[Q] 2. Child Camera with loaded Meshes

[MetaMapper]

Hi there,
i have a question... i made a hud with tutorial 6 (2d) so far so good... now i want a weapon too, but not as a pic (.bmp/2d hud)! i want to load a weapon model...
Well i read some threads and found out that this is possible with a
"second (i m using a FPS camera) child camera with a loded mesh"...?

Well... i ve never coded child stuff (dunno what this means)... could u help
me?

This should be fairly easy, and irrlicht makes adding nodes to others as children very simple.

What you need to do is create a pointer to your camera, then load your model, and set it's parent to the camera.

Here's some sudo-code

Code: Select all

scene::ICameraSceneNode* camera = smgr->getActiveCamera();
IAnimatedMesh* mesh = smgr->getMesh("Filenameofmesh");
scene::IAnimatedMeshSceneNode* node = smgr->addAnimatedMeshSceneNode(mesh->getMesh(0),camera <--This is the parent);

Then just add a texture and treat the node as normal.

So if i understand right...

this is my parent-cam (my main FPS cam):

Code: Select all

scene::ICameraSceneNode* camera;

camera = smgr->addCameraSceneNodeFPS(0, 100.0f, 280, -1, keyMap, 9, false, 0.35);

camera->setPosition(core::vector3df(-100,50,-150));

and i need to make a child cam with ur code:

Code: Select all

camera = smgr->getActiveCamera();
IAnimatedMesh* mesh = smgr->getMesh("Filenameofmesh");
scene::IAnimatedMeshSceneNode* node = smgr->addAnimatedMeshSceneNode(mesh->getMesh(0),camera); 

is this correct?
if yeah, there comes an error...
it says that it cant convert parameter 1 (imesh) to parameter 2
(animatedmesh) or something like this... it occures in this line:

"smgr->addAnimatedMeshSceneNode(mesh->getMesh(0),camera);"

greetz, hope 4 help

If you want to add an *Animated*MeshSceneNode you habe to use an animated mesh as the first parameter. Don't use getMesh(0). Or add an IMeshSceneNode...

[MetaMapper]

u mean:

Code: Select all

camera = smgr->getActiveCamera();
IAnimatedMesh* mesh;
scene::IAnimatedMeshSceneNode* node = smgr->addAnimatedMeshSceneNode("PathofModel" ,camera); 

??

[hybrid]

No. Use smgr->addAnimatedMeshSceneNode(mesh, camera) with mesh containing the animated mesh as in your first example. I said don't use getMesh(0); the getMesh("filename") is ok.

thx =)...
um... my last question is... how can i fix this cild cam (node) in front of the main fps-cam?

greetz

[MetaMapper]

can i fix it with this lines:

Code: Select all

           node->setPosition(vector3df(0, 0, 0));
           node->setScale(vector3df(1, 1, 1)); 

?

[hybrid]

No, because those are the default values. You have to play with the position until it happens to have the correct place. Just remember that positive z is into the plane (further away from the cam) and positive y is up (positive x is to the right, but one's used to that).

[MetaMapper]

Yea i know that i need to change the values first but are the commands right:

Code: Select all

           node->setPosition(vector3df(x, x, x));
           node->setScale(vector3df(x, x, x)); 

i mean setposition and setscanle x_x'
