I'm trying to make a game with some aspects similar to octodad but for this to work I need something that will allow me to move my characters foot in the direction I chose with a key input, it may seem simple but I'm a bit of a noob.
I am new as well. But i am pretty sure you would not create the event in blender, but a game engine.
To explain, in Blender you would create an animation of, lets say a swinging sword, and save that animation to your model.
Now that your model has an animation you would load your model into a game engine (such as Unity or UE4) and in the game engine you would setup your input handler (When i click, play swinging sword animation)
Like I said, I am new as well so I probably need someone to confirm.
