Expressions properties

Expression editor is used to perform arithmetic on values outputted from ScreenPositionAxis objects to a property of a defined screen

Expression 

These are the arithmetic expressions performed on the defined axes. The ScreenPositionAxis objects are defined by their name. For example,

(ledscreenx*ledscreeny)/2

Where ledscreenx and ledscreeny are ScreenPositionAxis objects.

Screen

The screen you want to move and rotate. You should leave the property field of the object blank if you want to use the output of the expression rather than the axis.

Min input

The minimum input value that will be received from the ScreenPositionAxis objects.

Max input

The maximum input value that will be received from the ScreenPositionAxis objects.

Min output

The minimum output value of the defined property.

Max output

The maximum output value of the defined property.

Output

The current output value.
