Bleach:Zanpakutou Senshi is a totally free Total Conversation of Half-Life 1. It´s based on the japanese hit Anime Bleach.
One of the ranged attacks for Grimmjow will be a cero beam.
In this approach I prepared the other parts of the game behaviour to be prepared for the implementation of the beam, such as preventing the player from moving while shooting the beam and allowing the player to disengage the attack and regain movement. The rotation of the player's aim will also be locked.
In the video you see multiple Cero's being fired rapidly and automatically. The concept is to create a dynamical beam linked by small attacks, but appearing as a single beam.
The reason behind this approach is described in: Moddb.com
