Physics cannister

Template:Point ent It is a physically simulated gas canister (with a misspelled entity name) that can have its cap shot off, at which point gas will start escaping, causing the canister to fly around. If it takes enough damage, it will explode.

A fire extinguisher turned into a physics_cannister by adding a nozzle attachment to the top. Thrust will be applied along the blue line.

Bug:This entity exists in , but it remains unused and no fitting prop for it exists. It works if a model is added; however, once the thrusting is finished, it interacts glitchily when stood on. It pushes you off the canister prop in unpredictable ways, and the survivor bots keep melee bashing into it when standing nearby.  [todo tested in ?]

Bug:This entity also exists in , also unused and with the default prop missing.

Confirm:is it just as glitchy there as in L4D2?

  [todo tested in ?]

Note:The model should have a nozzle attachment point, which is where gas will escape and thrust will be produced from.
The thrust will be simulated along the Z axis, visualized as the blue line of the attachment in HLMV.

In code, it is represented by theCPhysicsCannisterclass, defined in thephysics_cannister.cppfile.

Keyvalues

Explosion Damage ([todo internal name (i)]) <string>

The amount of damage done by the explosion created when the canister blows up.

Explosion Radius ([todo internal name (i)]) <string>

The radius of the explosion to create when the canister blows up.

Health ([todo internal name (i)]) <integer>

The amount of damage the canister takes before exploding.

Thrust ([todo internal name (i)]) <string>

When the cap has been blown off, and the escaping gas is thrusting the canister about, this is the amount of thrust generated.

Fuel Seconds ([todo internal name (i)]) <string>

The amount of time that gas leaks from the canister before being considered empty.

Smoke Color (R G B) ([todo internal name (i)]) <color255>

Color of the smoke.

Smoke Alpha (0 - 255) ([todo internal name (i)]) <integer 0–255>

Transparency of the smoke.

Thruster Sound ([todo internal name (i)]) <sound>

The sound played when the gas is escaping from the canister.
