    I have a button that when the cursor enters the button area it shows a Tooltip, this works good, the tooltip shows a message.

    Now what i want to do is I want to add to that message the name of the targeted player or unit, this also works well. The problem i am having is if there is no targeted player then i want the message to say something completely different and this is where i am having problems.

    this is what i have that works:

     if(UnitIsUnit("target", "player")) then -- player has self targeted
   EmoteForTargetTooltip(owner, playerString);
 else -- someone else is targeted.
   EmoteForTargetTooltip(owner, targetString);
 end

    this code works as intended, but what it doesnt do is send the tooltip to the player without a target.

    I tried:

     if UnitName("target") then
    -- Do something if the name exists
    print("target does exist");
  else
    -- Do something if it doesn't exist
    print("target does not exist");
  end

    with the above code if I have any unit targeted the if statement does process its print statement but the else never processes even if i dont have a target.

    ie.. I reload the UI, and i immediately move my mouse over the button while i have no target, nothing happens, so i click on my own profile and it then shows that i have myself targeted, so i move the mouse over the button again and this time the print statement does work it shows me the "target does exist" statement.

    I also tried:

     if(UnitExists("target")) then
   print("target does exist");
 else
   print("target does not exist");
 end

    Here I have the exact same problem with the exact same results, as long as I have any unit targeted then the print statement print("target does exist"); processes fine, but without a target i get nothing.

    The UnitIsUnit If statement does what i need it to do if something is targeted but I also need to check if the player does not have any unit targeted and if not then do something.

    with UnitName("target") and UnitExists("target") the else statements never seem to process, can anyone suggest a course of action for me?

    Is there another way to do what i want to do?

    Thanks for any help you can give.

    Your statement is confusing me a bit, but here's what I'm reading. If you want to add a message if the player has someone other than themselves targeted, and a different message if the player has no one targeted, you can do this:

     if UnitExists("target") then
   if UnitIsUnit("target", "player") then
     -- the target is the player, so do nothing
   else
     -- display the target information in the tooltip
   end
 else
   -- the player does not have anyone targeted
 end

    Thank you for your quick reply.

    I tried your code with no success, I still have the same problem.

     if UnitExists("target") then
   if UnitIsUnit("target", "player") then
     EmoteForTargetTooltip(owner, playerString); -- EXAMPLE 1
   else
     EmoteForTargetTooltip(owner, targetString); -- EXAMPLE 2
   end
 else
   EmoteForTargetTooltip(owner, playerString); -- EXAMPLE 3
 end

    If i have myself targeted then Example 1 runs, if I have someone else targeted then Example 2 runs, but if i dont have any target nothing happens, Example 3 never runs.

    something i dont understand though is I took the following code:

     if(UnitName("target")) then
   print("1");
 else
   print("2");
 end

    put it in the xml file Buttons OnEnter script and it ran fine both the if and the else worked fine but when i took the same code and put it in my lua file the else would not process, is there something im doing that could make this happen?

    The issue is then somewhere else in your logic and that's very difficult for me to troubleshoot. The conditional I gave you works properly and you can test this with the following macro:

    /run if UnitExists("target") then if UnitIsUnit("target", "player") then print("player targeted") else print(UnitName("target") .. " is targeted") end else print("no target") end

    Just put that on your action bar, and you'll be able to see that it properly handles all three cases. I'd suggest ensuring that Lua Errors are enabled (Interface Options -> Help -> Display Lua Errors) to ensure you're not missing an error message somewhere. There is no need to use UnitName, the UnitExists and UnitIsUnit functions do exactly what you want them to do.

    Ive done some more troubleshooting of sorts,

    the button i have has OnClick and OnEnter defined in the Scripts Tag of the xml file.

    I added the following code to both OnClick and OnEnter In the Xml file:

       if(UnitName("target")) then
     print(GetUnitName("target"));
   else
     print("unit is nil or doesnt exist");
   end

    when i saved and reloaded the UI then moved my cursor over the button to invoke the OnEnter or when I clicked the button to invoke the OnClick, both times the If and Else worked fine, but when i put the code into thier respective functions in the lua file the OnClick still worked fine but the OnEnter would not process the else statement.

    here is the function that my OnClick goes to in the lua file:

     function Emote_OnClick(string)
   DoEmote(string);

   if(UnitName("target")) then
     print(GetUnitName("target"));
   else
     print("OnClick, unit is nil or doesnt exist");
   end
 end

    Both the If and the Else works above.

    Here is the function that my OnEnter goes to in the lua file:

     function Emote_OnEnter(owner)
   local green = "|cFF00FF00";
   local playerString = green .. "You applaud. Bravo!";
   local targetString = green .. "You applaud at < " .. UnitName("target") .." >. Bravo!";

   if(UnitName("target")) then
     print(GetUnitName("target"));
   else
     print("OnEnter, unit is nil or doesnt exist");
   end

   if UnitExists("target") then
     if UnitIsUnit("target", "player") then
      EmoteForTargetTooltip(owner, playerString); -- EXAMPLE 1
     else
      EmoteForTargetTooltip(owner, targetString); -- EXAMPLE 2
     end
   else
     EmoteForTargetTooltip(owner, playerString); -- EXAMPLE 3
   end
 end

    In the Above only the "if(UnitName("target")) then" part works, the Else wont process.

    Why does it work for one method but not for another? have i done something wrong?

    Thank you for your help, I didnt know how to enable viewing of lua errors, after i enabled it I got some errors right off the main problem led me right to what was giving me so much stress tonight.

    the line:

    local targetString = green .. "You applaud at < " .. UnitName("target") .." >. Bravo!"; was defined at a point where if there was no target it would try to concatenate a nil value in the middle of the string. ie.. UnitName("target"), btw i changed that to GetUnitName.

    after moving that line down inside the [ if UnitExists("target") then ] check it finally worked, i have sure found out that logic can be a killer with lua. Thanks for your help, Ive spent way too much time up tonight, time for bed. lol at 7:47 in the am. lol
