How to disable default pointer move?

[adam]

I've been working on something that required me to look into the scene._internalPick.

https://github.com/BabylonJS/Babylon.js/blob/99bb973bee5779f5941a28767b801035b58782a0/src/babylon.scene.js#L1964

Every time the mouse moves it loops through the meshes in the scene and if the mesh passes the predicate test it checks to see if the ray intersects it.   The intersect method allocates a BABYLON.PickingInfo object on each call.  If a PickingInfo object isn't created on the last pass of the loop, one is allocated to return to the caller of internalPick.

I'm pretty sure this happens by default:

What would be a good way to disable that if someone doesn't need it?

I'm aware I can do this:

scene.pointerMovePredicate = function (mesh) {
      return false;
}

but the _internalPick function is still called and loops through all the meshes.

Typescript doesn't like this:

var eventPrefix = BABYLON.Tools.GetPointerPrefix();
scene.getEngine().getRenderingCanvas().removeEventListener(eventPrefix + "move", scene.onPointerMove);

About TypeScript - cast the rendering canvas to HTMLElement, should do the trick.

It's complaining about scene.onPointerMove.  I'm supposed to be referencing scene._onPointerMove, but it is private.

What about calling scene.detachControl(canvas) ?

[adam]

That would remove pointerDown, which I would like to use.

Ok..Understodd.Give me a few minutes

clock's ticking....

Ok...so new version

call scene.detachControl() and now you can call scene.attachControl(true, true, false)

here is the new attachControl signature:public attachControl(attachUp = true, attachDown = true, attachMove = true) {

Thanks!
