SOLVED Creating array of obj position at start of game

[Tonywryip]

My goal: create an array that saves an obj's position in each room at the start of the game so that I can have call it later to have the game remember where the obj was before.

I am using GMS 2

step 1: saving obj position at start of the game

room order is r_menu, r_1, r_2, r_3, and r_4

if room == r_menu {
  
    for (var i = 1; i <= rm_max; ++i) {
        if room == room_last {
            room_goto(r_1);
        } else {
            room_goto_next();
        }
      
        global.rm_pos[i, 1] = room;
        global.rm_pos[i, 2] = o_player.x;
        global.rm_pos[i, 3] = o_player.y;
    }
}

this returns error trying to find o_player which exist in r_1 so I am thinking that it didn't actually go to r_1 but I have room_goto_next() so I am not sure what the problem is here.

and then the next step which I can't test because this step doesn't work goes like this (probably doesn't work

if next_room {
        rm_current = room;
        global.rm_pos[rm_current,2] = x;
        global.rm_pos[rm_current,3] = y;
        if !room_exists(room_next(room)) {
            room_goto(r_1);
            x = global.rm_pos[1,2];
            y = global.rm_pos[1,3];
            rm_current = r_1;
        } else {
            room_goto_next();
            ++ rm_current;
            x = global.rm_pos[rm_current,2];
            y = global.rm_pos[rm_current,3];
        }
    }

any help would be greatly appreciated!

SOLUTION: so turning on room persistent DOES work to keep all the instances in the same place. Although I still haven't figured out why this doesn't work.

Could you do it at the start of each room? I don't think you can go through other rooms without visiting them.

You could also make the room persistent which does the same thing you want. Just without an array.

Ya I've recently changed the code so it doesn't record the x, y position at the start of the game but I still have some problems. (but also I would like to know why this doesn't work ;-; )

the reason I don't want to make the room persistent is that then everything freezes in that room. I want to have things in that room that aren't persistent...

I will try to set the room persistent and instead of adding things to non-persistent rooms I will delete things from the persistent rooms

thanks for the help

No problem. Unfortunately there isn't ever a 100 percent solution to custom problems. But there's almost always a work around.
