In this add-on,
you'll program the ship to sink
and add events to make the ship sinking part of your story.
To start, program the boat to move down.
Click the boat sprite and the motion menu.
To smoothly move a sprite to a different position,
use a glide block.
This block has two values, an x and a y.
The x value shows the sprite's position
on the left or right sides of the stage.
And the y value shows its position
on the top or bottom of the stage.
Click and move the boat to a spot at the bottom of the sea.
Notice that the values in the glide block changed
to reflect the boat's position.
Drag out the glide block.
When you run this block,
the sprite will glide to the position
you just selected.
Click and drag the boat to a different spot.
Then click the block.
Great, the sprite glides to the spot
set by the x and y values in the block.
The ship is sinking.
Next, program a starting position for the ship.
Drag the boat until it's floating on the water
and place a go to x y block
under the when flag clicked block.
The values in the go to x y block also update
to the sprite's current position.
To test this, click the flag.
The boat starts on top of the water.
When you click the glide block, the ship sinks, awesome.
Next, tell the code when to run.
In this example,
the ship sinks after the save blocks run.
Click the last sprite to talk.
Select events and drag a broadcast block
to the end of the block stack.
Click the dropdown and create a new message
called sink the ship.
Next, select the boat sprite
and add a when I receive sink the ship event
above the glide block.
When the broadcast block runs at the end of the dialogue,
it will send the message telling this glide block to run.
Click the flag to try it out.
The dialogue runs.
Then the boat sinks, cool.
Next, program the sprites to sink with the boat.
Reuse the code from the sinking ship
for the two talking sprites.
Drag the when I receive block into each sprite.
This copies the code.
Click on each sprite to check that the code is there.
Next, set a starting position for each sprite.
To make the sprite start on top of the water,
drag a go to block after the when flag clicked
for each sprite.
Click the flag to try it all together.
Awesome, next build the sinking ship into your storyline.
In this example,
one sprite jumps up and down before the ship sinks
making it look like the sprite is responsible.
Now it's your turn.
Make the sprites sink using a glide block.
Program the sprites to start in the same position
each time with go to blocks,
broadcast a message to trigger the code
for sinking the ship,
and add a when I receive event to the glide block.
And finally, add events to make the sinking ship
part of your story.
