[IrrBullet] Issue using IConvexHullShapes

[InstinctCH]

Hey everyone !

I've got a weird issue when using the IConvexHullShapes from irrBullet. My Rigidbodies dont rotate, no matter how they hit the ground, they stay in the same position. Here's a screen of the issue:



Maybe you want to see the code so here it is:

Code: Select all

 
    vector3df pos = camera->getAbsolutePosition();
    pos.Y-=0.4;
    IAnimatedMeshSceneNode *Node = device->getSceneManager()->addAnimatedMeshSceneNode(device->getSceneManager()->getMesh("MODELS/OTHER/M9mag.b3d"));
 
    Node->setMaterialTexture(0, m_magTex);
    Node->setScale(vector3df(0.3,0.3,0.3));
    Node->setPosition(pos);
    Node->setRotation(vector3df(0,0,0));
    Node->setMaterialFlag(irr::video::EMF_LIGHTING, true);
    Node->setMaterialFlag(irr::video::EMF_NORMALIZE_NORMALS, true);
 
        ICollisionShape*  shape = new IConvexHullShape(Node, Node->getMesh(), 0.02);
        //shape->setMargin(0.01);
 
        IRigidBody *body = world->addRigidBody(shape);
        body->setCcdValues(0.02,0.02);
 
 
    return body;

Nobody has an idea why IrrBullet is doing this?

erm, try drawing everything with debug drawer.

Okay but I don't see what will help me if I draw debug infos..

A lot! See this post for a debug drawer.

Edit: I see you are using IrrBullet, maybe it got its own debug drawer.

[InstinctCH]

Yes it has its own debug drawer. But everything is working fine, except for the rotations. The rigidbodies just stay in the same rotation as they were created.

you should post a screenshot with rigid bodies dropping with enabled debug drawer (set everything to on.)
There is a way in bullet to lock rotations on specific axis, but from the code you shown it doesn't seem like you're doing that.

I just found this post from jaeg: http://irrlicht.sourceforge.net/forum/v ... 15#p257845

He says that he isn't able to apply forces to his characters when using an IConvexHullShape so I guess it's normal. I think I'll stay with my IBoxShape, although there are many tunneling issues.
