@ dennis fantasy thx...i´l try it...
@ samb wieso? Was soll ich denn sonst probieren? Außerdem brauch ich das script....

Regards Efrint

Edit:

ok...i did with the premade newton-vehicle-script a new one. but i receive two errors:
movement.wdl 55:0 Error(0) Bad or missing parameter unknown function
movement.wdl 68:0 Error(63)Parameter unknown tyrebegin

here is the code:

i hope, you can help me
