What's new

I recommend always making backup of your world before updating anything.

Disclaimer: I cant possibly test all the modloaders with all the Minecraft versions so most of them are copy pasted code from the newest version on neoforge, fixed to compile and not tested in game. If you encounter bugs please report them on discord below thanks.

Please report issues to my discord https://discord.gg/y366spsSjv

1.5.0

  • Standard Light power use rebalanced: it now really uses what its GUI always showed - 120 J/t basic, 240 advanced, 360 elite and 480 ultimate

    • Set with the new config key STANDARD_LIGHT_ENERGY_PER_TICK (Joules per tick times the tier)
    • BASIC_LIGHT_CONSUMPTION is no longer used if you changed it, put the same number in STANDARD_LIGHT_ENERGY_PER_TICK
  • Standard Light now accepts Mekanism Energy Upgrades.

  • Tier Installers now work on Standard Lights and keep the stored energy, the battery in the slot, on/off state, redstone mode, security and installed upgrades

  • Standard Lights no longer stay dark after a world reload when RECALC_LIGHT_SWITCH is set to true

  • Raising a Standard Light range in the config now also grows lights that are already placed

  • Grass, flowers, torches, rails and anything else you can walk through no longer block light

  • Light source blocks no longer show up on maps, no longer get pushed around by pistons, no longer stop saplings from growing, are never placed next to obsidian and move out of the way when you build an obsidian frame around them (so they can't block a nether portal)

    • Forge: light now also reaches high up into open air
  • tags: thanasmekanismlights:light_passable, thanasmekanismlights:light_blocking and thanasmekanismlights:light_avoid

  • Light source blocks now clean up better after themselves

  • Better behavior when multiple lights in close proximity

  • The light multiblock no longer turns all its lights off and back on every time its chunk unloads and reloads

  • The light multiblock now remembers its range and on/off state when its structure is broken and repaired

  • Lights no longer force far-away chunks to load while checking line of sight, and a light whose range reaches past the loaded area no longer makes the server load or generate the chunks next to it

  • Changing the light spacing or range in the config no longer leaves the light multiblock old light blocks behind after a restart

  • Light source blocks no longer affect blocks around them when they appear or disappear (no more block updates for floating sand, gravel or observers)

  • Sneak right clicking a Standard Light now respects Mekanisms security

  • Energy usage shown in the GUIs now comes from the server config

  • fixed redstone control

  • Fixed the config adding RECALC_TICK=4 instead of its real default of 10 when the key was missing (existing values are left as is)

  • new mod logo/icon
