Detailed Description

Circle-shaped model to support collisions.

Note that the shape must be circular, not elliptical. If you want to make an ellipse, you will need to use the PolygonObstacle class.

Unless otherwise specified, the center of mass is as the center.

Member Function Documentation

WheelObstacle * WheelObstacle::create ( )

static

Creates a new wheel object at the origin with no radius.

Returns: An autoreleased physics object

WheelObstacle * WheelObstacle::create ( const Vec2 & pos )

static

Creates a new wheel object at the given point with no radius.

The scene graph is completely decoupled from the physics system. The node does not have to be the same size as the physics body. We only guarantee that the scene graph node is positioned correctly according to the drawing scale.

Parameters

pos	Initial position in world coordinates

Returns: An autoreleased physics object

WheelObstacle * WheelObstacle::create	(	const Vec2 &	pos,
		float	radius
	)

static

Creates a new wheel object of the given radius.

The scene graph is completely decoupled from the physics system. The node does not have to be the same size as the physics body. We only guarantee that the scene graph node is positioned correctly according to the drawing scale.

Parameters

pos	Initial position in world coordinates
radius	The wheel radius

Returns: An autoreleased physics object

void WheelObstacle::createFixtures ( )

overridevirtual

Create new fixtures for this body, defining the shape

This is the primary method to override for custom physics objects

Reimplemented from SimpleObstacle.

float WheelObstacle::getRadius ( ) const

inline

Returns the radius of this circle

Returns: the radius of this circle

virtual bool WheelObstacle::init ( )

inlineoverridevirtual

Initializes a new wheel object at the origin with no size.

Returns: true if the obstacle is initialized properly, false otherwise.

Reimplemented from Obstacle.

virtual bool WheelObstacle::init ( const Vec2 & pos )

inlineoverridevirtual

Initializes a new wheel object at the given point with no size.

The scene graph is completely decoupled from the physics system. The node does not have to be the same size as the physics body. We only guarantee that the scene graph node is positioned correctly according to the drawing scale.

Parameters

pos	Initial position in world coordinates

Returns: true if the obstacle is initialized properly, false otherwise.

Reimplemented from Obstacle.

bool WheelObstacle::init	(	const Vec2 &	pos,
		float	radius
	)

virtual

Initializes a new wheel object of the given dimensions.

The scene graph is completely decoupled from the physics system. The node does not have to be the same size as the physics body. We only guarantee that the scene graph node is positioned correctly according to the drawing scale.

Parameters

pos	Initial position in world coordinates
radius	The wheel radius

Returns: true if the obstacle is initialized properly, false otherwise.

void WheelObstacle::releaseFixtures ( )

overridevirtual

Release the fixtures for this body, reseting the shape

This is the primary method to override for custom physics objects

Reimplemented from SimpleObstacle.

void WheelObstacle::resetDebugNode ( )

overrideprotectedvirtual

Redraws the outline of the physics fixtures to the debug node

The debug node is use to outline the fixtures attached to this object. This is very useful when the fixtures have a very different shape than the texture (e.g. a circular shape attached to a square texture).

Redraws the outline of the physics fixtures to the debug node

The debug node is use to outline the fixtures attached to this object. This is very useful when the fixtures have a very different shape than the texture (e.g. a circular shape attached to a square texture).

Unfortunately, the current implementation is very inefficient. Cocos2d does not batch drawnode commands like it does Sprites or PolygonSprites. Therefore, every distinct DrawNode is a distinct OpenGL call. This can really hurt framerate when debugging mode is on. Ideally, we would refactor this so that we only draw to a single, master draw node. However, this means that we would have to handle our own vertex transformations, instead of relying on the transforms in the scene graph.

Reimplemented from Obstacle.

void WheelObstacle::setRadius ( float value )

inline

Sets the radius of this circle

Parameters

value the radius of this circle
