On Craftengine Block Attempt Place Event

Triggers when a player attempts to place a CraftEngine block

EventProvided by Craft Engine

Fires before CraftEngine validates the placement, so it still sees attempts that end up refused. Use the regular place event when you only care about blocks that were actually placed.

Fields

Field	Type	Default	Description
blockId	String	—	The custom block ID that triggers this event (e.g., 'namespace:block_id'). Leave empty for any custom block.
location	Optional<Var<Position>>	—	The location where the block would be placed (optional)
permission	String	—	A permission the player must hold to be allowed to place. Leave empty to skip the check.
allowWhen	List<Criteria>	empty	Facts the player must satisfy to be allowed to place. When unmet, the placement is refused.
cancel	Boolean	true	Whether to stop the placement when the requirements are unmet. Turn off to only fire the triggers.

How to use it

Fires when a player tries to place a block, including when it is refused. Use permission and allowWhen to set requirements: with cancel on, an unmet requirement stops the placement. Turn cancel off to only fire the triggers. An empty permission and an empty allowWhen mean no requirement. The furniture attempt-place and furniture hit events work the same way.
