Minecraft Round Up - Let's mod a TNT Rocket Launcher
This week we are continuing our 'Redstone Contraption' series and are coding an EXPLOSIVE TNT Rocket Launcher!
Welcome to Minecraft Mod Club! This week we are continuing our 'Redstone Contraption' series and are coding an EXPLOSIVE TNT Rocket Launcher!
In this mod, we are using red stone dust as well as the help of our coding agent to create a TNT Rocket Launcher. Once the mod has been built, all the player needs to do is use the button the activate the piston which launches off our TNT block. Our agent then replaces the TNT block with another, so we are loaded and ready for the next round.
To build this mod, we create two functions; one for the base and one for the launcher. The base is made up of obsidian blocks along with a trail of redstone whilst the launcher spawns the piston as well the initial TNT block. On command 'T' we call those two functions and activate a coding block that places the agent next to the TNT.
We then have an boolean which checks whether there if there is a TNT block next to the agent; if false then the agent will place a new TNT block there given you infinite ammo!
This mod is great if you are playing Capture The Castle in your Minecraft World - or if you want a more creative (and destructive!) way to mine...
Until next time, happy building everyone!
About Minecraft Mod Club
Minecraft Mod Club uses Minecraft Education Edition to teach real code. Children write mods rather than just playing: custom blocks, new behaviours, things the game does not do out of the box. For a child who would happily spend all weekend in Minecraft, it is usually the easiest way in.
It is included with every membership rather than sold separately. Sessions are one hour a week in a group of no more than six, with the same DBS-checked, STEM-certified mentor, and children build their own projects rather than following a set course. Most start in Scratch or MakeCode and move to Python and TypeScript when they are ready.
Modding is a good bridge because the feedback is immediate and visible: change the code, reload the world, see whether the block behaves. That makes the jump from block-based coding to written code less abrupt than it usually is, which is the point where most children stall when they are learning alone.
Mentors write a note on every child after every session, so we know when somebody is ready to move up a level or would rather stay put.
More than a third of our members are autistic or have ADHD, based on what parents tell us when they join, and in 2025 we received the Autism Inclusion Award from the National Autistic Society. Children can keep the camera off, type instead of speaking, and take a break without it disrupting anyone.

The blog is in two halves. Guides are the evergreen explainers written by the mentors who teach the clubs, covering the questions parents actually ask: what comes after Scratch, how to support a coding-mad child when you cannot code yourself, and what works for autistic and ADHD children.
Club news is the other half, and it is where posts like this one live: game jams, Minecraft builds and weekly roundups, written up by whoever ran the session. Neither is marketing. If you want to know what an hour actually looks like before you book anything, club news is the more honest read of the two.
The first session is a free taster and we do not ask for card details. Book a free taster session, see what it costs, or read about support for neurodivergent children.
