How to move an object without landing on top of the object?

[jakeonthelake]

I am having trouble figuring out how to move an object to a specific target without it landing on the target...

I would use proximity or collision detection to find out how close it is, then move it away.

Or something like this:

(object) move toward (other object) distance = (distance to other object - objects width) - other objects width
