deregisterAfterRender?

[JackFalcon]

Hi. Too easy.

Anyone have a link to an example of how to deregister a beforeRender or afterRender callback?

looking for a good pattern... 

Or unregister...?

Thx.

Ok, maybe got it...

scene.unregisterAfterRender(unregister);

[JackFalcon]

Here it is (in a nice little pattern):

        scene.registerBeforeRender(function someCallback() {

            if(done){
                scene.unregisterBeforeRender(someCallback);
            }

        });

solved.

If you only need it to run once, it's built-in.  Your example will run for each render until 'done', so it's obviously different:

I mention this, because of the part you may find interesting; where it wraps the original function call into a variable for deregistration:

Or even better:

Quote

scene.onBeforeRenderObservable.addOnce(function() {

 

})

That is better.  I finally checked out the Observable, as that is not standard from the pattern - found the mask there too!  Never stop learning

What do you mean? 

[brianzinn]

@Deltakosh just meant that 'mask' is not in the GoF description.  I meant it in a good way that it looks useful

@Deltakosh and @brianzinn ... the best. Thanks for the insight and the code links! : )
