¿how to optimize my code for double jump?

[jopcode]

Hi guys, i have a code for the double jump, but sometimes this don't work correctly and my player can't jump, I'm noob with phaser, and someone can help me to optimize my code please

This is my code(jumpCound and jumpMax has been declared in create function):

  this.upKey = this.game.input.keyboard.addKey(Phaser.Keyboard.UP);
        if(this.upKey.downDuration(20)) {
          if(this.jumpCount < this.jumpMax) {
            this.jumpCount++;
            this.player.body.velocity.y = -500;
            console.log(this.jumpMax + ' ' + this.jumpCount);
          }
        }
        if(this.player.body.blocked.down || this.player.body.touching.down) {
          this.jumpCount = 0;
        }

This code has been declared in UPDATE function

@Tom Atom With this code happen to something similar that with my code, sometimes I'm can't to double jump, only can jump one time, any idea?

[Tom Atom]

@jopcode - that code was taken from games in production. Only thing is here:

this._nextJumpTime = this.game.time.time + 250;

 It prevents you to start next jump 250 millis after previous one. You may decrease it and see if it helps.

 What browser do you use for testing?

@Tom Atom With Chrome, trying now decrease that

@Tom Atom I solved it, using my code with only one variation in:

if(this.upKey.downDuration(20)) 

changed it for :

if(this.upKey.justDown) 

And the double jump work correctly, very thanks for you help <3
