Sprite for platformer games that supports animations. These can be automatically created by the Tiled Map Editor.

Parameters:

• path_or_texture – Path to the image file, or a Texture object.

• center_x – Initial x position of the sprite.

• center_y – Initial y position of the sprite.

• scale – Initial scale of the sprite.

update_animation(delta_time: float = 0.016666666666666666) → None

Logic for updating the animation.

Parameters:

delta_time (float) – Time since last update.

arcade.AnimatedWalkingSprite

class arcade.AnimatedWalkingSprite(scale: float = 1.0, center_x: float = 0.0, center_y: float = 0.0, **kwargs)

Deprecated Sprite for platformer games that supports walking animations. Make sure to call update_animation after loading the animations so the initial texture can be set. Or manually set it.

It is highly recommended you create your own version of this class rather than try to use this pre-packaged one.

For an example, see this section of the platformer tutorial: Step 12 - Add Character Animations, and Better Keyboard Control.

Parameters:

• scale – Initial scale of the sprite.

• center_x – Initial x position of the sprite.

• center_y – Initial y position of the sprite.

Parameters:

other (Sprite) – the other sprite to check against.

Returns:

True or False, whether or not they are overlapping.

Return type:

bool

property color: Color

Get or set the RGBA multiply color for the sprite.

When setting the color, it may be specified as any of the following:

• an RGBA tuple with each channel value between 0 and 255

• an instance of Color

• an RGB tuple, in which case the color will be treated as opaque

Example usage:

>>> print(sprite.color)
Color(255, 255, 255, 255)

>>> sprite.color = 255, 0, 0

>>> sprite.color = 255, 0, 0, 128

property depth: float

Get or set the depth of the sprite.

This is really the z coordinate of the sprite and can be used with OpenGL depth testing with opaque sprites.

on_update(delta_time: float = 0.016666666666666666) → None

Update the sprite. Similar to update, but also takes a delta-time. It can be called manually or by the SpriteList’s on_update method.

Parameters:

delta_time (float) – Time since last update.

property position: Tuple[float, float]

Get or set the center x and y position of the sprite.

Returns:

(center_x, center_y)

remove_from_sprite_lists() → None

Remove the sprite from all sprite lists.

rescale_relative_to_point(point: Tuple[float, float], factor: float) → None

Rescale the sprite and its distance from the passed point.

This function does two things:

1. Multiply both values in the sprite’s scale_xy value by factor.

2. Scale the distance between the sprite and point by factor.

If point equals the sprite’s position, the distance will be zero and the sprite will not move.

Parameters:

• point – The reference point for rescaling.

• factor – Multiplier for sprite scale & distance to point.

Returns:

rescale_xy_relative_to_point(point: Tuple[float, float], factors_xy: Iterable[float]) → None

Rescale the sprite and its distance from the passed point.

This method can scale by different amounts on each axis. To scale along only one axis, set the other axis to 1.0 in factors_xy.

Internally, this function does the following:

1. Multiply the x & y of the sprite’s scale_xy attribute by the corresponding part from factors_xy.

2. Scale the x & y of the difference between the sprite’s position and point by the corresponding component from factors_xy.

If point equals the sprite’s position, the distance will be zero and the sprite will not move.

Parameters:

• point – The reference point for rescaling.

• factors_xy – A 2-length iterable containing x and y multipliers for scale & distance to point.

Returns:

property right: float

The rightmost x coordinate in the hit box.

When setting this property the sprite is positioned relative to the rightmost x coordinate in the hit box.

property scale: float

Get or set the sprite’s x scale value or set both x & y scale to the same value.

Note

Negative values are supported. They will flip & mirror the sprite.

property scale_xy: Tuple[float, float]

Get or set the x & y scale of the sprite as a pair of values.

property texture: Texture

Get or set the visible texture for this sprite This property can be changed over time to animate a sprite.

Note that this doesn’t change the hit box of the sprite.

property top: float

The highest y coordinate in the hit box.

When setting this property the sprite is positioned relative to the highest y coordinate in the hit box.

update() → None

Generic update method. It can be called manually or by the SpriteList’s update method.

update_animation(delta_time: float = 0.016666666666666666) → None

Generic update animation method. Usually involves changing the active texture on the sprite.

This can be called manually or by the SpriteList’s update_animation method.

Parameters:

delta_time (float) – Time since last update.

update_spatial_hash() → None

Update the sprites location in the spatial hash if present.

property visible: bool

Get or set the visibility of this sprite. This is a shortcut for changing the alpha value of a sprite to 0 or 255:

# Make the sprite invisible
sprite.visible = False
# Change back to visible
sprite.visible = True
# Toggle visible
sprite.visible = not sprite.visible

Return type:

bool

property width: float

Get or set width or the sprite in pixels

arcade.SpriteCircle

class arcade.SpriteCircle(radius: int, color: Tuple[int, int, int, int], soft: bool = False, **kwargs)

A circle of the specified radius.

The texture is automatically generated instead of loaded from a file.

There may be a stutter the first time a combination of radius, color, and soft is used due to texture generation. All subsequent calls for the same combination will run faster because they will re-use the texture generated earlier.

For a gradient fill instead of a solid color, set soft to True. The circle will fade from an opaque center to transparent at the edges.

Parameters:

• radius (int) – Radius of the circle in pixels

• color (Color) – The Color of the sprite as an RGB or RGBA tuple

• soft (bool) – If True, the circle will fade from an opaque center to transparent edges.

arcade.SpriteSolidColor

class arcade.SpriteSolidColor(width: int, height: int, center_x: float = 0, center_y: float = 0, color: Tuple[int, int, int, int] = Color(r=255, g=255, b=255, a=255), angle: float = 0, **kwargs)

A rectangular sprite of the given width, height, and color.

The texture is automatically generated instead of loaded from a file. Internally only a single global texture is used for this sprite type, so concerns about memory usage non-existent regardless of size or number of sprite variations.

Parameters:

• width (int) – Width of the sprite in pixels

• height (int) – Height of the sprite in pixels

• center_x (float) – Initial x position of the sprite

• center_y (float) – Initial y position of the sprite

• color (ColorLike) – The color of the sprite as a Color, an RGBA tuple, or an RGB tuple.

• angle (float) – Initial angle of the sprite in degrees

arcade.PyMunk

class arcade.PyMunk

Object used to hold pymunk info for a sprite.

arcade.PymunkMixin

class arcade.PymunkMixin

pymunk_moved(physics_engine, dx, dy, d_angle)

Called by the pymunk physics engine if this sprite moves.

arcade.load_animated_gif

arcade.load_animated_gif(resource_name) → AnimatedTimeBasedSprite

Attempt to load an animated GIF as an AnimatedTimeBasedSprite.

Many older GIFs will load with incorrect transparency for every frame but the first. Until the Pillow library handles the quirks of the format better, loading animated GIFs will be pretty buggy. A good workaround is loading GIFs in another program and exporting them as PNGs, either as sprite sheets or a frame per file.

arcade.Sprite

class arcade.Sprite(path_or_texture: str | Path | Texture | None = None, scale: float = 1.0, center_x: float = 0.0, center_y: float = 0.0, angle: float = 0.0, **kwargs)

Sprites are used to render image data to the screen & perform collisions.

Most games center around sprites. They are most frequently used as follows:

1. Create Sprite instances from image data

2. Add the sprites to a SpriteList instance

3. Call SpriteList.draw() on the instance inside your on_draw method.

For runnable examples of how to do this, please see arcade’s built-in Sprite examples.
