In this project we are going to learn how to create a program Minecraft that will leave a trail of flowers or a yellow brick road behind you wherever you walk in the world.

First, open Minecraft Education Edition, login, create a new world and open the Code Builder.

Show: Minecraft: Create a new coding project

---

To create a new Minecraft coding project you will need to follow these steps:

1. Open Minecraft Education Edition on your device.
2. Login using your Minecraft account.
3. Click "Create New".
   
4. Click "New".
5. Choose the "Creative" option for the setting "Default Game Mode".
6. Click "Play" (your new world will take a few seconds to be created).
7. Open the Code Builder (the tool we use for creating code in Minecraft) by pressing the C button on your keyboard.
8. Click on the "New Project" button, give your project a name and then click on the "Create" button.
   

Add the following code to leave a trail of flowers behind you, wherever you walk in the Minecraft world.

player.onTravelled(WALK, function () {
    blocks.place(YELLOW_FLOWER, pos(0, 0, 0))
})

As we are using the position 0 0 0, the flowers get created wherever you are. The on player [walk] block triggers whatever code you put inside it when the player walks.

Next update your code as follows to place different types of flowers wherever you walk.

player.onTravelled(WALK, function () {
    blocks.place(POPPY, pos(0, 0, 0))
    blocks.place(ALLIUM, pos(0, 0, 0))
    blocks.place(CORNFLOWER, pos(0, 0, 0))
})

You may have noticed the on player [walk] block can be changed to trigger the code inside it for different things the player can do.

Change the block so that it triggers on player [fly] and then run your code.

player.onTravelled(FLY, function () {
    blocks.place(POPPY, pos(0, 0, 0))
    blocks.place(ALLIUM, pos(0, 0, 0))
    blocks.place(CORNFLOWER, pos(0, 0, 0))
})

To make your player fly, press the space bar twice and then use the w or s keys to move around.

Add the following new code to place a gold block wherever your player walks.

player.onTravelled(WALK, function () {
    blocks.place(GOLD_BLOCK, pos(0, 0, 0))
})

Run your code and make your player walk around. Notice that gold blocks get placed on top of the ground, wherever you walk.
