Press the green flag to start, then click on character sprites (:
After creating the sprites, I was initially unsure how to have the U.S. respond. I thought initially that I would have the U.S. sprite respond when any character sprite moved (to a set coordinate location within the U.S.), though this wasn't *really* meeting the challenge, just a simulation of what that kind of response might look like. A quick trip to the sensing blocks and I found the 'touching (dropdown)' block, which seemed it would come in handy. A trip back to the control blocks and I found the 'wait until' block. By combining these blocks, If I signaled to start by pressing the green button, the response became no longer simulated -- if someone moves the character sprites arbitrarily, the U.S. sprite will respond to touching a character sprite. Perhaps I should have the character sprites speak if they're touching the U.S. sprite. I think I'd also like to add some more scenarios and potential conversations.
