Always LOOK when you re-enter the room

[drrak]

Translator:
Great engine. I like everything very much, except for the abbreviated description after re-entering a previously visited room. Because of this, I often have to enter LOOK.

Can this be easily changed?

If your use case is to print the full description when entering a room, could use the onEnter hook? Like so:

{
    id: 'roomid',
    name: 'Room Name',
    desc: `Long description of the room`,
    onEnter: () => {
        const room = getRoom('roomid')
        if(room.visits > 1) {
            println(room.desc)
        }
    }
}

On the first visit, the description will be printed by the engine. On successive visits, the description will be printed by this onEnter hook.

In order to apply it to each room, you would have to copy this to each room's onEnter or send the disk/rooms through a function to apply it programmatically.

Hi, thank you for your question and very glad you like the engine!

There are a number of ways to tackle this. @dthigpen's recommendation above is one way. The upside to this approach is that it doesn't change anything about how the engine works, which is a less brittle approach (because if the engine changed, your adaption might break). The downside is that it isn't very DRY (as in "don't repeat yourself"). I should note here I'm referring to the idea of updating each room manually to do this. The suggestion of applying this change programmatically would certainly DRY it up.

Another approach which would be more DRY but also more brittle would be to override the enterRoom command. You would only have to do this in one place rather than for every room. You might first capture how enterRoom is working in another variable, then override it to add this functionality like so:

const defaultEnterRoom = enterRoom;
enterRoom = (id) => {
  defaultEnterRoom(id);
  const room = getRoom(id);
  if(room.visits > 1) {
    println(room.desc)
  }
};

Another way which is more brittle but also dead simple would be to simply change the enterRoom method in the engine itself. You would just comment out lines 972 and 974, disabling the if statement around the line that prints the description:

 // if (room.visits === 0) {
    println(room.desc);
 // }
