Scratch Tidbits and Tips

About Face!

At our last meeting we had the question of whether we could set up our Sprites to face the direction of their movement automatically instead of having separate costumes for mirror images. It turns out that we can use the Rotation Style setting of each sprite to do that!

In this example, the characters will all start moving to the right and are programmed to make a 180 turn when touching the edge. How they look on their return trip to the left depends  on the Rotation Style setting.

Here they are after the 180; they are all moving to the left although one looks to be upside down and another moves “backward”:


Design Time vs Run Time Property Settings: Setting the Rotation Style in the IDE (Integrated Development Environment) as above is an example of a Design Time Property Setting. We can also change the Rotation Style during the program execution, i.e. Run Time,  by using the Set Rotation Style command in the Motion section of scripts.
