[need an advice] How to set the position of a mesh

Konstantin · Post by **Konstantin** » Sun May 27, 2007 8:54 pm

Hi,

I've a problem with changing the position of meshes. In the tutorials there's allways used ''SetPosition()''.
But when i modify some parameters of that function, nothing changes.(?)

Is that the right function? Or is there another way to set the position of a mesh?

Thank you for answers and advices.

setPosition acts on SceneNodes. A Mesh does not have a position.

make ur scenenode first. ex:

Code: Select all

 
ISceneNode* wutevernode = loading ur mesh;

wutevernode->getposition(core::vector3df(0.0f,0.0f,0.0f); //vector3df(x,y,z)

Thanks for that tip but it doesn't

It only says
'getposition': Isn't a element of 'irr::scene::ISceneNode'

What's my mistake? Please help.

getposition is wrong written. it has to be getPosition.

No, it has to be setPosition(core::vector3df(x,y,z));

Hybrid? Would you give me a little example pls?

PS: Is there a RTS-Camera in the engine?

I've made the code like this:

Code: Select all

       scene::IAnimatedMesh* mesh = smgr->getMesh(
		"../../media/beast.x");
	
	scene::IAnimatedMeshSceneNode* anode = 0;
	anode = smgr->addAnimatedMeshSceneNode(mesh);
	anode->setPosition(core::vector3df(0,0,0));
	anode->setAnimationSpeed(20);
	anode->setScale(core::vector3df(100,100,100));
	anode->setMaterialFlag(video::EMF_NORMALIZE_NORMALS,true);

But even if i modify the 'setPosition'-Values to 1000,1000,1000 the mesh stays there where it is now.(?)

maybe because of large scale 1000 deosnot seem to move.. it happened to me once try larger numbers like 1111989

Thanks! Now everything works!

Yes, you might not notice a move of 1000 units if your mesh is 100*original size which is probably much larger than 10 units. Your code should work (although you might have to call updateAbsolutePosition of you use Irrlicht 1.2 or earlier just after setting the position).
