Melee shield

[Nihlith]

I've been trying to make a sword and shield. The shields that I have seen elsewhere either summon a virtually indestructible barrier in front of the player, (which is ineffective against melee attacks) or make the player invulnerable (which is not directional). Is there a way to create a shield that is effective against melee attacks but only in one direction? Has someone already made one I could modify with credit attribution?

 

Many thanks to the many good doomers out there.
