hi all,

Could be added to XPal a method to enable/disable a Bodies and Colliables?

I have looked that add/removing from world or ColliableGroups cause some
stranger behaviors.

Thanks,
Sisso

I'm not sure. It would have to be done in the JOODE/Odejava implementation, which is where my knowledge ends. Is there anybody, who know a bit more about JOODE/Odejava internals?

In the Odejava you can disable a geometry by changing the flags:

Code:

geom.gflags &= ~Geom.GEOM_ENABLED;

But i don't known if it really works and if there the same thing to bodies.

I will try to get a time to look this...

Thanks,

I am back,

Ok, I said wrong, this is for joode.

Joode Collidable flag:

Code:

geom.gflags &= ~Geom.GEOM_ENABLED;

Joode Body flag:

Code:

body.flags & ~net.java.dev.joode.Body.dxBodyDisabled

I added a method setEnabled to Collidable and Body.
It is very easy to do in joode and it works.

For OdeJava there is a method "Body.setEnabled" and "Geom.setEnabled", I don't tried this but if the method exists It should work

Thanks,

OK, I will add this when I have a second of time.

From what I have seem of the Odejava source I am afraid, it won't. Odejava is extremely dirty coding and has many bugs and unimplemented stuff. The whole collision-without-simulation stuff is not cared about at all. I had to fix/implement several things to make it to the point where the XPAL implementation is now. No I have to wait for an ODE bug to be fixed.

BTW Marvin it's interesting that you realize now why I chose (earlier) JOODE as the first citizen in the XPAL land. Odejava would have a lot more of users if it had better support / was better maintained.. I know some that since William Denniss is gone, some jME guys have been working on it, I hope it's still moving forward.

Just to make sure, that this is known: Bodies and Collideables now have a set/isEnabled getter/setter pair. Additionally the Body has a set/isGravityEnabled() getter/setter pair.
