Collision detection

[lazar.mihai]

Does collision detection only work with bsp maps or can I get it to work with .x files .. and other types of meshes .. ??

I tried to write a program to do it from .x mesh but it didn't work ... any help ?

Works with other formats too.

Managed code example:

Code: Select all

//Add mesh
IAnimatedMesh mesh = smgr.GetMesh("scene.my3d");
ISceneNode meshNode = smgr.AddOctTreeSceneNode(mesh, null, 0, 128);
meshNode.Position = new Vector3D(0, 0, 0);

//Set collision
ITriangleSelector selector = smgr.CreateOctTreeTriangleSelector(mesh.GetMesh(0), meshNode, 128);
ISceneNodeAnimator anim = smgr.CreateCollisionResponseAnimator(selector, camera, new Vector3D(60, 100, 60), new Vector3D(0, 0, 0), new Vector3D(0, 50, 0), 0.0005f);
camera.AddAnimator(anim);

I tried what you said .. but I still can't get it to work .. I think it has something to do with the Managed implementation of Irrlicht.. cause in native code worked fine ... but in .NET it doesn't work ... I can't figure out why ...

Also .. why isn't there a IMeshBuffer written for Irrlicht.NET ? I thought the alpha phase was over and done with .. but I see there are more to work on still ...

HELLO! TRY THIS!


//Add mesh
IAnimatedMesh mesh = smgr.GetMesh("scene.my3d");
ISceneNode meshNode = smgr.AddOctTreeSceneNode(mesh, null, 0, 128);
meshNode.Position = new Vector3D(0, 0, 0);

//Set collision
ITriangleSelector selector = smgr.CreateOctTreeTriangleSelector(mesh.GetMesh(0), meshNode, 128);
ISceneNodeAnimator anim = smgr.CreateCollisionResponseAnimator(selector, camera, new Vector3D(1, 1, 1), new Vector3D(0, 0, 0), new Vector3D(0, 1, 0), 0.0005f);
camera.AddAnimator(anim);



I had the same problem and i have solve this way!you must be care ful with the parameters of CreateCollisionResponseAnimator.
