[vJASS] Circle that expands // Movements & Collisions

[mateuspv]

Spell: creates four units that begin to spin and gain distance from the caster.

notes:
1 - If the caster move the move also unidedes
2 - When reaching distance equal to 700 take 100 damage in his back
3 - If a units collide with a monster, it explodes causing damage

the problem is that I never made such a spell like this

frist,What library is recommended?


*I intend to use this topic for future questions about the code

Maybe Table or something?
You don't really need a library for this (aside from the one you create yourself).

Store the caster X/Y, the angle and the current distance to the caster, then periodically move him further away while adjusting the angle.
With a few checks, you can see if there's another unit nearby.
