distance to wall in given direction
 

How can I calculate the distance to the wall from a given point and in a specified direction?

(e.g. wallDist gives the nearest distance to the wall)

Thanks

Sorry to resurrect an old post, but I'm wondering if you ever solved this problem? I've been trying to do the same thing but the algorithms I've used are much too slow.

Unfortunately no. I managed to do without it in the end.

Ah, that's too bad. Thanks for the quick reply though!
