[Speed-dreams-devel] Ri: Re: hi all

[Paolo G. <gh...@me...>]

thanks for the quick reply..
I wish made a new thing, a new test...
I modified this:

 // compute suspension travel
RtTrackGlobal2Local(car->trkPos.seg, wheel->pos.x, wheel->pos.y, &(wheel->trkPos), TR_LPOS_SEGMENT);
wheel->zRoad = Zroad = RtTrackHeightL(&(wheel->trkPos));

with my personal function to raycast
but 2 questions: the wheel.pos is the position in world coordinates to the center of the wheel, and after zRoad is the world coordinate z for the xy point, so in my case, the ray hit the world at zRoad z coordinate..

merci beaucoup et bonne soireè!

Paolo

Hi Paolo,

you'll have a problem, the entire 3D positioning, collision, etc. is
handled by the simulation code.
Management track with just 3D (no xml) can not be run by robots
including the player.

For the contact, it's managed by simu module.

Cheers
