Thank you, the engine is almost at the bottom of the script, now it only returns an error at line 63:
Code:
effect(laserAspezial,max(1,laserAAnzahlPartikel*time_step),p.x,nullvector);

It says:

Error in 'laser1.c' line 63: 'max' undeclared identifier

The best games are the games you create yourself.
