This function gets information on a room from storage and returns it as a struct. You can choose to exclude information through the given optional arguments.
NOTE The function cannot be used to get the current state of an active room (the current room or an already visited persistent room). In this case it returns the original state of the room.
The room must have been previously created using The Asset Browser or added in-game using room_add.
The format of the returned struct is as follows:
room_info_struct =
{
instances:
[
{/* Instance Info Struct */},
{/* Instance Info Struct */},
],
layers:
[
{
elements:
[
{/* Layer Element Info Struct */},
{
/* Example */
type: layerelementtype_tilemap,
tiles: [/* Tile Map Data */]
}
]
},
],
views:
[
{/* View Info Struct */},
]
}
