The time it takes to excavate an infinitesimal element is proportional to the size of the element and its depth. To mine the next unit, the mine must excavate from depth 304920 (= 11 / 13 If a triangle had the initial amount 13 of the resource and 2 units are remaining, the 11 shallowest height levels have already been excavated. When mining the second unit, the mine excavates from depth 24024 (= 1 / 15 When mining the first unit, the mine excavates from depth 0 (= 0 / 15 This means that if a triangle has the capacity 1 and the amount 1 of its resource, the whole depth must be excavated to mine the unit of resource.īut if a triangle has the capacity 15 of its resource, only 1/15th of the depth must be excavated to mine each unit of resource on the triangle. When the resource amount of a triangle equals the capacity (in other words, the triangle is full of resource), the resource amount is considered uniformly distributed across all depth levels. 13), which is chosen to ensure that all depth calculations can be done with (unsigned 64 bit) integers.Concentration is represented by the capacity and depth is represented by the amount.ĭepth is counted on a scale from 0 to 360360 (= lcm (1., 15) = 23 Realism in mining is achievable insofar that mining high concentrations can be made more rewarding than mining low concentrations and mining deep can be made more expensive than mining shallow. Hunting predators may increase its regeneration rate. Suppose that there is a resource capercaillie. There could also be human activity that increases the resource amount. The resource amount may decrease as a result of mining, fishing, harvesting and so on. Man-made dynamics are when the resource amount is changed as a result of human activity. The resource type and capacity are static while the amount is dynamic. That there are can be more than 16 different resource types per terrain type.That the resource amount is more than 15.How the resource amount is distributed over the depth.That there are several different kinds of resources on a particular triangle,.It is not possible to represent any of the following: The drawback is that the model has the following limitations. This uses 12 bits per triangle which means 3 bytes per node, which is rather efficient. 15) indicating the kind of resource that the triangle has, a capacity (0. (For example the resource fish can only be on the terrain type water.)Įach triangle stores a resource index (0. Resource types are limited to certain terrain types. Resources are located in the triangles of the game's map. The goal of the model is to achieve reasonable realism while being efficient enough to be used in a real time simulation game. It was written in the C++ programming language using the SDL or Allegro library.This document presents a model for resource dynamics. OpenTTD has many improvements over its inspiration, TTD, such as larger maps and online multiplayer play. Some GNU/Linux distributions already have packages for these, but if not, these can be downloaded and installed in-game from the extensions menu. There are official libre data sets for the graphics (OpenGFX), sounds (OpenSFX) and music (OpenMSX). The game project has free/libre media files. Īt this time (February 2022), proprietary data files from the original TTD are not required to play the binary packed game. The game's source code is licensed under the terms of the GNU General Public License version 2.0. OpenTTD is a simulation game for transportation and a clone of the proprietary game Transport Tycoon Deluxe ("TTD"). This article has reached Featured Article status, which means that it has been recognized as one of the best articles on Libregamewiki. The game is completely translated in four languages, and for ten more languages translation is more than ⅔ complete. The latest release of Widelands is version 1.1 released on October 23 rd, 2022. It supports online play via their own meta-server as well as LAN and direct IP connection. Widelands has single-player campaigns as well as multi-player. The source code and media are licensed under the GNU General Public License. It uses the Simple DirectMedia Layer and is written in the C++ programming language.
