Description

A Canvas placable element that can be used to modify children Alpha, Raycasting, Enabled state.

A canvas group can be used to modify the state of children elements.

An example of this would be a window which fades in over time, by modifying the alpha value of the group the children elements well be affected. The result alpha will be the multiplied result of any nested groups, multiplied with the canvas elements alpha.

Canvas Groups can also be configured to not block raycasts (anything on the group will not be considerered for graphic raycasting), and whether elements are interactable.

Variables

alpha Set the alpha of the group.
blocksRaycasts Does this group block raycasting (allow collision).
ignoreParentGroups Should the group ignore parent groups?
interactable Is the group interactable (are the elements beneath the group enabled).

Functions

IsRaycastLocationValid Returns true if the Group allows raycasts.
