Since computers entered the home, there has always been a desire to create games, these started off as simple black and white blocks (ZX81, anyone remember? Well take a look here!) and have progressed through the years to something that is almost lifelike (Half Life 2 anyone?) but writing games like that is no easy task, in order to get the best out of the machine, professional games programmers use low-level languages like C++.
Game Maker (GM) by Mark Overmars bridges the gap between professional games programmer and beginner, it's such an easy program to pick up and use. With the use of Drag & Drop (D&D) icons, a simple game could be created in minutes, but in order to produce a more complex and professional game, you're going to have to use the in built Game Maker Language (GML).
GML is a built in scripting language especially for GM that allows you to produce more complex instructions than D&D allows, but the one drawback is that there is no definite reference explaining thoroughly what each function does. The manual tells you each function along with a brief description, but there are no examples or use of combined functions show.
This is where the GM Knowledge Base comes in, this reference program will go in depth into each and every GML function, as well as examples and the use of combined functions. It will also answer questions that many a game maker has asked time and time again. This reference file is laid out like the GML section of the original manual so you should be familiar as to where particular things are.
Also included are tutorials and programming concepts that experts have put together to help you get the best out of your programming abilities and to help you on your way to creating that perfect game.
