    also is there a windows bug that stops particles alpha from going down?

    If your particles have no image applied you will be unable to use the alpha channel.

    Too little information to offer any input, all we know here is that you press the space bar and the particle's life is set to 2 seconds, that's pretty slim pickings even for the most enthusitic problem solvers. Maybe upload a screenshot of the rules for the actors involved.

    False! I can change the alpha channel of a particle without needing an image.

    It could be when button pressed. The particles will only happen when pressed. So as soon as you lift your finger it stops? You need a timer for behavior to finish or change Boolean.

    But I'm just guessing.

    I was specifically answering Skipnice's question ["also is there a windows bug that stops particles alpha from going down?"] - so to clarify, you cannot animate a particle's alpha channel down (from alpha = 1) if there is no image applied to the particles.

    You can change the alpha channel overall, you can even animate the alpha channel up (from transparent to solid), you just need to apply an image if you want to animate it down.

    I must not be understanding you because I can go up from 0 (like you said) and down from 1 while no image is applied. I'm sorry that that previous post of mine sounded rude

    To be honest I've not checked (and have no access to GS right now), but in all the recent previous versions it worked (or didn't work!) like this:

    [1 animating to 1] = 1
    [0 animating to 1] = 0 transitioning to 1.
    [1 animating to 0] = 1

    And the way to get around [1 animating to 0] not working was to apply an image the particles, then it worked as expected.

    I didn't think your post was rude at all.

    Hmmm. @Socks that is interesting. It might be a bug with his Creator still. @skipnice could you show us your particle rules?
