# Space
> The coordinate spaces in which to apply transformation to a GameObject.
## Definition
* **Type:** Enum
* **Namespace:** [UnityEngine](/engine/6000.0/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule
```csharp
public enum Space
```
## Remarks
You can pass a value from this enum as a parameter to methods such as [Transform.Rotate](/engine/6000.0/script-reference/unityengine/transform/rotate.md) and [Transform.Translate](/engine/6000.0/script-reference/unityengine/transform/translate.md) to specify which coordinate space the transformation is applied in.
World coordinate space represented by [Space.World](/engine/6000.0/script-reference/unityengine/space/world.md) refers to the position of a GameObject relative to the origin point (0,0,0) of the x-, y-, and z-axes of the scene. The [Transform.position](/engine/6000.0/script-reference/unityengine/transform/position.md) property gives a GameObject's current position in world space.
Use [Space.World](/engine/6000.0/script-reference/unityengine/space/world.md) to transform a GameObject relative to its [Transform.position](/engine/6000.0/script-reference/unityengine/transform/position.md) and the scene axes, ignoring the GameObject's own orientation. For example, `transform.Translate(Vector3.forward, Space.World)` adds one unit to the object's [Transform.position](/engine/6000.0/script-reference/unityengine/transform/position.md) on the z-axis of the scene.
Local coordinate space represented by [Space.Self](/engine/6000.0/script-reference/unityengine/space/self.md) refers to the position of an object relative to its parent GameObject, including any rotation of the parent GameObject. The [Transform.localPosition](/engine/6000.0/script-reference/unityengine/transform/localposition.md) property gives a GameObject's current position in local space, which is relative to the parent GameObject if there is one. If a GameObject has no parent, its [Transform.localPosition](/engine/6000.0/script-reference/unityengine/transform/localposition.md) is the same as its [Transform.position](/engine/6000.0/script-reference/unityengine/transform/position.md).
For example, a GameObject with no parent and a [Transform.position](/engine/6000.0/script-reference/unityengine/transform/position.md) of (1,3,0) will also have a [Transform.localPosition](/engine/6000.0/script-reference/unityengine/transform/localposition.md) of (1,3,0). But if a child GameObject to this first object has [Transform.position](/engine/6000.0/script-reference/unityengine/transform/position.md) (1,3,0), the child object's [Transform.localPosition](/engine/6000.0/script-reference/unityengine/transform/localposition.md) is (0,0,0) because it's in the same position as the parent object.
Use [Space.Self](/engine/6000.0/script-reference/unityengine/space/self.md) to transform a GameObject relative to its [Transform.localPosition](/engine/6000.0/script-reference/unityengine/transform/localposition.md) and its own local axes, taking its orientation into account. For example, `Transform.Translate(Vector3.forward, Space.Self)` adds one unit to the object's [Transform.localPosition](/engine/6000.0/script-reference/unityengine/transform/localposition.md) on the z-axis of the object, which may differ from the z-axis of the scene depending on the object's orientation. Select an object in the Scene view to see its local position and axes.

```csharp
// Attach this script to a GameObject.
// This example demonstrates the difference between Space.World and Space.Self in rotation.
// The inWorldSpace field is automatically exposed as a checkbox in the Inspector window labelled In World Space. Enable or disable the checkbox in the Inspector to start in world or self space, respectively.
// Press play to see the GameObject rotating appropriately. Press space or toggle the In World Space checkbox to switch between world and self space.
using UnityEngine;
public class Example : MonoBehaviour
{
float rotationSpeed;
public bool inWorldSpace;
void Start()
{
// Set the speed of the rotation
rotationSpeed = 20.0f;
// Start off in World.Space
inWorldSpace = true;
// Rotate the GameObject a little at the start to show the difference between world and local spaces
transform.Rotate(60, 0, 60);
}
void Update()
{
// Rotate the GameObject in world space if inWorldSpace is true
if (inWorldSpace)
transform.Rotate(Vector3.up * rotationSpeed * Time.deltaTime, Space.World);
// Otherwise, rotate the GameObject in local space
else
transform.Rotate(Vector3.up * rotationSpeed * Time.deltaTime, Space.Self);
// Press the Space button to switch between world and local space states
if (Input.GetKeyDown(KeyCode.Space))
{
// Make the current state switch to the other state
inWorldSpace = !inWorldSpace;
// Output the current state to the console
Debug.Log("World space : " + inWorldSpace.ToString());
}
}
