![]() ![]() ![]() raw hex) and programming languages are different. (And although D arrogantly professed that "the young" dont "have as many preconceived notions of what a programming language is supposed to look like", us oldies have a phrase for that. ![]() However, even a beginning programmer could make a stab at understanding the following language command:Ī simple guess would be "load the variable bc with the value 0001". 01 00 01 is the hex for a really simple command on a particular processor, but without intimate knowledge of that system, and without me saying what processor it is for, then it is frankly unintelligible. It has meanings when interpreted, but it does not visually represent anything other than hex.Įg. The hex used in NFO is just that - hex data. The internal representation would not matter. Yeah, if NFO were a language, it should be capable of being compiled on different systems and have different internal representations. They are 2 separate and distinct things.) When I code a test script, and have to resort to direct hex-coding of the chip-card commands, my script has ceased to be PROGRAMMING, and has become (en)CODING. It is the same as my daily job - reading and interpreting hex data streams for chip payment cards. Doesnt mean he is reading a language -just a hex data stream. (And Dalestan is human and can read hex very well. There is no linguistic component to a single thing in NFO. But all it is interpreting is a stream of data. Unless someone claims that hex is a language lexicon. Click the Go To button, and then click on your first bus station with the special go to cursor. But as it has no programming language lexicon, it isnt a language. In the vehicle window, click the Orders button. Is this NFO, or is this a telephone number? 00 44 19 25 65 75 85. (Passenger trains do not pickup mail, for example, unless you add a mail van). Built in Depots, your vehicles will follow Orders between Stations, and will pickup any available cargo that they are able to carry. They produce your only source of income, and therefore must be deployed on a map to ensure success for your Transport company. Last time I checked, hex was not classed as a language. In OpenTTD, vehicles are what keep your company moving. Hence, it does not qualify as a language. The definition of a particular language consists of both syntax (how the various symbols of the language may be combined) and semantics (the meaning of the language constructs)." "A formal language in which computer programs are written. You will still program in some sort of bytecode, but it is easier to manipulate with words rather than with some hex numbers. But I think that it would be nice if GRFcodec would be able to do this. Perhaps other GRF authors have made up their solution. I myself have made a perl script to convert symbolic names to their numbers by usnig some lookup table like: But essentially NewGRF is only "slightly organized hexdump". They are data that are essentialy some sort of bytecode. NFO is just a stream of numbers that can be interpreted. PRINT, GoSUB, switch, etc.Įven assembler is at a higher level than NFO. It is not a language of semantic symbols eg. For some reason, NFO coders try to claim this. Nobody would ever dream to claim that coding in hex was a "language". It represents nothing, and is therefore NOT a semantic symbol. This is encoded as its hex bytes directly. OpenTTD is not an abbreviation of anything.Richk67 wrote:In the example I gave, the only possible "semantic symbol" is the "DFTL" string.

ExtendĬustomize your OpenTTD experience via community-made mods downloaded through an in-game content service, including real-world vehicles, new industry sets, custom scenarios, and more. Expand stations and build network capacity to keep up with demand and avoid delays. Keep up with technological improvements through the years as towns grow new modes of transport are invented and industries appear, change production, or fail. Replacewhenoldv3.patch (18.2 KiB) This task depends upon. Selection is done by dropdown menu from Replace Vehicle Window, default is to replace immediately (the current way). Assemble a fleet of hundreds of vehicles, transferring cargo as needed in an interconnected, multimodal network with optional cargo destinations. This patch allows to set up autoreplace so that vehicle will be replaced only when it reaches end of its life (or rather time for autorenew, to be precise). Work alone or with friends to complete production chains and transport finished goods to towns. Navigate dense city streets, cross oceans and rivers, and conquer high mountains in one of four climates. BuildĬonnect industries and cities on procedurally-generated maps of up to 4096 x 4096 tiles by building a network of roads, railways, docks, and airports. It is an open-source remake and expansion of the 1995 Chris Sawyer video game Transport Tycoon Deluxe. OpenTTD is a business simulation game in which players earn money by transporting passengers and cargo via road, rail, water, and air. ![]()
