public static function Slider(position:
Vector3,
direction: Vector3,
size: float,
drawFunc: Handles.DrawCapFunction,
snap: float):
Vector3;
public static Vector3 Slider(Vector3 position,
Vector3 direction,
float size,
Handles.DrawCapFunction drawFunc,
float snap);
Parameters
| position | The position of the current point. |
| direction | The direction of the sliding. |
| size | 3D size the size of the handle. |
| drawFunc | The function to call for doing the actual drawing - by default, it's Handles.ArrowCap, but any function that has the same signature can be used. |
| snap | The snap value (see SnapValue). |
Returns
Vector3 The new value modified by the user's interaction with the handle. If the user has not moved the handle, it will return the same value as you passed into the function.
Description
Make a 3D slider.
This draws a 3D draggable handle on the screen. The handle is constrained to sliding along a direction vector in 3D space.
Slider handle in the Scene view.
Note: Use HandleUtility.GetHandleSize if you want the handle to always remain the same size on the screen.
