[Solved]How to limit the shooting direction of the sprite??

I use the following example to get start.

https://phaser.io/examples/v2/arcade-physics/shoot-the-pointer

When the arrow's angle  <= 90 and  >= 90, the arrow will stop move and can not shoot to the left!!!!

I use the follow code

function update() {
   //right
     if(sprite.angle <= -90 && sprite.angle >= -180){
    	sprite.angle=-90;
    } else if(sprite.angle >= 90 && sprite.angle <= 180){
    	sprite.angle=90;
    }
  //left
  /*
    if(sprite.angle >= -90 && sprite.angle <= 0){

      sprite.angle = -90;  

    } else if(sprite.angle <= 90 && sprite.angle >= 0){
      sprite.angle = 90;  
    } 

    */
}

 

But  I hope the bullet not shoot to the left, any idea??? Thanks you so much

You need to add the same angle constraints to bullet firing too.

So instead of firing when the pointer is down,

if (game.input.activePointer.isDown){
        fire();
}    

you fire when the pointer is down and your sprite follows your angle constraints.

if (game.input.activePointer.isDown && sprite.angle >= -90 && sprite.angle <=90){
    fire();
}
