NAME
Box2D::b2MouseJointDef - Mouse joint definition.
SYNOPSIS
my $joint_def = Box2D::b2MouseJointDef->new();
$joint_def->bodyA( $body_a );
$joint_def->bodyB( $body_b );
$joint_def->target( $target );
$joint_def->maxForce( $max_force );
my $joint = $world->CreateJoint( $joint_def );DESCRIPTION
Mouse joint definition. This requires a world target point, tuning parameters, and the time step.
METHODS
new()
Default constructor.
Returns a Box2D::b2MouseJointDef
dampingRatio()
dampingRatio( $dampingRatio )
The damping ratio. 0 = no damping, 1 = critical damping.
Parameters:
float32$dampingRatio(optional)
Returns a float32
frequencyHz()
frequencyHz( $frequencyHz )
The response speed.
Parameters:
float32$frequencyHz(optional)
Returns a float32
maxForce()
maxForce( $maxForce )
The maximum constraint force that can be exerted to move the candidate body. Usually you will express as some multiple of the weight (multiplier * mass * gravity).
Parameters:
float32$maxForce(optional)
Returns a float32
target()
target( $target )
The initial world target point. This is assumed to coincide with the body anchor initially.
Parameters:
Box2D::b2Vec2$target(optional)
Returns a Box2D::b2Vec2
