In this project we are going to learn what a Minecraft agent is and how you can use it to help you do things in Minecraft.

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

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.
   

The agent is your assistant who helps you do things in Minecraft. You command the agent with the agent blocks.

Your agent appears when you teleport it to you. When you have your agent, it can do work for you. Give things from your inventory to your agent and have it build stuff for you.

You make your agent go in different directions by moving, turning, and detecting blocks in the way.

First let's make the agent to come the position in the Minecraft world that we are in.

Create a command called summon and give it this code.

player.onChat("summon", function () {
    player.say("Hey Agent!")
    agent.teleportToPlayer()
})

Go to your world and run the summon command. The agent should come to you.

To run a Minecraft command follow these steps:

1. Go into your Minecraft world (close the code editor).
2. Type t to open up the chat.
3. Type in the name of your command, for example "jump".
4. Press enter or press the chat button. Your command and the code inside it will be run.

Next let's create a command to make the agent dig a certain number of levels that we tell it to.

For each level the agent will repeat the following 4 times:

• move forward 1
• if there is a block underneath, destroy it
• collect the material
• turn left
• move down to the next level

Add the following code to create the command.

player.onChat("dig", function (levels) {
    for (let i = 0; i < levels; i++) {
        for (let i = 0; i < 4; i++) {
            agent.move(FORWARD, 1)
            if (agent.detect(AgentDetection.Block, DOWN)) {
                agent.destroy(DOWN)
                agent.collectAll()
            }
            agent.turn(LEFT_TURN)
        }
        agent.move(DOWN, 1)
    }
})

Now run the command in your world (e.g. "dig 3" to dig 3 levels down) and watch the agent dig down the number of levels you specified. Try it a few times with different levels.

Now let's make the agent build something!

Create a command called tower and add the following code to it to make the agent build a tower 10 blocks high.

player.onChat("tower", function () {
    agent.move(FORWARD, 5)
    agent.setSlot(1)
    agent.setAssist(PLACE_ON_MOVE, true)
    agent.setAssist(DESTROY_OBSTACLES, true)
    for (let i = 0; i < 11; i++) {
        for (let i = 0; i < 4; i++) {
            agent.setItem(SANDSTONE, 16, 1)
            agent.move(FORWARD, 4)
            agent.turn(LEFT_TURN)
        }
        agent.move(UP, 1)
    }
})
