Dota's error messages

[Genyuumaru]

The yellow ones like when you give a wrong order. How are they made?

 

[Expelliarmus]

function SimError takes player ForPlayer, string msg returns nothing
    if udg_SimError==null then
        set udg_SimError = CreateSoundFromLabel("InterfaceError", false, false, false, 10, 10)
    endif
    if GetLocalPlayer() == ForPlayer then
        call ClearTextMessages()
        call DisplayTimedTextToPlayer(ForPlayer, 0.52, -1.00, 2.00, "|c00FFCC00" + msg + "|r")
        call StartSound(udg_SimError)
    endif
endfunction

Global SimError sound variable required

most are from Gamplay Interface, theres preset errors for certain things, just change the text.

I thought of that, but I need more info.
Like how is it done?

Does it create a dummy unit and orders it a false order or something?

 

[cleeezzz]

what errors are we talking about? theres errors like, this unit is spell immune, which is hardcoded, you dont need a dummy (also Pudge's ultimate says "This unit is already leashed" if you try to ulti the same unit twice, same with Rhasta's leash. these are hard coded)


stuff like Puck's etheral jaunt? will probably use the code mentioned above.

For example - the ability to show an error message that you don't need to buy the recipe on some items.
