<p>Copy <a href="/wiki/Saved_Data" title="Saved Data">Saved Data</a> to MC1.18 archive</p> <p><b>New page</b></p><div>&lt;code&gt;SavedData&lt;/code&gt; is an alternative to capabilities that stores data per dimension or globally depending on how the context is passed.<br /> <br /> ==Class Structure==<br /> <br /> The class can be broken down into two important methods:<br /> - &lt;code&gt;save&lt;/code&gt;: Write the data to nbt.<br /> - &lt;code&gt;setDirty&lt;/code&gt;: Tell the game that the data has changed and needs to be saved to file.<br /> <br /> The &lt;code&gt;save&lt;/code&gt; method need to be implemented while &lt;code&gt;setDirty&lt;/code&gt; should be called whenever the data is going to be manipulated. As the class is abstract, it should be subclassed with these three methods implemented.<br /> <br /> ==Attaching to a Level ==<br /> <br /> To attach a Saved Data to a particular level, you must have access to an instance of &lt;code&gt;ServerLevel&lt;/code&gt; or &lt;code&gt;ServerChunkCache&lt;/code&gt;. From there, you can call the method &lt;code&gt;#getSavedData&lt;/code&gt; which will give you an instance of the &lt;code&gt;DimensionDataStorage&lt;/code&gt;: the class that stores all saved data for that particular dimension. You can attach an instance or get the current instance of the data using &lt;code&gt;DimensionDataStorage#computeIfAbsent&lt;/code&gt;. This takes in three arguments: the first to construct a saved data with data already existing in some &lt;code&gt;CompoundTag&lt;/code&gt;, the second to construct a saved data with no existing data, and the third to specify the name of the file to save the data to within the &lt;code&gt;data&lt;/code&gt; folder in the overworld or in the specific dimension of the save.<br /> <br /> Global attachments are the same except that they should only be attached to the overworld as that level will always persist.<br /> <br /> <br /> [[Category:Data Storage/1.18|Category:Data Storage]]</div>
