Add enums

[darkhog]

They could be declared like

enum enemytype
    goomba
    koopa
    hammerbro

then an enum variable could be declared like that:

enemytype enemy_type

and would basically be equivalent of

ct U ENEMY_GOOMBA     = 0
ct U ENEMY_KOOPA      = 1
ct U ENEMY_HAMMER_BRO = 2
U enemy_type

Basically, it would make the code prettier and with less possibility of accidental bugs (you'd have to consciously add another enemy type to the enum instead of hamming up and putting it spawn_enemy(4) when you meant enemy 3. Because enums would be basically numbers under the hood, they would be usable in a switch statements, like this:

enum scene
    main_menu
    main_game
vars
    scene current_scene = main_menu
switch current_scene
    case main_menu
        process_mainmenu()
        break
    case main_game
        process_maingame()
        break
    default:
        break

This would be great for state machines and would avoid the headache of having to define countless constants (also would spare the developer wondering why stuff breaks or doesn't work when wrong value was provided by accident).

It's a good idea. I've thought about adding enums before, but it might be some time.
