Display error message

[TheHook]

Is there a way to display a message in a way that is 100% similar to default interface error messages (e.g. "Build a farm", "Must target flying unit", etc.). It is demonstrated in DotA when player tries to attack Roshan from outside the cave.

DisplayTextToPlayer(<player>,1,1, "Message") sort of works, but as soon as there is another message displayed at different screen coords, every text line jumps to that last message's location on screen.

theres no, at all

So how is it implemented in DotA?

clear all text messages, print your text. ugly solution, but if you're ok with that, it's way to go. I hate them for cleaning useful info

I've used this from Vexorian library.

function CS_Error takes player ForPlayer,string msg returns nothing
local sound error=CreateSoundFromLabel("InterfaceError", false, false, false, 10, 10)
  if ( GetLocalPlayer() == ForPlayer ) then
  if ( msg != "" ) and ( msg != null ) then
  call ClearTextMessages()
  call DisplayTimedTextToPlayer(ForPlayer, 0.52, - 1.00, 2.00, "|cffffcc00" + msg + "|r")
  endif
  call StartSound(error)
  endif
call KillSoundWhenDone(error)
set error=null
endfunction

to prevent display other lines at same screen coords.
Use "call ClearTextMessages()" just before the display msg with new coords... put All instructions into local player scope.

Only solution is what Dracol1ch said. SimError is not compatible with printing other messages.

Edit: Better said DisplayText native can't use different x/y values for one player at same time.

Thanks all! Though it buggers me to realize, that robust engine of WC3 is limited in such a basic area as displaying text :O

P.S: It's not over yet! I've noticed, that there is a native error message, that reads "Must target non-decayed corpse" in the game interface editor (variable name: TargetCorpse). Since specific corpses can never be manually targeted by players, this message is effectively never shown in game, and only appears when targeting a spell with only permitted targets being "Corpses". Perhaps, there is a way to trigger this native errormessage via JASS?

If that is the case, "Must target corpse" can be changed into "<Custom error message>" in the interface editor and displayed to player.

no you cant reach this area whatsoever. hardcoded things are hardcoded, unless you have direct access to the game memoery

I use these functions for displaying custom error messages to a specif player:

• Trigger
  • Events
  • Conditions
  • Actions
    • Custom script: if udg_ErrorSound == null then
    • Custom script: set udg_ErrorSound = CreateSoundFromLabel( "InterfaceError",false,false,false,10,10)
    • Custom script: endif
    • Set ErrorMessage = Your Message Goes Here
    • Set ErrorPlayer = (YourPlayerNumber)
    • Custom script: if GetLocalPlayer() == udg_ErrorPlayer then
    • Custom script: call ClearTextMessages()
    • Custom script: call DisplayTimedTextToPlayer( udg_ErrorPlayer, 0.52, 0.96, 2.00, "\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n|cffffcc00"+udg_ErrorMessage+"|r" )
    • Custom script: call StartSound(udg_ErrorSound)
    • Custom script: endif

You need to create a sound variable called "ErrorSound", a player variable called "ErrorPlayer" and an string variable called "ErrorMessage"
