    GameMaker Timers/Alarms, Switches or Global Variables not working (no error messages)

    I'm incredibly inexperienced with Gamemaker - the code I've used is cobbled together from tutorials and the like. I don't know what could be wrong. In the game I'm making, the player is moving into a haunted house. A ghost doesn't want them to so they're throwing furniture at them. I'm trying...

    SOLVED GameMaker is wanting a variable that does not exist to be set.

    A few months ago, I'd been working on a roguelike dungeon crawler sort of game. Although progress was going smoothly, I decided to take an extended break so I could focus on other personal activities. When I came back, after updating the runtime, suddenly the game doesn't want to run for an odd...

    Player Spawning issues with Checkpoint system.

    I sort of solved my problem? I need help understanding. I followed this tutorial to make a checkpoint system in my platformer game. After implementing everything word-by-word, I realized my player wasn't spawning in the spot I designated them to -- instead, they were spawning with the position...

    How to Skip a For Loop Check for a Player not Using a Gamepad?

    Hello, I have a Async gamepad for loop check that checks for connected gamepads and assigns them to one of four player objects. What I would like to do is for the for loop to skip checking for a gamepad if player 1 is just using a keyboard. Since if I left it the way it is, if player 1 is using...

    SOLVED Best Practice For Initializing Global Variables Whilst (almost) Simultaneously Reading Them From an INI file?

    What is the best practice for initializing global variables when also (almost simultaneously) reading them from an INI file? For example, I have an object called 'obj_first_room_controller', where I am initializing global variables at the start of the game in the Create Event. I also have code...

    Is there any difference between 1 object with all global variables vs. many objects with a few global variables each?

    Pretty much what the title says. 1 object with 1000 global variables initialized on game start VS. 100 objects with 10 global variables initialized on game start. Any difference?

    Can anyone help me? I'm about halfway through GMwolfs video and followed the steps but it is not writing any data into the save file.

    GameMaker Keeping variables between rooms - only Global Variables and Persistent Objects?

    I'm trying to do something very simple - I want to talk to an NPC, and then have them say something else after you talk to them the first time, even after you leave and return to the room they're in. Now I know I can keep track of the variable that changes this with a Global Variable or by...

    Is there a place to initialize global variable for debugging and testing purposes? I read some of the other posts about having an initialization room before the game starts, but right now my rooms aren't in order. If I just always start debugging from that room it messes up the order of my non...
