Using Boolean Nodes

The Boolean Node can be used to retrieve the value of a Boolean parameter and record it in the Log Output list on the Log page, or display the value in the 3D scene using a particle-effect text emitter.

1. Create a project with a character and a particle-effect text emitter.
   
2. In the Variable page, add a new Boolean variable.
   
3. Open the MP Node Graph panel. Right-click on the viewport space and choose Print Node > Boolean.
   
   A new Boolean node will be inserted on view.
   
4. Drag a flow line from the Start node’s output and connect it to the Boolean node’s input.
   
5. Select the node and adjust the settings in the Attributes page.
   
   
   • Boolean: You can select the Boolean set created in Step 2. The Boolean value will be retrieved by this node.
   • Text Particle: If you want to use a particle emitter to display the Boolean name and value on stage, enable this checkbox. Then select the emitter on stage using the drop-down list or the dropper tool.
6. Optionally activate the Loop setting of the Start node.
   
7. Start the Go MD Mode to view the animation results.
   
8. You can switch to the Log page to view the Log Output obtained by the Node. The emitter also displays the string from this list.
   
   1. Save Log: Save the log as a file (*.txt).
   2. Clear Log: Clear the data in the Log Output list.
