Unity 3D: Set the Height and Width of a Game Object in Unity Using C#

The following will set the height and/or width of a GameObjects RectTransform.

copy
public static void Set_Size(Component component, float width, float height)
{
	if (component != null)
	{
		Set_Size(component.gameObject, width, height);
	}
}
public static void Set_Size(GameObject gameObject, float width, float height)
{
	if (gameObject != null)
	{
		var rectTransform = gameObject.GetComponent<RectTransform>();
		if (rectTransform != null)
		{
			rectTransform.sizeDelta = new Vector2(width, height);
		}				
	}
}


public static void Set_Height(Component component, float height)
{
	if (component != null)
	{
		Set_Height(component.gameObject, height);
	}
}
public static void Set_Height(GameObject gameObject, float height)
{
	if (gameObject != null)
	{
		var rectTransform = gameObject.GetComponent<RectTransform>();
		if (rectTransform != null)
		{
			rectTransform.sizeDelta = new Vector2(rectTransform.sizeDelta.x, height);
		}
	}
}


public static void Set_Width(Component component, float width)
{
	if (component != null)
	{
		Set_Width(component.gameObject, width);
	}
}
public static void Set_Width(GameObject gameObject, float width)
{
	if (gameObject != null)
	{
		var rectTransform = gameObject.GetComponent<RectTransform>();
		if (rectTransform != null)
		{
			rectTransform.sizeDelta = new Vector2(width, rectTransform.sizeDelta.y);
		}
	}
}
