PlayerAbilities.cs
Component attached to a player that provides two abilities, dropping a heavy object onto a targeted game object and activating a temporary shield that increases the player's rigidbody mass. Handles input checks, cooldowns, spawn and network spawn of the heavy object, and shield timing and mass override.
