I have a game and I have the world moving towards you, and you can jump at the same time. both functions work separately, but they don't work when used together. sometimes it gives me an error(ValueError: could not convert string to float: expected) couldnt convert, sometimes the character does a weird jittery motion, sometimes it does both, and sometimes it just crashes. this is my code

i tried adding the afters like tadhg said, but it still only jumps sometimes, and most of the time it dosent do a full jump, or just goes up one or two pixels, then goes back down, then repeats for the amount of time it should be jumping.
