Modern 3-dimensional games model the game world with 3-dimensional objects. They use the 3-dimensional graphics hardware to render such scenes. Given a viewpoint, that is, the position from which the player inspects the game world, the hardware creates the correct image taking into account aspects like lighting, hidden surface removal (objects behind other objects cannot be seen and should not be drawn) and atmospheric effects. With the current hardware this can lead to spectacular experiences but there is a price to pay for this. Modeling a 3-dimensional world with 3-dimensional objects and creating the animations for the characters requires a lot of practice and is time consuming | Game Maker Tutorial Adding Depth to Games Written by Mark Overmars Copyright 2007 YoYo Games Ltd Last changed February 23 2007 Uses Game Pro Edition Advanced Mode Level Intermediate Real games are 3-dimensional aren t they Well actually not. All games produce a 2dimensional image on the screen of your computer. They might look 3-dimensional but that does not mean they are 3-dimensional. So what does it mean when a game claims to be 3-dimensional This question is difficult to answer. It is a combination of the way the game is created the visual image the player sees and the way the player controls the game. In this tutorial we will show how to give your games a 3-dimensional look how to add depth in your games. But we won t use the 3D graphics functions for this. We will describe more simple techniques like parallax. scaling transparency and isometric views. Most of this can be achieved by the drag-and-drop actions in Game Maker although at some places we will need a little bit of GML code. To follow the tutorial you should have some experience in the use of Game Maker but you do not need to know GML well. All example games we create in this tutorial are provided in the folder Examples that comes with this tutorial and can be loaded into Game Maker. Also all resources are provided in the folder Resources. Introduction Modern 3-dimensional games model the game world with 3-dimensional objects.
