In Unity game engine and C# scripting; Is there any distinction between global space and world space? Are this two the same thing and identical or there is a distinction? I'm not confusing between local and global. The relation between local-global is the same to local-world? Can I exchange this two words (global and world) without creating confusion?

for example in the Unity manual: https://docs.unity3d.com/Manual/Transforms.html

Make a distinction adding "or":

world space or global coordinates.

    \$\begingroup\$ Global/world space are the same thing. The other space is local/mode-view \$\endgroup\$

  • \$\begingroup\$ Shoot meant to say model-view not mode... And yes by extension local has the same relation to world as it does to global as they are interchangeable \$\endgroup\$

  • \$\begingroup\$ In Unity making courses I here this distinction for this particular game engine. Here is the source video at 04:02 link: 3dmotive.com/series/advanced-c-in-unity-5/291/2635. \$\endgroup\$ Commented Mar 23, 2017 at 19:15

    \$\begingroup\$ There's nothing here that is Unity specific. The terms are generic 3D terms. I think this question is better as one that doesn't bother with "Unity" in the text or title, but I'm not going to get into a rollbar war with you over it. If you want to leave it this way, that's fine. There's no reason to make two questions though. \$\endgroup\$

1 Answer 1


I think it is basically the difference between relative and absolute positions.


So that a child gameObject's position/rotation/scale can be relative to it's parent (0, 0 is bottom left of window not screen) instead of


Which is absolute. (0, 0 is middle or bottom left of screen depending on anchors)

there is a toggle for this Local/Global setting in the toolbar too


enter image description here

Click the Local/Global button on the right to toggle between Local and Global.

  • Local keeps the Gizmo’s rotation relative to the GameObject’s.
  • Global clamps the Gizmo to world space orientation.
  • \$\begingroup\$ So the gismo unity Vector3 "rotation" that is in the inspector not accessible via coding are relative global values activated via this button and the C# functions as for example InverseTransformPoint are world absolute value. \$\endgroup\$ Commented Mar 23, 2017 at 23:01
  • \$\begingroup\$ ya the button is only for editing in editor with mouse or inspector... from source code use transform.localPosition for local (usually always) and transform.position for global \$\endgroup\$
