Property	Value
Native Name	`ADD_STATE_BAG_CHANGE_HANDLER`
Hash	`0x5BA35AAF`
Return Type	`int`
API Set	`shared`
Parameters	`keyFilter` (char), `bagFilter` (char), `handler` (func)

Description: Adds a handler for changes to a state bag.

The function called expects to match the following signature:

function StateBagChangeHandler(bagName: string, key: string, value: any, reserved: number, replicated: boolean);

bagName: The internal bag ID for the state bag which changed. This is usually player:Source, entity:NetID or localEntity:Handle.
key: The changed key.
value: The new value stored at key. The old value is still stored in the state bag at the time this callback executes.
reserved: Currently unused.
replicated: Whether the set is meant to be replicated.

At this time, the change handler can't opt to reject changes.

If bagName refers to an entity, use GET_ENTITY_FROM_STATE_BAG_NAME to get the entity handle If bagName refers to a player, use GET_PLAYER_FROM_STATE_BAG_NAME to get the player handle

Parameters

keyFilter (char*) — The key to check for, or null for no filter.
bagFilter (char*) — The bag ID to check for such as entity:65535, or null for no filter.
handler (func) — The handler function.

Examples

AddStateBagChangeHandler("blockTasks", null, async (bagName, key, value /* boolean */) => {
    let entity = GetEntityFromStateBagName(bagName);
    // Whoops, we don't have a valid entity!
    if (entity === 0) return;
    // We don't want to freeze the entity position if the entity collision hasn't loaded yet
    while (!HasCollisionLoadedAroundEntity(entity)) {
        // The entity went out of our scope before the collision loaded
        if (!DoesEntityExist(entity)) return;
        await Delay(250);
    }
    SetEntityInvincible(entity, value)
    FreezeEntityPosition(entity, value)
    TaskSetBlockingOfNonTemporaryEvents(entity, value)
})
