have changed?). So, if anyone can help me with this, it would be very much appreciated. Thank you.

Are the ablities all based off of the same base ability / same base order id? (meaning you copied the same abiltiy 4 times). If so, than you should switch to "Instant" channel spells, each with unique base order ids.

on 2nd one

• Untitled Trigger 004
  • Events
    • Time - Every 0.10 seconds of game time
  • Conditions
  • Actions
    • Unit Group - Pick every unit in YourGroupOfUnitsToMove and do (Actions)
      • Loop - Actions
        • Set TempLoc = (Position of (Picked unit))
        • Set TempLoc2 = (TempLoc2 offset by 25.00 towards (Facing of (Picked unit)) degrees)
        • Unit - Order PickedUnit to Move To TempLoc2
        • Custom script: call RemoveLocation(udg_TempLoc)
        • Custom script: call RemoveLocation(udg_TempLoc2)

if ur only moving one unit, you can just remove the unit group and change picked unit to your unit

For Event, I think you should use the Starts the effect of an ability

I'm not sure but, to set the fly heights of units, I think you have to give them the ability Crow Form and remove it.

As for your second problem, just make a periodic event that moves him every .03 seconds?

• Constant Movement
  • Events
    • Time - Every 0.03 seconds of game time
  • Conditions
  • Actions
    • Set NewPoint = ((Position of Dragon) offset by 30.00 towards (Facing of (Dragon)) degrees)
    • Unit - Move (Dragon) instantly to NewPoint

NewPoint is a point variable, Dragon is the unit that is being moved. For this trigger to work, you have to set Dragon to the unit you want moved in your map. You do this by using

• Set Dragon
  • Events
    • Map Initialization
  • Conditions
  • Actions
    • Set Dragon = (Which Unit)

For this case, it's better for him to use the SetUnitX/Y as it does not interrupt orders (and making the unit to be able to cast or receive another orders from Players)

If you use Move Unit (Instantly) function, it will make that unit pretty much impossible for it to cast any other spell (for him to cast the spell Move Up/Down/Left/Right)

1) Maybe you use the same ability, it will conflict the orderID's, change it...

2) Use this...
