My page dedicated to minecraft.

Installation

Minecraft Client

  • http://www.minecrafthasrunoutofmemory.com/13-ways-to-make-minecraft-run-faster/
    • Install Optifine
    • Allocate more memory
      however there is conflicting recommendations there. Probably garbage collector introduce big latency if lots of memory is allocated, whereas smaller memory will trigger the gc more often but with less work. There is an option however to trigger the gc incrementally (-Xinggc)
    • Run in windowed mode
      Sometimes MC freezes in fullscreen, but runs fine in window mode, even maximized!!!
    • Run 64-bit java / Change java provider
  • http://www.minecraftforum.net/topic/343030-minecraft-speedoptimization-guide-v-24-1-updated-on-mar-14-2013/
    • Play on "fast" and "tiny" graphics, turn off clouds, and use Advanced OpenGL
    • Don't Use texture packs bigger than 16x, which is the default resolution
    • Give minecraft more/less memory (384MB for vanilla, 512 when using lots of mods, 2048MB when 100 mods, lots of creatures, etc)
    • Update LWJGL! (LightWeight Java Game Library)

Minecraft Server

The solution was simply to remove the binding to dynamic-complete-history in the .inputrc file.

Press r for Simply Hax Flying, i for Simply Hax Vision.
Not great. Flying is detectable, and vision is mere clipping vision.

See anti-cheat pluggin on Bukkit for counter-weapons ;-)

PvP Tips

Faction bases and TNT

Some techniques and counter-techniques to protect faction bases on PvP server:

  • Regular base can be attacked via regular TNT cannon
  • Usual counter-technique is to use a water wall around the base
  • Hybrid cannon can be used to destroy water wall, although only at the base of the wall.
  • If water wall is at the border of the faction claimed chunk, one can use pistons instead to push blocks in the water. Eg. Push 1 glass block, 1 TNT block on top, and yet another block on top to protect from falling water.
TODO
  • If TNT & sand is falling while overlapping, and TNT explodes while still being overlapped, will the engine consider the TNT be in a water block or in the overlapping sand block?
NOTES
  • Falling sand is not longer a regular block, but an entity handled by the physical engine.
  • Falling sand that hits a slab or similar will break.
IDEAS
  • Foresee an intrusion detection mechanism that will trigger a chest transport system. Like moving the content of the chest to another location. Eg: explode the chest, collect result deep down, use hoppers to move items around, then TNT everything afterwards.
