--[[
PickUp Particlesystem für Pressen oder Ladewagen.

Vorlage war hier die Claas3200.lua von TTM!

Anpassungen:				Ifko[nator]
Erstellt/angepasst am:		25.06.2013

Fix: Nun wird kein PS mehr erzeugt wenn man einen Ladewagen entleert.

Gefixt von Ifko[nator] am:	03.07.2013

Edit: 18.08.2013

Geändert wurde: StaticParticleSystem für die KronePickupParticleSystems direkt eigebunden damit keine extra lua mehr notwendig ist.

Geändert von: Ifko[nator]

Dieses Script ist Freiverwendbar! Sollt es ja auch nutzen.. ^^

Für fragen bin ich via PN: 

auf www.ls-mapsource.de als "Ifko" 

oder auf www.modding-welt.com als "Ifkonator" zu erreichen.
