Why use a convex collision shape?

[scot.mcpherson]

I don’t understand why a convex collision shape has been chosen for our animated hazard.

A primitive is more performant.

Convex and concave collisionshapes are usually used to create a collision shape for more complicated meshes that aren’t easily represented with one or even just a few primitives.

So…why are we guided to choose a convex shape here for a simple box?

Thanks

hi,

I think its shown here, as with a couple of other lecture topics, as an alternative way of doing it.

the simplified convex collision sibling, in the case of a cube, thankfully gives the exact same collision shape if we were to add a primitive box shape for this.

i think the big differerence would come, as you mentioned, with irregular or non mathematical collision geometry where this option would create a boundary convex mesh.

not 100% sure, but that was my take away from it.
