How to swap jumping method in StateModes?

[still tide]

This is my PlayerController code. I've installed a coyotetimer and such in order to make it possible to jump twice in a row, but make sure you can't just keep spacebar pressed to jump. Now I've also got a swimming function.. but for that I do need to keep spacebar pressed to consistently go up. I want to fix this, but I am not entirely sure how and would like to receive some input. https://pastebin.com/wzukVgnD
