How to add Double Jump to your Game

For this blog, we will have as a reference the previous one, in which we explained how to jump using the jumpHeight value

So far, the player can jump only if it isGrounded
To let it jump again, we need to create a new bool doubleJumpEnabled. It will become true after pressing the space key

Later, if it’s not grounded, the else statement will check if doubleJumpEnabled is true. if so, we press space key again to add the jumpHeight value again to yVelocity. This way the player will “jump” again

After that, doubleJumpEnabled will be set to false, for avoiding a new jump in the air
