Help with meshes
Hi, well, I am trying to figure out meshes, parts, groups and the like, especially selecting them. I can do this with Phys_Hit easily enough, but I am planning a lot of meshes with simple physics if any, but need to gain the hit object and pos of the hit. Sweep seems like the answer, but I'm a bit lost. I edited lesson 14 - Mesh - Armor Rendering as below...with comments where I edited. Thanks, Rigs.
Code:

void update()
{
// set skeleton animation
