rapid spawning of objects, changing opacity with timedelta

Hello. Hopefully someone can assist with my query.

I have some bullet objects flying about, and every tick they spawn a non moving "trail" sprite, which scales down, and fades down in opacity every tick. creating some nice "tails" on each bullet.

However, I'm just fixing all my code to work with time delta, and I am unsure how to do spawning as well as scaling / opacity changes at the same rate using time delta.

Thanks as always!

The scaling and opacity change can be set by multiplying the decrement by dt, as usual.

For instance:

sprite.Opacity = sprite.Opacity - opacityDecrement * dt
sprite.Scale = sprite.Scale - sacleDecrement * dt

The spawning will be already fine if you're using a time tag for spawning, like "Every X seconds".

Hope this helps. Cheers!

Thanks Bruno, as always!
