What is ‘animation’? How does animation work? Watch video clip from lesson 6

Learning Intention: sequencing instructions to make simple animations in Python Can you translate how we animate into an algorithm for Python? Set position of shape Draw Shape Delete shape Repeat

Learning Intention: sequencing instructions to make simple animations in Python Choose your task based on your confidence! Hard Complete the tutorial sections to animate a simple shape. Complete all but the ‘mega- challenges’ sections for an outstanding work award. Harder Work through the tutorials at a snappy pace, completing the mega challenges! Hardest Explore the random element to add a more natural look to your own animations. Mega-challenge ****really hard****: Can you use ‘Def’ to create a function to draw shapes before the while loop, and then use the procedure to draw the shape?

Learning Intention: sequencing instructions to make simple animations in Python Your screen pygame.draw.rect(screen, WHITE, [rect_x, 50, 50, 50])

Learning Intention: sequencing instructions to make simple animations in Python rect_x += 1 What does this line of code do? What does changing the 1 do?
