onOutOfBounds

[Matt]

Hi everyone,

 

I'm new to phaser and to this forum

google couldn't find me an answer so i had to make an account to post.

 

I am having an issue with onOutOfBounds being triggered when a sprite is entering.

This happens at random and tends to happen several times to the one sprite in a row

 

just wondering what could cause this and how exactly does onOutOfBounds work?

Hi Matt, onOutOfBounds is dispatched when a sprite leaves the world, that´s all.

Also, you can kill that sprite if its property outOfBoundsKill is true.

 

Hope it helps.

Hey, thanks for the reply,

I did already understand that much about the event,

still not sure why the event is being triggered several times in one frame.

 

here is the code that i'm using;
I may have altered it a little by now but any feedback will help

 

//spawns enemies on a timer

enemiesCtrl: function(){

//need to edit this to do something different down the track

   if(this.enemyTimer >= 50 && this.enemyCounter <= 15){

       this.enemyTimer = 0;

       this.enemySpawner();

       this.enemyCounter ++;

   }else{

       this.enemyTimer ++;

   }

},

//creates new enemy within enemies group

enemySpawner: function(){

        var enemy = this.enemies.create(-30, -30, 'red');

        enemy.scale.setTo(0.5, 0.5);

        enemy.checkWorldBounds = true;

enemy.events.onOutOfBounds.add(this.enemyOob, this);

        this.enemyReset(enemy);

    },

//repositions the enemy and resets direction

enemyReset: function(enemy){

var side = Math.floor((Math.random()*2)+1);

  if(side==1){

        enemy.x = -30;

        enemy.y = Math.floor((Math.random() * 800) + 1);

 

        enemy.body.velocity.x = 100;

  }else{

        enemy.x = 800;

        enemy.y = Math.floor((Math.random() * 800) + 1);

 

        enemy.body.velocity.x = -100;

  }

},

//triggers reset function when enemy leaves the screen

enemyOob: function(enemy){

if((enemy.y >750 && enemy.body.velocity > 0)||(enemy.y <50 && enemy.body.velocity < 0)){

this.enemyReset(enemy);;

}

}

Well, I guess more than one enemy are leaving the world in that frame/step...

[Matt]

oh okay, i can work with that
