I tried to implement collsion detection into the special effects tutorial that is provided on the main website. However its not really detecting my collsions :/. It however has a like the triangle in the view of the camera in front of me becomes highlighted with a red boarder. Yet I still can go though the walls maybe im missing somthing here 0.o? I haven't ever implemented 3d collsion detection and im not quite sure how to make it respond and detect a collision with the camera/player.

Did you add your main triangle selector to the camera with an animator? Kinda like this:

Code: Select all

anim = smgr->createCollisionResponseAnimator(mainTriangleSelector, Camera, core::vector3df(30,50,30), core::vector3df(0,0,0), 100.0f, core::vector3df(0,20,0));
Camera->addAnimator(anim);
anim->drop();

scene::ISceneNodeAnimator* scen_anmi = smgr->createCollisionResponseAnimator(
selector, node, core::vector3df(30,50,30),
core::vector3df(0,-100,0), 100.0f,
core::vector3df(0,50,0));
// camera->addAnimator(scen_anmi);
scen_anmi->drop();

is what i did i commented out the camera add animator cuz it didnt seem to work :/

it caused game to crash

uh uh... thats what adds the collision detection to the camera. Uncomment it and it should work. If it's crashing then the problem is somewhere in making the map's triangle selector.

Hi

Correct me if I am wrong but I think it has to be
scene::ISceneNodeAnimator* scen_anmi = smgr->createCollisionResponseAnimator(selector, camera, ...
instead of (selector, node, ...

Cheers

Hi

the createCollisionResponseAnimator has another value at the end (slidingValue)

f32 sliding = 0.0005f;

smgr->createCollisionResponseAnimator(selector, camera, core::vector3df(30, 35, 30),
core::vector3df(0,-10,0), 100.0f, core::vector3df(0, 17, 0), sliding);

Try with different values, not easy to find the right one (at least for me, still trying).

Cheers
