class FluidParticle : blaze.collision.shapes.shape.Shape;

A fluid particle

this(bVec2 position, float restitution, float friction);

Constructor

void updatePressure ();

Updates the pressure using a modified ideal gas state equation (see the paper "Smoothed particles: A new paradigm for animating highly deformable bodies." by Desbrun)

void update (TimeStep step, bVec2 gravity);

Updates the particle.

AABB aabb ();

Returns:
the axis aligned bounding box associated with the shape, in reference to the parent body's transform

void updateAABB ();

Update the AABB

bVec2 worldCenter ();

Returns:
The particles position in world coordinates

void setMass (float mass);

Params:

float mass

the new mass of the particle

void addNeighbor (uint ID);

Adds a neighbor to the neighbor list

void addForce (bVec2 force);

Applies a force to the particle

Params:

bVec2 force

the force to apply

bool containsPoint (bVec2 v);

Returns:
false. A particle can't contain a point

float calculateInertia (float m, bVec2 offset);

Calculates the inertia

Params:

float m	ignored
bVec2 offset	ignored

Returns:
0.0f

void applyImpulse (bVec2 penetration, bVec2 penetrationNormal, float rest, float fric);

Applies an impulse to the particle

Params:

bVec2 penetration	the distance and direction of penetration
bVec2 penetrationNormal	penetration, but with a length of 1.0
float rest	the coefficient of restitution
float fric	the coefficient of friction
