The insane LED Counter & Logic Gates [Part 1]

While browsing tt-forums I stumbled upon a LED Counter created in an OpenTTD game. This is an amazing work because you require a basic knowledge about electronics as well as about OpenTTD and signaling. This work inspired me and I planned to do some other constructions.

Of course this counter is a complex electronic circuit and we should not look at it in a too close manner. It uses half-adders, memory and a lot of logic gates. But some parts, especially the logic gates, are really interesting.
My first intention was to optimize them to be useful in #openttdcoop network games.

Logic Gates – An Overview

Boolean Operators a.k.a. Signals
First of all, we’ll have a look at the requirements to understand logic gates, as I create them, in OpenTTD. A default signal can be either red or green. These two states can be defined as true and false or as 1 and 0 or zero and non-zero or easily as yes and no. In fact, Read the rest of this entry »

The #openttdcoop association

Hello there,

as of today, a new chapter in our community was opened. You probably all noticed the recently added advertisement on our blog page. All out of sudden, some money started to appear in our community’s pockets. In long and exhaustive discussions, we came to the conclusion that it is a good point on which we should take this community to a new level. We concluded that it is best to form a some sort of legal entity. Our choice was to form a swiss “Verein”, according to swiss civil law articles 60ff which we are naming “#openttdcoop association“. It is possible to open bank accounts on the name of the association, enter into contracts and many other things, similar to other legal persons.

Yet Another PBS Patch

Yet Another PBS Patch or in short YAPP is a new engine of pathfinding, which enables trains to share track blocks.
YAPP train leaving station

In this article we wrote about this new engine before and now we are testing it on our Public Server Game 101. Right after our jubilee game a new step in the development of Open TTD. YAPP requires new building techniques as in different signalling and different station entry/ exit layouts. Join us in playing and testing this feature on the public server now!

Public Server Game #100 – A Jubilee

Public Server Game #100 requires OpenTTD 0.4.5, game start was 10.06.08 and the game ended yesterday.

Public Server Game #100 Preview

A little History

These days we are working on Public Server Game #100. This is a real jubilee. The idea of a Public Server was realized back in December 2005. After one year of #openttdcoop having only one Server we introduced the Public Server because there were too many players and new players. We also thought that the building guidelines we used to stick to at the Main Server are very uncomfortable for new players. Read the rest of this entry »
