Timing

This Haskell tiny game implements a timing game. How well can you estimate a duration of time?

• Category: base-10-80
• Tested environment: Stack lts-20.10 (GHC 9.2.5) on Linux
• Author: TravisCardwell

How to Play

Download the source files:

$ git clone https://github.com/haskell-game/tiny-games-hs.git
$ cd base/timing

With Stack installed, execute the game:

$ ./timing.hs

Alternatively, you can execute the game using runghc:

$ runghc timing.hs

The default duration is 30 seconds. You may specify a different duration using a command-line argument, as follows:

$ ./timing.hs 5

After the game builds, instructions are displayed.

Press enter.  Wait 30 seconds.  Press enter.

Press enter, wait for the specified duration, and then press enter again. The idea is to test how well you can estimate a duration of time, so do not use an external time reference such as a clock. The game displays how long you waited and your score, from 0 (terrible) to 100 (excellent):

You waited 31.64782962400932 seconds.
Score: 94.5072345866356

Notes

• There is no error handling. The program exits with an error if the input is not correct, for example.
• There is no input validation. It is up to the player to input a valid argument.
• A comment on line 1 breaks some parsers, so I used a Haskell comment on line 4 instead.
