onwall3()
 

Requesting the following:

Basically the usual onwall checks, but in the specified circle. Would be pretty useful (: Circles for the win!

I prefer my suggestion of polygonal check :)

Well, creating a circle with a polygon is also somewhat annoying, so maybe both?

Not really. A polygon would be widely more flexible, and given it can create what you're asking by just doing a small calculation, I'd say it's the better option. Either way, Stefan doesn't seem too interested in this stuff.

So, something like this Dusty? (Red lines is the poly check while the red tiles is what tiles that are returned)

And, tried the onwallpath() function? onwallpath(x, y, w, h, dx, dy);

Nah, my idea was to check walls within a polygon(just like used in showpoly), and it would also return the points where the polygon intersects the wall. Like so...

Yellow would be the coordinates returned.

Hmm.. interesting

I'd rather see this be implemented. Either would be nice, though.
