Tips and Tricks for more complex Actions

Less Code

Conditional Statements can be used to create blocks of logic depending on variable input. But you don't need to put the entire configuration inside each if statement. You can save a lot of time by first setting the general properties, and only setting specific ones inside each if statement.
For example: Rather than doing:

You can save some time and trouble (which will increase exponentially as the script gets more complex) by using:

Centralized Code

In cases where multiple variables need to trigger the same (or similar) logic, it can get very burdensome to manage that logic in the "On Change" action of all individual variables.
