Today's starter project has
a gray architect's toolbox at the top.
In this box are building piece sprites that the user
of your software can use to create a building.
To allow someone to select a building piece sprite from
the toolbox, you'll need to program them so that one: when a
sprite is clicked it creates a copy or clone of itself.
Two: the clone follows the mouse pointer
until the mouse is clicked again.
And three: the clone stamps on the stage.
The next few videos will walk you through
how to program the arch sprite.
You will program the rest of the sprites on your own.
First, create a clone, this clone
will become what you stamp, so
the building piece sprite can stay in your toolbox.
A clone is a copy of the sprite.
The clone looks just like the original sprite
and does whatever the sprite does.
From the control menu, drag out the create clone of block.
Click on the create clone of block to test what it does.
It looks like nothing happens.
If you click and drag the sprite away from
the toolbox however, then you'll see
that there's a copy underneath it.
For today's project, clones should appear
when the user clicks on the original sprite.
Go to the events menu, drag out the
'when this sprite is clicked' block, and place it
above the 'create clone of myself' block.
To test, click the sprite to make a clone,
then click and drag the sprite to move it aside.
You should see the clone beneath the original sprite.
Click on the stop sign to remove all the clones.
Then, drag the building block sprite
into its spot in the toolbox.
Now it's your turn.
Make a clone of the sprite in the toolbox with the
'create clone of' and 'when this sprite is clicked' blocks.
