Pause/Play Animation with slider

Grasshopper
1

I have a slider (range .001-1.00) that animates a simulation in GH. I am trying to incorporate a boolean that can stop and play the simulation. ‘Trigger’ is unsuccessful because I need to loop back to .001 to restart once it is complete.

something like this ?

not sure if there is a great way without scripting. My approach is to use ScheduleSolution - and I am also not sure if this is the best approach.

    // ...
    GrasshopperDocument.ScheduleSolution(interval, ScheduleSolutionCallback);
    // ...
    public void ScheduleSolutionCallback(GH_Document doc)
    {
       Component.ExpireSolution(false);
    }

Hi @Samantha_Garza1
script ---Rhino code pluginGH is new features in Rhino8 (grasshopper)
Maybee you open this in Rhino 7?
For fix error the code must bee make by old C# Component for Rhin7

Hi, can you supply full code? I can’t open this because I have rhino 7.

Thank you, I have tried to copy the code into a c# component for rhino 7, however I have been unsuccessful. Any suggestions?
