PhysicsContact Class

Module: cc Parent Module: cc

PhysicsContact will be generated during begin and end collision as a parameter of the collision callback. Note that contacts will be reused for speed up cpu time, so do not cache anything in the contact.

Properties

colliderA

colliderB

disabled

If set disabled to true, the contact will be ignored until contact end. If you just want to disabled contact for current time step or sub-step, please use disabledOnce.

disabledOnce

Disabled contact for current time step or sub-step.

Methods

getWorldManifold

Get the world manifold.

getManifold

Get the manifold.

getImpulse

Get the impulses. Note: PhysicsImpulse can only used in onPostSolve callback.

isTouching

Is this contact touching?

setTangentSpeed

Set the desired tangent speed for a conveyor belt behavior.

Parameters

• tangentSpeed Number

getTangentSpeed

Get the desired tangent speed.

setFriction

Override the default friction mixture. You can call this in onPreSolve callback.

Parameters

• friction Number

getFriction

Get the friction.

resetFriction

Reset the friction mixture to the default value.

setRestitution

Override the default restitution mixture. You can call this in onPreSolve callback.

Parameters

• restitution Number

getRestitution

Get the restitution.

resetRestitution

Reset the restitution mixture to the default value.
