How do I check how many times a sinewave behaviour has completed a cycle?

I'm trying to check how many times the sinewave behaviour has completed a cycle but with little success.

I've tried comparing the cycle position. Something like "if it's greater than 0.9 add 1 to Cycle counter (trigger once)" but that is no good, because if the period is small enough, it will just miss the condition because it will just go past 0.9 directly to 0.

Is there a foolproof way to count the cycles of a sinewave that doesn't miss?

You can compare every tick the cycle position, if the current value is less than the value of the last tick, it means a cycle was completed.

Thanks for the response!

I forgot to mention on the original post, I need to check it before it starts again. I want to disable it before a new cycle begins. So like, if I want it to repeat only once, it will stop before the second cycle.

If it starts again, even if at 0 it will still have an undesirable effect.

Any ideas?
