solved registerBeforeRender on childmeshes created in "for loop"

[Myjestic]

Hi all,

how can I apply some registerBeforeRender actions to a childmesh within a for loop?

Please look at this PG - Row 91 and 92.

Finally, all cubes should spin.

I tried with arrays and objects for "Sphere" but this did not work.

Hi @Myjestic

Just push a reference of each clone into an array and loop the array

... sometimes ... I can't see the wood of the trees. 

Thank you, this is a good approach.

 

But why is it not possible to do the registerBeforeRender in the same loop?

@Myjestic 
It is also possible with a little change, adding the registerBeforeRender to the child itself,

I just prefer it the other way  

Have a nice friday.

Just for understanding - 

What you did it working. But only for the last sphere defined  The async function you register (in the registerBeforeRender) is using the sphere variable reference. As sphere is defined in the scope above it, and javascript hoists variables, the sphere reference inside this function always directs to the last sphere you created. @aWeirdo (Hey, I always find it hard calling you that ) suggested a great way of solving this.  Personally, I like using the forEach function over arrays, as it creates a new context each time you run it. If you want to register a function for each sphere, this is how I would to this:

I find it cleaner, but it is all a matter of taste in that case.

You guys are great! Thank you.
