Attacking using ability

Can anyone help me with this? I'm trying to figure out how to attack using an ability. For Example: I'm using wind walk. When i use wind walk I will do attack animation and this is the part I can't firgure out.. How to damage area infront of the unit using wind walk. I've tried some stuff but it still killed a person when I had my back turned... Can someone help?

Ok then more understandable.

I am using the arrow keys to move and the [W] HOTKEY for wind walk ability to shoot.

I have an event set like this

Event: When ability begins being cast

Condition: Ability equel to wind walk

Action: Unit-Damage Area-Cause (unit) to damage 100000 in 250 radius at position of (unit casting ability with offset. ( I don't know what to do at the offset part to make unit damage area 400 range in front of him)

This question is difficult to understand.

If you take a bit more time to explain in more detail what you are trying to do and possibly your approach to doing it so far, maybe someone can help you.

Seems your trigger is going in the right direction. Let me clarify some terms for you, if you do not already know. If you already know, I am sorry.

Radius - A circle (or a circle of 250 size in your case)
Offset - Edited position of the circle.
X - Horizontal Offset
Y - Vertical Offset

In short...

Is the trigger you want. What you needed was the "Unit Facing Angle".

Ok, I have it set exactly like that and it makes me get hit. (The Caster)
When I use the trigger my person dies.
Trigger:
Unit - Cause (Triggering unit) to damage circular area after 0.00 seconds of radius 250.00 at ((Position of (Triggering unit)) offset by ((Facing of (Triggering unit)), ((Facing of (Triggering unit)) + 200.00))), dealing 99999.00 damage of attack type Spells and damage type Normal


PS: UPDATED! I just figured it out at 12:56 a.m. It is backwards. Its offset by ((Facing of (Triggering unit +400)), ((Facing of (Triggering unit)) I added a 200 to make sure i dont shoot myself.

Thanks for the help on that.

Arithmetic allows you do the " + "

Hmm triggers, moved.
