Introduction to Computer Science with Scratch and App Inventor

Now I can modify my script so that my dinosaur always faces the same direction he is moving. I will do
this using the switch to costume block from the looks menu. The looks menu (purple blocks) contains
actions that let us control how the appearance of our sprite changes during a program.
Changing Your Sprite’s Looks
To change the costume of our sprite, we used a block from the looks menu. The looks menu contains
blocks that change things like the color and size of your sprite.
Try out different looks blocks and see
what happens. This simple example
shows a change color effect block. Now
the dinosaur will cycle through color
changes every second.
Now, when the right arrow is pressed, our sprite
will face to the right and move to the right
When the left arrow is pressed, the sprite will face
to the left and move to the left.
The looks blocks are the dark purple blocks.
