Advanced usage of the control panel

With the Store and the API Log tabs you can control every aspect of the Pixotope universe.

With great power comes great responsibility … and many ways to get unwanted results.

Make a backup of your show file before changing show file parameters through the control panel!

Control properties of current show

Using the Store tab you can control all properties of the current show file.

  1. Go to the Store tab

  2. Search for the parameter you would like to read/control

  3. Click and drag the red circle onto the canvas

The properties are alphabetically sorted and grouped based on the State of the Store service.

Replicate specific Pixotope functionality

The API Log tab lists all occurring API messages of the Pixotope network. You can

  • listen to and read values from them

  • (re-)trigger them

Start listening

  1. Go to the API Log tab

  2. If not already done, click the Play button in the bottom right corner to start logging messages

  3. Use the x button to clear the logs

    • Use the Keep options to set the maximum amount of messages to keep.

Find the action to replicate

  1. Trigger an action in Director which you would like to replicate or get data from

  2. Click the Pause button in the bottom right corner to stop listening to more messages

  3. Find the corresponding API message using the message type filters or the search field

In a Pixotope network there is continuous message traffic, which might make it harder to find the correct message. Filtering on the correct message type might help.

Double clicking a message in the API Log copies it to the clipboard. Depending on which one you double click, it copies either only the Topic, the Message or both.
