Set X of Physics Group

[hby2000]

I am confused because Groups don't work in Phaser as I would expect them to. How do I move all objects at once while keeping their relative distance to another? All transform methods seem to work on a for-each-basis but I want to transform the group as I would transform a single object.
 

platforms = game.add.physicsGroup();
platforms.create(100, 150, 'platform');
platforms.create(300, 300, 'platform');
platforms.create(500, 450, 'platform');

//I want to keep the group's layout, so this doesn't work
platforms.setX(-100);

//this does nothing
platforms.x = -100

Hello, I guess you can use:

platforms.incX(-100);:

Thanks! Somehow missed it reading the docs.

Whoops, no this doesn't really help. I want to move the group to the last pointer X position, so I'm dealing in absolute values, not relatives. I tried

incX(pointer.x - pointer.prevPosition.x)

and it does somehow what I want. But it also gives unexpected results. I would've tried to wrap everything in a container but it doesn't take groups as children. Is this really such an exotic use case? Moving a group as a whole?

I found this thread and it really seems it's not possible in Phaser 3. Have to find a workaround then.

Glad you found that thread! I haven't used them myself but I figure Containers would be what you're looking for. I remember reading about them from this devlog: https://phaser.io/phaser3/devlog/120
