Property Change

This is an advanced but extremely powerful event. It doesn't trigger based on a world interaction, but on a change in your game's logic. It fires whenever a specified Property is modified.

Action Values

• Player: The player whose property changed (if it's a Player-held property).
• Property: The property that changed.
• Old Value: The value of the property before the change.
• New Value: The value of the property after the change.

Event Configuration

• Property: You must select the specific property you want this event to listen to.

Use Cases

• The foundation of reactive game systems.
• Automatically checking for a win condition every time a player's score changes.
• Updating a scoreboard or hologram instantly when a property is modified.
• Triggering a special effect when a player's health property drops below a certain threshold.
