I'm working on melee combat system. I don't know how start the block attacks animation. My combat system is inspired by The Witcher 3 combat system. My problem is how can I do the character move his sword to parry the enemy's attacks. My question is about visual aspect. You could see an example video here. Thanks in advance.
It seems you are looking to use an IK setup. This will help to guide your weapon towards a certain point of impact such as another weapon or a shield. Here is a paper describing different melee combat techniques that can be used. Link
