Hey, me again. i am trying to use the same button to play and pause a serial player. there are lots of similar posts, but almost all of them use a variable to toggle something high or low, and here i need to use different functions. i did most of the work, i think, based on some other examples. now only the pause works, it seems to me the bool is not switching states. I'm sure it is some simple logic mistake, but to be quite frank i am still incredibly bad at it (i am a puppet stop motion animator, it doesn't get more analogous than that...) . i would love if someone could point me to the probably obvious problem in the code.
Thank in advance!!!
