Separate Logic from Content

To program interaction logic, sequences or any other more complex tasks, you should NOT start to weave the logic part deep into your patches but rather have a central command station where you handle all the logical states in an abstract way and send them as needed to other places in your patch.

Note, if you see too many of these nodes in your patch and the logic gets more and more confusing it's time to switch to State Machine.

Conditions

Wondering how to control data flow in manner of if-else statements? See Conditions.

State Machine

Automata

Use Automata (Animation) for complex logical structures. Automata allows you to distill complex logic into a textual description. See it's extensive helppatch.

Qfsm graphical tool is good for drawing State Machines, it allows you to export state machine statements for the Automata (Animation).

Automata UI

There is also a much more convenient Automata UI contributed by u7angel which enables you to design your program logic with states and transitions as well as giving them a duration within a visual editor.

Sequence based logic

Use Timeliner (Animation) for more sequence based logic. It has an Automata track to jump in the timeline. How to use Timeliner.
