CPhysBallSocket defined in physconstraint.cpp
|
phys_ballsocket is a point entity available in all 
Source 2 games. A constraint that keeps the position of two objects fixed, relative to the constraint's origin. You can optionally specify limits for the relative twist and swing rotation.
The joint simulated by phys_ballsocket. Note that Source permits a full 360° of movement since the constraint itself has no physical presence.
Keyvalues
- Friction
(friction)<float> - Resistance/friction in the constraint
- Enable Swing Limit
(enable_swing_limit)<boolean> - Limit relative rotation away from the constraint's Z axis
- Swing Limit
(swing_limit)<float> - Maximum swing angle in degrees, if the swing limit is enabled
- Enable Twist Limit
(enable_twist_limit)<boolean> - Limit relative rotation about the Z axis
- Min Twist Angle
(min_twist_angle)<float> - Minimum relative twist angle in degrees, if the twist limit is enabled
- Max Twist Angle
(max_twist_angle)<float> - Maximum relative twist angle in degrees, if the twist limit is enabled
TwoObjectPhysics:
- Entity 1
(attach1)<targetname>
- Entity 2
(attach2)<targetname> - The entities to constrain. Leave one or the other field blank to constrain to the world.
Note:Only one entity will be constrained, even if several share the given targetname.
- Constraint System Manager
(constraintsystem)<targetname> - A
phys_constraintsystemthat this constraint should be a part of. This avoids the "jiggling" caused by constraints applied to the same set of entities fighting with each other.
- Force Limit to Break
(forcelimit)<float> - Impact force required to break the constraint, in pounds. 0 means infinite. A way of calculating this is to set it to the weight of an object that would break the constraint if it were resting on its objects.
- Torque Limit to Break
(torquelimit)<float> - Torque required to break the constraint, in pounds*inches. 0 means infinite. A way of calculating this is to multiply any reference mass by the resting distance (from the center of mass of the object) needed to break the constraint.
- Play Sound on Break
(breaksound)<string> - A sound played when the constraint is broken.
- Follow teleport distance
(teleportfollowdistance)<float> - If one constrained object teleports more than this many units away, the other will teleport with it.
- Name
(targetname)<string> - The targetname that other entities refer to this entity by.
Flags
- [
1] : No Collision until break
- [
4] : Start inactive
- [
8] : Change mass to keep stable attachment to world
- [
16] : Do not connect entities until turned on
Inputs
TwoObjectPhysics:
Break- Force the constraint to break.
TurnOn- Enable the constraint; do this if the constrained objects don't exist when it spawns. Note that broken constraints cannot be turned back on as they have been deleted.
TurnOff- Disable the constraint.
Base:
RunScriptFile- Load and execute a script file.
RunScriptCode- Execute a fragment of script code.
CallScriptFunction- Call a script function.
CallPrivateScriptFunction- Calls a script function from this entity's private script scope.
CallGlobalScriptFunction- Calls a script function in the global script scope.
Kill- Removes this entity from the world.
KillHierarchy- Removes this entity and all its children from the world.
AddOutput- Adds an entity I/O connection to this entity. Parameter format: OutputName→TargetName→InputName→Parameter→Delay→MaxRefires
FireUser1toFireUser4- Fires the respective
OnUseroutputs; see User Inputs and Outputs.
Outputs
TwoObjectPhysics:
OnBreak- Fired when the constraint breaks.
Base:
OnUser1toOnUser4- These outputs each fire in response to the firing of the like-numbered
FireUser1toFireUser4Input; see User Inputs and Outputs. OnKilled- This output fires when the entity is killed and removed from the game. Parameter is the inflictor.
