I am very new to Phaser, only started out a few days ago. As you might expect, I will do some dumb mistakes. My issue here is that my character that works, (the one controllable with arrow keys) has the ability to jump to infinity. I have tried a bit of code with a double if condition to solve this, but I can't get the syntax right and I don't know how to check if the player is touching the horizontal wall or not. (I don't want it to jump unless it's touching the horizontal wall, that way I can't keep on jumping in mid air. Here's the horrible bit of code I am attempting to get to work: //if i'm pressing up AND the player is touching the wall THEN set vertical velocity to -500px. else if (this.cursor.up.isDown) && (this.player.body.touching.wallH == true) { this.player.body.velocity.y = -500; } I have attached all my actual code. I'm new here, I don't know how to write this condition, thanks for your help main.js
