Unreal Engine 4.x Scripting with C++ Cookbook - Second Edition

How it works...

Action Mappings are single-button-push events that fire off C++ code to run in response to them. You can define any number of actions that you wish in the UE4 Editor, but be sure to tie up Action Mappings to actual key pushes in C++.

You may notice that the Jump function we are calling, when we use our action, already exists when we added a reference to it. That is because the Character class already contains an implementation for it. Note that the default implementation doesn't feel like a usual jump – it's more of a rise and float action.

You can find more information on the Character class and the pre-built functions it has at https://api.unrealengine.com/INT/API/Runtime/Engine/GameFramework/ACharacter/index.html.
