Open Modular Turrets

[4.0.0-alpha.1] - 2026-10-23

Added

• The Melee Turret has a model: its blades extend and spin while something is in reach
• Generator: burns furnace fuel into energy for adjacent turret bases, with 9 fuel slots and an upgrade slot for the new Energy Multiplier upgrade (each doubles output and fuel use); placed 3.x power generators become generators and keep their fuel
• Turret API for other mods (@OMTPlugin.Register, api and api.weapon, client models via @OMTClientPlugin.Register); added turrets get their config in config/openmodularturrets_addon_turrets.cfg, see docs/turret-api.md

Fixed

• The Melee, Relativistic and Teleporter Turrets crashed the game when they were saved (3.2.0 alpha)
• Player kills of a base are counted and saved (they were loaded into the kill counter and never saved)
• The neutral force list config was read into the mob block list
• Turrets on auto fire took the ammo of a shot twice
• Forced shots of Laser, Arc and Railgun Turrets crashed the game without a target and ignored missing energy
• The Grenade Turret was only available while the Laser Turret was enabled in the config
• The Crossbow Turret's config section had the name of the Potato Cannon Turret's; it is "Crossbow Turret" now
• Rays of Laser, Railgun and Arc Turrets could hit entities next to the ray
• The Plasma Turret tooltip showed tier 3, although the turret needs a tier 5 base
• The configure GUI no longer draws its buttons below its background
• The info panel of the turret base GUI no longer covers the GUI when its lines are long (e.g. long player names)

Changed

• Pets of players in the owner's scoreboard team are no longer targeted, and team members no longer get turret warnings
• Turret bases pick the targets of their turrets and drop a target as soon as it is no longer valid (out of range or sight, trusted, settings changed)
• Targeting priorities are added up instead of multiplied and use the real distance, so turrets prefer the targets their priorities describe
• The mob block list config is honoured, and the neutral force list wins over the mob force list
• Turrets no longer target entities they would have to aim into their own base for (more than 45° below the mounting side)
• Only blocks with a collision box block the view of turrets, and turrets no longer see through their own base
• The recycler addon saves ammo with the configured chance (it saved about 1 % of shots whatever the config said)
• The solar panel addon charges a base once per tick instead of once per tick for every turret on it
• Pets are protected by the trust list of their owner also while the owner is offline
• The Railgun Turret ignores scattershot upgrades; Melee, Slowing and Teleporter Turrets no longer use more energy with them
• Turret bases no longer give their energy to other blocks
• The Relativistic Turret is now the Slowing Turret; placed turrets, items and its config section are converted
• Turrets aim relative to the side of the base they sit on, the same way on server and client, and turn smoothly
• Projectile turrets lead moving targets using the real flight time and drop of their projectiles
• Projectiles scatter by a fifth of the turret's inaccuracy instead of a twentieth
• The Melee Turret strikes everything it may hurt around itself and its base (3x2x3 blocks) without waiting for the base to pick a target
• The Melee Turret only fits on top of or below a base; melee turrets on the sides of a base drop as items
• The Arc Turret can be placed on every side of a base, not only on top
• The particles of the Teleporter Turret are shown in multiplayer too
• Mobs killed by turrets drop nothing unless the base has a fake drops addon (each further addon adds a level of Looting); the config options doTurretsKillsDropMobLoot and doLootAddonsOverrideMobLootSetting are gone
• Turret tooltips show what the turret does, the base tier it needs, its ammo and its energy per shot; turrets that ignore scattershot upgrades say so without shift
• The camouflage of a turret base is set in the new camouflage menu (Configure → Camouflage), which also holds the light sliders of tier 4 and 5 bases; right-clicking a base with a block no longer camouflages it
• The memory card needs the admin access level to copy and to write settings, also stores the camouflage, works on camouflage traps, and its tooltip shows what it holds; sneak-clicking anything else clears it (3.x cards still work)
• The Turret Memory Card is now called OM Memory Card

Removed

• Inventory and power expanders: they disappear from worlds, together with the items in them
• The loot deleter base addon (turret kills drop nothing without a fake drops addon now); placed loot deleters disappear
• The power generator attachment (it had no function); it is replaced by the generator
• The base controller API (IBaseController, ILaserController) of the discontinued OMTControl addon## [3.2.0]
• The entity and ammo lists of the 3.x API (api.lists): they no longer affected targeting; the config lists and the disposable ammo allow list stay

• A priority system for turrets and reworked targeting largely
• Turret max amount info to tooltips on bases/turrets
• Config to disable ammo usage on turrets

Changed

Fixed

• Energy usage was not settable to zero
• Crash when ray tracing turrets hit multipart entities (such as the ender dragon)
• Computer Craft missing functions added and bugged ones fixed
• Inventory expanders only having half of their intended stacksize limit
• Lots of targeting bugs fixed
• Accuracy now scales a bit better and won't reach a 100% anymore (except on 0 deviation turrets)
• Range now properly updates when putting in or taking out range upgrades
• Some tooltips errors fixed
• Turrets dropping when tile entities placed/removed next to them
