This snippet is written for an adapter of Irrlicht to argortha
Now, I want to write another adapter for DirectX
Just wondering the code underneath which specifies a lineCollision, it is to me a
line, but when passing to getCollisionPoint, it is a ray.
Can I treat them both the same?
I would use the
D3DXboxBoundProbe function

Rather be

D3DXIntersect instead, sorry

irr::core::line3df lineCollision(actorPos, IrrVector3Adapter(io_actor->getPosition() + in_displacement));

irr::core::vector3df outColl;
irr::core::triangle3df outTri;

if (mScmgr->getSceneCollisionManager()->getCollisionPoint(lineCollision, mSelector, outColl, outTri))

Sorry, back in here again.
I find that D3DXIntersect doesn't suit my needs.
That requires a ID3DXMesh and a Line Segment intersection test.
Just wondering what can replace the D3DXIntersect function to
test between ID3DXMesh and a Line Segment (a line that *does* have
an endpoint)
Thanks

Hi there. You may be able to use D3DXIntersect by converting the line segment to a ray and then checking the pDist returned from the D3DXIntersect. If PDist is greater then the Lines length not a collision.

I came up with this solution too, but just unsure if it works or not,

thanks for confirmation.
