We call those tiles <em>subTiles</em>. Four of those subTiles are combined together to form a bigger 16px by 16px tile (usually called metaTile). We call these <em>tiles</em>.</p><p>Each map can be up to 64 * 64 tiles big. The map consists of two layers of tiles gMapTop and gMapBottom. To access the map array the tilePos index can be used which goes from 0 to 64 * 64 = 4096. Each value in the <a href="structMapLayer.html#a7e583d6664c9efdfb23af449706edc1e" class="m-doc">MapLayer.mapData</a> is a tileIndex which defined which tile of the tileSet should be used. The tileSet contains tiles from 0 to 2048. Special tileIndex from 0x4000 to 0x4096 can be used to denote special tiles.</p><p>A tile is created from four subTiles. The subTiles for each tile in the tileSet are stored in <a href="structMapLayer.html#a3420add9cf651d5f49565acb30467503" class="m-doc">MapLayer.subTiles</a>. This is loaded for the current area from gAreaTileSets_*. The subTiles can also be flipped or the palette changed. This is stored in bits 0xa to 0xf, see <a href="https://www.coranac.com/tonc/text/regbg.htm#sec-map">https:/<wbr />/<wbr />www.coranac.com/<wbr />tonc/<wbr />text/<wbr />regbg.htm#sec-map</a>.</p><p>Each tile in the tileSet also has a tileType defined. This is stored in <a href="structMapLayer.html#a6135ccbf42c2b5a5783ea7dd8fbc6883" class="m-doc">MapLayer.tileTypes</a> and loaded from gAreaTileSetTypes_*. The inverse dictionary from tileType to tileIndex is stored in <a href="structMapLayer.html#a69ad4f606394acfb3adaead1d9426613" class="m-doc">MapLayer.tileIndices</a>.</p><p>The map also stores the collision for each tile in the tileMap layer in <a href="structMapLayer.html#a7e922468597c823c322b6b5e654a0aaa" class="m-doc">MapLayer.collisionData</a>. By default this is filled from gMapTileTypeToCollisionData based on the tileType of the tiles. But it can also be loaded from gRoomCollisionMap_*. In <a href="structMapLayer.html#a087f30e4bed7bf124aa76e2f737622cb" class="m-doc">MapLayer.actTiles</a> some additional type for each tile is stored which is filled from gMapTileTypeToActTile based on the tileType of the tiles.</p> + </div> + </div> + </div> +</article></main> +<div class="m-doc-search" id="search"> + <a href="#!" onclick="return hideSearch()"></a> + <div class="m-container"> + <div class="m-row"> + <div class="m-col-m-8 m-push-m-2"> + <div class="m-doc-search-header m-text m-small"> + <div><span class="m-label m-default">Tab</span> / <span class="m-label m-default">T</span> to search, <span class="m-label m-default">Esc</span> to close</div> + <div id="search-symbolcount">…</div> + </div> + <div class="m-doc-search-content"> + <form> + <input type="search" name="q" id="search-input" placeholder="Loading …" disabled="disabled" autofocus="autofocus" autocomplete="off" spellcheck="false" /> + </form> + <noscript class="m-text m-danger m-text-center">Unlike everything else in the docs, the search functionality <em>requires</em> JavaScript.</noscript> + <div id="search-help" class="m-text m-dim m-text-center"> + <p class="m-noindent">Search for symbols, directories, files, pages or + modules.
