Spel46: Micky Mouse Marathon

 

Vi programmerar ett spel som går ut på att med en viss given energimängd genomföra ett maratonlopp över kuperad terräng så snabbt som möjligt. Displayen visar hastighet, momentan energiförbrukning, total energiförbrukning och att man kan styra hastigheten genom framåt och bakåt knappar. Om den tillgängliga energimängden är förbrukad innan målgång kollapsar man och får bryta. Titta på ett sådant fall här. Man kan här få hands-on erfarenhet av begrepp som hastighet, kraft, arbete, energi och effekt = energi/tidsenhet.
