Transform

class in UnityEngine

Inherits from:Component

Description 描述

Position, rotation and scale of an object.

Every object in a Scene has a Transform. It's used to store and manipulate the position, rotation and scale of the object. Every Transform can have a parent, which allows you to apply position, rotation and scale hierarchically. This is the hierarchy seen in the Hierarchy pane. They also support enumerators so you can loop through children using:

using UnityEngine;

public class Example : MonoBehaviour
{
    // Moves all transform children 10 units upwards!
    void Start()
    {
        foreach (Transform child in transform)
        {
            child.position += Vector3.up * 10.0f;
        }
    }
}

Properties 属性

	childCount		The number of children the parent Transform has.
	eulerAngles		The rotation as Euler angles in degrees.
	forward		Returns a normalized vector representing the blue axis of the transform in world space.
	hasChanged		Has the transform changed since the last time the flag was set to 'false'?
	hierarchyCapacity		The transform capacity of the transform's hierarchy data structure.
	hierarchyCount		The number of transforms in the transform's hierarchy data structure.
	localEulerAngles		The rotation as Euler angles in degrees relative to the parent transform's rotation.
	localPosition		Position of the transform relative to the parent transform.
	localRotation		The rotation of the transform relative to the transform rotation of the parent.
	localScale		The scale of the transform relative to the GameObjects parent.
	localToWorldMatrix		Matrix that transforms a point from local space into world space (Read Only).
	lossyScale		The global scale of the object (Read Only).
	parent		The parent of the transform.
	position		The world space position of the Transform.
	right		The red axis of the transform in world space.
	root		Returns the topmost transform in the hierarchy.
	rotation		A Quaternion that stores the rotation of the Transform in world space.
	up		The green axis of the transform in world space.
	worldToLocalMatrix		Matrix that transforms a point from world space into local space (Read Only).

Public Methods 公共方法

	DetachChildren		Unparents all children.
	Find		Finds a child by n and returns it.
	GetChild		Returns a transform child by index.
	GetSiblingIndex		Gets the sibling index.
	InverseTransformDirection		Transforms a direction from world space to local space. The opposite of Transform.TransformDirection.
	InverseTransformPoint		Transforms position from world space to local space.
	InverseTransformVector		Transforms a vector from world space to local space. The opposite of Transform.TransformVector.
	IsChildOf		Is this transform a child of parent?
	LookAt		Rotates the transform so the forward vector points at /target/'s current position.
	Rotate		Use Transform.Rotate to rotate GameObjects in a variety of ways. The rotation is often provided as an Euler angle and not a Quaternion.
	RotateAround		Rotates the transform about axis passing through point in world coordinates by angle degrees.
	SetAsFirstSibling		Move the transform to the start of the local transform list.
	SetAsLastSibling		Move the transform to the end of the local transform list.
	SetParent		Set the parent of the transform.
	SetPositionAndRotation		Sets the world space position and rotation of the Transform component.
	SetSiblingIndex		Sets the sibling index.
	TransformDirection		Transforms direction from local space to world space.
	TransformPoint		Transforms position from local space to world space.
	TransformVector		Transforms vector from local space to world space.
	Translate		Moves the transform in the direction and distance of translation.

	tag		The tag of this game object.
	transform		The Transform attached to this GameObject.
	hideFlags		Should the object be hidden, saved with the Scene or modifiable by the user?
	name		The name of the object.

Public Methods 公共方法

	BroadcastMessage		Calls the method named methodName on every MonoBehaviour in this game object or any of its children.
	CompareTag		Is this game object tagged with tag ?
	GetComponent		Returns the component of Type type if the game object has one attached, null if it doesn't.
	GetComponentInChildren		Returns the component of Type type in the GameObject or any of its children using depth first search.
	GetComponentInParent		Returns the component of Type type in the GameObject or any of its parents.
	GetComponents		Returns all components of Type type in the GameObject.
	GetComponentsInChildren		Returns all components of Type type in the GameObject or any of its children.

	SendMessageUpwards		Calls the method named methodName on every MonoBehaviour in this game object and on every ancestor of the behaviour.
	TryGetComponent		Gets the component of the specified type, if it exists.
	GetInstanceID		Returns the instance id of the object.
	ToString		Returns the name of the object.

Static Methods 静态方法

	Destroy		Removes a GameObject, component or asset.
	DestroyImmediate		Destroys the object obj immediately. You are strongly recommended to use Destroy instead.
	DontDestroyOnLoad		Do not destroy the target Object when loading a new Scene.
	FindObjectOfType		Returns the first active loaded object of Type type.
	FindObjectsOfType		Returns a list of all active loaded objects of Type type.
	Instantiate		Clones the object original and returns the clone.

Operators 运算符

	bool		Does the object exist?
	operator !=		Compares if two objects refer to a different object.
	operator ==		Compares two object references to see if they refer to the same object.
