[SOLVED]Cube seems to be moving

[onesixtyfourth]

I have added a cube to a scene (I am simply using the quake castle scene from tut 2) and I am rotating it. No problem in that but as I move the camera around the cube appears to be changing position. Is it just appearing to do so or has anyone seen this before?

Code I use to add cube

Code: Select all

 
//add cube seems to be moving
    scene::ISceneNode *cubeOne = smgr->addCubeSceneNode(10.0f, 0, -1,
                                                    core::vector3df(10,10,5),
                                                        core::vector3df(0,0,0),
                                            core::vector3df(0.25f,0.25f,0.25f));
 

I am using rotation function I found here and the movement seems to occur whether or not I am using this.

Your cube is not at the origin of your node. If you rotate the node, the cube will describe a circle.

Put the cube at the centre of the node and then translate the node.

Well the cube rotates ok the movement appears to be from the camera perspective. So if I stay still and view the cube it rotates nicely. If I move the camera the cube appears to alter position and even size.

Well you seem to have been correct as I now create the cube with no arguments and the movement seems to have gone. I am now altering the position of the node with set position after creation which is what I thought I was doing with the args.

OK. You didn't show the camera creation. Irrlicht's cameras are really weird.

Err, I don't want to see any more code, though!
