+Set the world position of this transform.
+
+## Syntax
+
+```cpp
+void SetPosition(const Math::Vector3& position);
+```
+
+## Parameters
+
+- `position` - The new world position as a `Math::Vector3`.
+
+## Remarks
+
+Sets the world-space position of this transform. If this transform has a parent, the local position is computed by transforming the world position into parent space.

+}
