NAME
Box2D::b2FrictionJoint - Provides translational and angular friction.
SYNOPSIS
my $joint = $world->CreateJoint( $joint_def );
$joint->SetMaxForce( $max_force );
$joint->SetMaxTorque( $max_torque );DESCRIPTION
Friction joint. This is used for top-down friction. It provides 2D translational friction and angular friction.
METHODS
GetAnchorA()
Get the anchor point on bodyA in world coordinates. Implements Box2D::b2Joint.
Returns a Box2D::b2Vec2
GetAnchorB()
Get the anchor point on bodyB in world coordinates. Implements Box2D::b2Joint.
Returns a Box2D::b2Vec2
GetMaxForce()
Get the maximum friction force in N.
Returns a float32
GetMaxTorque()
Get the maximum friction torque in N*m.
Returns a float32
GetReactionForce( $inv_dt )
Get the reaction force on body2 at the joint anchor in Newtons. Implements Box2D::b2Joint.
Parameters:
float32$inv_dt
Returns a Box2D::b2Vec2
GetReactionTorque( $inv_dt )
Get the reaction torque on body2 in N*m. Implements Box2D::b2Joint.
Parameters:
float32$inv_dt
Returns a float32
SetMaxForce( $force )
Set the maximum friction force in N.
Parameters:
float32$force
SetMaxTorque( $torque )
Set the maximum friction torque in N*m.
Parameters:
float32$torque
