  • Hey i've been trying to build a color changing particle system but something is wrong and i can't fix it <img src="smileys/smiley18.gif" border="0" align="middle">

    I've been trying to make some flames but the particle system breaks after a second or sooner and doesn't fade correctly anymore.

    It also seems VERY slow and doesn't spawn enough particle for my taste :(

    Here's my test .capx:

  • Get rid of all "For each" conditions, they are totaly useless there.

    Gather the two "Every tick" events into a single one.

    This should give a first start.

    You might also want to change the opacity factor in event 2 (now blank, turn it into a Particle.Opacity > 3) from 3 to 1. (Set opacity Particle.Opacity-1)

    Also, I don't know what you tempted to achieve with the yellow particle, but there's a flaw in the logic somewhere as it is now.

    Anyway hope it helps already, I get naturaly up to 192 particles with this setup, and all is fluid.

    Fixed capx

  • Well you've cleaned it up a bit but totally broke what i wanted to achieve.

    What i've TRIED todo was:

    1. Red Particle fades to 50% Opacity

    2. Red Particle spawns new invisible yellow Particle

    3. Yellow Particle is in same place as red particle

    4. Yellow Opacity is increased to near 100%

    5. Killswitch for yellow Particle is set to fade it out and then destroy it

  • That's not what was programmed at first in your first capx.

    Anyway Fixed 2.

    I added the bullet behavior to particle2 too.

    At first I tried to set the positions of particle2 to particle but the problem is the lifespawn of particle is far shorter than the one of particle2, and so the particle2 seemed to "freeze" at some point on the screen, and didn't go further (since there wasn't the instance of particle to pick).

    Anyway, tweaking with the values in the capx should help you to get the desired effect.

    To me, atm, it looks like some flame/fire.

  • Yay that helped! :D

    I've tweeked it a bit and now it's looking kinda how i wanted... a nice comic-style flame / torch effect:

  • If I were you, I'd even change Particle2 size.

    Try to put it 6X6 <img src="smileys/smiley2.gif" border="0" align="middle" />

  • Nice!! I was actually going to have to make the same effect but using smoke!! So now i don't have to figure out much just change the color :)

    So thanks :)
