Can not get Double Jump to work

[jdiperla]

I am trying to get the player character to do a dumble jump when the character presses space while the character is already jumping. But it just keeps going:

`keyPress("space", () => {
// these 2 functions are provided by body() component

let jump = 0;
console.log(jump);
console.log("space pressed");
if (player.grounded()) {
	jump = 0;
	player.jump(JUMP_FORCE);
}

if (jump < 2 && !player.grounded()) {
	player.jump(JUMP_FORCE);
	jump = 1 ;
	
}
if (jump == 1 && !player.grounded()) {
	player.grounded();
	jump = 0;
		}

});`

there's double jump in the "sticky" example where it's packed into a component (maybe i should just renamed it to "doublejump"):

// custom component to handle double jump
function djump() {
	let hasDouble = true;
	return {
		id: "djump",
		// requires the "body" component
		require: [ "body", ],
		// runs once on add
		add() {
			this.on("grounded", () => {
				hasDouble = true;
			});
		},
		djump(...args) {
			if (this.grounded()) {
				this.jump(...args);
			} else if (hasDouble) {
				hasDouble = false;
				this.jump(...args);
				// triggers a custom event
				this.trigger("djump");
			}
		},
	};
}

// add player character
const player = add([
	sprite("car"),
	area(),
	body(),
	pos(),
	// use our custom component here
	djump(),
]);

// use the patched djump() instead of normal jump()
keyPress("space", () => {
	player.djump();
});
