I've seen some ways of doing this, such as attaching sword to the player and setting the sword's angle.
I don't want to use this method because wouldn't work well in a character with a good resolution, where u can see clearly the details with a bunch of animations.
I thought I could do it using a different animations with weapons and no weapons. For exemple: Idle, idle_Weapon, Running, Running_Weapon, etc...
This way I could explore more the animations quality but then I thought...How do I identify colisions properly if it's all the same thing?So, if I touch the enemy just with the sword, I would take damage.
