Execution Flow blocks

Execution Flow blocks allow to switch sections of a program during its execution among a set of pre-configured options.

Execution flow blocks are divided into 2 different types of blocks: On focus block and Switch blocks.

On focus block

The On Focus block outputs a boolean value, which is only True the first time the block is executed.

• If used inside a Switch Block, the value will be True each time the case is selected.
• On Focus can be used to trigger actions or initialize variables whenever a case is switched.

The following example would initialize User Variable 01 to 7 whenever Landing phase is selected:

Switch blocks

• If-Else Switch block: Choose between two cases based on the state of a boolean variable.

  

  It is possible to swap the blocks of each case (False/True) by simply right-clicking inside an if/else switch block and selecting 'Invert'.

  

• Integer Switch block: Choose a case based on the value of an integer variable.

  

  Right click on the Integer switch block to access the configuration options:

  • Add Case: Create a new empty case.
  • Copy Case: Create a copy of the current case.
  • Delete Case: Delete the current case.

  • Add Entry: Add a new entry to the current case. An entry is a condition under which the case will be selected. The same entry can on only be in one case at a time. Adding an entry that already exists will move said entry to the current case.

  • Delete Entry: Remove an entry from the current case.

  • Set as Default case: The Default case will be executed whenever the switch condition does not match any of the existing entries.

• Phase Switch block: Same as Integer Switch, but using Flight Phases as the switch condition.

  

Use of switch blocks

• Add blocks inside: Drag and drop the desired block inside the Switch block:

  

• Input/Output: Right click inside a Switch block and select add Input/Output. To remove them, right click and select Remove Input/Output:
