P2 物理体在 setRectangle() 调用 phaserJS 后没有发生碰撞

Question

我正在创建鱼精灵。与 foodCollisionGroup 发生碰撞。鱼吃一些食物。玩游戏效果很好。之后我调整它的大小（增加鱼的大小）并且它停止与食物碰撞。我认为它可能不会因为调用了 setRectangle 而与食物发生碰撞。我有另一个问题，即 fishFoodCount 增加了两次。如何解决这两个问题

Fish.prototype.create = function(x, y){
    this.fish = game.add.sprite(x, y, this.spriteName);
    this.fish.physicsBodyType = Phaser.Physics.P2JS;
    game.physics.p2.enable(this.fish);
    this.fish.enableBody = true;
    this.fish.anchor.setTo(0.5,0.5);
    this.fish.body.collideWorldBounds = true;
    this.fish.animations.add('idle', [3 + (this.index * 8)], 10, false);
    this.fish.animations.add('move', this.getAnimationFramesArrayFor(this.index) , this.AnimationFrameRate, true);  
    this.fish.play('idle');
    this.fish.body.fixedRotation = true;
}

-------

Fish.prototype.setFishSize = function(width, height){
    this.fish.width = width;
    this.fish.height = height;
    this.fish.body.setRectangle(height/2, width/1.8, width/3.3, 0);
}

-------

Fish.prototype.eatFood = function(fish, food) {

    if(this.fishFoodCount > 9){
        this.setFishSize(game.width/25, game.height/4);
    }
    this.fishFoodCount += 1;
        food.sprite.kill();

}

使用setRectangle()后需要重新申请碰撞组。

P2 物理体在 setRectangle() 调用 phaserJS 后没有发生碰撞

P2 physics body not colliding after setRectangle() called phaserJS

javascript

game-physics

phaser-framework
