BYTEPATH #3 - Rooms and Areas about blog HOT 10 OPEN

There won't be multiple areas in one room. I separate both concepts because I prefer having one thing that deals with object management and another thing that is used for everything else. You could have a Room inherit from Area, or have Area be a mixin that gets injected into Room objects, or you could just have the same object management code for all rooms that you create without an Area object and the same effect would be achieved.

Instead of using:

function gotoRoom(room_type, ...)
    current_room = _G[room_type](...)
end

and calling if input:pressed('1') then goToRoom('RoomCircle')
why couldn't (or shouldn't) we use:

function goToRoom(roomIndex)
     currentRoom = roomIndex
end

which removes the need to pass in the room name as a string and allows us to pass in the name as the variable itself such as if input:pressed('1') then goToRoom(RoomCircle)?

The Moses library from the previous part also includes a UUID function uniqueId() (also aliased to uid()), which can optionally take in a template string.

It seems to generate numbers sequentially from 0 (0, 1, 2, 3, ...); I haven't completed the tutorial but can't see why there would be a problem with that.

Hi, SSYGEN, can i ask you a question? Why do you abstract the concept "Area"? I think the "Room" can handle gameObjects management, will there be multiple areas in one room?

from blog.

maybe i miss something but when using a = Area:new(room_name) it gives me an error saying that a is nil, but when using a = Area(room_name) it lets me use the update and draw functions. what is wrong? i tried to print everything to see what is wrong but i can't figure it out.

First, thanks for your sharing! :)

gotoRoom() function will be better like this?

function gotoRoom(room_type, room_name, ...)
    if current_room and current_room.deactivate then 
        current_room:deactivate()
    end

    if rooms[room_name] then
        current_room = rooms[room_name]
    else
        current_room = addRoom(room_type, room_name, ...)
    end

    if current_room.activate then current_room:activate() end
end

Hey, I noticed a typo:

49. Create a Stage room that has no Area in it. Create a Circle object that does not inherit from GameObject...

from blog.

That isn't a typo.

from blog.

Isn't it? In answers You say that it is required for Circle to inherit from GameObject

As required, it inherits from GameObject, receives an area, position and optional arguments as arguments.

Edit: clarification

from blog.

Oh, sorry, I didn't notice that these are two different exercises.
