Action Agent ai message
Explain: Since your inventory is empty and there are no nearby entities or chests, you will need to collect the wood log manually by mining it.

Plan:

1. Use the mineBlock(bot, name, count) function to mine the wood log. Pass the name of the log you want to mine as the name parameter and set count to 1.
2. Check if you have the wood log in your inventory. If not, repeat step 1 until you have it.

Code:

async function mineWoodLog(bot) {
  const logName = "oak_log"; // Change this to the type of log you want to mine
  const logCount = 1;

  while (true) {
    // Check if you already have the wood log in your inventory
    const woodLog = bot.inventory.findInventoryItem(mcData.itemsByName[logName].id);
    if (woodLog) {
      bot.chat(`I already have ${logName} in my inventory.`);
      break;
    }

    // Mine the wood log
    bot.chat(`Mining ${logName}...`);
    await mineBlock(bot, logName, logCount);
  }
}

mineWoodLog(bot);

Explain: The task is to craft 1 crafting table. To craft a crafting table, we need four wooden planks.

Plan:

1. Check if there are enough wooden planks in the inventory.
2. If there are not enough wooden planks, mine oak logs until we have enough.
3. Craft the wooden planks into a crafting table.

Code:

async function craftCraftingTable(bot) {
  // Check if there are enough oak planks in the inventory
  const oakPlanksCount = bot.inventory.count(mcData.itemsByName.oak_planks.id);

  // If not, craft oak planks from oak logs
  if (oakPlanksCount < 4) {
    const oakLogsCount = bot.inventory.count(mcData.itemsByName.oak_log.id);
    const planksToCraft = Math.ceil((4 - oakPlanksCount) / 4);
    if (oakLogsCount >= planksToCraft) {
      await craftItem(bot, "oak_planks", planksToCraft);
      bot.chat("Crafted oak planks.");
    } else {
      bot.chat("Not enough oak logs to craft oak planks.");
      return;
    }
  }

  // Craft a crafting table using oak planks
  await craftItem(bot, "crafting_table", 1);
  bot.chat("Crafted a crafting table.");
}

// Call the function
await craftCraftingTable(bot);
