All other main loop classes are derived from it. Upon application start, a [code]MainLoop[/code] has to be provided to OS, else the application will exit. This happens automatically (and a [SceneTree] is created), unless a main [Script] is supplied, which may or not create and return a [code]MainLoop[/code]. </description> <tutorials> </tutorials> <demos> </demos> <methods> <method name="_drop_files" qualifiers="virtual"> <return type="void"> </return> <argument index="0" name="files" type="PoolStringArray"> </argument> <argument index="1" name="screen" type="int"> </argument> <description> </description> </method> <method name="_finalize" qualifiers="virtual"> <return type="void"> </return> <description> Called before the program exits. </description> </method> <method name="_idle" qualifiers="virtual"> <return type="void"> </return> <argument index="0" name="delta" type="float"> </argument> <description> Called each idle frame with time since last call as an only argument. </description> </method> <method name="_initialize" qualifiers="virtual"> <return type="void"> </return> <description> Called once during initialization. </description> </method> <method name="_input_event" qualifiers="virtual"> <return type="void"> </return> <argument index="0" name="event" type="InputEvent"> </argument> <description> </description> </method> <method name="_input_text" qualifiers="virtual"> <return type="void"> </return> <argument index="0" name="text" type="String"> </argument> <description> </description> </method> <method name="_iteration" qualifiers="virtual"> <return type="void"> </return> <argument index="0" name="delta" type="float"> </argument> <description> </description> </method> <method name="finish"> <return type="void"> </return> <description> </description> </method> <method name="idle"> <return type="bool"> </return> <argument index="0" name="delta" type="float"> </argument> <description> </description> </method> <method name="init"> <return type="void"> </return> <description> </description> </method> <method name="input_event"> <return type="void"> </return> <argument index="0" name="event" type="InputEvent"> </argument> <description> </description> </method> <method name="input_text"> <return type="void"> </return> <argument index="0" name="text" type="String"> </argument> <description> </description> </method> <method name="iteration"> <return type="bool"> </return> <argument index="0" name="delta" type="float"> </argument> <description> </description> </method> </methods> <constants> <constant name="NOTIFICATION_WM_MOUSE_ENTER" value="2"> </constant> <constant name="NOTIFICATION_WM_MOUSE_EXIT" value="3"> </constant> <constant name="NOTIFICATION_WM_FOCUS_IN" value="4"> </constant> <constant name="NOTIFICATION_WM_FOCUS_OUT" value="5"> </constant> <constant name="NOTIFICATION_WM_QUIT_REQUEST" value="6"> </constant> <constant name="NOTIFICATION_WM_GO_BACK_REQUEST" value="7"> </constant> <constant name="NOTIFICATION_WM_UNFOCUS_REQUEST" value="8"> </constant> <constant name="NOTIFICATION_OS_MEMORY_WARNING" value="9"> </constant> <constant name="NOTIFICATION_TRANSLATION_CHANGED" value="90"> </constant> <constant name="NOTIFICATION_WM_ABOUT" value="91"> </constant> <constant name="NOTIFICATION_CRASH" value="92"> </constant> <constant name="NOTIFICATION_OS_IME_UPDATE" value="93"> </constant> </constants> </class>
