Using Position Nodes

The Position Node is used to detect the XY position of a specific object in the 3D scene, record it in the Log Output list on the Log page, or display the position value in the 3D scene using a particle-effect text emitter.

1. Create a project with a character, an MD prop and a particle-effect text emitter.
   
2. Open the MP Node Graph panel. Right-click on the viewport space and choose Print Node > Position.
   
   A new Position node will be inserted on view.
   
3. Drag a flow line from the Start node’s output and connect it to the Position node’s input.
   
4. Select the node and adjust the settings in the Attributes page.
   
   
   • Target: Select the object, in this case the character, to detect (based on the root). The XY position will be retrieved by this node.
   • Text Particle: If you want to use a particle emitter to display the XY value of the object, enable this checkbox, then select the emitter on stage using the drop-down list or the dropper tool.
5. By adding a joint, connect the output of the Position node to its input to continuously record the target object’s position during the Go MD session.
   
6. Create a new thread to drive the character to walk onto the MD Prop with new Start and Go To nodes.
   
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.
