How to disable updating when a sprite is out of camera view?

[jerry]

I believe phaser updates every sprite added to the game( I tried to set alive=false/autoCull=true/visible=false, none of them prevent updating.)

But it seems in many games, enemies only move and shoot when they r in the camera view or reach to a certain distance to the hero. I think this is more effective.

Any one know how to disable updating when a sprite is out of camera view, and enable it when it's in camera view. Thanks.

Maybe, Phaser.Sprite.exists in conjunction with Phaser.Sprite.checkWorldBounds and its corresponding onOutOfBounds and onEnterBounds events?

[YuShaN]

sprite.setAll('outOfBoundsKill', true);

sprite.setAll('checkWorldBounds', true);

 

Maybe like this?

I think you might want to try setting autoCull to false on that sprite.
