      Download the Game Design and Indie Game Marketing Freebook   07/19/17

      GameDev.net and CRC Press have teamed up to bring a free ebook of content curated from top titles published by CRC Press. The freebook, Practices of Game Design & Indie Game Marketing, includes chapters from The Art of Game Design: A Book of Lenses, A Practical Guide to Indie Game Marketing, and An Architectural Approach to Level Design. The GameDev.net FreeBook is relevant to game designers, developers, and those interested in learning more about the challenges in game development. We know game development can be a tough discipline and business, so we picked several chapters from CRC Press titles that we thought would be of interest to you, the GameDev.net audience, in your journey to design, develop, and market your next game. The free ebook is available through CRC Press by clicking here. The Curated Books The Art of Game Design: A Book of Lenses, Second Edition, by Jesse Schell Presents 100+ sets of questions, or different lenses, for viewing a game’s design, encompassing diverse fields such as psychology, architecture, music, film, software engineering, theme park design, mathematics, anthropology, and more. Written by one of the world's top game designers, this book describes the deepest and most fundamental principles of game design, demonstrating how tactics used in board, card, and athletic games also work in video games. It provides practical instruction on creating world-class games that will be played again and again. View it here. A Practical Guide to Indie Game Marketing, by Joel Dreskin Marketing is an essential but too frequently overlooked or minimized component of the release plan for indie games. A Practical Guide to Indie Game Marketing provides you with the tools needed to build visibility and sell your indie games. With special focus on those developers with small budgets and limited staff and resources, this book is packed with tangible recommendations and techniques that you can put to use immediately. As a seasoned professional of the indie game arena, author Joel Dreskin gives you insight into practical, real-world experiences of marketing numerous successful games and also provides stories of the failures. View it here. An Architectural Approach to Level Design This is one of the first books to integrate architectural and spatial design theory with the field of level design. The book presents architectural techniques and theories for level designers to use in their own work. It connects architecture and level design in different ways that address the practical elements of how designers construct space and the experiential elements of how and why humans interact with this space. Throughout the text, readers learn skills for spatial layout, evoking emotion through gamespaces, and creating better levels through architectural theory. View it here.

SDL via C#

4 posts in this topic

Any recommendations for using SDL through C#? I saw SDL.NET and plan to give that a try. Anyone have and quick tips before I begin?

That's what I'm doing, except that I'm using the Tao.Sdl wrapper. The Tao library is just a direct wrapper; it has the same functions and constants, all in the Sdl class.

SdlDotNet is much higher level. I actually prefer the Tao wrapper because I'm making an implementation-independant wrapper anyway. (I'll have a dll for pure winforms, a dll for SDL+OpenGL, and possibly others.)

From what I remember of my time using it it's a nice library.

One thing, though: I'm not sure whether it runs on Mono/Linux. I know the Tao libraries do, though.

I am the developer and maintainer of SdlDotNet. A good tip is to check out the examples. They give you a feel for how the event loop and display methods (blit, flip, setvideo) interact. There is some documentation as well. Thanks for using the library and please post any of your feedback.

Ohh I just may have to learn C# and give that product a try now [smile] Good to know creators are active with their creations on the forum.

Also, you may want to check out my library. It has a somewhat different purpose than SDL.NET, but there is much overlapment.

Managed Game Library (ManagedGL)

I'd shoot for the last 1.x beta (0.x that is), the 2.x betas are still under heavy development.

/edit:
If you are using (or planning to use) Visual C# Express 2005, you might as well go with the 2.0 beta (found as the 1.9x series). It has some nice .NET 2 additions you might want to see!

/edit2:

See this code as example for the 2.0 versions. Note the use of so-called Surface Chains, which allows you to automate certain surface processes, such as:

load->colorkey->convert

so that you can run them with a single call to the chain.


#region Using directives

using System;
using System.Drawing;
using System.Collections.Generic;
using System.Text;

using ManagedGL;
using ManagedGL.SurfaceProcessors;

#endregion

namespace ManagedGL_2_Test
{
class Program
{
bool quit = false;

BlitData backblit;
BlitData test1blit;
BlitData test2blit;

void Run()
{
// create a new window, 800x600x32 not fullscreen
MainWindow wnd = new MainWindow(new Size(800, 600), 32, false);
wnd.SetKeyRepeat(500, 5);
wnd.Text = "Welcome to ManagedGL 2.0";
wnd.Quit += new EventHandler(wnd_Quit);
wnd.KeyDown += new EventHandler<KeyEventArgs>(wnd_Key);

// setup a loader chain
SurfaceLoader loader = new SurfaceLoader();
ProcessChain loadChain = new ProcessChain();
loadChain.Add(loader);
SurfaceColorkeyer colorkey = new SurfaceColorkeyer(Color.FromArgb(255, 0, 255));
loadChain.Add(colorkey);
loadChain.Add(new SurfaceConverter(wnd.Format));
loadChain.AutoDispose = true;

// load test1.bmp
loader.Filename = "../data/test.bmp";
Surface test1 = loadChain.Process();

// load test2.bmp
loader.Filename = "../data/test2.bmp";
Surface test2 = loadChain.Process();

// remove the colorkeying and load the background
loader.Filename = "../data/back.bmp";
loadChain.Remove(colorkey);
Surface back = loadChain.Process();

// setup a single blit process with data for the three images
SurfaceBlitter blitter = new SurfaceBlitter();
backblit = new BlitData(wnd, new Point(0, 0));
test1blit = new BlitData(wnd, new Point(0, 0));
test2blit = new BlitData(wnd, new Point(400, 300));

while(!quit)
{
// blit the images
blitter.Data = backblit; blitter.Process(back);
blitter.Data = test1blit; blitter.Process(test1);
blitter.Data = test2blit; blitter.Process(test2);

// update the window
wnd.Update();
wnd.UpdateEvents();
}
}

void wnd_Quit(object sender, EventArgs e)
{
quit = true;
}

void wnd_Key(object sender, KeyEventArgs e)
{
switch(e.Key.Name)
{
case KeyName.Left: test1blit.Destpoint.X -= 3; break;
case KeyName.Right: test1blit.Destpoint.X += 3; break;
case KeyName.Up: test1blit.Destpoint.Y -= 3; break;
case KeyName.Down: test1blit.Destpoint.Y += 3; break;
}
}

public static void Main(string[] args)
{
(new Program()).Run();
}
}
}
