true and false case switch periodically

[jetfire]

I try to use a case structure with the following function.  For example:in the true case, it runs 20s and then switch to false case and run 30s automaticlly and run true case for 20s,then to false case for  30s,like this  periodically switch.with another threads found i a simple example in my posted code：every 30s  switch case between true and false,but i don‘t konw how to modify it for periodically swtiching,f anyone can give me some ideas about case switch periodically that would be appreciated.

Have the cases output how long the Elapsed Time should count for.

thank you.is your means  two case structurs inside Loop.one of them has output how long the Elapsed Time？

You only have 1 case structure.  In the case structure, have each case output a time to elapse.  Thinking about this further, you should store that time in a shift register since you want the elasped time on the next iteration to get that value.
