Hey! A few days ago I asked for help on how to make a system to save 'states' for various instances that have been changed by the player, like in a dungeon crawler if the player break a crate or open a chest, to then go down to a new floor, and then back up to the previous one again, and how to make the crate stay broken and the chest stay open. I got excellent help from the forum, and now I need help with something similar. Now, in the dungeon crawler I'm making it's possible to throw items on the ground, but if I throw a sword on the ground, then go down to a new floor and then again goes back up to the previous floor, that sword will be gone as it has been removed :/ does anyone have any good suggestions on how to save and then regenerate the same object at the same position?? Suggestion: Just before going to a new floor a system will loop through all instances under parent_item and give them an id, similar to what I've done with the previous problem, which was fixed with PixelatedPope's tutorial: Spoiler: Tutorial Basically a string combined with what floor you're on + the object index + x position + y position, which will almost in all cases, even in a randomly generated dungeon, give a fully unique id. Then save all the id's of all the item instances as well as count how many items that are saved, in a file. Upon going back to a floor with items that should be regenerated, or when restarting the game, there gotta be a system that will loop through a instance_create loop that will go through all the saved id's and generate instances based on what's saved in that id. I bet this could be done if it's possible to refer to certain positions in a string (?) like from postion 1 to position 2 ? A id created using this system can look something like 2obj_itmdrp_ironsword400300 where 2 is the floor it was generated on, obj_itmdrp_ironsword is the object index, 400 is the x and 300 is the y. With this it should be possible to fill in the needed information to a instance_create function? but I'm not sure how to do it. If there's a Game Maker guru out there that might have suggestions to this I'd be happy Thanks!
