How can I import an Blender animation for my character?

I can’t import any animations for my Carl-Character. Not even as an .fbx or .blend

Also: how can I replace the weapons but keep the same animation? ex.: I have an animation with a weapon (ex: K98k) and switch the weapon but keep the same animation, so that I don’t have to recreate each animation with the other weapons I have created.
Or that I don’t have to create the animations with Unity, 'cause it’s way to complicated.

Thanks for each comment already. :wink:

Just Nevermind - I got it. :wink:
