hallo,

kann mir jemand anhand eines beispiels erklären, wie ich mit newton ein bewegungsscript für nen gleiter mache? (Mit gleiter meine ich sowas wie nen pod-racer aus STARWARS) Ich hab mir das newton 1.51 oder so grad installiert, aber das handbuch zeigt nur, wie ich ner entity eine vorgefertigte aktion zuweise....ich blick überhaupt nicht durch, was ich jetzt machen soll....kann mir jemand bitte von grund auf erklären, wie ich son bewegungsscript für nen gleiter machen kann?
Ich hoffe, mir kann das jemand erklären

MfG Efrint

ok...in english:
could somebody explain, how to do a movement-script for a glider (with glider, I mean something like a pod-racer in StarWars). I don´t know, how i could do this....and...in the newton-manual is nothing written about self-programming of newton-physic-scripts....It would be great, if somebody could help me....

Regards Efrint

ist nen gleiter nicht bissl viel für nen absoluter newton neuling?

well, just a small suggestion...
make a newton car, make the car body a glider model, and normall attach the wheels, then make the wheels invisble, and it looks like it's floating, just like a pod would do.

regards,

@ 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

probier es mit c-script
und warte auf die neue newton version die ventilator macht
die autos in newton haben nen bösen bug der dann behoben ist

ok...wie mache ich es, dass die karre immer "korrekt" auf der straße liegt? Zum Beispiel in nem looping?
