- Not to be confused with prop_energy_ball.
prop_combine_ballis a point entity available in the Half-Life 2 series.
A prop that physically simulates as a single rigid body. It can be constrained to other physics objects using hinges or other constraints. It can also be configured to break when it takes enough damage.
- Physics Impact Damage Scale
- Multiplies damage received from physics impacts. 0 means the feature is disabled for backwards compatibility.
- Impact damage type
- If true (1), damage type is sharp and the object can slice others.
- Damaging it Doesn't Push It
- Whether damaging the entity applies force to it.
- Scale Factor For Inertia
- Scales the angular mass of an object. Used to hack angular damage and collision response. Confirm:Doesn't actually affect inertia?
- Mass Scale
- Multiplier for the object's mass.
- Override Parameters
- A list of physics keyvalues that are usually embedded in the model. Format is
- Health Level to Override Motion
- If specified, this object will start with motion disabled. Once its health has dropped below this specified amount, it will enable motion.
- Physics Impact Force to Override Motion
- If specified, this object will start motion disabled. Any impact that imparts a force greater than this value will enable motion.
- Minimum DX Level
- The entity will not exist if the engine is running outside the given range of DirectX Versions. Replaced by SystemLevelChoice from Left 4 Dead onwards.
- Warning: If these are used, the object may break when the user switches their DirectX settings.
- Maximum DX Level
- Minimum CPU Level
- A user with a CPU level lower than this will not see this object rendered in-game. CPU levels are determined by the Effect detail setting.
- Maximum CPU Level
- 0: Default
- 1: Low
- 2: Medium
- 3: High
- Minimum GPU Level
- A user with a GPU level lower than this will not see this object rendered in-game. GPU levels are determined by the Shader detail setting.
- Maximum GPU Level
- 0: Default
- 1: Very low
- 2: Low
- 3: Medium
- 4: High
- Allow Physics Gun
- If set, players cannot use Physics Gun on this entity.
- Sandbox Tool Whitelist
- If set, only given tools can be used on this entity. You need to supply the tool class names, the names of the .lua files of those tools. This also includes the context menu properties!
- 1: Start Asleep.
- 2: Don't take physics damage.
- 4: Debris - Don't collide with the player or other debris.
- 8: Motion Disabled.
- 64: Enable motion when grabbed by gravity gun.
- 128: Not affected by rotor wash.
- 256: Generate output on
- 512: Prevent pickup.
- 1024: Prevent motion enable on player bump.
- 4096: Debris with trigger interaction.
- 8192: Force server-side (Multiplayer only; see
- 1048576: Gravity gun can ALWAYS pick up. No matter what.

- Tell the prop to quit moving. Any physics forces (excluding gravity and water buoyancy) will cause the object to resume moving as usual. Sleeping also occurs automatically when the object has no physics forces to keep it awake, and when it is no longer moving a noticeable amount.
- If the object was told to sleep, tell it to start moving again.
- Tell the object to stop moving completely. No physics forces will re-enable motion, not even
- If the object's motion has been disabled entirely, tell it to resume movement as usual. This will also

- If the object would normally float when in water, tell it to not float. There seems to be no way to re-enable floating behavior, but programming a method to do this should be fairly simple (
- Fired when motion has been enabled on the prop, either via the Health Level to Override Motion keyvalue or from the
- Fired when the prop has woken (force has been applied to it while it was asleep, or the
Wakeinput has been called).
- Fired whenever the object is detected to be outside the world. Specifically, it checks if the object is outside of the world's bounding box or if the object is traveling at over 2000 units per second in any cardinal direction.
- Fired when the player has
+used the prop.
Note: This output (but not any of the other pickup-related ones) will fire only if the Generate output on +USE spawnflag is set.
- Fired when the player has dropped the prop (from either
