In game menu

There is a node that manage the display of menus like shipyard or the fleet composition. The node is in hud/menu_layer.gd and a node called MenuLayer can be found in hud/hud.tscn.

Menu Layer

For the moment the menus are instanced by this node (and free them when the MenuLayer exists the tree). MenuLayer is used by dependency injection as a service that client (node that request menus on events) have a reference to. It is advice be craful when the menuLayer is instanced ! In hud.tscn the variable is injected on ready, but the ready event propagate from the leafs toward the root meaning that the leafs call _ready() before the hud. It is advice to use a setget if the Reference to MenuLayer needs to climb through multiple scenes towards the leafs.

Creating a menu

It is advice to create a menu using MenuContainer or a class extending it.
