Actions Documentation
CacheFriendly()
This action returns whether you've turned on a faster mode for the solver.
Return
boolean:
Compare(Libraries.Language.Object object)
This action compares two object hash codes and returns an integer. The result is larger if this hash code is larger than the object passed as a parameter, smaller, or equal. In this case, -1 means smaller, 0 means equal, and 1 means larger. This action was changed in Quorum 7 to return an integer, instead of a CompareResult object, because the previous implementation was causing efficiency issues.
Example Code
Object o
Object t
integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smaller)
Parameters
- Libraries.Language.Object: The object to compare to.
Return
integer: The Compare result, Smaller, Equal, or Larger.
Equals(Libraries.Language.Object object)
This action determines if two objects are equal based on their hash code values.
Example Code
use Libraries.Language.Object
use Libraries.Language.Types.Text
Object o
Text t
boolean result = o:Equals(t)
Parameters
- Libraries.Language.Object: The to be compared.
Return
boolean: True if the hash codes are equal and false if they are not equal.
GetDamping()
This action returns a number that will scale the impulse that will be applied to the objects to separate two objects in collision. If the damping number is less than 1, that means we are allowing some error in the solution of the impulse.
Return
number:
GetErp()
This action returns the Baumgarte factor that is used to make sure we can surely push two colliding objects apart.
Return
number:
GetErp2()
This action returns a factor to multiply to the position error in another action that solves the position error first so that the two objects won't penetrate each other. Then, the other action will also calculate the necessary impulse so that we can get the objects to move with the velocity that we want.
Return
number:
GetHashCode()
This action gets the hash code for an object.
Example Code
Object o
integer hash = o:GetHashCode()
Return
integer: The integer hash code of the object.
GetLinearSlop()
This action returns the likely difference between the penetration in the next time step (if we don't correct the current penetration) and the current penetration.
Return
number:
GetNumberIterations()
This action returns the maximum number of repeats a solver can take to find a solution.
Return
integer:
GetSplitImpulsePenetrationThreshold()
This action returns the maximum penetration two objects can have that we consider as acceptable for simulation.
Return
number:
GetTimeStep()
This action returns the fraction of a physics step that we should update the physics calculation. Time is between 0 and 1.
Return
number:
GetWarmStartingFactor()
This action returns a number that will be multiplied to the impulse that the current object is experiencing at a certain CollisionPoint3D to guess an impulse that will separate the two objects involved in a collision.
Return
number:
