How to make different animations for different weapons?

Hi, I started to do roguelike game, and I have a problem with weapons. I would like to make a lot of weapons, but I don't want them all to have the same attack animation, for example spear and sword.
Is there an easy way to do this, without making mess in my project?

Unfortunately, there is no easy way to do that.

You might have to make the attack animations for each weapon, in a 3D software like blender, 3dsmax or a software that specialises in 3d animations. Or, you might possibly have to mocap them.
