How to make a unit on a point behind a caster?

[nardretor]

Im currently making an ability that summons a gigantic spider behind the caster, doing an attack animation, then it disappears, making all enemy units infront of it pushed back. The only thing i cant do is to get a point behind the caster. It's like this


E-E-E--------C---P
enemies---caster--point

Thanks for those who will help. Ask more questions if you like.

Set the position of casting unit to a variable. Then use point with polar offset. Offset the new point 200 or so range from the position of the casting unit offset by 180 degrees. That should do what you want. And create the spider at that new position, facing the casting unit's facing, and play its cast/attack animation.

should do if you use the caster's angle + 180 degrees in the offset

Can you please show me a sample trigger this? probably the range between the point behind and the caster point is 2 centimeters based on screen.

• Actions
  • Set TempPoint = (Position of (Triggering unit))
  • Set TempPoint2 = (TempPoint offset by 100.00 towards ((Facing of (Triggering unit)) + 180.00) degrees)

That "TempPoint2" is stationed 100 range behind triggering unit

That "TempPoint2" is stationed 100 range behind triggering unit

if you did

Set TempPoint2 = (TempPoint offset by 100.00 towards ((Facing of (Triggering unit)) - 180.00) degrees)
(notice the - 180 degrees)

would this offset point be in front of the casting unit???

Nope... That is the same thing

I just chose to do "+" instead

Since a complete circle would be 360 degrees, 180, whatever way, negative or positive, you put it in, will be the same since it's half of a circle.

Infront of the unit would be +0 or -0

well... Komaqtion's actions worked. Thanks people
