Level: Intermediate

What you get:

  1. 8 PNG images of a blue beetle at different angles.

  2. “BEETLES”: a stack leveraging the ARROW Keys on the keyboard to exchange images inside a graphic frame. [ the code for this is in the cardScript ]

  3. “BEETLES 8”: a stack using the 1,2,3,4,6,7,8 & 9 keys of the number pad on the keyboard to exchange images
    inside a graphic frame. [ the code for this is in the cardScript ] This stack uses rawKeyDown / rawKeyUp

  4. “BEETLES move”: a stack leveraging the ARROW Keys on the keyboard to exchange images inside a graphic frame, and move it. [ the code for this is in the cardScript ]

Ideally pupils should be given the first stack (“BEETLES”) with the code for the “right”, “left” and “down” keys removed so that they can complete that.

Then pupils should be given “BEETLES 8” with all but the code for number pad keys 8 and 9 removed.

Then the pupils can play around with “BEETLES move” and use what they learn from that to animate the graphic in “BEETLES 8”.

An active bunch of kids should get through this lot in about 90 minutes: my starters did in their 9th class.
