Unigine.JointParticles Class
| Inherits from: | Joint |
This class is used to pin cloth body or rope body to rigid bodies, ragdolls or dummy bodies.
Example#
The following code illustrates connection of a rope body (rope) and a dummy body (dummy) using a particles joint. The anchor is placed at the position of a dummy body.
Source code (C#)
//the anchor point is placed at the position of a dummy body, pinning area size is (0.5f, 0.5f, 1.5f)
JointParticles joint = new JointParticles(dummy, rope, dummy.Object.Position, new vec3(0.5f, 0.5f, 1.5f));
// setting pinning threshold
joint.Threshold = 0.001f;
// setting number of iterations
joint.NumIterations = 4;See Also#
Usage examples:
JointParticles Class
Properties
int NumParticles#
The total number of pinned particles of the cloth or rope body.
float Threshold#
The threshold that determines the distance for pinning vertices of cloth or rope body to another body. If vertices are closer than the threshold, they are pinned together; otherwise, particles stay loose.
vec3 Size#
The size of the area of pinned vertices of cloth or rope body to another body.
Members
JointParticles ( ) #
Constructor. Creates a particle joint with an anchor at the origin of the world coordinates.JointParticles ( Body body0, Body body1 ) #
Constructor. Creates a particle joint connecting two given bodies. An anchor is placed in the center of the body to which the cloth or rope is pinned.Arguments
- Body body0 - First body to be connected with the joint. It can be one of the following:
- Body body1 - Second body to be connected with the joint. It can be one of the following:
JointParticles ( Body body0, Body body1, vec3 anchor, vec3 size ) #
Constructor. Creates a particles joint connecting two given bodies with specified pinning area size and an anchor placed at specified coordinates.Arguments
- Body body0 - First body to be connected with the joint. It can be one of the following:
- Body body1 - Second body to be connected with the joint. It can be one of the following:
- vec3 anchor - Anchor coordinates.
- vec3 size - Area for pinning vertices of cloth or rope body to another body.
float GetParticleMass ( int num ) #
Returns the mass of the pinned particle of the cloth or rope body.Arguments
- int num - Particle number.
Return value
Particle mass.vec3 GetParticlePosition ( int num ) #
Returns the position of the pinned particle of the cloth or rope body.Arguments
- int num - Particle number.
Return value
Particle position.void ClearParticles ( ) #
Unpins the cloth or rope body completely.Last update:
