Building a tron game always moving leaves a trail of where it"s been int previousx = 0; int previousy = 0; act() addobject(previousx,previousy) previousx = getx(); previousy = gety(); getworld(). addobject(getx(),gety(),dot()); move(1); if (iskeydown( left )) { turn(-90); if (iskeydown( right )) { turn(90); For the most part, no questions will be taken from past quizzes. Always loop inside a loop: will be asked to ll a pattern of lowers in a 12x12 block world.
