Hi,

I have some problems with the physics engine.
I have 4 wheels that are about an inch in mid-air, and as soon as they touch the ground, they sink in and start to do weird things.

I can't figure out what's causing them to go berserk...

EDIT: all the ph_ and phent_ setting:

Code:

---

ph_setgravity (vector(0,0,-100));

(the following are set in actions)
phent_settype (me,PH_RIGID,PH_CYLINDER);
phent_setmass (my, 3, PH_SPHERE);
phent_setfriction (my, 100);
phent_setdamping (my, 40, 40);
phent_setelasticity (my, 50, 20);

List all your ph_ and phent_ settings. To get wheels to work it is my understanding you have to tweak corrections and such to make it work. Others would know better than I (don't work with wheels) but listing your settings would be a good first step.

I edited my first post and added the ph_ and phent_ settings

ph_cylinder is notoriously buggy and not recommended for use by several forum members who have triedc to get it working.

Switch to ph_sphere and see if that helps.

If only i knew...

Thanks! It solved everything !

how did you solved it? you got ph_cylinder to work?
everyone here wants to know it

No I just used PH_SPHERE instead, but surely ill play around with PH_CYLINDER since that is what i need. Is there anything i should know before messing with PH_CYLINDER?

EDIT: Instead of creating another topic, I would like to know if its possible to rotate a constraint itself? <------- nevermind, I found out by myself: I can use phcon_getpostion().

EDIT2: How am i suppose to know exactly where to place my anchor points ?

anyone ?

Just for information: I think (my opinion) cylinder is a mess in several physic engines.
For example, GTA uses spheres to define the tires, not cylinders!
I don't know if they do this for performance reasons or for other problems (bugs in several physic engine?)... however...

I don't know if cylinders are renown to be buggy in several engines, but if it is... Houston, we have a problem.

I'll go take a quick look to see if it's a known bug elsewhere.
