Here is the state of our mods and the changes planned for them.

OpenModularTurrets

v4.2.x (planned)

The targets of 4.1.x and 4.2.x are the issues of the matching milestones in the issue tracker. Which Minecraft versions get 4.1.x and 4.2.x is not decided yet.

  • Add: multiblock bases and their blocks, which replace the upgrades (#493):
    • basic blocks without a function (maybe basic and advanced)
    • cooling block (air/fluid cooling) that replaces the fire rate upgrade, and vents as an attachment
    • power converter block that replaces the efficiency upgrade
    • targeting systems that replace the accuracy and range upgrades
    • ammo compressor block that replaces the scattershot upgrade
    • energy generating blocks, with a rework of the energy generation in bases
  • Change: some turrets and addons need a certain size or features of their multiblock base
  • Add: a way for mobs to fight turrets, by destroying or deactivating them; only hostile mobs would attack (#531)
  • Change: concealing a turret without the addon becomes a per-turret setting, e.g. with a GUI button or OMLib’s wrench, instead of a global config option (#458)

v4.1.x (planned)

A visual rework of the mod with a clear material and engineering progression, and some changes to addons and blocks.

  • Change: turret models and textures follow the material progression wood → copper → brass → iron → steel, the swivel holders are remodelled to fit, and every turret gets visual indicators that make it easy to identify at night (#586)
  • Change: Gun Turret: less military, brass tier, new model (#579)
  • Change: Grenade Turret: new texture (#580)
  • Change: Slowing Turret (the former Relativistic Turret): new model and texture (#581)
  • Change: Rocket Launcher Turret: new model and texture (#582)
  • Change: Laser Turret: new model and textures, a crystal laser with a big cooling system (#583)
  • Change: Plasma Turret: fix the coil rendering, new model and texture (#584)
  • Change: Potato Cannon Turret: a hole in front of the barrel (#585)
  • Change: the Damage Amp addon is shown as a glowing wavy ring on top of the base plate of the turret (#587, with a pull request open: #591)
  • Add: heat system (#590):
    • turrets produce heat, some none or only a little, some a lot
    • bases store heat and turrets cannot shoot while the storage is full
    • bases lose heat through every free side, and a cooling fan on one side dramatically increases that (the block two blocks from the base on that side must be air)
    • heat generation of turrets, storage and dissipation of bases and an on/off switch are in the config
  • Change: the Solar addon becomes a block with a higher energy output (#578)
  • Change: more realistic turrets: a configurable range damage falloff (optimal range plus falloff) and tracking limits, so fast spinning railguns no longer make sense (#539)
  • Change: recipe rework: new intermediate items, the previous tier is removed from the recipes, the cost stays the same and the crafting needs fewer steps (#595)
  • Add: Repelling Turret (Tier 3) (Entity pushing utility turret) (#324)
  • Add: Tractor Turret (Tier 3) (Entity pulling utility turret) (#324)
  • Add: Energy Drain Turret (Tier 5) (Drains energy from the items of its targets) (#324)
  • To consider: Particle Beam Turret (Tier 5) (Very high damage, very low firerate, large AOE offensive turret) (#324)
