The ToLocal method of the Transform struct is used to convert a given child transform from world space to local space relative to the current transform. This is useful when you need to understand the position, rotation, and scale of a child object in relation to its parent object.
To use the ToLocal method, you need to have a Transform instance representing the parent and another Transform instance representing the child. Call the method on the parent transform, passing the child transform as a parameter. The method will return a new Transform that represents the child in the local space of the parent.
// Example usage of Transform.ToLocal
Transform parentTransform = new Transform
{
Position = new Vector3(10, 0, 0),
Rotation = Rotation.FromAxis(Vector3.Up, 45),
Scale = new Vector3(1, 1, 1)
};
Transform childTransform = new Transform
{
Position = new Vector3(15, 5, 0),
Rotation = Rotation.FromAxis(Vector3.Up, 90),
Scale = new Vector3(1, 1, 1)
};
// Convert child transform to local space relative to the parent
Transform localTransform = parentTransform.ToLocal(childTransform);
// localTransform now contains the position, rotation, and scale of the child relative to the parent.
