Scratch Unit 2 Questions

1. In scratch, there are loops to repeat an event z times, loops that will repeat forever, and loops that will repeat until an event triggers them, such as touching an edge, or hitting a key.

2. Repeat forever is the best option if no definite stop is in mind. This way, the script will run until you end it.

3. The loop structure won't work because it will say forever and ever indefinitley, and will never have a chance to proceed to the second half of the loop.

4. Sprites will know when to begin an action through the use of logic. This includes scripts such as when a message is broadcasted, or if a sprite hits an edge.

5. Yes, they are the same. The second is just a double negative of the first.
