Jumping

[thorny root]

i tried to do jumping but i don't know how to make it so the player cannot jump more than once

you should use a boolean instead i think? i am not sure

You're missing the "if" in between so that it can tell if you are pressing space or not.
The bool that comes out of getkey says wether or not you are currently pressing the space key
Also, you dont need to plug in the get key to the flow, you can just pull the bool from it like in the image, but i dont think it has any effect besides looking different/better

thanks. but i gave up and decided to use other engines

fair enough xd

It's because you have an only one node lol

I think at least

The if statement might still be used but check for the once node

But it is the code for jumping. I wanted to make it so i can jump once and when i touch floor it resets

you mean cannot jump while in the air?

You normally raycast or circlecast for ground to find out if you're on the ground, only then you are allowed to jump
