Special Effect for One player

How to create a special effect only for one player?

 

[Komaqtion]

This cannot be done strictly in GUI, you will need JASS for it...

But this is how it would look in JASS:

function AddSpecialEffectForPlayer takes string sfxpath, real x, real y, player p returns effect
    local string path = ""
    
    if GetLocalPlayer() == p then
        set path = sfxpath
    endif
    
    return AddSpecialEffect( path, x, y )
endfunction

 

[Laiev]

function AddSpecialEffectForPlayer takes string sfxpath, real x, real y, player p returns effect
    local string path = sfxpath
    
    if GetLocalPlayer() != p then
        set path = ""
    endif
    
    return AddSpecialEffect( path, x, y )
endfunction

Koma your can desync if is the first time that the string is used

 

[Komaqtion]

I always say the wrong one XD
Thanks, Laiev

Is this showing or creating? I don't really can say how can only player see the effect and another not to. Even in JASS, this possible?

    • Custom script: if GetLocalPlayer() != GetTriggerPlayer() then
    • Set Path = <Empty String>
    • Custom script: endif
    • Special Effect - Create a special effect at (Center of (Playable map area)) using Path

Yea but I am talking about SHOWING an effect to only one player without other players seeing it.

Then READ the trigger again.

Then READ the trigger again.

I don't GET this:

• Custom script: if GetLocalPlayer() != GetTriggerPlayer() then

local player Not Equal to Triggering Player? does a local variable in jass prevent other players from SEEING the effect in game?
I'm not a jasser btw, so this is wild guess.

Okay, first:

Abilities\Spells\Human\ThunderClap\ThunderClapCaster.mdl

This if the path of thunder clap effect, as you probably now.

if GetLocalPlayer() != GetTriggerPlayer() then

If local player(take a look at here: http://www.thehelper.net/forums/showthread.php?t=89207) not equal to triggering player change Path string variable.But Path variable is still same for Triggering player.So, for other players, it is something like,

• Special Effect - Create a special effect at (Center of (Playable map area)) using "Empty String"

but for triggering player,

• Special Effect - Create a special effect at (Center of (Playable map area)) using Abilities\Spells\Human\ThunderClap\ThunderClapCaster.mdl

the local player is always you.
imagine a game with 3 players, on your computer the local player will be you and not the other 2 guys.
however for the second player the local player variable will be himself and not you. that means this variable is set to a different value for every player in the game.

with this method you are not "showing" the effect only for one player but you are "creating" it only for one player. because on every players computer it will compare whether the local player is the triggering player.
since the triggering player is the same on all computers but the local player is always different the comparison will result "true" only for one player.

Gotcha. This creates effect for the one player.

However I still think there is no way to hide a special effect from other players and only happen for one player and only that player to see it. In game of course

You can test it whenever you want =)

 

[Komaqtion]

This creates an effect for EVERY player, but only the specified player (In this case the triggering player) actually has a path for the effect, meaning that it will only show the effect for the triggering player

>Koma your can desync if is the first time that the string is used
So how do you use it properly again? You should use global strings?

 

[Komaqtion]

Nah, you use what Laiev posted:

function AddSpecialEffectForPlayer takes string sfxpath, real x, real y, player p returns effect
    local string path = sfxpath
    
    if GetLocalPlayer() != p then
        set path = ""
    endif
    
    return AddSpecialEffect( path, x, y )
endfunction

The only difference is that in mine you set the path to "" first, and if local player is the one you want, you set it to the path, but Laiev's one does it the other way around, so it sets it to the path first, and if local player isn't the one you want, it sets it to "" instead

Ok tnx.

But about the whole string table desync voodoo stuff when strings are used for first time? What does that mean?


Is it this:

function foo takes nothing returns nothing
     local string s = null
 
     if GetLocalPlayer() == some_player then
         set s = "string not yet in string table" // ooops desync?
         call AddSpecialEffect(s, x, y)
     endif
endfunction

 

[Komaqtion]

Well, it's only with local player stuff, nothing to worry too much about...


And I don't really know why it happens, or when :S XD

 

[Accname]

when a string is used for the first time it creates a handle and is saved.
and when any player got a different number of handles then others do it will desync.

if Komaqtion's trigger the string used for the special effect (given the case that this special effect string hasnt been used in the game already) is only set for the local player and thus creates its handle only for the local player.
in Laiev's trigger the string and its handle is created for all players but for all but the local player the string is overwritten with "".

 

[Sonic]

so which idea is what I need, can you say me?
