A little project maker for the GameMaker series. Lay out a 2D game on a grid, tick the GML behaviours you want, read a broken GameMaker log and choose the fix, then download real GML event code you can paste straight into GameMaker.
Create, Step and Draw event you can paste into an object. Your work saves automatically.Pick an object below, then click squares on the grid to place it. Put the Player where you start and a Goal at the end. Click a square again, or use the eraser, to remove it.
Each object becomes a shape your GML draws in the Draw event. The mini map below is a bird's eye view of where they sit in the game.
A behaviour is a little block of GML that runs every step. Tick the ones you want and the Studio writes them. Start with Player move so you can move, and Coin collect so collecting does something.
Each ticked behaviour is written into your project's Step_0.gml event.
This is your Create_0.gml event. Every object becomes a row in an array and every ticked behaviour is added to the Step event.
A GameMaker object runs cleanly if all of these are true. The Studio fills most of them in for you.
Create event runs once when the object is made. Set your variables and arrays here.
Step event runs every frame: movement, collisions and score.
Draw event draws your objects with draw_rectangle and draw_text.
Paste them in: make one object (obj_game), open Add Event, and paste each file into its event.
Run it: GameMaker is free to download, press the green Run button.
Click the red line, then choose the fix. Plain lines are normal.
This bundles everything into a zip: Create_0.gml, Step_0.gml, Draw_0.gml and a README. Make one object in GameMaker and paste each file into the matching event.
