Hi. I was making simple script to randomly set translation of my object but I wanted to improve it. I was looking for function sth like GetIdOfSelectedObject (or sth familiar) but I couldn't see anything like this.
I would like to include to my script to automatically get ID of selected object.
Greetings Pyrol

If you open Giants Editor and select Window - Script Editor there you will find a script called Object Info

If I understand you correctly then is your selected object the id. For example you have select a brush then the value is the Id. So you can use this variable directly for setWorldRotation or so.

But this works not for all. The best way is it when you post your code or explain your plan better (which object,...).

@Colin I have not any scripts only 'dirtutil' and 'editorutils'

@Kevin I'd like to select an object and script should get info about(ID) which object in scenegraph I've selected, so I don't must change it to another every time

this is simple script but isn't working as I want but sill good.
Also I'd like to know how can I save object translation using function getTranslation - I can just take one coordinate (I thought about table but idk how to read every of these 3 values )

Sorry my mistake that script is not part of Giants 7.1 but if you download a copy of Giants 6.0.5 ( its in the script folder of that editor. I transferred all the relevant scripts when I upgraded to 7.1

Bartek Perkowski (Pyrol) 17.02.2018 14:21
@Colin Even if I installed 6.0.5 I have not any scripts there, also I checked local folder (my scripts are there) but I've question about how to insert every value using "getTranslation" to table because here I'm ONLY able to get first value
(in C++ I could do like to make these values one string and in loop I would split it into X Y Z)

Here is the Object Info script

That script doesn't work. I tried selecting a single object but it says: Error: -- Author:LKXstudios...(15) : attempt to call global 'getClassName' (a nil value)
