AngryMathBirds Medium

 

Här är en Angry Birds demo som visar hur man med touch() can bestämma riktning och hastighet av något som kastas mot otäcka skalbaggar som ramlar ner från himlen för att pricka ner dom. Titta AngryMathBirds Demo 1 hur spelet funkar (med lite andra bilder hämtade från Assets)
