I have an object, it is following another object.

Is it possible to check if the next position it will move is collision free?

(I am assuming this would be in terms of direction?)

I'm not sure, but since nothing is executed simultaneously in programming (unless you start playing about with multithreading, but let's not go there) you could just check at the start of the procedure to see if there currently IS a collision, and if so, go back to the previous position. The end result will be like it never moved, because you'll catch it before the new and invalid position has a chance to interact.
