Hi all, I’m trying to abstract out sprite creation to a custom class but I’m getting an error when adding it to a collision category. Of critical note here is that I’m using Matter, not Arcade. Here’s my class: class Enemy extends Phaser.GameObjects.Sprite { constructor(config){ super(config.…

hi, there is the solution class Sprite_Matter extends Phaser.Physics.Matter.Sprite { constructor(scene,x,y,texture) { super(scene.matter.world,x,y,texture); this.setTexture(texture) this.setFrictionAir(0.0005) this.setBounce(.1) scene.add.existing(this) } preUpdate(time, delta) { sup…

Your post uses Arcade physics, not Matter. There is no equivalent this.scene.matter.world.enableBody(). this.scene.matter.world.add(this) didn’t throw an error, but it also didn’t result in setCollisionGroup() being injected, nor the pink box being drawn.

The first argument should be scene.matter.world, not scene.

So super(config.scene,config.x,config.y,config.atlas,config.frame); should be super(config.scene.matter.world,config.x,config.y,config.atlas,config.frame); ? Looking at the docs - yeah, that would seem to be the case. However, that throws an exception: Cannot read property 'queueDepthSort' of …

That did it! The problem was I was extending Phaser.GameObjects.Sprite, not Phaser.Physics.Matter.Sprite. Is this documented somewhere other than the actual code? It’s really confusing how in some places “physics” refers to Arcade, and others it’s just a generic namespace.

class Sprite_normal extends Phaser.GameObjects.Sprite { constructor (scene, x, y) { super(scene, x, y); this.setTexture('brain'); this.setPosition(x, y); scene.add.existing(this) } preUpdate (time, delta) { } }

try this, if you want arcade class Mario extends Phaser.GameObjects.Sprite { constructor(scene,x,y,key) { super(scene, x, y, key); scene.physics.world.enable(this); scene.add.existing(this); this.body.maxVelocity.x = 200; this.body.maxVelocity.y = 500; …
