Golf me a polygonal loader

+2
−0

CGCC Sandbox, Codidact Sandbox

Given three positive integers as input, animate an ascii-art polygonal loading symbol on the screen.

Intro

Using the first input $n$, Take one the following regular polygons:

                           * * *
                          *     *
                * * *    *       *
               *     *   *       *
  *    * * *  *       *  *       *
 * *   *   *   *     *    *     *
* * *  * * *    * * *      * * *

And draw it with the correct side length $l$.

Given load length $d$ lesser than it's perimeter, create it's loading animation as follows:

  • Start at any one of the topmost corners, and draw the bounding line till it's length is $d$.
  • Then, shift the position by 1 clockwise and do the next step.

For example, $n=3,l=3,d=4$ would result in the following steps:

  *                        *       *       *
   *  →    *  →   *    →  *    →  * *  →  * *  → . . .
  * *   * * *    * * *   * *     *           *

Further details(important):

  • You are guaranteed that $n∊(3,4,6,8)$
  • You are guaranteed that $l≥3.$
  • You are guaranteed that $d<l×n.$
  • There must be a delay of at least 0.1 s between each step. You can have a delay of up to 10 seconds.
  • Your language is allowed to output a list of steps infinitely if and only if it cannot clear the screen or do something similar.
  • If so, there must be at least 2 newlines between each step.
  • This is not graphical-output.

Scoring

This is code-golf. Shortest answer in each language wins.
