class arcade.texture.transforms.Transform

Bases:

Base class for all texture transforms.

Transforms are responsible for transforming the texture coordinates and hit box points.

static transform_hit_box_points(points: Sequence[Tuple[float | int, float | int]]) → Sequence[Tuple[float | int, float | int]]

Transforms hit box points.

classmethod transform_texture_coordinates_order(texture_coordinates: Tuple[float, float, float, float, float, float, float, float], order: Tuple[int, int, int, int]) → Tuple[float, float, float, float, float, float, float, float]

Change texture coordinates order.

Parameters:

• texture_coordinates – Texture coordinates to transform

• order – The new order

classmethod transform_vertex_order(order: Tuple[int, int, int, int]) → Tuple[int, int, int, int]

Transforms and exiting vertex order with this transform. This gives us important metadata on how to quickly transform the texture coordinates without iterating all applied transforms.

order = (0, 1, 2, 3)

How texture coordinates order should be changed for this transform. upper_left, upper_right, lower_left, lower_right

class arcade.texture.transforms.TransposeTransform

Bases: Transform

Transpose texture.

order = (0, 2, 1, 3)

How texture coordinates order should be changed for this transform. upper_left, upper_right, lower_left, lower_right

class arcade.texture.transforms.TransverseTransform

Bases: Transform

Transverse texture.

order = (3, 1, 2, 0)

How texture coordinates order should be changed for this transform. upper_left, upper_right, lower_left, lower_right

class arcade.texture.transforms.VertexOrder(value)

Bases: Enum

Order for texture coordinates.

UPPER_LEFT = 0

UPPER_RIGHT = 1

arcade.texture.transforms.get_orientation(order: Tuple[int, int, int, int]) → int

Get orientation info from the vertex order
