<p>See <a href="https://newgrf-specs.tt-wiki.net/wiki/Action14">Action 14 Specification</a> and <a href="https://newgrf-specs.tt-wiki.net/wiki/Action5">Action 5 Specification</a> for background information.</p>
<p>The action 5 type ID mapping mechanism has the feature name: <font face="monospace">action5_type_id_mapping</font>, this document describes version 1.</p>
<p>Users of this mechanism SHOULD at minimum test for the presence of the feature above or test variable 8D, below.</p>
<h4>Action 5 type ID Mapping: C "A5TM"</h4>
<p>Each A5TM chunk (type C) describes an individual action 5 type ID mapping.<br />
Sub-chunks within each A5TM chunk may appear in any order, however except where otherwise noted each sub-chunk SHOULD only appear ONCE within an individual A5TM chunk.</p>
<p>Action 5 type ID mapping can be safely used on implementations which do not implement the type ID mapping mechanism if Action 5 sprites which use mapped type IDs are skipped if one or more of:
<ul>
<li>The global variable 0x8D is checked to determine whether the type ID mapping operation was successful.</li>
<li>The feature name <font face="monospace">action5_type_id_mapping</font> is checked for.</li>
</ul>
Unknown Action 14 blocks are ignored, and do not need to be skipped.</p>
<h4>Property Name: C "A5TM" -> T "NAME"</h4>
<p>Within an A5TM chunk, the NAME text (type T) field contains the name of the type to map. The value of the language ID byte is ignored.</p>
<h4>Property ID: C "A5TM" -> B "TYPE"</h4>
<p>Within an A5TM chunk, the TYPE binary (type B) field contains the type ID to allocate to the named type, this value can used in Action 5 sprites. This is 1 byte. The value MUST be &lt; 128 (i.e bit 7 must be clear).<br />
It is possible to override existing type IDs, however this use is not recommended.</p>
<h4>Success Indicator Global Variable 0x8D Bit: C "A5TM" -> B "SETT"</h4>
<p>This behaves identically to the <a href="#SETT">C "A0PM" -> B "SETT"</a> case, above</p>
<h4>Fallback Mode: C "A5TM" -> B "FLBK"</h4>
<p>This behaves identically to the <a href="#FLBK">C "A0PM" -> B "FLBK"</a> case, above</p>
<h4>Example NFO:</h4>
