Matter - gameObject.emit is not a function

[reinildo]

On Phaser 3 matterJs examples, like this one: http://labs.phaser.io/view.html?src=src\game%20objects\tilemap\collision\matter%20platformer%20with%20wall%20jumping.js
, when thow bodies collides we receive this error: i.gameObject.emit is not a function

Looking on the source code file: MatterCollisionEvents.js

if (bodyA.gameObject) {
  // bodyA.gameObject.emit('collide', bodyA, bodyB, pair)
      matter.Events.trigger('collide', bodyA, bodyB, pair)
 }

if I replace the commented line with code below it works without error.
Is it an issue or am I doing something wrong?

Thanks

It depends what the Game Object is. If it's a Sprite, Image, TileSprite, etc, then emit will work fine, as they have Event Emitters by default. If it's a Matter.Tile then it won't, as we never give individual tiles emitters.

In the phaser 3 example: http://labs.phaser.io/view.html?src=src\game%20objects\tilemap\collision\matter%20platformer%20with%20wall%20jumping.js
what should I do to fix the error?

[photonstorm]

Thank you for submitting this issue. We have fixed this and the fix has been pushed to the master branch. It will be part of the next release. If you get time to build and test it for yourself we would appreciate that.

What was the fix? What version is the last that did not have this bug?
I am on 3.15 and I got this error too.

[photonstorm]

It's impossible for 3.15 to have this error, as it came about as a result of a brand new plugin added in 3.22. The fix is for 3.23, which isn't published yet.

Awesome thanks for the info, any eta on 3.23 ?

Any update on when 3.23 will be released? I am experiencing this bug

As far as I know the update is supposed to be released sometime in April, there was a news blog posted about it, not sure if it was just for patrons or not.

You can use the master branch its quite stable and has a fix for it already.

Is there a timeline for when 3.23.0-beta1 will be published to NPM? At the moment I'm using a manually built version of Phaser which works but makes it harder to use typings (as it's not installed in node_modules).

[Brandoning]

I'm using 3.23-beta1 and I still seem to be getting this issue? Unless I modify the code to matter.Events.trigger it'll error

[embeddedt]

@Brandoning What type of game object is it? #4967 (comment)

[Brandoning]

@embeddedt it's a Phaser.Physics.Matter.Sprite

[embeddedt]

That's strange. I also use sprites in my game that collide with each other and I don't have this problem with 3.23-beta1.

This is the Phaser minified JS file I'm using (compiled from 7fbe57c last week).

Where can I get the 3.23-beta* versions? They are not on the npm and there is no git tag that includes 3.23.

Edit: I managed to do npm i https://github.com/photonstorm/phaser/tarball/master which installs the master branch directly. You can also use tags there but as I mentioned, there are no tags for 3.23 at the moment. (ref: https://stackoverflow.com/a/32436218/6301627)

[embeddedt]

Yes; you have to manually clone the master branch and build it. Nothing has been tagged yet.
