<span class="anchor" id="line-107"></span><span class="anchor" id="line-108"></span><p class="line862">Functions can be executed, or called, from the map or from within the script. To call functions from a map, use an entity that supports the call keypair and assign it a function. Typically, triggers are what support the call function, though there are other cases. To call the <tt class="backtick">simpleFunction</tt> example above, you could enable a <a href="./Entity_TriggerOnce.html">trigger_once</a> with the following keypair: <span class="anchor" id="line-109"></span><span class="anchor" id="line-110"></span><p class="line867"><tt class="backtick">call simpleFunction</tt> <span class="anchor" id="line-111"></span><span class="anchor" id="line-112"></span><p class="line874">Triggers that fire more than once will call their functions each time they fire. Be wary of this when you set up your triggers. <span class="anchor" id="line-113"></span><span class="anchor" id="line-114"></span><p class="line862">To have a function called from within script, see the <a href="./AdvancedScriptTutorial.html">AdvancedScriptTutorial</a>. <span class="anchor" id="line-115"></span><span class="anchor" id="line-116"></span><p class="line867">
