The tau cannon world model from Steam versions of the game.

The tau world cannon model from the mod version of the game.

item_weapon_tau is a model entity available in Black Mesa. It is a tau cannon pickup entity, which gives weapon_tau for the player when picked up. It also gives item_ammo_energy (not in Black Mesa (mod)).

Note:Most objects that inherit class CBasePickup in Black Mesa have the following features:

• They're VPhysics objects (disabled in multiplayer mode).
• Respawn in multiplayer mode (item_weapon_ entities creating xen portal effects as well).
• No physics and collision in multiplayer.
• Model can be changed to your own via the parameter (which is not in the FGD by default, added in Enhanced Black Mesa FGD).

Bug:Doesn't collide with other CBasePickup and weapon_ entities (not in ).

Risk of Confusion:Not to be confused with weapon_tau. The key difference between weapon_ and item_weapon_ entities are:

• The respawn mechanics in multiplayer and the respawn sound are different.
• weapon_ physics and collision isn't disabled in multiplayer.
• weapon_ model cannot be changed with properties.
• Different inputs, outputs and flags.
• item_weapon_ can be destroyed by damaging it (nest with snarks only).
• weapon_ are not giving extra ammo.
• Picking up weapon_ with use key will force the player to use it, if the player didn't have the weapon before. Doesn't work with item_weapon_ entities.
