How to do a collision test - urgent please?

[prchakal]

Hi,

Im new on IrrLicht and i read all the tutorials and examples, but i dont understand how i can check/test the colission between the map and the player(mesh), can anyone explain based on my code below:

Code: Select all

//map load
device->getFileSystem()->addZipFileArchive("./dados/mapas/mapa1.pk3");
IAnimatedMesh *map = smgr->getMesh("20kdm2.bsp");
ISceneNode *map_node = smgr->addOctTreeSceneNode(map->getMesh(0));

map_node->setPosition(vector3df(0,0,0));

//player load
//carrega modelo
IAnimatedMesh* mesh = smgr->getMesh("./dados/modelos/knight.md2");

//adiciona node com o modelo na cena
IAnimatedMeshSceneNode* jogador = smgr->addAnimatedMeshSceneNode( mesh );

//define propriedades do modelo
if (jogador)
{
    jogador->setPosition(core::vector3df(0,185.0f,0));
    jogador->setMaterialFlag(EMF_LIGHTING, false);
    jogador->setMaterialTexture( 0, driver->getTexture("./dados/modelos/knight.pcx") );
    jogador->setRotation(core::vector3df(0,0,0));
}

And my other question is, how i can hold my player(mesh) on the map floor without use physic library?

OMG! As i say, im already read, but dont understand.

i read all the tutorials and examples

And the tutorial dont explain with my situation.

If i post here is because i dont understand.

Can anyone explain the collision on my situation?

then you should study C++ first.

Again o.o

I know C++ but i dont understand the collison method

Thanks for help.

shoot a ray from your model downwards and check if it's intersect with a triangle. it's all explained in the tutorial page. if you really understand then you should be able to udnerstand the tutorial as well. descriptions and even the sample codes are there. what else you want.

Im done it, not hard.

I always listen about the community of Irrlicht that help everyone, but i think that it is a lie.

But thanks, God bless you!

Do you know any website that i can download mapa ms3d/3ds for free?

Plain map to do tests with grass texture, because im horrible to model and my map is small and without texture

Like this: http://www.turbosquid.com/3d-models/3d- ... ene/418481

people kept posting the same questions and we kept answering it over and over again. you have to learn to search on the forum there are tons of answers in the older topics.

Hi, i dont know why, but the player(mesh) is a little far from the floor, what i can do to it stay/walk more near possible from the floor?

The gravity is normal and the player is walking normal, but a little far from the floor.

change the radius of the ellipsoid in your createCollisionResponseAnimator() (again, it's covered in the collision tutorial)

Hi,

Thanks, but the problem is not this, i change like the tutorial explain, but nothing happen, so i change the map and the problem is solved, i think that is my map that i take on the net.

First of all, we are not here to do your "homework" but to help if you have problems.
Now, you give us a link in some foreign language that most of us can't even understand, you don't even show your code or anything...
How are we supposed to help you ?

And now you expect help ?
