The green, yellow, red flags are set to embrace 1, 2, 3 track width sections respectively (track width is more clearly explained in the Distance section below). I'm going to use jp1greenfla.s, jp1yellofla.s, jp1redfla.s to demonstrate how auto-placement uses the gantry.dat to set the gantries in MSTS. We'll now look at each part of the gantry.dat file Each of the major parameters is linked to an explanation of how that parameter works. The basic structure of a gantry.dat file is as tabulated below - xxxx indicates an alphanumeric string is required, nnn indicates a number is required. I'd recommend grabbing a default gantry.dat file and adding sections as required. The file is arranged as a series of nested instructions, so you will need to be careful so that your brackets match up.
The gantry.dat file structure is much the same as many other accessory route files: it is a Unicode text file, so you'll need a Unicode-aware editor such as Wordpad (Notepad in XP only) or my favourite, ConTEXT. The Auto-Placement operation uses data found in the gantry.dat. Overall the advantages far out weigh the minor disadvantages.Īs Jim "Sniper" Ward says ".saves an astonishing amount of time, I wish somebody had thought of this 3 years ago!" Scale Rail users should also note that all gantries will need to be set as terrain objects or else you will have alpha bleed through. Placing shapes away from track edge mean that some shapes may be suspended in mid-air beside embankments or buried in the sides of cuttings. Some limitations: yards cause the Auto-Placement process some problems. There seems to be no limit to the number of Gantry Set entries you can make in the Gantry.dat file and once you have placed the shapes using Auto-Placement you can individually move/rotate or delete shapes without affecting the rest of the route. There is really no limit to the number of uses for the Auto-Placement function. In July 2004 Chris Schwan expanded this, creating tree clumps to populate the fringes of the right-of-way. Though originally designed for overhead gantries and poles, Joseph Realmuto and Wayne Campbell demonstrated a use for making fences in 2002. You can select single shapes that are located on either side of the track or use a single shape that spans the track. The gantry.dat that the Auto-Placement uses allows you to select different shapes for double triple and quadruple or more track sections which the function then places correctly (most of the time). The Auto-Placement menu option in RE is an extraordinarily useful tool which enables you to automatically place gantries or other specified shapes at regular user-determined distances along the edge of tracks within a specified tile, saving you hours and hours of work.
