1.2 The block palette and scripts area
To program a sprite, you drag blocks from the Blocks Palette to the Scripts Area. To run a block, click on it. Create scripts (programs) by connecting blocks together into stacks.
Connecting Blocks
When you drag a block around the Scripts Area, a white/grey area highlight indicates where you can drop the block and form a valid connection with another block.

To move a stack, pick it up from the top block. If you drag out a block from the middle of a stack, all the blocks beneath it will come along with it.
To copy a stack of blocks from one sprite to another, drag the stack to the thumbnail of the other sprite in the Sprite List.

Blocks with Editable Text Files
Some blocks have a white field in which you can edit values.
To change the value, click inside the white area, delete the existing number, and type a new number.
You can also drop rounded blocks inside these areas as shown below:

Blocks with Drop Down Menu
Some blocks have pull-down menus. Just click on them to see the contents, and then click on the value you want to select.
