Platform Effector 2D

Switch to Scripting

The Platform Effector 2D applies various “platform” behaviour such as one-way collisions, removal of side-friction/bounce etc.

Colliders that you use with the effector would typically not be set as triggers so that other colliders can collide with it.

Properties

Property: Function:
Use Collider Mask Should the ‘Collider Mask’ property be used? If not then the global collision matrix will be used as is the default for all colliders.
Collider Mask The mask used to select specific layers allowed to interact with the effector.
Use One Way Should one-way collision behaviour be used?
Surface Arc The angle of an arc centered on the local ‘up’ the defines the surface which doesn’t allow colliders to pass. Anything outside of this arc is considered for one-way collision.
Use Side Friction Should friction should be used on the platform sides?
Use Side Bounce Should bounce should be used on the platform sides?
