Moving model

Guest · Post by **Guest** » Fri Sep 12, 2003 3:33 pm

I would like it to run when I move the "model" but when it does nothing, i would like to have the "stand up" animation How can i do that ?

Simply use the setMD2Animation method for your MD2 scenenode with the EMAT_STAND enum as parameter for the standing animation, or EMAT_RUN for the running animation.

I added this piece of code :

scene::ISceneNode* noeud_perso = 0;

class MyEventReceiver : public IEventReceiver
{
public:
virtual bool OnEvent(SEvent event)
{

if (noeud_perso != 0 && event.EventType == irr::EET_KEY_INPUT_EVENT&&
!event.KeyInput.PressedDown)
{
switch(event.KeyInput.Key)
{
case KEY_KEY_W:
case KEY_KEY_S:
{
core::vector3df v = noeud_perso->getRotation();
v.Y += event.KeyInput.Key == KEY_KEY_W ? 20.0f : -20.0f;

noeud_perso->setRotation(v);
}

return true;

}
}

if (camera)
return camera->OnEvent(event);

return false;
}
};

But this don't affect the rotation of my model in this code :

scene::IAnimatedMeshSceneNode* noeud_perso = 0;
material.Texture1 = driver->getTexture("../../media/sydney.bmp");
material.Lighting = true;

scene::IAnimatedMesh* personnage2 = smgr->getMesh("../../media/sydney.md2");
if (personnage2)
{
noeud_perso = smgr->addAnimatedMeshSceneNode(personnage2);
noeud_perso->setPosition(core::vector3df(-40,-10,0));
noeud_perso->setAnimationSpeed(1);
noeud_perso->setMD2Animation(scene::EMAT_STAND);
noeud_perso->getMaterial(0) = material;
}

Have you got an solution ?

Sam.

It worked for me perfectly. Note that due to the !event.KeyInput.PressedDown condition in the code, the rotation code is only executed when you RELEASE the W/S keys. Maybe that's the "problem"?

In the case you want to keep keyboard down during moving, use this condition instead :

Code: Select all

if (node != 0 && event.EventType == EET_KEY_INPUT_EVENT)

I remove this code : !event.KeyInput.PressedDown
Always the same problem. Impossible to move the model.

Err ... I guess this was some kind of misunderstanding. The code you showed in your first post obviously does, what I told you (?) about object rotation in another thread - it rotates the model around the Y axis. Rotation is not translation. To translate your object, simply add a vector to the node position, where direction and length of the vector define the change of the position.

Cheers.

But you re right !

If i can move the model, i can rotate it.
The problem is : I can not rotate or move with the keyboard my model.

This is my solution :

scene::IAnimatedMeshSceneNode* model2 = 0;

public:
virtual bool OnEvent(SEvent event)
{

if (model2 != 0 && event.EventType == irr::EET_KEY_INPUT_EVENT )
{
switch(event.KeyInput.Key)
{
case KEY_KEY_W:
case KEY_KEY_S:
{
core::vector3df v = model2->getRotation();
v.Y += event.KeyInput.Key == KEY_KEY_W ? 20.0f : -20.0f;

model2->setRotation(v);
}

return true;

}
}

if (camera)
return camera->OnEvent(event);

return false;
}
};

{
model2->setPosition(core::vector3df(-70,-15,-60));
