Hey hey!

I have this portion of the code:
Code:
   if(input ~= "") then
                  for i,v in pairs(Spring.GetTeamList()) do
                  if v > 0 then  -- a check because for some reason when i = 1, then v = 0 and teamID = nil
                  local teamID = Spring.GetTeamList()[v]
                     for j,k in pairs(Spring.GetTeamUnits(teamID)) do --k is unitID
                        if k > 0 then --a check similar to above
                        _,playerID,_,_,_,_,_,_=Spring.GetTeamInfo(teamID)
                        playername,_,_,_,_,_,_,_,_,_=Spring.GetPlayerInfo(playerID)
                        end
                     end
                  end
               end
               Spring.SendLuaUIMsg(msgbox.." Playername;"..playername..";Answer "..counter..";".." "..input)
         end


When i run its errors says: '[f=0000901] LuaUI::RunCallIn: error = 2, MouseRelease, [string "LuaUI/Widgets/gui_pausescreen.lua"]:213: attempt to concatenate global 'playername' (a nil value)'

Does anyone know what I am doing wrong?
It works once before, but it doesn't now.
I am connecting the 2 laptops through wireless.

This makes no sense:
Code:
 for j,k in pairs(Spring.GetTeamUnits(teamID)) do --k is unitID
   if k > 0 then --a check similar to above
   _,playerID,_,_,_,_,_,_=Spring.GetTeamInfo(teamID)
   playername,_,_,_,_,_,_,_,_,_=Spring.GetPlayerInfo(playerID)
   end
 end
The variables of the loop are j and k. But nothing is done with them in the loop. Why do you loop over all units in a team if you just want a playername?

if k > 0 then --a check similar to above
this a bit strange since unitIDs are always positive, so the check is unneeded.
Use Spring.ValidUnitID (unitid) to see if a unitid is valid.

Also you get playername several times but SendLuaUIMsg is outside the loops, so only the last one will ever get send?
What are you trying to do?

in chat? in some textbox you made with lua?
Why is that in gui_pausescreen.lua? help.

Since it is a widget the only player able to click the "send message" or whatever button is the local player. I would use Spring.GetMyPlayerID and pass that to GetTeamInfo

Also the funfact of SendMessage might be of interesst.

Yup. in a textbox i created in lua.
is in gui_pausescreen.lua because the players are writing the message at gamepause, so i merge my textbox with the pausescreen widget.

I manage to get it working. my new code:
Code:
if(input ~= "") then
            if(playercount ==0) then
                  for i,v in pairs(Spring.GetTeamList()) do
                     if v > 0 then  -- a check because for some reason when i = 1, then v = 0 and teamID = nil
                     local teamID = Spring.GetTeamList()[v]
                           _,playerID =Spring.GetTeamInfo(teamID)
                           playername = Spring.GetPlayerInfo(playerID)
                           Spring.Echo("playername")
                           Spring.Echo(playername)
                           playercount= playercount+1
                           break
                     end
                  end
            end
         end
         
            if(playername == nil) then
            --Spring.Echo("nil")
            else
            --Spring.Echo("message")
            Spring.SendLuaUIMsg(msgbox.." Playername;"..playername..";Answer "..counter..";".." "..input)
            --Spring.Echo(msgbox.." Playername;"..playername..";Answer "..counter..";".." "..input)
            end
      input = ""
      end


Do you see if i might have any further problems with the code i write?

this is still wrong.
with the v>0 thing you only mask that the loop is wrong.
I think it should be
for _ ,teamID in ipairs(Spring.GetTeamList()) do

has to do with tables, key/values bla, a Lua tutorial can explain better than me.

Quote:
if(playercount ==0) then
since I can not see the whole widget, I have no idea what this does, among other things.
Why is there a break in the loop?

Hey!

Thanks!
I manage to further edit the code.
Thanks for the tip on Spring.GetMyPlayerID!
