Main thread gets frozen if emitter.update receives too big number

[antmelnyk]

If emitter.update receives very big number (like 10000000) as parameter, it will hang up the browser page. Particle limit had 500, spawn frequency 0.8.

Maybe is quite obvious that we should not pass big numbers into it as it expects the seconds elapsed since last update, but at least would be nice to have some fool-proof or warning. I've spend quite some time trying to figure out the bug (in my code accidentally passed big delta into the update call).

Hmm, the threshold for "too large" would be dependent on emitter settings (frequency + particle lifetime), and to detect said value and particularly to reduce the delta to an acceptable value would require a bit of math that I'd rather not do each frame given the rarity of someone improperly passing in too large an update value.

Fair enough. Of course the performance of emitting itself is more important than some edge case which is developer mistake anyway. I think we can close the issue 😊

Maybe would be nice to add some notice to the docs or method description, but is up to you of course, whether it's worth noticing with details regarding frequency and lifetime settings.
