Footprints

edited January 2013 in Working with GS (Mac)
I am working on something where my character is viewed from overhead. I want to have a steady trail of footprints which stay for about 10 seconds but I cannot seem to get it to function in a steady stream of about 4 images per second.
I'm sure it is in the Spawn Rate.. but I am not sure what the 3 settings should be.. I keep getting a few in a group.. then sperratic groups afterwards...
Can someone tell me about what my Spawn and Startup time should be...
Velocity and Position - all 0's
Size - 20 does not change
Color - White, changes to 0 Alpha over 10 seconds, Blending Normal
Rotation - Rotation is game.PlayerR (constrained to my character's rotation)
Image - a little pair of footprints

thanks

    Particle effects tend to be like that, a bit random, I'd use Spawn Actor instead.

    Put a timer in the footprints actor to fade it out and remove it from scene after a set period of time. Something like:

    Timer:

    After 5 seconds

    Interpolate Alpha to 0, duration 1 second (or whatever)


    Timer:

    After 1 second (this should match your Interpolation duration) Destroy this actor

    Fading an actor is a very simple process, simply interpolate it's alpha to 0.
    . . and 2, didnt want a billion actors.. I'm workin it...
    Destroying an actor is, again, a very simple process, use the 'Destroy Actor' behaviour when you've finished with the actor.

    Thanks to Both of ya.. I was doing the Timer thing for destruction but I never messed with the Interpolate before, so now that's awesome to know!!! My biggest fear was all the timers.. just had the image of the device processor with about 100 stop watches.. 8-}

    I've heard bad things about timers here on the forum but I haven't experienced any problems with them yet. So until I do I'm not going to worry about it.

    I assume if you have a really really large amount of them it will be an issue, I have not reached that limit yet. :)

    I was going to suggest Pawn Stars or Hardcore Pawn for video tutorials.

    Instead of using a second Timer to destroy, you could try setting a When the actor's alpha is 0, Destroy Actor.

    Also, although this would be a different visual effect, you could start the Interpolate right away and have it last longer. The footsteps would be fading from the get go, but you'd do away with both Timers.

    I like the if Alpha=0 destroy.. gonna try that, if anything, it will drop a function.. Thanx

    Nice trick !

    'Ease Out' would help a little here.
