bone rotation issue

[badday]

Hi,

I´m trying to point a barrel to some target. In order to do so I´ve got a bone. Now I´m trying to rotate that. But nothing happens.

Let´s say I´ve got a scene::IBoneSceneNode *b which got it´s value by node->getJointNode("boneName"); It does get a valid value, so there is a bone with that name in the animation file (.X).

Now I tried

Code: Select all

while(device->run())
	{
		
		b->setRotation(b->getRotation() + vector3df(1, 0, 0));
		
		driver->beginScene(true, true, SColor(255,100,101,140));
		smgr->drawAll();	
		gui->drawAll();
		driver->endScene();
	}

This should at least show some effect. But it doesn´t.

I tried to set b->setRotation(vector3df(0,0,0)); before the loop, but all results in the same: after 1 iteration true the loop, values stay the same, namely:

{,,Irrlicht.dll}((*(irr::scene::ISceneNode*)(&(*(irr::scene::IBoneSceneNode*)(&*(irr::scene::CBoneSceneNode*){*}b))))).RelativeRotation {X=180.10611 Y=89.410172 Z=179.71519 } irr::core::vector3d<float>

This doesn´t change any more.

Furthermore I noticed that rotationHint is set to -1. Is this a problem?


A lot of questions, I just hope someone can help me.


Thanks,

is the barrel weighted painted?

you are using blender exporter?

blender exporting skinned meshes is common very problem here.

Try:

Code: Select all

while(device->run())
   {
      
      node->animateJoints(); // let Irrlicht animate the joints. Make sure you`re using EJUOR_CONTROL
      b->setRotation(b->getRotation() + vector3df(1, 0, 0)); // apply your rotation
      
      driver->beginScene(true, true, SColor(255,100,101,140));
      smgr->drawAll();   
      gui->drawAll();
      driver->endScene();
   }

You´re right, shadowslair. I did forget this.

Thanks a lot, problem is solved
