How to easily change Default Events to Fit your Needs
If you are familiarized with UE4 and you are a programmer, you have probably thought more than once:
Wouldn’t it be awesome to define my own default events for my awesome actors?
Well, you can. And it’s quite simple once you know how.
Editor Module
Before anything else, this event registration needs to be done though an Editor Module.
There’s a page on the wiki, ‘Creating an Editor Module’ by Karltheawesome, that describes this process very well, just in case you don’t have one on your project.
Registering Default Events
With that being said, the only thing we need to do is to add some changes to our editor module.
MyEditorModule.h
Inside ‘EditorModule.h’ we will only add a function where we will contain all our event registrations
void PrepareAutoGeneratedDefaultEvents();and a macro that allows us to register them
#define RegisterDefaultEvent(Class, FuncName) ...MyEditorModule.cpp
Inside our .cpp file, we will call RegisterDefaultEvent for each event we want to set as default.
RegisterDefaultEvent(AMyActor, MyEvent);//Some examples:
RegisterDefaultEvent(AEnemy, EnteredCombat);
RegisterDefaultEvent(AEnemy, JustDied);
Unregistering Events
Last thing! We must call Unregister function when the module is shutdown to allow the engine to for example hot-reload the plugin.
