shifting particles

New to it and having great problems animating a particle layer across the stage.

I have a section of moving grass as part of a larger group containing 20 or so layers. All other layers in the group move fine but the particle does not.
I've tried putting it in a group of its own, inside the larger group, but still the grass waves just about stationary while the other layers perform.

Any ideas. Is this a characteristic of particles.

You should post the sample file or the layer structure screen and the particles parameters you used. If not is so difficult to tell you what's wrong.

Just a guess: the other layers move (relative to camera), and the particles don't? Select the particle layer and use some layer translation.

You can see the layer windows here.

The problem is with moving the particles using the layer translation tool.

According to the particles parameters you have shown, the particles have a lifetime of 0 frames. This means that that each particle would live for ever once it appears. Also your particles have velocity = 0 so they must be "on at start" (if not they are never shown because cannot be launched (velocity =0)).
The problem comes with the "free floating" thing. If you check it "on" and also all the particles are shown since the beginning of the animation ("on at start") they are just "free floating" all the time that you move the layers (the particles or the group layer) so they wouldn't move at all.
Just check off the "Free floating" and it should solve your problem.

Fantastic

Thanks for that.
