I did a little modification so that it works with arrow keys
There was also a bug in the condition before your getdir(speed.x,speed.y)
You had &&'d it, and so it wouldn't update the direction if you were only moving one way. Just replace && with || like I did here.
EDIT: I changed a lot of the code. There were a lot of problems, I tested it with a friend and when we collided, we were stuck on each other! Now you can get out of walls and not fly through them if moving fast (only does the save check if you are stuck in a wall, otherwise you can still have a high speed set and the raytrace won't skip the wall)
LAST EDIT:
I fixed my own bugs and made it work almost perfectly! A saveCheck is set and overrides the speeds to try and get you out of the wall. Works perfectly for me
If you want to use it for mouse still, just uncomment the mouse lines I took out.

I'll be using this I think.
