Set Bundle Contents

Copies the source Item, replacing its bundle contents. Omit the optional content group to clear. Omitted Item to Change reads the current destination Item.

Where to find it

Set Variable → Operations → Choose Operation → Item. Requires Dev access to configure, then a successful compile to activate.

Inputs

Input	Type	Role	Requirement	Default / constraint
Result	Item	Variable binding	Required	Required
Item to Change (omit for destination)	Item	Value	Optional	Omitted; see behavior below
Contents	Item	Value	Optional; ordered plural group	Omitted; see behavior below

Result and behavior

Stores the result in the first configured destination Variable. Its type must match the result and any generic element/key types.

Configuration example

Block: Set Variable → Operations
Operation: Set Bundle Contents
Result: Private Item result
Item to Change (omit for destination): (omit for this example)
Contents: (omit for this example)

Use this as an editor configuration: declare any Variables/collections first and choose real locations/eligible targets for your plot. It is not pasteable source code.

Restrictions and troubleshooting

Item transformations copy their source metadata. For optional Item to Change, omission uses the current destination Item, which must already be assigned. An Item output does not automatically replace a player’s held stack; use a suitable inventory action afterward.
