Submodules

Window Commands Module

This submodule has functions that control opening, closing, rendering, and otherwise managing windows. It also has commands for scheduling pauses and scheduling interval functions.

arcade.window_commands.close_window()

Closes the current window, and then runs garbage collection. The garbage collection is necessary to prevent crashing when opening/closing windows rapidly (usually during unit tests).

Param:None Returns:None Raises:None

arcade.window_commands.finish_render()

Swap buffers and displays what has been drawn. If programs use derive from the Window class, this function is automatically called.

Example:

>>> import arcade
>>> arcade.open_window("Drawing Example", 800, 600)
>>> arcade.set_background_color(arcade.color.RED)
>>> arcade.start_render()
>>> # All the drawing commands go here
>>> arcade.finish_render()
>>> arcade.quick_run(0.25)

arcade.window_commands.get_window() → typing.Union[pyglet.window.xlib.XlibWindow, NoneType]

Return a handle to the current window.

Param:None Return window:Handle to the current window. Raises:None

arcade.window_commands.open_window(window_title: str, width: numbers.Number, height: numbers.Number)

This function opens a window. For ease-of-use we assume there will only be one window, and the programmer does not need to keep a handle to the window. This isn’t the best architecture, because the window handle is stored in a global, but it makes things easier for programmers if they don’t have to track a window pointer.

Args:

window_title:Title of the window. width:Width of the window. height:Height of the window.

Returns:

None

Raises:

None

Example:

>>> import arcade
>>> arcade.open_window("Drawing Example", 800, 600)
>>> arcade.quick_run(0.25)

arcade.window_commands.pause(seconds: numbers.Number)

Pause for the specified number of seconds. This is a convenience function that just calls time.sleep()

Parameters:seconds (float) – Time interval to pause in seconds. Returns:None Raises:None

>>> import arcade
>>> arcade.pause(0.25) # Pause 1/2 second

arcade.window_commands.quick_run(time_to_pause: numbers.Number)

Only run the application for the specified time in seconds. Useful for unit testing or continuous integration (CI) testing where there is no user interaction.

Args:

time_to_pause:Number of seconds to pause before automatically closing.

Returns:

None

Raises:

None

Example:

arcade.window_commands.run()

Run the main loop. After the window has been set up, and the event hooks are in place, this is usually one of the last commands on the main program.

arcade.window_commands.schedule(function_pointer: typing.Callable, interval: numbers.Number)

Schedule a function to be automatically called every interval seconds.

Args:

function_pointer:  Pointer to the function to be called. interval:Interval to call the function.

Returns:

None

Raises:

None

arcade.window_commands.set_background_color(color: typing.List[int])

This specifies the background color of the window.

Args:

color (tuple):List of 3 or 4 bytes in RGB/RGBA format.

Returns:

None

Raises:

None

Example:

>>> import arcade
>>> arcade.open_window("Drawing Example", 800, 600)
>>> arcade.set_background_color(arcade.color.RED)
>>> arcade.start_render()
>>> arcade.finish_render()
>>> arcade.quick_run(0.25)

arcade.window_commands.set_viewport(left: numbers.Number, right: numbers.Number, bottom: numbers.Number, top: numbers.Number)

This sets what coordinates the window will cover.

By default, the lower left coordinate will be (0, 0) and the top y coordinate will be the height of the window in pixels, and the right x coordinate will be the width of the window in pixels.

If a program is making a game where the user scrolls around a larger world, this command can help out.

Note: It is recommended to only set the view port to integer values that line up with the pixels on the screen. Otherwise if making a tiled game the blocks may not line up well, creating rectangle artifacts.

Args:

left:Left-most (smallest) x value. right:Right-most (largest) x value. bottom:Bottom (smallest) y value. top:Top (largest) y value.

Returns:

None

Raises:

None

Example:

>>> import arcade
>>> arcade.open_window("Drawing Example", 800, 600)
>>> set_viewport(-1, 1, -1, 1)
>>> arcade.quick_run(0.25)

arcade.window_commands.set_window(window: pyglet.window.xlib.XlibWindow)

Set a handle to the current window.

Args:

window:Handle to the current window.

Returns:

None

Raises:

None

arcade.window_commands.start_render()

Get set up to render. Required to be called before drawing anything to the screen.

Draw Commands Module

This module contains commands for basic graphics drawing commands. (Drawing primitives.)

class arcade.draw_commands.Texture(texture_id: int, width: float, height: float)

Bases: object

Class that represents a texture. Usually created by the load_texture or load_textures commands.

Attributes:

id:ID of the texture as assigned by OpenGL width:Width of the texture image in pixels height:Height of the texture image in pixels

class arcade.draw_commands.VertexBuffer(vbo_id: ctypes.c_uint, size: float, width: float, height: float, color: typing.Union[typing.Tuple[int, int, int], typing.List[int], typing.Tuple[int, int, int, int]])

Bases: object

This class represents a vertex buffer object.

Attributes:

vbo_id:ID of the vertex buffer as assigned by OpenGL size: width: height: color:

>>> import arcade
>>> x = VertexBuffer(0, 10, 10, 10, arcade.color.AERO_BLUE)

arcade.draw_commands.create_ellipse(width: float, height: float, color: typing.Union[typing.Tuple[int, int, int], typing.List[int], typing.Tuple[int, int, int, int]]) → arcade.draw_commands.VertexBuffer

This creates an ellipse vertex buffer object (VBO). It can later be drawn with render_ellipse_filled. This method of drawing an ellipse is much faster than calling draw_ellipse_filled each frame.

Note: THis can’t be unit tested on Appveyor because its support for OpenGL is poor.

import arcade arcade.open_window(“Drawing Example”, 800, 600) arcade.set_background_color(arcade.color.WHITE) arcade.start_render() ellipse_a = arcade.create_ellipse(100, 100, arcade.color.RED) ellipse_b = arcade.create_ellipse(100, 100, (0, 255, 0, 127)) render_ellipse_filled(ellipse_a, 200, 200, 45) render_ellipse_filled(ellipse_b, 250, 250, 45) arcade.finish_render() arcade.quick_run(0.25)

arcade.draw_commands.create_rectangle(width: float, height: float, color: typing.Union[typing.Tuple[int, int, int], typing.List[int], typing.Tuple[int, int, int, int]]) → arcade.draw_commands.VertexBuffer

This function creates a rectangle using a vertex buffer object. Creating the rectangle, and then later drawing it with render_rectangle is faster than calling draw_rectangle.

arcade.draw_commands.draw_arc_filled(center_x: float, center_y: float, width: float, height: float, color: typing.Union[typing.Tuple[int, int, int], typing.List[int], typing.Tuple[int, int, int, int]], start_angle: float, end_angle: float, tilt_angle: float = 0)

>>> arcade.quick_run(0.25)

set_points(points: typing.Sequence[typing.Sequence[float]])

set_position(center_x: float, center_y: float)

Set a sprite’s position

set_texture(texture_no: int)

Assuming ‘texture’ is a list of textures, this sets which texture index should be displayed. It also resets the width and height based on the scale of the texture.

texture

Return the texture that the sprite uses.

top

Return the y coordinate of the top of the sprite.

>>> import arcade
>>> arcade.open_window("Sprite Example", 800, 600)
>>> scale = 1.0
>>> ship_sprite = arcade.Sprite("examples/images/playerShip1_orange.png", scale)
>>> ship_sprite.center_y = 0.0
>>> print(ship_sprite.top)
37.5
>>> ship_sprite.top = 1.0
>>> print(ship_sprite.top)
1.0
>>> arcade.quick_run(0.25)

update()

Update the sprite.

update_animation()

Override this to add code that will change what image is shown, so the sprite can be animated.

class arcade.sprite.SpriteList

Bases: object

List of sprites.

Unit Test:

>>> import arcade
>>> import random
>>> arcade.open_window("Sprite Example", 600, 600)
>>> scale = 1
>>> meteor_list = arcade.SpriteList()
>>> filename = "examples/images/meteorGrey_big1.png"
>>> for i in range(100):
...     meteor = arcade.Sprite(filename, scale)
...     meteor.center_x = random.random() * 2 - 1
...     meteor.center_y = random.random() * 2 - 1
...     meteor_list.append(meteor)
>>> meteor_list.remove(meteor) # Remove last meteor, just to test
>>> m = meteor_list.pop() # Remove another meteor, just to test
>>> meteor_list.update() # Call update on all items
>>> print(len(meteor_list))
98
>>> arcade.set_background_color(arcade.color.WHITE)
>>> arcade.start_render()
>>> meteor_list.draw(fast=False)
>>> arcade.finish_render()
>>> for meteor in meteor_list:
...     meteor.kill()
>>> arcade.quick_run(0.25)

append(item: arcade.sprite.Sprite)

Add a new sprite to the list.

draw(fast: bool = True)

Call the draw() method on each sprite in the list.

pop() → arcade.sprite.Sprite

Pop off the last sprite in the list.

remove(item: arcade.sprite.Sprite)

Remove a specific sprite from the list.

update()

Call the update() method on each sprite in the list.

update_animation()

Call the update_animation() method on each sprite in the list.

Physics Engines Module

Physics engines for top-down or platformers.

class arcade.physics_engines.PhysicsEnginePlatformer(player_sprite: arcade.sprite.Sprite, platforms: arcade.sprite.SpriteList, gravity_constant: float = 0.5)

Bases: object

This class will move everything, and take care of collisions.

can_jump() → bool

Method that looks to see if there is a floor under the player_sprite. If there is a floor, the player can jump and we return a True.

update()

Move everything and resolve collisions.

class arcade.physics_engines.PhysicsEngineSimple(player_sprite: arcade.sprite.Sprite, walls: arcade.sprite.SpriteList)

Bases: object

This class will move everything, and take care of collisions.

update()

Move everything and resolve collisions.

Sound Module

Small abstraction around the sound library.

arcade.sound.load_sound(filename: str) → typing.Any

Load a sound and get it ready to play.

arcade.sound.load_sound_library()

Special code for Windows so we grab the proper avbin from our directory. Otherwise hope the correct package is installed.

arcade.sound.play_sound(sound: typing.Any)

Play a previously loaded sound.
