What Animal Am I?

Introduction @fullscreen

Create different animal effects with your @boardname@.

Step 1

Open the ||brick:Brick|| Toolbox drawer. Drag out a ||brick:show string|| block from the Screen section onto the Workspace, and drop it into the ||loops:on start|| block. You should hear and see the block click into place.

brick.showString("Hello world", 1)

Step 2

In the ||brick:show string|| block, type the text "Guess what animal?" to replace "Hello world".

brick.showString("Guess what animal?", 1)

Step 3

Open the ||brick:Brick|| Toolbox drawer. From the Buttons section, drag out an ||brick:on button|| block and put it anywhere in the Workspace.

brick.buttonEnter.onEvent(ButtonEvent.Pressed, function () { 
     
}) 
brick.showString("Guess what animal?", 1)

Step 4

In the ||brick:on button|| block, use the drop-down menu to select the left button.

brick.buttonLeft.onEvent(ButtonEvent.Pressed, function () { 
     
}) 
brick.showString("Guess what animal?", 1)

Step 5

Open the ||brick:Brick|| Toolbox drawer. In the Buttons section, drag out 3 more ||brick:on button|| blocks. Using the drop-down menu, select the right, up, and down buttons for these 3 blocks.

brick.buttonLeft.onEvent(ButtonEvent.Pressed, function () { 
     
}) 
brick.buttonRight.onEvent(ButtonEvent.Pressed, function () { 
     
}) 
brick.buttonUp.onEvent(ButtonEvent.Pressed, function () { 
     
}) 
brick.buttonDown.onEvent(ButtonEvent.Pressed, function () { 
     
}) 
brick.showString("Guess what animal?", 1)

Step 6

Open the ||brick:Brick|| Toolbox drawer. Drag out 4 ||brick:show image|| blocks onto the Workspace, and drop one of them into each of the ||brick:on button|| blocks.

brick.buttonLeft.onEvent(ButtonEvent.Pressed, function () { 
    brick.showImage(images.expressionsBigSmile) 
}) 
brick.buttonRight.onEvent(ButtonEvent.Pressed, function () { 
    brick.showImage(images.expressionsBigSmile) 
}) 
brick.buttonUp.onEvent(ButtonEvent.Pressed, function () { 
    brick.showImage(images.expressionsBigSmile) 
}) 
brick.buttonDown.onEvent(ButtonEvent.Pressed, function () { 
    brick.showImage(images.expressionsBigSmile) 
}) 
brick.showString("Guess what animal?", 0)

Step 7

In the ||brick:show image|| blocks, use the drop-down menu to select a different image to show for each block.

brick.buttonLeft.onEvent(ButtonEvent.Pressed, function () {
    brick.showImage(images.expressionsMouth2shut)
})
brick.buttonRight.onEvent(ButtonEvent.Pressed, function () {
    brick.showImage(images.expressionsMouth1open)
})
brick.buttonUp.onEvent(ButtonEvent.Pressed, function () {
    brick.showImage(images.objectsBoom)
})
brick.buttonDown.onEvent(ButtonEvent.Pressed, function () {
    brick.showImage(images.objectsPirate)
})
brick.showString("Guess what animal?", 0)

Step 8

Open the ||music:Music|| Toolbox drawer. Drag out 4 ||music:play sound effect|| block and drop one of them into each of the ||brick:on button|| blocks, just after the ||brick:show image|| block.

brick.buttonLeft.onEvent(ButtonEvent.Pressed, function () {
    brick.showImage(images.expressionsMouth2shut)
    music.playSoundEffect(sounds.animalsCatPurr)
}) 
brick.buttonRight.onEvent(ButtonEvent.Pressed, function () {
    brick.showImage(images.expressionsMouth1open)
    music.playSoundEffect(sounds.animalsCatPurr)
})
brick.buttonUp.onEvent(ButtonEvent.Pressed, function () {
    brick.showImage(images.objectsBoom)
    music.playSoundEffect(sounds.animalsCatPurr)
})
brick.buttonDown.onEvent(ButtonEvent.Pressed, function () {
    brick.showImage(images.objectsPirate)
    music.playSoundEffect(sounds.animalsCatPurr)
})
brick.showString("Guess what animal?", 0)

Step 9

In each ||music:play sound effect|| block, use the drop-down menu to select a different animal sound to play.

brick.buttonLeft.onEvent(ButtonEvent.Pressed, function () {
    brick.showImage(images.expressionsMouth2shut)
    music.playSoundEffect(sounds.animalsCatPurr)
})
brick.buttonRight.onEvent(ButtonEvent.Pressed, function () {
    brick.showImage(images.expressionsMouth1open)
    music.playSoundEffect(sounds.animalsDogBark1)
})
brick.buttonUp.onEvent(ButtonEvent.Pressed, function () {
    brick.showImage(images.objectsBoom)
    music.playSoundEffect(sounds.animalsElephantCall)
})
brick.buttonDown.onEvent(ButtonEvent.Pressed, function () {
    brick.showImage(images.objectsPirate)
    music.playSoundEffect(sounds.animalsSnakeHiss)
})
brick.showString("Guess what animal?", 0)

Step 10

Now, plug your EV3 Brick into the computer with the USB cable, and click the Download button at the bottom of your screen. Follow the directions to save your program to the brick.

Test your program with a friend by pressing the right, left, up, and down buttons on your brick. Have your friend guess what animal it is!
