Add custom logic with the expression editor - EXPERIMENTAL

This feature is still experimental!

The expression editor allows you to build logic inside Pixotope control panel instead of Blueprint by using a drag and drop editor.

Add custom logic

Open the Expression Editor by clicking on the Sum icon
- The left side shows function options which can be dragged into the fields on the Output side marked as “Input”. For a list of available functions see below
- The expressions default state shows the Source function in the Input field. This means that the actions Source is send to the Target directly

If the Source function is not present in any of the fields inside the Expression Editor, the value of the actions Source will not be used.

Build your logic by dragging options from the list on the left to the expression editor on the right
To add "variables" to the expression, drag in the Input function
- an Input parameter is created on the action
  - the value of the input parameter is being sent to the target
Combine the different functions to build more complex logic

A button to increment by a custom step value

The logic is executed/The target is updated when

Updating an input does NOT execute the logic.

Function	Input options	Description
Source		Takes the source value
Input		Creates an input parameter and takes its value
Decimal	Value Digits	Allows to set the amount of digits for a number
Abs	Input	Returns the absolute value
Inc	Input	Returns the value + 1 To build an increment/decrement logic, feed the output back into the input.
Dec	Input	Returns the value -1
Add	Input Input	Adds input values
Sub	Input Input	Subtracts input values
Mul	Input Input	Multiplies input values
Div	Input Input	Divides input values
Min	Input Input	Returns the smaller number
Max	Input Input	Returns the larger number
Concat	Input Input	Combines the inputs into a single text Advanced example In the example above we combined two “concat“ nodes. However, it will always output plural for the word “apple“. As we want it to be singular when the number is 1, we need to use an If function.
If	Condition Then Else	Returns the Then value if the condition is true otherwise it returns the Else value Conditions: truthy: true, non-zero number false: false, 0
Key	Json Path
Engine		Select specific engines to be controlled Can not be combined with other functions! By default all actions are sent to the engines specified in the "Send to" engine list. To only send the action to specific machines Drag the engine function over This creates an Engine input parameter Double click the field next to the Engine input parameter Enter 1 or more machine names separated by a comma This is for example useful in an AR+XR setup.
