Legacy GM Check for a room equal to a variable

[A Random Creator]

Hello GameMaker community!
I don't think that this is possible at all but maybe you guys can figure out a way to do it. I was wondering if it was possible to declare a variable with the names of multiple rooms and check if the room equals to that variable like this for example:

//Create
r = room1, room2, room3

//Step
if(room = r) {
//do something
} else {
//do something else
}

I know that exactly doesn't work but is it possible to do anything like it? If so, let me know, thanks!

this is possible with room as number. Probably with room get name too, but numbers better in most situations.

if room=1 str = 'this is room 1'

if you want names:

var room_name = room_get_name(room);

you can use else and switch of course too, like a:

switch(room)
{
do something
}

on create event you can't declare like this if any. Your r is array, so it should be:

r[0] = room1;
r[1] = room2;
r[3] = room3;

etc

this is theory

Stop thinking in terms of checking against magical "multi-values". Think in terms of checking against a set of values iteratively. This means looping.

Create:

r[0] = room1;
r[1] = room2;
r[2] = room3;

Step:

var rsiz, found;
rsiz = array_length_1d(r);
found = false;
for (var i = 0; !found && i < rsiz; i++) {
  found = room == r[i];
}
if (found) {
  // In given set of rooms
}
else {
  // Not in given set of rooms
}

My advice for novices learning a new programming language: Don't mope over imaginary syntax and how the language won't support it. Think in terms of existing syntax and how it can be applied.

Okay this works perfectly thanks for the help!
