A scripted Visual Script node.
A custom Visual Script node which can be scripted in powerful ways.
Return the node's title.
Return the node's category.
Return the count of input value ports.
Return the specified input port's name.
Return the specified input port's type. See the TYPE_* enum in [@GlobalScope].
Return the amount of output [b]sequence[/b] ports.
Return the specified [b]sequence[/b] output's name.
Return the amount of output value ports.
Return the specified output's name.
Return the specified output's type. See the TYPE_* enum in [@GlobalScope].
Return the custom node's text, which is shown right next to the input [b]sequence[/b] port (if there is none, on the place that is usually taken by it).
Return the size of the custom node's working memory. See [method _step] for more details.
Return whether the custom node has an input [b]sequence[/b] port.
Execute the custom node's logic, returning the index of the output sequence port to use or a [String] when there is an error.

The [code]inputs[/code] array contains the values of the input ports. [code]outputs[/code] is an array whose indices should be set to the respective outputs. The [code]start_mode[/code] is usually [code]START_MODE_BEGIN_SEQUENCE[/code], unless you have used the STEP_* constants. [code]working_mem[/code] is an array which can be used to persist information between runs of the custom node.

When returning, you can mask the returned value with one of the STEP_* constants.
The start mode used the first time when [method _step] is called.
The start mode used when [method _step] is called after coming back from a STEP_PUSH_STACK_BIT.
The start mode used when [method _step] is called after resuming from STEP_YIELD_BIT.
Hint used by [method _step] to tell that control should return to it when there is no other node left to execute. This is used by [VisualScriptCondition] to redirect the sequence to the "Done" port after the true/false branch has finished execution.
Hint used by [method _step] to tell that control should return back, either hitting a previous STEP_PUSH_STACK_BIT or exiting the function.
Hint used by [method _step] to tell that control should stop and exit the function.
Hint used by [method _step] to tell that the function should be yielded. Using this requires you to have at least one working memory slot, which is used for the [VisualScriptFunctionState].
