Hi all,
first of all let me show you the problems:
Here is collision detect/block path from one side of Arc
1)
And here the same thing but in other side of Arc.
2)
And now my steps for accomplish the block path:
1)Compute boundingbox with D3DXComputeBoundingBox only at initialization of each entitis.
2)Everyframe I trasform the Max and Min point to world space with:
//=================================
//Bounding box coordinate in world space
D3DXVec3TransformCoord( &mBBoxWorld.maxPt, &mBBox.maxPt, &mWorldMat );
D3DXVec3TransformCoord( &mBBoxWorld.minPt, &mBBox.minPt, &mWorldMat );
3)Everyframe check aabb collision, if any:
3.1)
D3DXVec3TransformCoord( &RayPos, &RayPos, &worldInvTrans );
D3DXVec3TransformNormal( &RayDir, dir, &worldInvTrans );
HR(D3DXIntersect((*it)->getMesh(),&RayPos,&RayDir,&hit,&FaceIndex, &u, &v, &Dist,&allhits,&numHits));
If hit and if dist<Min_distance I block the movement.
Now the first question:
1)Is this the right way ? The things go quite good except for collision show in figure 2.
2)The computed boundingbox is computed( :) ) when mesh is not animated, so like you can see in figure 1 the aabb is smaller then model.
(The black cross is just a little mesh positioned in mBBoxWorld.maxPt)
3)And for figure 2 what do you think is the problem? Why bounding box ar so small for arc ?
Bye and thanks for you time;)
