jerk issue in a side scroller game

[Vivek Agrawal]

Hello,

 

I am building a continuous sidescroller game using Phaser.

 

the game has parallex scrolling background, i have added the background as tilesprite and given it autoscroll.

i am spawning the ledges on which the player runs as the game progress.

 

my problem is that the game is a bit jerky in nature, it sometimes lags for a sec or two

 

what can i do to resolve this?

 

any suggestions are welcomed

Thanks
