Dummy unit move

how to make a spells that create a dummy unit who move around the caster to make a circle path???

Move the unit in a circular manner...
Make a periodical trigger or a loop that moves a unit instantly to a point with a polar offset
Unit - Move (unit) instantly to (location) offset by x towards y
Set y = y + 1

What i do if i want it do damage to ppl get hitted by dummy unit?

add perma immolate to him. Or make a trigger that does damage to every unit within range of the dummy unit.

i got a problem.. It dont move around the caster...

Then show your triggers

there something for show trigger but I don't know how it work. so i will write it...

Trigger1
Events
Unit - A unit start the effect of an ability

Conditions
(Ability being cast) equal to Test

Actions
Unit - Create 1 dummy for (Owner of (triggering unit)) at ((Position of (triggering unit)) offset by 150.00 towards 360 degrees) facing (Position of triggering unit)
Trigger - Turn on Trigger2<gen>
Wait - 5 seconds
Trigger - Turn Off Trigger2<gen>
Unit - Kill (last created unit)


Trigger2
Events
Time - Every 0.01 seconds of game time

Conditions

Actions
Unit - Move (Last created unit) instanly to ((Position of (Casting unit)) offset by 150.00 towards Y degrees)
Set Y = (Y+3.00)

there is no casting unit in your 2nd trigger

add the caster into a unit variable in the first trigger and refer to it in the second trigger

Oh it work thanks. your so good
