# bounds_dist proc

Source: https://ref.dm-lang.org/proc/bounds_dist

### Format
> `bounds_dist(Ref, Target)`

### Returns
> The distance, in pixels, between Ref's and Target's bounding boxes.

### Args
- `Ref`: A turf, obj, or mob.
- `Target`: A turf, obj, or mob.


The value returned by bounds_dist() is the number of pixels that the two objects would have to move closer together (if this is even possible, of course) to be touching but not overlapping.

A return value of 12 for instance means the two objects have a gap of 12 pixels between them.

A return value of 0 means the two objects are not overlapping, but their bounding boxes touch.

A return value of -2 means the two objects are overlapping by 2 pixels; they would have to move 2 pixels apart to separate.
