Unit facing

[PandaBear]

I want to create an ability kinda in the DotA spell Ice Wall style, it creates a wall wherever the unit is looking at (facing angle). How can I create this wall in GUI?

Sorry if it's confusing, I just don't know how to explain that bether..

So what exactly is this wall supposed to be? Would it be some sort of unit, or doodad of some sort? Well anyway, when your choosing the position of the wall to be in, use Point with Polar Offset, and use Unit Facing Angle when you need to enter an angle.

Well the wall would be made Dummy Units with some cool model

Here is a pic of what i want to do (notice that I suck with photoshop )

The A would be the casting unit, the arrow shows the facing angle of the A unit and the r line would be the wall

Well you would want to do something along the lines of

• trigger
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Your Ability
  • Actions
    • Unit - Create 1 Your Unit for (Owner of (Triggering unit)) at ((Position of (Triggering unit)) offset by 300.00 towards (Facing of (Triggering unit)) degrees) facing Default building facing degrees

Hm...

This would create 1 unit right? Here is where im stuck: how can I create the other units, in the line shown on the picture above?

You would need to add or subtract from the facing angle and increase the distance from the caster for each new unit. You'll have to experiment to find out exactly how far you need to adjust each unit.

Guess I'll have to find a formula using the distance and angle to find the perfect position...

@Edit
Finally did it! Thanks for your help!

i see you finally did it but.... theres an easier way then trial and error

Get the point of somewhere directly infront of the caster, this will be our base point
Get the angle of the caster to the point, this will be our base angle
Make a loop for however big you want the wall, make sure the starting number is a negitive of the ending number (IE -12 ~ 12)
Set point 2 based off of Point 1 with a polar offset of 64 (this real offset can be whatever you want) x The integer loop your with a polar offset angle + 90 (4got if this was to the unit's left of right, dosent really matter itll make it a line anyways>
Make the "ice" unit at point 2
Add whatever you want, abilities, durations, coloring of the unit blah blah
Remove point 2 from the game
end loop
Remove point 3 from the game

This will basically take the point onfront of your caster, and make a line base on what angle he is facing (the offset in reality is a constant, +90 of any angle will be to the left (or was it right) of your inital angle. From there the negitive integer in the loop will take care of the other side of the line.)

How would this be in the Trigger Editor? I'm trying to do this way but somehow its making a square
