Method Detail

getType

public Shape.Type getType()

Get the type of the child shape. You can use this to down cast to the concrete shape.

Returns:

the shape type.

getShape

public Shape getShape()

Returns the shape of this fixture

setSensor

public void setSensor(boolean sensor)

Set if this fixture is a sensor.

isSensor

public boolean isSensor()

Is this fixture a sensor (non-solid)?

Returns:

the true if the shape is a sensor.

setFilterData

public void setFilterData(Filter filter)

Set the contact filtering data. This will not update contacts until the next time step when either parent body is active and awake. This automatically calls Refilter.

getFilterData

public Filter getFilterData()

refilter

public void refilter()

Call this if you want to establish collision that was previously disabled by b2ContactFilter::ShouldCollide.

getBody

public Body getBody()

Get the parent body of this fixture. This is NULL if the fixture is not attached.

testPoint

public boolean testPoint(Vector2 p)

Test a point for containment in this fixture.

Parameters:

p - a point in world coordinates.

testPoint

public boolean testPoint(float x,
                         float y)

Test a point for containment in this fixture.

Parameters:

x - the x-coordinate

y - the y-coordinate

setDensity

public void setDensity(float density)

Set the density of this fixture. This will _not_ automatically adjust the mass of the body. You must call b2Body::ResetMassData to update the body's mass.

getDensity

public float getDensity()

Get the density of this fixture.

getFriction

public float getFriction()

Get the coefficient of friction.

setFriction

public void setFriction(float friction)

Set the coefficient of friction.

getRestitution

public float getRestitution()

Get the coefficient of restitution.

setRestitution

public void setRestitution(float restitution)

Set the coefficient of restitution.

setUserData

public void setUserData(Object userData)

Sets custom user data.

getUserData

public Object getUserData()

Returns:

custom user data
