Particles disappear when adjusting ParticleEmitter.Timescale

[MemzDev]

When changing ParticleEmitter.Timescale, existing particles can only have their speed adjusted once, before immediately dissapearing the next time Timescale is changed

Consistent 100% of the time

The video above has code to set Timescale to 0.1 when E is held down, and goes back to 1 when released.

The issue started appearing about a month ago

hi thanks for responding

i personally really like having slow motion / hitstop effects in my game
currently, i cant use these without compromising on my visual effects, as the more i slow things down, the faster they disappear

this issue becomes even more noticeable when players use the frame-stepping features in my training mode

[neutrinostack]

Got it! Thanks for the details.

We know why this is happening and have a few ideas how we can fix it without breaking/reverting the previous fixes. We’ll work on that in the next few weeks. I’ll post here an update once it’s ready.

Thanks again for bringing it to our attention. We were discussing the possibility of such effect a month ago, but were not sure if anyone actually uses the Timescale this way.

Hey, wanted to drop in and say this is affecting our game’s effects as well

Take a look at the wind shockwaves below my character right after the jump; they’re supposed to go back to normal speed, but they just disappear. Would love to see a fix soon!

[neutrinostack]

The fix is almost ready. We’re testing it internally. Thank you for your patience. I’ll post an update here when it’s available to the public.

[MemzDev]

Awesome! Thanks for keeping us updated

[neutrinostack]
