Recommended Posts

Hello, guys.

I'm newbie on 3d programming.

I want to display sprite like GUI that has a function linkWithMesh. but it hasn't.

In this example,  sprite's position from a mesh is changing, not fixed.


the mesh must have BILLBOARDMODE_ALL.

how to make sprite to track mesh's position like GUI's linkWithMesh.

Welcome to the forum.

Even thou sprite looks 2d, we are 3d in our core. You will need to update the position in all axes in order to place the sprite on top of the mesh. Here is an example how it can be done: https://www.babylonjs-playground.com/#87HQN6#1

If dealing with different types of nodes, ou could also use the parenting system (http://doc.babylonjs.com/tutorials/position,_rotation,_scaling , search for parenting).
