GameMaker How to get the number of instances in a different room

[RifleFire]

Hi Everyone,
I am trying to get the number of instances in a room that is not the current room. I am using an array of rooms and say my player is in room[1,2] but i want to display the number of instances in room [2,3]. How can i do this? Thank you all for any help you can give me...

You can't. Have a global array set to the default number of instances in each room. Then as instances are created or destroyed in a room, modify that room's data in the array.

Humm, so there is no function or built-in variable that can do this for me? For example, the built-in variable Instance_Count can't somehow work outside of the current room to give me an instance count of an adjacent room?

Anything in another room isn't loaded to RAM, there is no way you would be able to get that information without hard-saving the instance count to a variable or predetermine it beforehand.
