Info

• Editing a non-transparent sprite will no longer sometimes turn it transparent in the preview. • Solved a bug in collision checking with scaled instances. • Solved a bug in collision checking with e.g. lines and rectangles that were not on integer coordinates. • Function file_bin_open now create the file if it does not yet exist. • Added checks in the object_set_parent function to avoid cycles. • Solved an error in the bounce action with diagonal bounces. • Corrected a bug in the rain effect when the room was higher than 1000 pixels. • Corrected a bug that instances without sprites would contstantly get Outside Room events. • Corrected a bug when dragging actions between Object and Timeline form (it is no longer possible). • Increase the minimal height of the background form to make it impossible to hide the OK button. • Corrected a bug with addressing variables in an instance after it changed object during the same step. • Corrected a bug that (de-)activating instances without a sprite could work wrong. • Corrected an error in drawing a path with 0 length. • Solved a bug that the Exit Event action inside a Repeat block did not exit the event. • Corrected the position of the loading bar for the game. • Corrected an error in removing instance outside a room in the room editor. • ... Using Game Maker Game Maker is an easy to use program for creating your own computer games. This section of the help file gives you all the information you need for creating your first games. Later sections will discuss more advanced topics, how to finish and distribute your game, and the built-in programming language GML. So you want to create your own computer games
Playing computer games is fun. But it is actually more fun to design your own computer games and let other people play them. Unfortunately, creating computer games is not easy. Commercial computer games you buy nowadays typically take one to three years of development with teams of anywhere between 10 and 50 people. Budgets easily reach millions of dollars. And all these people are highly experienced: programmers, art designers, sound technicians, etc. So does this mean that it is impossible to create your own computer games? Fortunately no. Of course you should not expect to create your own Quake or Age of Empires within a few weeks. But that is also not necessary. Simpler games, like Tetris, Pacman, Space Invaders, etc. are also fun to play and a lot easier to create. Unfortunately they still require good programming skills to handle the graphics, sounds, user interaction, etc. But here comes Game Maker which was written to make it a lot easier to create such games. There is no need to program. An intuitive and easy to use drag-and-drop interface allows you to create your own games very quickly. You can import and create images, sprites (animated images) and sounds and use them. You can easily define the objects in your game and indicate their behavior, and you can define appealing rooms with scrolling backgrounds in which the game takes place. And if you want full control there is actually an easy-to-use programming language built into Game Maker that gives you full control over what is happening in your game. Game Maker focuses on two-dimensional games. So it is not meant to create 3D worlds like Quake, even though there is some limited functionality for 3D graphics. But don’t let this put you down. Many great games, like Age of Empires, the Command & Conquer series, and Diablo use two-dimensional sprite technology, even though they look very 3-dimensional. And designing two-dimensional games is a lot easier and faster. Game Maker comes in two editions, the Lite Edition and the Pro Edition. The Lite Edition can be used free of charge but it is limited in its functionality and will display popup messages. You can though freely distribute the games you create with it, you can even sell them if you like. See the enclosed license agreement for more details. You are strongly encouraged to upgrade your copy of Game Maker to the Pro Edition. It will considerably extend the functionality of Game Maker and it will remove the logo when running games. This will also support the further development of Game Maker.
