Happy-Artillery

Description

Happy Artillery lets you fire from a Happy Ghast's pilot seat, turning your ride into flying artillery. You can launch fireballs and make it scream between shots, but keep an eye on the heat (overheating can cost you the ghast).

Install it on your Fabric server and everyone can use it without installing a client mod.

Take aim

As the pilot, right-click with Fire Control to shoot, or hold to keep firing. Use Cry Control to make the ghast scream between shots.

Controls appear when you take the pilot's seat. Leave two inventory slots free, then move them wherever you like in your hotbar or offhand. Dismount and ride again to replace a lost control.

Your controls, your layout.

Watch the heat

Every rider can see the heat and cooling rate on the HUD, so you can tell when to stop firing and give your ghast time to cool. Short bursts help keep the heat down.

Cold areas and the End cool faster; hot areas cool more slowly. The Nether has no passive cooling by default.

Reach the heat limit and your ghast explodes, scattering fireballs. By default, it doesn't survive. Shots and overheat can damage terrain.

One shot too many.

Configuration

Start the server once to generate config/happy-artillery.json, then open it to change controls, firing speed, heat, overheat effects and the HUD.

For example, set shotCooldownSeconds under fire to 0.5 for half a second between shots, or raise limit under heat to 150 to allow more heat before overheating:

{
  "fire": { "shotCooldownSeconds": 0.5 },
  "heat": { "limit": 150 }
}

This also works as a complete config; omitted settings use their defaults. Save it as valid JSON without comments, then run /ha reload as an operator. Invalid settings leave the previous configuration active.

See the configuration guide for control rules, terrain damage and upgrades, or the annotated settings reference for every option and default.

Installation

For Minecraft 26.3, use Happy Artillery 1.2.1.1, Fabric Loader 0.19.5+, Fabric API and Java 25+. For Minecraft 26.2, use 1.2.0.

• Multiplayer: install Happy Artillery and Fabric API in the server's mods folder.
• Single-player: install both in your Fabric client's mods folder.

Upgrading? Remove the old JAR first. See the upgrade notes for config migration.
