Dude, not to be mean, but I’ve been seeing three very similar questions of you in the answerhub. Instead of just reposting the same issue again, you should maybe just answer any questions you receive and elaborate on what you’re trying to achieve.
As far as I know, triggering simple attack animations is made with AnimMontages and not with blendspaces. Blendspaces are mainly for things like basic movement animation, where you want to blend multiple animations like move_forward and move_left to blend into some move_forward_left state, depending on movement info of your character. For single actions like a simple attack animation, you would use montages.
Don’t say there isn’t any learning material on this, because that’s just not true.
And please stop reposting and give others a chance to get their questions answered too.
