roboball2d.rendering.pyglet_renderer module

class roboball2d.rendering.pyglet_renderer.PygletRenderer(rendering_config, robot_configs, ball_configs, callbacks=[])

Bases: object

Renders world state instances, as returned for example by roboball2d.physics.b2_world.B2World.step(). See: roboball2d.physics.world_state.WorldState.

rendering_config:

instance of roboball2d.rendering.rendering_config.RenderingConfig

robot_configs :

list of robot configurations, see roboball2d.robot.default_robot_config.DefaultRobotConfig If only one robot is managed, a configuration instance may be passed.

ball_configs:

list of ball configurations, see roboball2d.ball.ball_config.BallConfig If only one ball is managed, a configuration instance may be passed.

callbacks:

list of callback functions, which should take a world state as argument roboball2d.physics.world_state.WorldState and use pyglet API for supplementary rendering. See: robotball2d.demos.rendering_callback().

__init__(rendering_config, robot_configs, ball_configs, callbacks=[])

rendering_config:

instance of roboball2d.rendering.rendering_config.RenderingConfig

robot_configs :

list of robot configurations, see roboball2d.robot.default_robot_config.DefaultRobotConfig If only one robot is managed, a configuration instance may be passed.

ball_configs:

list of ball configurations, see roboball2d.ball.ball_config.BallConfig If only one ball is managed, a configuration instance may be passed.

ball_configs

mode

render(world_state, goals=[], time_step=None, wait=True)

” Renders the world state. Spawn a window if called for the first time.

world_state:

state of the world as an instance of roboball2d.physics.world_state.WorldState

goals:

list of tuple (x1, x2, (r,g,b)). For each item, a goal will be drawn on the ground, using the specified color

time_step:

allows to force a frame rate by either; - having rendering waiting a suitable amount of time (wait=True) or - skipping some frames (wait=False)

wait:

see time_step above

roboball2d.rendering.rendering_config module

class roboball2d.rendering.rendering_config.RenderingConfig(visible_area_width, visual_height)

Bases: object

Provides rendering configuration. User code may change values of the attribute after instantiation.

visible_area_width: float

how much width (in meters) will be displayed

visual_height: float

how much height (in meters) will be displayed

background_color:

(R,G,B) (values between 0 and 1)

ground_color:

(R,G,B) (values between 0 and 1)

window :

instance with 2 attributes: width and height (in pixels)

location:

(x,y) desired location of the window, in pixels. (note that renderers may or may not be able to impose it)

__init__(visible_area_width, visual_height)

Initialize self. See help(type(self)) for accurate signature.
