+# SetRotation
+
+Set the world rotation of this transform.
+
+## Syntax
+
+```cpp
+void SetRotation(const Math::Quaternion& rotation);
+```
+
+## Parameters
+
+- `rotation` - The new world rotation as a `Math::Quaternion`.
+
+## Remarks
+
+Sets the world-space rotation of this transform. If this transform has a parent, the local rotation is computed by transforming the world rotation into parent space.
+
+## See Also
+
+- [GetRotation](get-rotation)
+- [GetLocalRotation](get-local-rotation)
+- [SetLocalRotation](set-local-rotation)
+
+## Examples
+
+```cpp
+void Example(TransformComponent* transform) {
+    Math::Quaternion rot = Math::Quaternion::FromEuler(0.0f, 180.0f, 0.0f);
+    transform->SetRotation(rot);
+}
+```
