What Animal Am I?

Introduction

Create different animal effects with your LEGO® MINDSTORMS® Education EV3.

Guess the what the animal is

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 the animal" to replace "Hello world".

brick.showString("Guess the animal", 1)

Step 3

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

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

Step 4

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

Dropdown with button choices

brick.buttonLeft.onEvent(ButtonEvent.Pressed, function () { 
     
}) 
brick.showString("Guess the 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 the 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 the 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.

Dropdown with image selection

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 the 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 the animal", 0)

Step 9

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

Dropdown with sound effect selection

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 the animal", 0)
