How can i make a SceneNode moves above a Terrain!

[mmh771]

I've created a terrain object and a car object using 3dMax, and converted them into my3d, and load them separately in Irrlicht Scene.

The car named: carNode, and the terrain named: terrainNode, and also created a FPS camera in Irrlicht named: cameraNode.

Now the cameraNode collide with both terrianNode and CarNode, and i've also created a collision response animator between the car and the terrain.

But what i need now is "HOW to make the car moves ABOVE the terrain?!" ... the path is not critical here .. i just want it to move above it just like in real world, when it face a hill; it will go up, when i face a slope; it will go down.

Any help please! ....

I think what you need is the NEWTON physics engine - programming vehicle physics by yourself will be VERY hard....

Am not talking about a pyhsics here ... i just want to know how to move a box over a terrain ....

You just use the collision response when the car collides with the terrain it moves the car up. Check out the terrain example which is part of Irrlicht

For simple use,U can just get the vertical position "iGroundPos" of the Terrian at every beginning of a frame,&keep a certain distance from "iGroundPos".

MoonShine721,
Will i still be able to use the "iGroundPos" even if i am not using an Irrlicht Terrain! .... as i said above the terrain i am using is actually my3d object ... built with 3Dmax ....

and would you PLEASE post some code just to explian the use of that function (iGroundPos )

Ah, I thought you want the car to lean back when it goes up a hill and so on... If you just want the car to move above the terrain, just use the collisionResponseAnimator.

EDIT: I think the ResponseAnimator is a lot easier than dealing with the ground pos and so on - especially if your terrain is a model.
