How to make a platformer in Gamemaker (the easy way) #2
42This platformer video tutorial series teaches you how to create a platformer in simple steps.
The last video established horizontal movement and sprite changes between two states, idle and moving. Sometimes your player character still gets stuck, as a best practise it is a good idea to seperate the sprite_index which is getting swapped and the collision itself. For that we have one collision mask sprite that we assign to avoid that hassle. And last we establish the vertical movement. So we check if we have ground below the player. If no we fall and set the sprite index to a fall image. If we do have ground below us we enable the player to jump by pressing the space bar.
That's it!
