Some old games used to do this. They'd store a mask of impassable screenzones in memory. You could do this with memblocks and a bitmap. Then get the pixel color using your x/y coords and vector to see if it's impassable.

you can mask the impassible area's using say white and the passable area's black.

You'd then use something like

IF POINT(x,y)<>RGB(255,255,255)
PRINT "Free!"
ELSE
PRINT "Blocked!"
ENDIF

That's one way of doing it.
