Stopping a time* expression
Hi,
I have an image continuously scrolling across the screen at a constant rate, using the Offset effect.
I’ve applied this expression to the Offset’s x,y parameters:rate = -450;
value + [rate*time,0]I’ve also parented other layers to this expression to move with it. It works, but my problem is, I need it to come to a full stop occasionally, or just freeze. Is there a way to stop/start this expression using keyframes on a Checkbox or Slider control?
Thanks

I solved this one with the help of Dan Ebberts’ Motion script page–
Parenting the variable, (in this case, the “-450” in line one), to a slider with the Hold Frame expression from this page https://motionscript.com/articles/speed-control.html
made it work perfectly.Be sure make the sure the variables are consistent. I changed “rate” to “spd” in this case.
Props to Dan Ebberts
