Detailed Description

The abstract base class for a number of CollisionHandlers that have some physical effect on their moving bodies: they need to update the nodes' positions based on the effects of the collision.

Member Function Documentation

◆ addCollider() [1/2]

addCollider ( const NodePath  collider,
const NodePath  target 
)

Adds a new collider to the list with a NodePath that will be updated with the collider's new position, or updates the existing collider with a new NodePath object.

◆ addCollider() [2/2]

addCollider ( const NodePath  collider,
const NodePath  target,
DriveInterface  drive_interface 
)

Adds a new collider to the list with a NodePath that will be updated with the collider's new position, or updates the existing collider with a new NodePath object.

The indicated DriveInterface will also be updated with the target's new transform each frame. This method should be used when the target is directly controlled by a DriveInterface.

◆ clearCenter()

clearCenter ( )

Clears the center NodePath specified with set_center.

◆ clearColliders()

clearColliders ( )

Completely empties the list of colliders this handler knows about.

◆ getCenter()

const NodePath getCenter ( )

Returns the NodePath specified with set_center, or the empty NodePath if nothing has been specified.

◆ getClassType()

static TypeHandle getClassType ( )
static

◆ hasCenter()

bool hasCenter ( )

Returns true if a NodePath has been specified with set_center(), false otherwise.

◆ hasCollider()

bool hasCollider ( const NodePath  collider)

Returns true if the handler knows about the indicated collider, false otherwise.

◆ hasContact()

bool hasContact ( )

Did the handler make any contacts with anything on the last collision pass? Depending on how your world is setup, this can be used to tell if the handler is out of the world (i.e.

out of bounds). That is the original use of this call.

◆ removeCollider()

bool removeCollider ( const NodePath  collider)

Removes the collider from the list of colliders that this handler knows about.

◆ setCenter()

setCenter ( const NodePath  center)

Specifies an arbitrary NodePath that the handler is always considered to be facing.

It does not detect collisions with surfaces that appear to be facing away from this NodePath. This works best when the collision surfaces in question are polygons.

Member Data Documentation

◆ center

const NodePath center

Returns the NodePath specified with set_center, or the empty NodePath if nothing has been specified.
