+# LookAt
+
+Rotate the transform to face a target position.
+
+## Syntax
+
+```cpp
+void LookAt(const Math::Vector3& target);
+void LookAt(const Math::Vector3& target, const Math::Vector3& up);
+```
+
+## Parameters
+
+- `target` - The position to look at.
+- `up` - The up vector to use (defaults to world up).
+
+## Remarks
+
+Rotates the transform so its forward direction points toward the target position. The optional `up` vector defines which direction is considered up.
+
+## Examples
+
+```cpp
+void Example(TransformComponent* transform) {
+    Math::Vector3 targetPos(10.0f, 0.0f, 5.0f);
+    transform->LookAt(targetPos);
+}
+```
