Cloning a Unit's Order Queue

[Argh]

Um... I'm having trouble with something that's so simple, it's annoying. I just want to exactly copy the orders of one unit to another, sans the "tag".

So, I've written the code like this, where u == the unitID of the unit I want to copy from, and k == the unitID of the unit I want to copy to:

local cmds = Spring.GetUnitCommands(u)
Spring.GiveOrderArrayToUnitMap(k,cmds)

... isn't it supposed to be that simple? Or am I missing something here? Sorry in advance, I can't seem to find an example that actually works when I use it.

For a start unitmap takes a table as the first arg, tried

local cmds = Spring.GetUnitCommands(u)
Spring.GiveOrderArrayToUnitMap({k},cmds)

?

That might be complete rubbish, its 4.45am

[Argh]

Meh, that didn't work, either... hmm...

Code: Select all

  --copy command queue
  local cmds = Spring.GetUnitCommands(unitID)
  for i = 2, cmds.n do  -- skip the first command (CMD_MORPH)
    local cmd = cmds[i]
    Spring.GiveOrderToUnit(newUnit, cmd.id, cmd.params, cmd.options.coded)
  end

Is how it's done in the morph gadget

[Argh]

Yeah, I tried that earlier, it didn't work, either. Something must be screwy about how I'm going about this, lemme take another look.

Here's mine from a Gadget i haven't released, should work out of context (target should be a unit with no orders)

Code: Select all

local function copyCommandQueue(targetID, unitID)

  local states = Spring.GetUnitStates(targetID)

  if (states ~= nil) then
    Spring.GiveOrderToUnit(unitID, CMD.FIRE_STATE, { states.firestate }, 0)
    Spring.GiveOrderToUnit(unitID, CMD.MOVE_STATE, { states.movestate }, 0)
    Spring.GiveOrderToUnit(unitID, CMD.REPEAT,     { states['repeat']  and 1 or 0 }, 0)
    Spring.GiveOrderToUnit(unitID, CMD.ONOFF,      { states.active     and 1 or 0 }, 0)
    Spring.GiveOrderToUnit(unitID, CMD.CLOAK,      { states.cloak      and 1 or 0 }, 0)
    Spring.GiveOrderToUnit(unitID, CMD.TRAJECTORY, { states.trajectory and 1 or 0 }, 0)
  end
  
  local queue = Spring.GetCommandQueue(targetID);
  
  if (queue ~= nil) then

    for k,v in ipairs(queue) do  --  in order
      local opts = v.options
      if (not opts.internal) then
        local newopts = {}
        if (opts.alt)   then table.insert(newopts, "alt")   end
        if (opts.ctrl)  then table.insert(newopts, "ctrl")  end
        if (opts.right) then table.insert(newopts, "right") end
        table.insert(newopts, "shift")
        Spring.GiveOrderToUnit(unitID, v.id, v.params, opts.coded)
      end
    end
  end

  local buildqueue = Spring.GetRealBuildQueue(targetID)
  if (buildqueue ~= nil) then
    for udid,buildPair in ipairs(buildqueue) do
      local udid, count = next(buildPair, nil)
      Spring.AddBuildOrders(unitID, udid, count)
    end
  end
  
end

I got it working, finally. I've found that Units don't get their CommandQueue before StartMoving() runs, though. Might be a useful factoid for people out there.

I have a problem with this too to get the widget I last mentioned.

Code: Select all

function widget:CommandNotify(commandID, params, options)
 Spring.GiveOrderToUnit(unitID, CMD.FIGHT, params, options.coded)
return true

Off course there is much more to the code but I took out the only thing that isn't working. In one way it works. The unit gets the order but it just ignores "alt", "ctrl", "shift", "right" options.
