I took the bullet examples from http://phaser.io/examples/v3/view/physics/arcade/bullets-group and modify for horizontal firing
When I fire, sometimes the bullet got stuck as per the attach image below:-
The game is located at https://stanleyseow.github.io/js/phaser/scene-shooter/
I have also enable window.bullets, window.player and window.stars so you can access it directly from the console.
Can someone suggest why this is happening and help me take a look at the codes , I also pasted it to pastebin
