<h2>Additions to the NewGRF Road Stops Specification in JGR's Patchpack in NML</h2>
|
|
<p>This document describes the non-standard additions to the NewGRF road stops feature in the <a href="https://newgrf-specs.tt-wiki.net/wiki/NML:Main">Official OpenTTD NML Specifications</a>, as implemented in this patchpack, and the associated <a href="https://github.com/JGRennison/nml">NML fork</a><br />
|
|
The additions here are compatible with the specification and OpenTTD 14.0, such that GRFs can run on OpenTTD 14.0 and also optionally use patchpack extensions where available.</p>
|
|
<p>These additions and the official specification do not match the obsolete OpenTTD PR #7955 which used a different NewGRF interface.</p>
|
|
|
|
<p>The feature identifier is <span class="code">FEAT_ROADSTOPS</span>, (the PARENT scope for this feature is the road stop's station's town).<br />
|
|
There is no permanent storage associated with this feature.</p>
|
|
|
|
<p>See the <a href="newgrf-additions-nml.html">NewGRF additions (NML)</a> document for background information on additions to NML.</p>
|
|
|
|
<p>See the associated <a href="newgrf-roadstops.html">non-NML document</a> for more details on the NewGRF road stops feature.</p>
|
|
|
|
<p>This feature will be automatically skipped when loaded into a version of OpenTTD which does not support this feature (before 14.0).<br />
|
|
If this feature is the only significant thing in this GRF, then <span class="code">version_openttd(14, 0) || extended_feature_test("road_stops")</span> MAY be called and some message, error or other form of
|
|
signalling to the user used to inform the user that this version of OpenTTD does not support the feature, if the value is false.</p>

<h3 id="roadstop_ids">Road Stop IDs</h3>
|
|
<p>
|
|
A road stop is allocated by setting the 'class'-property, which should therefore be set first.<br />
|
|
Road stop IDs are NewGRF-local and can be freely chosen in the 0..63999 range, as of version 7 of the <span class="code">road_stops</span> feature.<br />
|
|
When loaded into a version of OpenTTD with versions 1 to 6 of the <span class="code">road_stops</span> feature, IDs are limited to the range: 0..254.
|
|
Any road stops with IDs outside this range will be skipped.
