Ball joint limits bug using beta 2.05

[Leadwerks]

The pin argument for the ball joint limits command does not appear to work correctly. If I set the pin to (0,-1,0) and the max cone angle to 45, it works as expected. In this demo I set the pin to (1,0,0) and the movement is not centered around that vector; It doesn't even move in a cone shape:

The source code is the bjl.bmx file.

you are using a Build in joint which is not longer reliable in 2.00
can't you use a 6DOF, it can reproduce that joint very eassy.

[Leadwerks]

Do you have code for a custom 6DOF ball and socket joint with limits?

Are the built in joints becoming deprecated / unsupported in Newton 2.0 in favor of the new joint library? That would be good to know.

[Julio Jerez]

Oh I see it is difficult to make cone and twist the limits for a ball and socket with the 6DF.

BallAndSocked with limits is in the jointLibray, I will add it to the C inerface this weekend,
Plus I will add some more too.

Are the built in joints becoming deprecated / unsupported in Newton 2.0 in favor of the new joint library? That would be good to know.

I did not spent time on then, I just change the inetface so that they continue compiling.
It is why I added the Joint Library which replicates all of the internal joints.

Thanks.

This is what it will be used for:

Are you using BallAndSocket joints for RagDoll?

there is a Rag doll Joint in the joint Library that is very nice to set limbs.
It also has correction to prevent dismembering.
It is cool because it have ways to set limit better than using plain BallAndCockets and hinges

[Leadwerks]

I need hinge and ball limits to be working properly, anyways, because they are features my engine is supposed to support. Hinge limits are working fine as of 2.05.

I would really like slider limits, too, so I can make a desk with drawers that can pull out and stop.

[Julio Jerez]

download beta 2.06, it adds BallAndSockect, and Slider joint to the C inteface of joint library

[Leadwerks]

Thanks, both are working great now.
