Ok, so my little dungeon runner game has its functioning adventurer characters as objects, but unfortunately I'm having trouble figuring how to let the player assemble a party of four of them like I originally intended. I suspect I will need to have a room/menu before the "dungeon" room proper where the player selects which four adventurers will be assigned to an object array that will be used in the subsequent dungeon, but I'm having difficulty finding specifics on how to properly do that in Game Maker Studio 2. Does anyone else have any experience doing this or similar they'd like to share?
EDIT: Teammates don't need to have any AI beyond following behind the "leader"; in fact, the player only controls the head of the party, which they will be able to cycle out with another member in party order during the dungeon run with the press of a single key. I might have only the character the player is controlling take damage as well, but either way each party member has their own individual HP tracks that renders them unusable when it goes below '0'.
