Hat ein Fahrzeug einen Motor?

Recommended Posts

  Hello Members
  
  Please can someone help me with the following.
  I am trying to build a table containing all the Locomotives
  in the layout. I cannot find the Lua code corresponding to
  "the vehicle has an engine" in the following:  
  
  function GetAllLocos()
      local tt = {}
      g = layout:enumVehicles(
      function ( vehicle )
         if "the vehicle has an engine" then
           table.insert(tt,vehicle)
         end
      end
      )
      return tt
  end
  
  I have searched the forum for quite a long time before making
  this request. I hope some kind person will tell me the solution.
  
  Thank you
  
  Eric

Thank you HaNNoveraNer

I had a memory of "hasEngine" but I was trying vehicle.hasEngine. Once again: thanks for your quick reply.

Best wishes

Hello Eric,

I don't know if you know this

for information

all Lua functions and properties are documented directly in the script editor by auto-completion Press colon (:) for a list of all functions, 
dot (.) for a list of all properties and 
CTRL+space for an overview of all global variables and parameters.

NEO has answered a question from TIMBA
every vehicle has the function "hasEngine", with which you can check if it is a powered vehicle

local vehicles = layout:getVehiclesOnTrack(...)
for k, v in pairs(vehicles) do
  if v:hasEngine() then
    -- Vehicle ist eine Lok
  end
end
 

Best wishes

Hello Martin

I tried .(dot) CTRL+space but not :(colon) CTRL+space. I won't make that mistake again!

Best wishes

That would be a variable or property. Separated by a single colon.

The double colon is needed for a function or method. It includes the object (= what's in front of the colon) as the first argument.
