How to get closest 3d object?

jbskaggs

In my 2d game I could use go thru an array of obects and use distance_to and get the closest enemy marble easily enough.

In 3d I don't really understand the reaction.

nearest_marble.transform.origin.distance_to(transform.origin) < 2.5:

When I print this terminal- for most of my pathfollow it gives one number counting down as it gets closer- but then it appears to give me 2 numbers. One within my range and a 2nd above my range. Which causes issues.

Could some explain how 3d distance_to works or the easiest way I can get closest enemy?

distance_to works fine, but transform.origin is probably not the value you want to use. Probably marble.translation is what you want.

Thank you I shall try :)

If both nodes are siblings (with the same parent) the distance_to comparing their translation vector3s is going to work as you'd expect. If not you need to get their global translation; I use nodeName.global_transform.origin for that.

That made things simpler, My issue turned out to be the Root scene had been accidentally added to my array causing my tower to misfire at an enemy that was not there. Fixed it now.
