Edit signs - misiek - 10-02-2014

Is it possible to programaticaly (by code) change sign text?

I wonna show status of few places that are around city in city hall on signs. Is it possible with MCSever and Lua plugin?

Have a look here: http://mc-server.xoft.cz/LuaAPI/cSignEntity.html

Usually you need to do something like this:

-- World is the cWorld of the sign, X, Y, Z are the sign's coords
World:DoWithBlockEntityAt(X, Y, Z,
  function (a_CBBlockEntity)
    local BlockType = a_CBBlockEntity:GetBlockType()
    if ((BlockType == E_BLOCK_WALLSIGN) or (BlockType == E_BLOCK_SIGNPOST)) then
      local Sign = tolua.cast(a_CBBlockEntity, "cSignEntity")
      Sign:SetLines("line1", "line2", "line3", "line4")
    end
  end
)

Note that I wrote this code off of my head, might not work Smile

I wonna edit sign in existing world, so cSignEntity itself it's not for me Smile

Thank, I'll try it.

If you want to edit signs in an existing world you have to use cWorld:SetSignLines(a_X, a_Y, a_Z, a_Line1, a_Line2, a_Line3, a_Line4, [cPlayer])
The player parameter is optional.

Right, STR_Warrior got the right answer, I completely forgot about that function.

The code I gave you should work as well, but is needlessly complicated.
