first I load map than release map,
than drop device will I get Memory error on drop device.
thanks.
and where is my wrong?

m_gamemap.loadMap(); //like examples 16
//quit loop
m_gamemap.releaseMap();
m_device->drop(); //here is memory error



//release map
void CGameMap::releaseMap()
{
if(m ...

//new flash updata position code
vector3df flash3d = flashbonescenenode->getPosition();
flash3d.Z -= 40.f;
flash3d.X -= 20.f;
flash3d.Y += 5.f;
flash3d.rotateXZBy(-boneNode1->getRotation().X);
flash3d.rotateXYBy(boneNode2->getRotation().Y);
nodemuzzleflash->setPosition(flash3d);

when you load the mesh gun, it is loaded at 0,0,0 coordinates, then create a billboard , position it in front of the gun, then bind the billboard as child to the mesh gun;
then, all the times you move the gun, the billboard will keep relative position to the gun;

thanks,
but useless.
I moved the ...

That`s exactly what I wanted to say- you don`t need to if you setup your parent-child pairs correctly. But as you intend on positioning it manually, for getting world (absolute) positions you can try:

flashbonescenenode->updateAbsolutePosition(); // just to make sure it`s updated. You usually don ...

Once you create the character, weapon and flash nodes and set the correct parents, no additional calls like
vector3df flashpos = flashbonescenenode->getPosition() + weaponnode->getPosition();
nodemuzzleflash->setPosition(flashpos);

will be needed. All this is causing you trouble. When a node ...

I'm sorry, I still can't solve the problem.


How do I calculated flash world coordinates

Has always been there

but
Doesn't work.
flash has been in one place

if I set weaponnode as parents , the nodemuzzleflash can follow my character

ok! what should I do

thx
here it is

/*
* 人物模型节点 character node
*/
node = smgr->addAnimatedMeshSceneNode(Urban_Mesh,0);
node->setPosition(core::vector3df(0,36.f,0)); // Put its feet on the floor.
node->setRotation(core::vector3df(0,180.f,0)); // And turn it towards the camera.
node->setMaterialFlag(EMF_LIGHTING ...

I have a gun muzzle bone node.
But muzzle bone node's position is unchanged, no matter where I move
what should I do?
or how to gets the position of the node for muzzle bone in the whole world coordinates.
thanks very much

thanks Lonesome Ducky and mongoose7 very much

bonenode1->UseAnimationFrom = bonenode2;

Then bonenode1 will have the animation of bonenode2.

I tried.
Such things Bonenode1 animation will be replaced as bonenode2 animation, which did not reach mixed animation

If you can get a joint, that is all you need. See the other thread.

Where should I get a joint. ISkinnedNode or IAnimationSenceNode

You can also load the same mesh twice, the first time with the first animation and the second time with the other animation. Then, go though all the joints of the ...

thanks for your help.
but here I still have problem.
how can I get joint ratation and position from cskinnedmesh with animation. and how to casting this cskinnedmesh.
thanks again
