Member Function Documentation

AddBehavior()

void VerletPhysics.VerletWorld.AddBehavior ( IBehavior  behavior )

inline

Add a new behavior.

Parameters

behavior

Behavior

Definition at line 123 of file VerletWorld.cs.

        {
            behaviors.Add(behavior);
        }

CreateLink()

VerletLink VerletPhysics.VerletWorld.CreateLink ( VerletPoint  a, VerletPoint  b, float?  restingDistance = null, float?  minimalDistance = null, float?  maximalDistance = null, float?  tearSensitivity = null, float?  tearSensitivityFactor = null, float?  stiffness = null, float?  width = null, Color?  color = null, bool?  visible = null  )

inline

Create a verlet link.

Parameters

a	First verlet point
b	First verlet point
restingDistance	Resting distance
minimalDistance	Minimal link distance. Use -1 to disable.
maximalDistance	Maximal link distance. Use -1 to disable.
tearSensitivity	Distance required to break the link. Use -1 to create an unbreakable link.
tearSensitivityFactor	Distance factor required to break the link. Use -1 to create an unbreakable link.
stiffness	Stiffness of the link
width	Width of the link
color	Link color
visible	Show link

Returns

Verlet link
