Syntax
public static class CanvasExtensions
Methods
GetChildRectTransformAtPoint(RectTransform, Vector3, Boolean, Boolean, Boolean)
Gets a child rect transform for the given point and parameters.
Declaration
public static RectTransform GetChildRectTransformAtPoint(this RectTransform rectTransformParent, Vector3 worldPoint, bool recursive, bool shouldReturnActive, bool shouldReturnRaycastable)
Parameters
Type | Name | Description |
---|---|---|
RectTransform | rectTransformParent | The rect transform to look for children that may contain the projected (orthogonal to the child's normal) world point |
Vector3 | worldPoint | The world point |
Boolean | recursive | Indicates if the check should be done recursively |
Boolean | shouldReturnActive | If true, will only check children that are active, otherwise it will check all children. |
Boolean | shouldReturnRaycastable | If true, will only check children that if they have a graphic and have its member raycastTarget set to true, otherwise will ignore the raycastTarget value. Will still allow children to be checked that do not have a graphic component. |
Returns
Type | Description |
---|---|
RectTransform |
