설명

Helper functions for Scene View style 3D GUI.

These are mainly mathematical functions that assist in converting between the 3D Scene space and the 2D GUI. The functions are used in the construction of the Unity Editor itself and so using them is a good way to make your own Handles GUIs consistent with Unity's.

정적 변수

accelerationGet standard acceleration for dragging values (Read Only).
niceMouseDeltaGet nice mouse delta to use for dragging a float value (Read Only).
niceMouseDeltaZoomGet nice mouse delta to use for zooming (Read Only).

정적 함수

AddControlRecord a distance measurement from a handle.
AddDefaultControlAdd the ID for a default control. This will be picked if nothing else is.

ClosestPointToArcGet the point on an arc (in 3D space) which is closest to the current mouse position.
ClosestPointToDiscGet the point on an disc (in 3D space) which is closest to the current mouse position.
ClosestPointToPolyLineGet the point on a polyline (in 3D space) which is closest to the current mouse position.
DistancePointBezierCalculate distance between a point and a Bezier curve.
DistancePointLineCalculate distance between a point and a line.
DistancePointToLineDistance from a point p in 2d to a line defined by two points a and b.
DistancePointToLineSegmentDistance from a point p in 2d to a line segment defined by two points a and b.

DistanceToRectangleReturns the distance in pixels from the mouse pointer to a rectangle on screen.
FindNearestVertexReturns the nearest vertex to a guiPoint within a maximum radius of 50 pixels.
GetHandleSizeGet world space size of a manipulator handle at given position.
GUIPointToScreenPixelCoordinateConverts a 2D GUI position to screen pixel coordinates.
GUIPointToWorldRayConvert 2D GUI position to a world space ray.
PickGameObjectPick game object closest to specified position.
PickRectObjectsPick GameObjects that lie within a specified screen rectangle.
PlaceObjectCasts a ray against the loaded scenes and returns the nearest intersected point on a collider.
PointOnLineParameterReturns the parameter for the projection of the point on the given line.
