Detailed Description

Represents a mouse joint that tries to keep a body at a constant distance from the target. This joint is similar to connecting a spring from from the body to a target whose position can be changed programatically using setTarget.

Constructor & Destructor Documentation

◆ FMouseJoint()

FMouseJoint.FMouseJoint	(	FBody	body,
		float	x,
		float	y
	)

Construct a mouse joint between a body and a target. The constructor automatically sets the anchors of the joint to the center of the body.

Parameters

body	the body to be grabbed by the joint
x	horizontal coordinate of the initial target of the joint
y	vertical coordinate of the initial target of the joint

Member Function Documentation

◆ getAnchorX()

float FMouseJoint.getAnchorX ( )

Get the horizontal coordinate of the anchor point on the body. This position is given relative to the center of the body.

Returns: the horizontal coordinate of the anchor relative to the center of the first body

◆ getAnchorY()

float FMouseJoint.getAnchorY ( )

Get the vertical coordinate of the anchor point on the body. This position is given relative to the center of the body.

Returns: the vertical coordinate of the anchor relative to the center of the first body

◆ getGrabbedBody()

FBody FMouseJoint.getGrabbedBody ( )

Returns the body grabbed by this joint.

Returns: the body grabbed by this joint

◆ getTargetX()

float FMouseJoint.getTargetX ( )

Returns the horizontal target position of the joint.

Returns: horizontal coordinate of the target of the joint

◆ getTargetY()

float FMouseJoint.getTargetY ( )

Returns the vertical target position of the joint.

Returns: vertical coordinate of the target of the joint

◆ releaseGrabbedBody()

void FMouseJoint.releaseGrabbedBody ( )

Releases the body grabbed by this joint.

◆ setAnchor()

void FMouseJoint.setAnchor	(	float	x,
		float	y
	)

Sets the anchor position at which the joint grabs the body. The anchor point is the point used to apply forces in order to move the body.

Parameters

x	the horizontal coordinate of the anchor relative to the center of the body
y	the vertical coordinate of the anchor relative to the center of the body

◆ setDamping()

void FMouseJoint.setDamping ( float damping )

Sets the damping of the spring used to maintain the body and the target together. This property must be set before adding the joint to the world.

Parameters

damping the damping of the spring

◆ setFrequency()

void FMouseJoint.setFrequency ( float frequency )

Sets the frequency of the spring used to maintain the body and the target together. This property must be set before adding the joint to the world.

Parameters

frequency the frequency of the spring

◆ setGrabbedBodyAndTarget()

void FMouseJoint.setGrabbedBodyAndTarget	(	FBody	body,
		float	x,
		float	y
	)

Sets the body grabbed by this joint and the target position.

Parameters

body	the body to be grabbed by the joint
x	horizontal coordinate of the target of the joint
y	vertical coordinate of the target of the joint

◆ setTarget()

void FMouseJoint.setTarget	(	float	x,
		float	y
	)

Sets the target position of the joint. By setting this property everytime the mouse is used we are able to make the body of this joint follow mouse.

Parameters

x	horizontal coordinate of the target of the joint
y	vertical coordinate of the target of the joint
