![]() ![]() Depotsįollowing the trend for August, another long standing item from the original design was reviewed and discarded. It is even possible to give bypass legs a waiting time, with the train stopping on the tracks for the given time, in case players want to experiment with sidings and timing based flow control. Waypoints have also been added, for example to force trains to take bypass tracks to avoid busy stations. It is also possible to change the default station wait time. The player can then manually tweak the suggested values. In essence it simulates a train on the track every time you click the estimate button. Since this is difficult to estimate by the player, the game offers an automatic calculator, which takes into account things like the speed limit of each track in the line path. This is similar to what happens in real life: line timings never assume trains running at a 100% of the max speed available for a given train and set of tracks. For each leg of the line the player can input a desired travel time, and then the train will try to limit its speed to match it. The most fun feature is the ability to (try to) control train timing. ![]() The lines model is in any case still plenty interesting: This way the schedule can contain multiple lines for the same given train or orders to store in multiple depots, plus handling all the implicit travel to accomplish those tasks. This new design makes it clear a line is just for the commercial passenger service of a train, and the train schedule is for making sure a train as a real time, 24/7 map of what is supposed to be doing at any given time. This is both at a UI level and at a simulation modeling level. Instead of trying to control the 24/7 schedule of a train using the lines interface, I would divide the task in 2 different interfaces. I fought for a couple of weeks with the original design as written more than a year ago, but in the end I realized I needed to compromise and tone it down a notch. But they had a fatal flaw: they were meant to be the highest level of train orders, and as such they had to support features not really related to running a passenger line, like overnight storage. It was a very ambitious design, allowing to set the kind of stop, including stops that were actually guiding the pathfinder like “bypass stops”, or allowing to list a set of platforms in the same station for each stop. It was time to review this prototype code and bring it up with the planned, final lines design. Just like in real life, at the simplest level, they are the sequence of stops that trains must make when they are assigned to them, and so far in-game they were little more that just that, a list of station stops. Lines are the backbone of train circulation in the game. TL DR: near-final lines model with timings and waypoints, depots, mid-level train sim rewrite, train scheduler, more procedural building generation experiments Near-final lines model Internal development notes, very slightly cleaned up and commented a month later. CMD file exampleįollowing is an example of a CMD script to show systems information.NIMBY Rails devblog 2020-08 2 September, 2020 If there is no data group, then the first 256 bytes of the code group will be used instead. They will be populated by CP/M-86 with the zero page. Likewise Program Segment Prefix in DOS, the first 256 bytes of the data group are zero. The start of the header contains the list of the groups present in the file along with their types. cmd extension to save their executable scripts. bat extension today, many people use the. The CMD is a newcomer as compared with BAT file used for MS-DOS before the release of windows In MS-DOS. CMD files can also contain relocation information and Resident System Extensions (RSXs) in its later versions. A CMD file contains 1 to 8 groups of code or data and a 128-byte header. It is generally comparable with COM in CP/M-80 and EXE in DOS. CMD file formatĬMD is a file format used by CP/M-style executable programs. These files are generally written to execute more than one command in a sequence. These files were introduced in the almost in 90’s but still used in the latest Windows operating system. The CMD files are widely used in the Microsoft Windows operating system. It is similar to a BAT file, which is also generally used to store a batch of executable commands. A CMD file consists of a script containing one or multiple commands in the form of plain text that are run in order to execute various tasks. ![]()
