Making a raycasting engine is not too difficult, but it definitely requires some prior experience with programming. The Buffered Image is what is displayed to the user, and pixels is an array of all the pixels in the image.
In addition to some prior programming experience I also recommend an IDE like Eclipse or Netbeans. The other variables won't really appear again, they are just used to get the graphics and program working properly.
To create the Array List put the following line of code with the variables near the top of the class: Now let's take another detour and set up the Camera class.
The Camera class keeps track of where the player is located in the 2D map, and also takes care of updating the player's position.
At this point the Texture class is done, so I'm going to go ahead and define a few textures that will be used in the final program.
To do this put thispublic static Texture wood = new Texture("res/wood.png", 64); public static Texture brick = new Texture("res/redbrick.png", 64); public static Texture bluestone = new Texture("res/bluestone.png", 64); public static Texture stone = new Texture("res/greystone.png", 64);between the "public class Texture" line and "public int pixels".
Overall, using a buffer strategy just helps the game look better when running.
The main class will handle displaying images to the user, calling on other classes to recalculate what should be displayed to the player, and updating the position of the camera. The code after "pixels =" connects pixels and image so that any time the data values in pixels are changed the corresponding changes appear on the image when it is displayed to the user.It looks like this: The load method works by reading the data from the file that loc points to and writing this data to a buffered image.The data for every pixel is then taken from the buffered image and stored in pixels.In the images I have included 4 textures I found online that I will use in this project. To use these textures I recommend putting them in a folder within the project file.To do this go to the project folder (in eclipse this is located in the workspace folder).
