draw_karel_df: Generate a dataset to plot Karel's figure in each time

In mpru/karel: Learning programming with Karel the robot

Generate a dataset to plot Karel's figure in each time

Description

Karel is drawn with 6 squares (body, feet, eyes and mouth) using geom_rect(), so we need arguments xmin, xmax, ymin and ymax for each of them. So this function takes Karel's current position (x, y) and direction (1 east, 2 north, 3 west, 4 south) and generates the corresponding values of xmin, xmax, ymin and ymax.

Usage

draw_karel_df(x, y, direction, moment)

Details

This function is called repeatedly for each position of Karel through time.

Value

A 6x7 tibble. First row is for the body, 2nd for the left foot, then right foot, left eye, right eye and finally the mouth. Columns are xmin, xmax, ymin, ymax, moment (time), a color (for fill) and a transparency value (alpha)
