vvvv-custom-nodes

To create a custom C# node for vvvv gamma, write a class using the `[ProcessNode]` attribute and define its `Update` method with `out` parameters first, followed by value inputs. This structure enables stateful node logic.

The `[ProcessNode]` pattern in vvvv gamma is an attribute used to define stateful custom C# nodes. It requires implementing an `Update` method to process input pins and generate outputs continuously across evaluation frames.

You detect input changes in a vvvv gamma custom node by implementing change detection logic within your C# code. This approach ensures efficient recomputation by only updating outputs when specific input pin values are modified.

Yes, you can access core services like `IFrameClock`, `NodeContext`, and `Game` inside custom vvvv gamma nodes. This service consumption allows your C# code to integrate tightly with the visual programming environment's timing and context.

Output patterns for vvvv gamma C# nodes include return-based outputs and rising edge detection. You define these by configuring `out` parameters in the `Update` method to control how data flows to downstream pins.

To manage memory performance in the vvvv gamma Update loop, structure your C# node to avoid allocating new objects during each frame evaluation. Efficient pin configuration and change detection minimize garbage collection overhead.
