i am fairly new to babylonjs and currently working on my first project, trying to bring the ngrx store and babylonjs together. As you can prolly imagine there are a lot of questions to be asked … but for now i will stick to this one :
Lets say i have 2 Boxes. The boxes are connected by a line, that can have numerous points. At the moment the boxes as well as the line are independant meshes. Now if i move one box, i want the corresponding line end to move with my box. What i am roughly thinking about is something like:
- Click on the box
- Have something like a MeshManager to find all Meshes that have to move with my box
- Move the box*
- update the points array of the line while dragging the box around
- when drag ends, dispatch an action to my store to update the domain model
- What would i ideally use to move my Box? The PositionGizmo or a mesh behavior? Are there more behaviors to come in future releases?
But: this feels rather complicated for something that i would consider a fairly common use case. I ve read about the TransformNode but that doesnt seem to help me with my problem since i dont want to move the complete line mesh.
A small and simple Playground using the gizmo to move the box around: https://www.babylonjs-playground.com/#4TMPFR#1
Best regards and thanks in advance!
