looping problem when player hits on enemy

[erich]

Hi

I have a script that I wish to implement so that if the player hits an enemy 3 times the game restarts, but it constally loops when touching, where am I going wrong ??

create function

this.currentHits = 3;
this.collisionHasOccurred = false;

update function :

this.game.physics.arcade.overlap(this.player, this.enemies, this.youLose, null, this);

youlose function :

youLose : function(player, enemies){
        
        if (!this.collisionHasOccurred)
        {
            this.currentHits --;
            this.collisionHasOccurred = true;
        } else {
            this.collisionHasOccurred = false;    
        }
            console.log(this.currentHits);
            console.log(this.collisionHasOccurred);

        if (this.currentHits === 0)
        {
            //this.game.state.start('Game');
            console.log('GAME OVER');
        }     
  },

thanks in advance

I did not understand the flag 'this.collisionHasOcurred'. When your youLose() method is called you should implement some time of delay because update is calling your method too fast and even though you put this flag the code is executed faster than you know. 

Try to deactivate the enemy for a while.

I would rename collissionHasOccurred to overlapping.

if (!this.game.physics.arcade.overlap(this.player, this.enemies, this.youLose, null, this)) overlapping = false;

And then do not reset overlapping inside the handler (remove the else block), otherwise it will loop.

@erich You have the right idea but for any overlap longer than 2 frames (very likely) `collisionHasOccurred` will be flipping back and forth and the player will still accrue hits.

You can use a timer:

// @create:

this.currentHits = 3;
this.setPlayerCanCollide();

// @update:

if (this.playerCanCollide) {
    this.game.physics.arcade.overlap(this.player, this.enemies, this.youLose, null, this);
}

// …

setPlayerCanCollide: function() {
    this.playerCanCollide = true;
}

youLose: function(player, enemies) {

    this.currentHits--;
    this.playerCanCollide = false;
    this.time.events.add(1000, this.setPlayerCanCollide, this);
    
    // …
}
