Hi, I'm one of the developers of RusherBot, a chatbot on the popular Minecraft server called 2b2t.
I have a lot of experience making automated walking scripts (random movement too) and chatbots for Minecraft. I can have it done in either node.js or Python, whichever you choose. I believe I'm the only one here so far with actual specific experience in automated movement AND chatbots on one of the most difficult servers to bot!
I set my delivery time as 3 days just in case something comes up, but I'd likely be able to get it done quicker.
Please start a chat with me and we can talk about more details of the bot.
