3d Sidescroller Blend Space

Hello everybody,

I have watched a lot of RPG videos about the animation blueprints and all of them includes the Blend Space because it wanted to look like the witches’s combat system (I don’t know if that is the name of the game), so i have a question:

Does the 3d Sidescroller’s combat system required such things like that? I want it to be like those old games MMORPG, if you press forward it will show a walking-running animation and if you press to the left or right side it will show the same animation.

What i’m confused is that the blend space is required to make it go from IDLE state to a Walking or Running state? or it’s just for those left forward and right forward?

Thanks for the answer.
