It’s possible to add a group inside container ?
I tried this :
This.holder = this.scene.add.container(0,0)
grp = this.scene.add.group()
This.holder.add(grp)
But I have this error :
gameObject.once is not a function
child.willRender is not a function
No, you can not. Groups in Phaser 3 are simply a collection. The objects belonging to a group are always child objects of the scene.
What are you trying to do?
