Arrays are ordered lists of Objects. See the guide on arrays here for a more detailed introduction.
Add an object to the array by sending a signal on the Add input and providing the Id of the object to add on the Item Id input. Same goes fore Remove to remove an object from the array.
Items
This input sets the source of the array, this input is of array type, Noodl.Array. You can for instance forward the content of a Static Array node using this input. The content of the source array will be copied to this array by default and any changes to the source array will also be copied automatically. You can control this by making a signal connection to Set, in that case the items, i.e. content of the source array, will only be copied when a signal is received on Set.
Id
This is the Id of the array, it works similair to objects and variables. It specifies the array that this node will act on via it's Id. All Array nodes with the same Id will refer to the same array of objects.
Item Id
The item id to add or remove. Used in conjunction with the Add or Remove inputs.
Add
Signal to add the Object with the id specified with the Item Id input to this Array.
Remove
Signal to remove the Object with the id specified with the Item Id input from this Array.
Clear
Signal to remove all Objects in the Array
Fetch
Normally when Id is set, the items and count outputs are immediately updated with the content of the array referenced by the Id. If you want to control how the data is updated you can connect to the Fetch signal input. Then you need to explictly send a signal here for the Array node to fetch the data. Before an array have been fetched none of the modify and set operations or source items will have any affect.
New
Sending a signal to this input will generate a new empty array with a unique Id and the Created output signal will be emitted. If there is a connection to the Items input the content of that array will be copied.
Id
The Id for this Array.
Items
This is an output that can be connected to others that can take Array inputs, such as the For Each node. It will hold an Noodl.Array type.
Count
The number of items in the Array.
Modified
A signal triggered when any of the Add, Remove, Clear actions above is completed.
Changed
This signal is triggered when the content of the array is changed, either by an action on this node or by some other node in the graph that operates on the same array Id.
Fetched
Triggered when a Fetch action has been performed and the data is ready.
Created
A signal is emitted here when a new array has been created and is ready as a result of the New action.
Stored
A signal emitted after the content of the array have been updated as a result of a Set input signal.
