Hello there ! I’m making a multiplayer game and I want to change the player scene. When I change the scene, I can’t re-enable the physics on that scene !! My error occurs with this line of code. self.physics.world.enable(self.player); (self is the current scene) The error : Uncaught TypeError:…

Something like class Scene { create () { socket.on('currentPlayers', addCurrentPlayers, self); this.events.once('shutdown', function () { socket.off('currentPlayers', addCurrentPlayers, self); }); } }

[image] Santette: Uncaught TypeError: Cannot read property ‘enable’ of null What’s the stack trace (click :arrow_forward:︎)?

Likely the scene self is shutdown at that point. You probably need to remove that event listener when the scene stops.

I tried it but I’m not sure how to deal with it while it’s in a update loop. I tried several things like “if(self)” il the loop but still, doesent seems to be working. Here is the part where I call this function: update() { if (this.player) { if (this.player.x < 0) { socket.emit(‘preQuit’); t…

OK, I got it. I am using Scene.start instead of Scene.switch ! So the rigth way was : this.scene.switch('Scene2'); Thx for helping :slight_smile:

[image] Santette: this.scene.switch(‘Scene2’); It’s working but I’m running into another issue now. What I did was just start the ‘Scene2’ while the other one was running behind it. That’s something I neet to fix bc I want the create event to fire every time I join in. Another event could wor…

Go back to scene.start(), I think. If you’re adding event listeners in the scene create(), they need to be removed when the scene is stopped.

I’m not sure what type of listeners you are talking about. Socket listeners ? If so how sould I remove them ?

I think socket listeners, yes. Whatever is calling addOtherPlayers. How/where are you adding them?

So I initialise the socket one on login, then no more. I call the addOtherPlayers function whenever I join a scene. My issue is that when changing scenes, the listener on Scene1 doesent stop, even if the scene is “deleted” with “self.scene.start(Scene2)”.
