Hello,
So, I’m using a sprite that is a tree top in order to decorate my environment.
I would like to know if there is a way to code something in the inspector so that when click and drag the sprite, it will randomize the size and color (previously defined values), so that I dont have to copy them then change those settings manually.
(I dont want to do that at run time! It is only a “builder tool”)
You can do that with a custom editor for your script. I’m not sure you can call a method upon drag/drop (probably can), but you can easily create a button to randomize the values via script. I haven’t worked with custom editors much so will defer to others for advice 
You can really do all kinds of whacky things at editor time… pretty much almost everything you can do at runtime.
For instance you could put a single tree sprite somewhere then have a button to “spread a bunch of these randomly around here” or “randomly in this rectangular area,” then tune them by hand and press save on the scene.
You can do this with OnValidate() functions I believe, or just do it by selecting stuff in scene and running your code. It can be as simple as decorating a static function with [MenuItem(“Do it”)] and then iterating the Selected property and doing your thing.
Okay, will take a look at that. Thanks!
