color (ray.Color): The color to tint the texture.
frame (int): The frame of the texture to draw. Only used if the texture is animated.
scale (float): The scale factor to apply to the texture.
center (bool): Whether to center the texture.
mirror (str): The direction to mirror the texture, either 'horizontal' or 'vertical'.
x (float): An x-value added to the top-left corner of the texture.
y (float): The y-value added to the top-left corner of the texture.
x2 (float): The x-value added to the bottom-right corner of the texture.
y2 (float): The y-value added to the bottom-right corner of the texture.
origin (ray.Vector2): The origin point of the texture.
rotation (float): The rotation angle of the texture.
fade (float): The fade factor to apply to the texture.
index (int): The index of the position data for the texture. Only used if the texture has multiple positions.
src (Optional[ray.Rectangle]): The source rectangle of the texture.
controllable (bool): Whether the texture is controllable.
