Weapon physcannon

Entity description

The Zero Point Energyfield Manipulator
(Gravity Gun)

A gravity gun, used to manipulate physics objects in the game world.

The Zero-Point Energy Field Manipulator was designed for handling hazardous materials, but the people at Eli's lab mainly used it for heavy lifting and playing "catch".

• The weapon_physcannon does not require any ammunition or recharging. Special interactions between a physics prop and the gravity gun are defined by the physgun_interactions in the model's QC file.

• The weapon_physcannon has two attacks : punt and grab. The effective range of each attack depends largely on the mass of the prop or item model. Some NPCs (antlions and headcrabs) are pushed back by the impact of a punt at close range.

• When placed as an entity the weapon_physcannon's world model (weapons/w_physics.mdl) behaves like a prop_physics until 'picked-up' by a player. (In Half-Life 2: Deathmatch, the player spawns with a gravity gun by default. See also game_player_equip.)

Tip:To upgrade the gravity gun to the blue super gravity gun, you will have to set up an env_global entity to look like this:

Class: env_global
Keyvalues		Comments
Initial State	On	This entity can either be triggered by a TurnOn signal,
Global State to Set	Super phys gun is enabled	or start on by setting its Set Initial State flag.

Tip:If you would prefer a subtle gravity gun to a super gravity gun, see Adnan's Rotational Grav Gun - a 4MB single-player demo mod that simply allows the player to rotate objects held by the Gravgun.
