In this little vvvv tutorial I will talk about the 2 most common nodes to create a bang: the Change and the TogEdge. A Change node will give a bang on the slightest input change. A TogEdge nodes will give a bang when a value either goes from 0 to 1, or UpEdge, or if a value goes from 1 to 0, or DownEdge.
I will also show you a way to lower the framerate, using the mainloop node, and how to detect mouse clicks inside the renderer using the Mouse (System Windows) node.
Once you understand these 2 nodes, you got some powerful tools to work with bangs, in the next few lessons I will be dealing with some nodes that are using bangs to do stuff.
