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 |
GetLocalCorners(Canvas)

Returns
| Type | Description |
|---|---|
| Vector3[] | An array of Vector3s that represent the corners of the canvas in local coordinates. |
GetPlane(Canvas)
Convenience method for getting a plane for this canvas in world coordinates.
Declaration

| Type | Name | Description |
|---|---|---|
| Canvas | canvas | The canvas to get the world corners from. |
Returns
| Type | Description |
|---|---|
| Vector3[] | An array of Vector3s that represent the corners of the canvas in world coordinates. |
