Unity3D Runtime Transform Gizmos运行时移动、旋转、缩放模型

这款在商店上卖35美元的插件，实用性非常强。

有需要的可以直接在我的CSDN库里下载：

将插件导入，直接打开案例的scene

选中物体，按W、E、R分别切换移动、缩放、旋转操作

所有快捷键的配置如下：

所有的操作入口代码：

public TransformSpace space = TransformSpace.Global;
		public TransformType transformType = TransformType.Move;
		public TransformPivot pivot = TransformPivot.Pivot;
		public CenterType centerType = CenterType.All;
		public ScaleType scaleType = ScaleType.FromPoint;

		//These are the same as the unity editor hotkeys
		public KeyCode SetMoveType = KeyCode.W;
		public KeyCode SetRotateType = KeyCode.E;
		public KeyCode SetScaleType = KeyCode.R;
		//public KeyCode SetRectToolType = KeyCode.T;
		public KeyCode SetAllTransformType = KeyCode.Y;
		public KeyCode SetSpaceToggle = KeyCode.X;
		public KeyCode SetPivotModeToggle = KeyCode.Z;
		public KeyCode SetCenterTypeToggle = KeyCode.C;
		public KeyCode SetScaleTypeToggle = KeyCode.S;
		public KeyCode translationSnapping = KeyCode.LeftControl;
		public KeyCode AddSelection = KeyCode.LeftShift;
		public KeyCode RemoveSelection = KeyCode.LeftControl;
		public KeyCode ActionKey = KeyCode.LeftShift; //Its set to shift instead of control so that while in the editor we dont accidentally undo editor changes =/
		public KeyCode UndoAction = KeyCode.Z;
		public KeyCode RedoAction = KeyCode.Y;

		public Color xColor = new Color(1, 0, 0, 0.8f);
		public Color yColor = new Color(0, 1, 0, 0.8f);
		public Color zColor = new Color(0, 0, 1, 0.8f);
		public Color allColor = new Color(.7f, .7f, .7f, 0.8f);
		public Color selectedColor = new Color(1, 1, 0, 0.8f);
		public Color hoverColor = new Color(1, .75f, 0, 0.8f);
		public float planesOpacity = .5f;
		//public Color rectPivotColor = new Color(0, 0, 1, 0.8f);
		//public Color rectCornerColor = new Color(0, 0, 1, 0.8f);
		//public Color rectAnchorColor = new Color(.7f, .7f, .7f, 0.8f);
		//public Color rectLineColor = new Color(.7f, .7f, .7f, 0.8f);

		public float movementSnap = .25f;
		public float rotationSnap = 15f;
		public float scaleSnap = 1f;

		public float handleLength = .25f;
		public float handleWidth = .003f;
		public float planeSize = .035f;
		public float triangleSize = .03f;
		public float boxSize = .03f;

		public float rotateSpeedMultiplier = 1f;
		public float allRotateSpeedMultiplier = 20f;

		public bool useFirstSelectedAsMain = true;

		//If circularRotationMethod is true, when rotating you will need to move your mouse around the object as if turning a wheel.
		//If circularRotationMethod is false, when rotating you can just click and drag in a line to rotate.
		public bool circularRotationMethod;

		//Mainly for if you want the pivot point to update correctly if selected objects are moving outside the transformgizmo.
		//Might be poor on performance if lots of objects are selected...
		public bool forceUpdatePivotPointOnChange = true;

		public int maxUndoStored = 100;

		public bool manuallyHandleGizmo;

		public LayerMask selectionMask = Physics.DefaultRaycastLayers;

		public Action onCheckForSelectedAxis;
		public Action onDrawCustomGizmo;

		public Camera myCamera {get; private set;}

		public bool isTransforming {get; private set;}
		public float totalScaleAmount {get; private set;}
		public Quaternion totalRotationAmount {get; private set;}
		public Axis translatingAxis {get {return nearAxis;}}
		public Axis translatingAxisPlane {get {return planeAxis;}}
		public bool hasTranslatingAxisPlane {get {return translatingAxisPlane != Axis.None && translatingAxisPlane != Axis.Any;}}
		public TransformType transformingType {get {return translatingType;}}

		public Vector3 pivotPoint {get; private set;}
		Vector3 totalCenterPivotPoint;

		public Transform mainTargetRoot {get {return (targetRootsOrdered.Count > 0) ? (useFirstSelectedAsMain) ? targetRootsOrdered[0] : targetRootsOrdered[targetRootsOrdered.Count - 1] : null;}}

		AxisInfo axisInfo;
		Axis nearAxis = Axis.None;
		Axis planeAxis = Axis.None;
		TransformType translatingType;

		AxisVectors handleLines = new AxisVectors();
		AxisVectors handlePlanes = new AxisVectors();
		AxisVectors handleTriangles = new AxisVectors();
		AxisVectors handleSquares = new AxisVectors();
		AxisVectors circlesLines = new AxisVectors();

		//We use a HashSet and a List for targetRoots so that we get fast lookup with the hashset while also keeping track of the order with the list.
		List<Transform> targetRootsOrdered = new List<Transform>();
		Dictionary<Transform, TargetInfo> targetRoots = new Dictionary<Transform, TargetInfo>();
		HashSet<Renderer> highlightedRenderers = new HashSet<Renderer>();
		HashSet<Transform> children = new HashSet<Transform>();

		List<Transform> childrenBuffer = new List<Transform>();
		List<Renderer> renderersBuffer = new List<Renderer>();
		List<Material> materialsBuffer = new List<Material>();

		WaitForEndOfFrame waitForEndOFFrame = new WaitForEndOfFrame();
		Coroutine forceUpdatePivotCoroutine;

		static Material lineMaterial;
		static Material outlineMaterial;

就连基本的UndoRedo功能都已经做好了。

有了这些基础，去扩展自己的功能那就非常轻松了。

整个工程的地址也上传给有需要的朋友学习。
