How to make a unit move in a circle?

[nafre]

Can someone tell me how to make a unit move in a circle. Like in this lasso spell http://www.hiveworkshop.com/forums/spells-569/lasso-198558/ . I cant seem to understand how to make the unit move in that way. Can someone post a simpler trigger. thx in advance. P.S. It is ok if it is not mui.

k i ve made a spell so

in spell int i've selected the group :

• Set KamuiGroup = (Units within 400.00 of KamuiPoint1[KamuiInt] matching ((((Matching unit) belongs to an enemy of (Owner of KamuiCaster[KamuiInt])) Equal to True) and (((Matching unit) is alive) Equal to True)))

and in loop

• Unit Group - Pick every unit in KamuiGroup and do (Actions)
  • Loop - Actions
    • Set KamuiDamage[KamuiInt] = ((Angle from (Position of KamuiDummy[KamuiInt]) to (Position of (Picked unit))) + 270.00)
    • Set KamuiPoint1[KamuiInt] = (Position of (Picked unit))
    • Set KamuiPoint2[KamuiInt] = (KamuiPoint1[KamuiInt] offset by 5.00 towards KamuiDamage[KamuiInt] degrees)
    • Special Effect - Create a special effect attached to the chest of (Picked unit) using KamuiEffect.mdx
    • Special Effect - Destroy (Last created special effect)
    • Unit - Move (Picked unit) instantly to KamuiPoint2[KamuiInt]
    • Unit - Cause KamuiCaster[KamuiInt] to damage (Picked unit), dealing 3.00 damage of attack type Spells and damage type Normal
    • Custom script: call RemoveLocation (udg_KamuiPoint1[udg_KamuiInt])
    • Custom script: call RemoveLocation (udg_KamuiPoint2[udg_KamuiInt])

hope you will understand

That way leaves a unit group leak per execution.
Use an if/then/else around the above trigger
If Number of units in group > 0 then <Actions> else
call udg_DestroyGroup(udg_group)
Turn off <This trigger>

Although the thread title may be misleading, this is related.

Here are some specific posts that could help you:

Basically you're just taking the center of the circle and move the unit around it (well, duh).
Further explanation:
If a unit "U" is 200 range away from the center of the circle, and is currently at an angle of 90º (that means at the top of the circle, I hope you still know the all-important Unit Circle).
If you want to make him move in a circle (let's say counter-clockwise, which is the easiest), then you just have to move unit U 200 range from the center of the circle towards 92º!
And after that 94º, 96º, 98º, etc... until we complete our circle. Our unit will now move in a circular movement around the center location. If we speed up this process to about 30 movements a second, then it will move seamlessly.

I'm afraid I cannot explain this any better without having to delve deeper into the very basics of math, which I do hope you already know.

This is a simple Circular Motion trigger. (excluding the advance Centripetal Force formula, lol)
