onwall2() and onwallpath() : return useful info?
 

I think these functions would be even more useful if they returned intersect coordinates. I'm not a coder, so I'm not exactly sure how this could be achieved, or if it's even possible(or useful), so if actual coders want to chime in please do. The more constructive, the better. Right now the usefulness of these functions are often lost because you end up having to run precision loops to get the most out of these after the actual collision.

I feel like that could potentially break things, perhaps it could store the point where it was on the wall, and then make that value accessible via:

getwallcollision()

Would be nice if we could specify an array of tiletypes which should block.
