# Controlling flows

The AFX system includes multiple nodes that you can use to control flows. This includes conditional branching, looping, and one time activation.

For example, if you wanted an object to begin moving, and to continue moving, after a collision took place, you could use a `Toggle` node.

In this example, the `Start` node sets the initial state of the `Toggle` node, turning it off. A collision event would then turn on the `Toggle` node, which would remain on and pass the update flow through to the `Translate` node each frame.
