Using Check Position Point Nodes

The Check Position Point nodes can be used to verify whether a specific MD Prop position point is occupied by any character in the scene, and direct the flow toward different branching events accordingly.

** Please note that this node is best suited for scenarios involving interactions between multiple characters, or between characters and objects (props or MD Props).

1. Create a project with at least two characters, a MD prop, and a T2 State Switch node.
   
   
2. Open the MP Node Graph panel. Right-click on the viewport space and choose Condition Node > Check Position Point.
   
   A new Check Position Point node will be inserted on view.
   
3. Drag a flow line from the Start node’s output and connect it to the Check Position Point node’s input.
   
4. Select the node and adjust the settings in the Attributes page.
   
   
   • MD Prop: Specify the target MD Prop for occupation status detection. If you use the dropper tool, click the waypoint marker (the flat disk with double arrows) instead of the model’s mesh.
     
   • Position: Choose Any or All for the True / False judgment based on multiple crowd occupation points.
     
     • Any: If any one of the points is occupied, the node outputs True.
     • All: Only when all points are occupied does the node output True.
5. Connect events to the outputs of the Check Position Point node.
   
   • True: Connect to a Character node, indicating that the character performs the Glance motion when the MD Prop is occupied.
   • False: Connect to a MD Prop – T2 State Switch node, which causes the character to sit when the MD Prop is not occupied.
6. Use joints to loop back from the True event for continuous detection.
   
7. Create another thread that drives the other character to walk to the MD Prop, occupy it, unoccupy it, and walk away.
   
8. Start the Go MD Mode to view the animation results.
