Transform.Rotate

マニュアルに切り替える

説明

Use Transform.Rotate to rotate GameObjects in a variety of ways. The rotation is often provided as a Euler angle and not a Quaternion.

You can specify a rotation in world axes or local axes.

World axis rotation uses the coordinate system of the `Scene`, so when you start rotate a GameObject, its x, y, and z axes are aligned with the x, y, and z world axes. So if you randomly rotate a cube in world space, its axes align with the world. When you select a cube in the Unity Editor’s `Scene` view, rotation `Gizmos` appear for the left/right, up/down and forward/back rotation axes. Moving these `Gizmos` rotates the cube around the axes. If you de-select and then re-select the cube, the axes restart in world alignment.

Local rotation uses the coordinate system of the GameObject itself. So, a newly created cube uses its x, y, and z axis set to zero rotation. Rotating the cube updates the rotation axes. If you de-select and the re-select the cube, the axes will be shown in the orientation they were before.

public void Rotate (Vector3 eulers, Space relativeTo= Space.Self);

パラメーター

 eulers The rotation to apply. relativeTo Determines whether to rotate the GameObject either locally to the GameObject or relative to the Scene in world space.

説明

Applies a rotation of eulerAngles.z degrees around the z-axis, eulerAngles.x degrees around the x-axis, and eulerAngles.y degrees around the y-axis (in that order).

Rotate takes a Vector3 argument as a euler angle. The second argument is the rotation axes, which can be set to local axis (Space.Self) or global axis (Space.World). The rotation is by the Euler amount.

public void Rotate (float xAngle, float yAngle, float zAngle, Space relativeTo= Space.Self);

パラメーター

 relativeTo Determines whether to rotate the GameObject either locally to the GameObject or relative to the `Scene` in world space. xAngle Degrees to rotate the GameObject around the X axis. yAngle Degrees to rotate the GameObject around the Y axis. zAngle Degrees to rotate the GameObject around the Z axis.

説明

Z 軸で zAngle 度回転、X 軸で xAngle 度回転、Y 軸で yAngle 度回転します (順番は説明した順)

Rotate can have the euler angle specified in 3 floats for x, y, and z.

The example shows two cubes: one cube uses Space.Self (the local space and axes of the GameObject) and the other uses Space.World (the space and axes in relation to the `Scene`). Both cubes have the same angle using 3 `Scene`s. When two or three of the `Scene`s are given values of approximately 0.25f, both cubes will rotate. The X Value`Scene`Z Value Inspector fields store the rotation values. The cubes rotate in different ways. To see the difference, add the script to your `Scene` and take a look at the `Scene` view as the `Game` is running. In the `Scene` view, make sure that `Local` is set by the `Gizmo Toggle`, and select the `Self` cube. The `Self` cube rotates with the x, y and z arrows continuing their direction through the cube faces. Now change the `Gizmo Toggle` to `Global` and select the `World` cube. The is aligned with the world x, y and z axes.

```using UnityEngine;// Transform.Rotate example
//
// Two cubes are created.  One (red) is rendered using Space.Self.  The
// other (green) uses Space.World.  The rotation is controlled using xAngle,
// yAngle and zAngle. Over time, the cubes rotate differently.public class ExampleScript : MonoBehaviour
{
public float xAngle, yAngle, zAngle;
public Material selfMat, worldMat;    private GameObject cube1, cube2;    void Awake()
{
cube1 = GameObject.CreatePrimitive(PrimitiveType.Cube);
cube1.transform.position = new Vector3(0.75f, 0.0f, 0.0f);
cube1.GetComponent<Renderer>().material = selfMat;
cube1.name = "Self";        cube2 = GameObject.CreatePrimitive(PrimitiveType.Cube);
cube2.transform.position = new Vector3(-0.75f, 0.0f, 0.0f);
cube2.GetComponent<Renderer>().material = worldMat;
cube2.name = "World";
}    void Update()
{
cube1.transform.Rotate(xAngle, yAngle, zAngle, Space.Self);
cube2.transform.Rotate(xAngle, yAngle, zAngle, Space.World);
}
}
```

public void Rotate (Vector3 axis, float angle, Space relativeTo= Space.Self);

パラメーター

 angle The degrees of rotation to apply. axis The axis to apply rotation to. relativeTo Determines whether to rotate the GameObject either locally to the GameObject or relative to the Scene in world space.

説明

Rotates the object around the given axis by the number of degrees defined by the given angle.

Rotate has an axis, angle and the local or global parameters. The rotation axis can be in any direction.
