If you are not koding an effect and you are placing it in your world you are likely wanting that effect to play continuously.Some effects are one-off. You place it in your world as an fx gizmo, they fire and that’s it. Occasionally you may want that effect to continuously loop, such as a water splash. Try this in the gizmo’s brain (you may not be aware, but special effects have the ability to be koded too).
WHEN DO [toggle][has power]
WHEN [countdown timer][loop] DO [toggle][has power]
Experiment with timings (you could also use the [in frames] modifier) so you get the effect you want.
or you could play around with the pace of the effect so it last longer, plays slower or even freezes with the pace=0.
