If/Else: This will execute code depending on wether a certain condition is met. Like this:

This code will move the camera forward .5 meters if the variable "number" is greater than two, and backwards if the variable is not greater than two. If the code was executed, the camera would move back.

Do while: This will repeat code until the given condition is not true.
Example:

This will increase the value of the variable "number" and then wait for one second, repeating until number is not less than five, then turn the camera.

Do together: This will execute multiple lines of code at the same time.
Example:

This will spin the camera and move it up at the same time.

Do in order: This will execute lines of code one at a time. This is primarily used inside Do Togethers.
Example:

This will spin the camera twice, over a two-second period. While the camera is spinning, the ground will change to red, then to blue.
