AllHitsRayResultCallback return order

[SynapticBytes]

I'm just trying to implement an AllHitRayResult callback interface.

After the rayTest, I'm iterating through all of the btAlignedObjectArrays for the collision objects, hit point and normals and reporting them back to the user.

What I have just found out is that it seems the arrays are being populated in a random order. Is that correct? If I do the same rayTest twice in a row, the order in which the hits are being returned is not necessarily closest to furtherest.

Does that sound right? If not, I've got something weird happening.

Thanks.

Well since I couldn't find anything wrong with what I was doing, and lacking advice to the contrary, I've had to just go ahead and implement some sorting and indexing algorithms so I can pass on the results in a sorted manner.

You are correct, the order of the ray contacts are in "random" order.

If you're curious, this is also the case for other Physics engines (like Havok). The physics engine will try to get you the results are quickly as possible, without making assumptions on how the data should be organized.

I just collect all contacts and sort them all at the end.

Thanks for confirming that. At least I now know I don't have redundant sort code int here for nothing.
