+# SetLocalScale
+
+Set the scale of this transform relative to the parent transform.
+
+## Syntax
+
+```cpp
+void SetLocalScale(const Math::Vector3& scale);
+```
+
+## Parameters
+
+- `scale` - The new local scale as a `Math::Vector3`.
+
+## Remarks
+
+Sets the local scale of this transform. If this transform has no parent, local scale is the same as world scale. This marks the transform as dirty.
+

+
+## Examples
+
+```cpp
+void Example(TransformComponent* transform) {
+    transform->SetLocalScale(Math::Vector3(2.0f, 2.0f, 2.0f));
+}
+```
