How to move all objects together with their layer

[Jaydabblju]

I am new to GM2 and tried to move a whole layer. But the instances of this layer stay on their position.

I tried:

// creating buttons
instance_create_layer(0,0,"menu",obj_btn_new_game);
instance_create_layer(0,100,"menu",obj_btn_load_game);

// moving the whole layer down
layer_y("menu",200);

But the objects don't move.

My target is to create a menu on a layer. After clicking on a button of that menu the whole layer shall move out of the screen.

Get the layer ID and use that to filter through all instances.

var menu_layer = layer_get_id("menu");
with (all) {
  if (layer == menu_layer) {
    y += 200;
  }
}

See: with block recipe cards

So moving the layer doesn't affect the postition of its instances? I have to go through all instances manually?

For what can I use "layer_y" and "layer"x" if the instances don't move?

The with loop FrostyCat posted will move all object instances, while technically being "manually going through all instances" it's just 6 lines of code to do it (because we tell it to loop over all objects instead of just specific objects or a specific ID).

Yes I get that.
But again: For what can I move the layer with "layer_x" and "layer_y" if the instances on this layer stay on their positions?

Background images, etc., for parallax effects, and things like that?

I highly agree. It would have made a very useful feature to move all instances inside the layer without having to loop through all of them, not that I am against using with, it just would have made the process more straightforward.

Loops pretty much is how you do batch operations...

I already know that, it just would have been more straightforward.
