Hello everyone, I already downloaded “Punch” animation from Mixamo website, all i want to know is how to Apply this animation whenever i press a Button, For example whenever i left click with my mouse, i want to start “punch” animation on my character so it will look like i’m punching. I searched the internet and didn’t find nothing… If anyone know a good tutorial or something about this, i would be Very happy if you send me the link

this very thing was covered by epic in a video tutorial here. of course there are also other ways to accomplish this same thing but that should get you started
