"phy ray cast" and "phy ray cast all shapes" appear to be both returning the lowest numbered object the ray collides with. For instance, if you cast a ray as so:



This happens with both.

phy ray cast closest shape seems to return no collisions of any sort at all, ever, period, end of story. I'm not the only one to report this happening either. I've found posts from even Dark Coder himself reporting this problem with "phy ray cast closest shape"

Everything I needed to know about trigonometry, I learned by becoming a game programmer.

Lucy are you cast your ray in this order?




this is how the demo is doing it.

Actually I think I corrected myself a few posts later, I don't recall the exact issue but one of the two commands takes a unit vector direction and the other takes a world-space position for the ray-end, I think. So it was more of the documentation/commands being wildly different rather than them not working.

I'm using DP 1.05.

HowDo, that's precisely how I'm doing it.

DC, that's exactly what I've been doing. I've been casting with world space coords and with normalized direction vectors, as noted in my original post.

However, phy ray cast closest shape() is NOT returning properly. I've cast with both a normalized vector (as works with phy ray cast all shapes()) and with a world coordinate vector (as works with phy ray cast()) and phy ray cast closest shape() does not work.

At any rate, I emailed Mike Johnson about the problem and he's confirmed that something funky is going on with ray casting. It's not working the way he remembers it and says he's going to try to fix it.
