Windows How to go to a Random Room in 8.1

[ApolloStephens]

hey this is my first thread and its just a quick simple question basically I have around 50 rooms and I want have the first room with a button and when I click it I want to go to a random room out of those 50, does anyone know how to code this?

for example I want to click it and randomly be on 23

if anyone can help me that would be great!

A couple ways.

Method 1) Add all your rooms to a global array at the start of the game. When you click on the button, pick a random integer (so if you have 50 rooms, use irandom(49) to pick a random number from 0 to 49). Then goto the room indexed in the array at that number.


room_goto(RoomList[irandom(49)]);


Method 2) Put all your actual game rooms in order. Make sure you're done adding rooms to your game, otherwise you'll have to repeat this process each time you add/remove rooms. Export all the resources in your game to a gmres file. Create a new project. Import that gmres file into the new project. Save the new project. Now do the same thing as above with a random number, but this time add it to the first game room.

room_goto(Level_1 + irandom(49));

@TheouAegis,

How does a script like that looks like? And where do I put it?

Other than what @TheouAegis mentioned:
Suppose you have your room names like this:
room1
room2
room3
....
room50

You can easily access them using asset_get_index.

var roomno = irandom_range(0,50);
var rm_go = asset_get_index("room"+string(roomno));
room_goto(rm_go);

So basically, asset_get_index() converts a string to the asset index. Here, it would take a string (ex, room4) and make it into a usable value so that the actual room can be accessed.

@J.J. In any code where you want the room to change, simple

 

[Roderick]

room_goto(Level_1 + irandom(49))

Does choose() exist in 8.1? If so, you could use

room_goto(choose(level_1, level_2, level_3));

It would get bulky with a large list, but you wouldn't have to worry about forcing the rooms into a specific order.

@matharoo This works like a charm and is really easy also. Clever scripting!

Code:

var roomno = irandom_range(0,50);
var rm_go = asset_get_index("room"+string(roomno));
room_goto(rm_go);

I think it should be
var roomno = irandom_range(1,50);
otherwise you'll get an error if roomno is 0 bij chance

Why? Doesn't it start with room0?

Why? Doesn't it start with room0?

It all depends on your game. room0 or room1, your choice. My code was just a little psuedo-code to explain the concept.

@matharoo, I used the code, but everytime I start the game, the same order of rooms apear in the exact same order everytime.

Do you have a solution for this?

 

[FrostyCat]

Call randomize() at the beginning of your game.

 

[J.J.]

randomize();
var roomno = irandom_range(1,50);
var rm_go = asset_get_index("room"+string(roomno));
room_goto(rm_go);

This is it! Nice '

thank guys!

That's because the random values that come up in a GM game are always the same, unless specified by randomize(), which makes debugging easier.
