Well another knockback system, I hope can be useful for someone 
JASS:
library KnockbackTools uses Optimizer32, Event, DestructableLib, AutoFly
/*****************************************************************************
*
* KnockbackTools
* _______________
* v1.1.1.1
* by Thelordmarshall
*
* Well another fucking Knockback system...
*
* Pros:
* _____
* You can:
* - Use slide speed or not.
* - Use fly on launch targets.
* - Create functions for loop/stop events.
* - And more....
*
* API:
* ____
* struct Knockback extends array:
* - method launch takes real angle, real distance returns nothing
* - Launch the target.
* method operator:
* - useSlideSpeed (boolean)
* - speed (real)
* - timerSpeed (real)
* - arc (real)
* - fx (string)
* - pathing (boolean)
* - pause (boolean)
* - fly (boolean)
* - hitTrees (boolean)
*
* Functions:
* __________
* - function Parabola takes real arc, real d, real x returns real
* - function ParabolicMovement takes real h, real d, real x returns real
*
* Credits:
* ________
* - Nestharus: Event.
* - PitzerMike: DestructableLib.
* - moyackx: Parabolic formulas.

. I'm working on the next version ...'ll fix it, don't worry.
