Really useful script for getting the distance between two objects in either its Vector 3, X, Y, or Z
You can also get the negative distance if the object is behind or in front of the target. I use it a ton so get it while its hot!

Awesome, thanks! :)

Hi,
Great. Don't forget there is a GetDistance2 (https://github.com/jeanfabre/PlayMakerCustomActions_U3/blob/master/Assets/PlayMaker%20Custom%20Actions/GameObject/GetDistance2.cs) custom action as well, but your action goes further, so it's a nice addition.
I have made it available on the Ecosystem (https://hutonggames.fogbugz.com/default.asp?W1181).
Bye,
Jean

Hey Jean, thanks! This is always my worry that there is an action that already does what I plan on making but I don't know the name of it :P
-
Hi,
no worries! your action brings more on the table, it's totally fine, and even if it did not, we all get that, I sometime write an action twice because I forgot I did it before... It's a problem that I am not sure how to solve, apart from searching on the forum and ecosystem prior doing it, but then depending on the wording, it can be missed...
any idea on how to solve this is welcome :)
Bye,
Jean

Hey Jean, can I have permission to change my scripts on Ecosystem?
There was a hi jink with this one that needs fixing.
Please everyone use this updated version which has the proper settings for the Negative values.

Hi,
Changes is up on the Ecosystem.
Actually, for Unity 4 + actions, the Ecosystem feeds from a Github public repository (https://github.com/jeanfabre/PlayMakerCustomActions_U4), so simply clone this on your computer, edit the script and push back and you are done :)
Bye,
Jean
