A node group allows you to create a folder that contains multiple NodeBlock. Once connected all blocks can be selected or deselected all at once. Additionally, a unique color can be specified to visually identify all NodeBlock that belongs to the same group inside the editor.

Functions

Name	Description
`AddNodeBlock`	Attach a new NodeBlock to the active NodeGroup.
Declaration bool AddNodeBlock( NodeBlock nodeblock ) Parameters* `nodeblock`: A valid NodeBlock reference. Return Value `true` if the NodeBlock have been connected successfully; `false` if the reference is invalid or if it does not belong to the same NodeTree.
`GetNodeBlockAt`	Retrieve a NodeBlock reference from the current NodeGroup using its index as key.
Declaration NodeBlock GetNodeBlockAt( unsigned char index ) Parameters* `index`: Index within the NodeGroup of the NodeBlock to retrieve. Return Value A valid NodeBlock reference; else return `nil` if the index is out of bounds.
`GetNodeBlockIndex`	Get the internal index of a NodeBlock stored in the current NodeGroup.
Declaration int GetNodeBlockIndex( const NodeBlock nodeblock ) Parameters* `nodeblock`: A valid NodeBlock reference. Return Value `-1` if the `nodeblock` reference cannot be found in the current NodeGroup; else return the internal index of the NodeBlock maintained by the NodeGroup.
`RemoveNodeBlock`	Disconnect a NodeBlock from the current NodeGroup.
Declaration bool RemoveNodeBlock( NodeBlock nodeblock ) Parameters* `nodeblock`: The NodeBlock reference to disconnect. Return Value `true` on sucess; `false` if the NodeBlock reference is inexistent.
`ConnectLink`	Create a new NodeInput and attach it to the current NodeGroup.
Declaration bool RemoveNodeBlockAt( int index ) Parameters `index`: Internal index of the NodeBlock to disconnect. Return Value `true` on success; return `false` if the index is invalid.
`IsSelected`	Determine if all NodeBlock associated to the active NodeGroup are selected.
Declaration bool IsSelected( void ) Parameters `nodeblock`: The NodeBlock reference to disconnect. Return Value `true` if all NodeBlock references are marked as selected; else return `false`.
