Here is some .dat files for 2 objects that do just that, basically if you have the item like the box and you haven't placed it yet then it gives you a flag bool that says you've placed it and takes the item. The green one only shows when the flag is set to false, and the real box when its true
#Object placement
hazy spear
austere goblet
NPC events

@narrow glacier this is done throught object conditions and interractability
The object you have to pickup will only display if a certain condition is met, this object can be interacted with and will break the condition (making it disappear) and rewarding the player with a flag
This flag will display a semi transparent object (the placeholder) via conditions, and it can be interacted with to break its own condition and reward a flag, showing the final object
You can use a single flag short for everything
Flag=0 nothing
Flag=1 pickable object displayed
Flag=2 placeholder displayed
Flag=3 Final object displayed
zinc latch
Yes, by replacing the flag with an item condition
You can add Condition_x_Reset if you want the item to be taken
zinc latch
No unfortunately
