create a new mesh per second?

[toaru]

Hello everyone, I'am just starting learning babylon js to build an environment for the demo of my AI project and I had a problem here.

What I want to do is very simple, I'd like to automatically create a "Ball" every second for example.

I tried to use OnEveryFrameTrigger on scene, but it does not work.

Here is a link of playground

Could any one help me. Thanks.

Welcome to the forum.  That Playground is actually a playground - thanks for sharing 

you can use setInterval.  I think what you had was generating a sphere, but you have to add an impostor and the actions again:

ps: everyFrame is ~60 spheres/second

There is a little bug with this, open the playground, change the tab for a few seconds and return to the tab ^^

It's not really a bug.  When the tab switches, the Scene doesn't render - that's a good thing if you have lots of tabs open!  That can definitely cause some undesired behaviour.  One solution is to run in the background, so start your create scene like this:

engine.renderEvenInBackground = true;

Other solution is to hook into window.addEventListener(...) for 'blur' and 'focus' and to pause your engine render loop.
