Greetings!

I'm experiencing a problem, hopefully a newbie problem that can be easily fixed.

I have two entities registered on the Rigid collection, with different groupIDs.

One is a ball with mass, the other is a plate with zero mass.
When the ball touches the plate, the plate(which have an initial inclination of 45 degrees) quickly rotates to zero degrees, the ball rotates too in her's z-axis and the simulation halts.

If the plate have a different mass, the simulation works, but it meant to be a "fixed object" as referred in 3DGS manual. I don't want the plate to move

What am i doing wrong?


action Ball()
{
phent_settype(my,PH_RIGID,PH_SPHERE);
phent_setmass(my,50,PH_SPHERE);
phent_setdamping(my,0,0);
phent_setfriction(my, 60);
phent_setelasticity(my,80,1);
phent_setgroup(my,2);
}


action Terrain()
{
phent_settype(my,PH_RIGID,PH_POLY);
phent_setmass(my,0,PH_POLY);
phent_setdamping(my,0,0);
phent_setfriction(my, 10);
phent_setgroup(my,4);
}

Gravity (0,0,-386) and Groupselection (6) are set elsewhere.

Any ideas?

the poly doesnt work that great use box ore somtingh other thing you cold try to decrease the speed of the ball thats going to the terain and set ph_check_distance = 1; to one ore somthing the problem will be a litle bit less suck
also you cold try somthing white ph_iterations = 1; btw(i could decrease a lot of fps)

Thanks for the reply.

I've tried your tips.
Each one individually and then all together, with the values you said, and again with extreme values.
The functions work because i can see whats happenning with every new set of values but the ball just sticks to the fixed plate.
In POLY the ball sticks to the geometry itself, and BOX touches the box boundaries and quickly sticks to the geometry.

Any more ideas ?

3DGS physics entities react to regular entities, so the terrain action is not necessary

Hmm, works great this way! Thanks!
The idea was setting new friction and damping values according to the type of terrain below, that way a simple c_trace covers it. Thanks again
