Ok so this system is good for a few things.
click the cube, it’s now in your ‘Hand’
now own[‘Tank’][‘Holding’] = the game object your holding,
This gives you access to trigger logic in the object, (this is how I use modular weapons in wrectified)
The object can be moved, (with moving the player) and placed elsewhere
The object can be converted into a string and stored in a container (inventory or crafting table or?)
