Believe it or not, there are types of variables than can store more than one value simultaneously, or even other variables. </p><p><br> </p> <h3><span class="mw-headline" id="Container_Variables">Container Variables</span></h3> <p>Container variables are variables that contain other variables within themselves. Just imagine how many variables you could create for information about one unit. There could be a variable my_leader_hitpoints, my_leader_name, my_leader_level, and so on. Instead of having all these different variables, wouldn't it be much easier if we could just put them all in one large box labeled "my_leader"? Well, with container variables, you can! </p><p>Container variables are not restricted to containing scalar variables, however. They can also store other containers or even array variables. </p> <h3><span class="mw-headline" id="Array_Variables">Array Variables</span></h3> <p>You will typically encounter Array variables when you need to store all the units or locations on the map that meet certain criteria. That is outside the scope of this beginner's tutorial, but later you can consult the ReferenceWML documentation for [store_unit] and [store_locations] when you are ready to do that. </p><p><br> Here are some basic facts about Array Variables. Every Array has a length, which is the number of its containers. And these containers are all numbered starting at container zero. </p><p><br> Next Chapter: <a href="https://wiki.wesnoth.org/WML_for_Complete_Beginners:_Chapter_9" title="WML for Complete Beginners: Chapter 9">WML for Complete Beginners: Chapter 9</a> </p><p>Previous Chapter: <a href="https://wiki.wesnoth.org/WML_for_Complete_Beginners:_Chapter_7" title="WML for Complete Beginners: Chapter 7">WML for Complete Beginners: Chapter 7</a> </p><p>Return to Main Index: <a href="https://wiki.wesnoth.org/WML_for_Complete_Beginners" title="WML for Complete Beginners">WML for Complete Beginners</a> </p> <!-- NewPP limit report Cached time: 20211208130606 Cache expiry: 86400 Dynamic content: false CPU time usage: 0.002 seconds Real time usage: 0.003 seconds Preprocessor visited node count: 10/1000000 Preprocessor generated node count: 16/1000000 Post?expand include size: 0/2097152 bytes Template argument size: 0/2097152 bytes Highest expansion depth: 2/40 Expensive parser function count: 0/100 Unstrip recursion depth: 0/20 Unstrip post?expand size: 0/5000000 bytes --> <!-- Transclusion expansion time report (%,ms,calls,template) 100.00% 0.000 1 -total --> </div> <!-- Saved in parser cache with key wiki-mw_:pcache:idhash:5683-0!canonical and timestamp 20211208130606 and revision id 58366 --> </div> <!-- end wikipage --> <div class="printfooter"> Retrieved from "<a dir="ltr" href="https://wiki.wesnoth.org/index.php?title=WML_for_Complete_Beginners:_Chapter_8&amp;oldid=58366">https://wiki.wesnoth.org/index.php?title=WML_for_Complete_Beginners:_Chapter_8&amp;oldid=58366</a>" </div> <div id="catlinks" class="catlinks" data-mw="interface"><div id="mw-normal-catlinks" class="mw-normal-catlinks"><a href="https://wiki.wesnoth.org/Special:Categories" title="Special:Categories">Category</a>: <ul><li><a href="https://wiki.wesnoth.org/Category:WML_for_Complete_Beginners" title="Category:WML for Complete Beginners">WML for Complete Beginners</a></li></ul></div></div><div id="lastmod"> This page was last edited on 18 April 2017, at 03:14.</div> <div class="visualClear"></div> </div> <!-- bodyContent --> </div> <!-- end content --> </div> <!-- end main --> <div id="footer-sep"></div> <div id="footer"><div id="footer-content"><div> <a href="https://wiki.wesnoth.org/StartingPoints">Site Map</a> ? <a href="https://status.wesnoth.org/">Site Status</a><br> Copyright 2003?2021 by <a rel="author" href="https://wiki.wesnoth.org/Project">The Battle for Wesnoth Project</a>.
