Working on a 2D platformer, and you know how in some games, the jump depends on how long the button is held? Well, I’d like to do that, with two different heights for jumping, a normal jump when the button is tapped versus a high jump when it’s held for a certain amount of time. I’d also like it to begin the jump as soon as the button is pressed, and figure out mid-air whether it’s a high-jump or not.
Unfortunately, I haven’t had any luck even correlating what I’m doing with what’s happening on the screen. Hoping someone can help.
