Multi Player instance

[iamdl]

Hello can anyone show me an example of MPI?? THX!

 

[Chaosy]

Code as it was for one player only. Then you add an array to every single variable and use player id as index.

 

[sethmachine]

In some cases it might not be as straightforward as having a variable/array position for each player, e.g. there are some events which have to be binded to a single player (player unit events), and so you would need to loop over your total players and create a trigger for each one (but the condition/action could be the same).

Here's an example

    loop
        exitwhen i == TOTAL_PLAYERS
        set t = CreateTrigger()
        call TriggerRegisterPlayerChatEvent(t, Player(i), "-", false)
        call TriggerAddCondition(t, Condition(function main))
        set playerDatum[i].npcTrig = t
        call DisplayTimedTextToPlayer(Player(i), 0, 0, 15, "Are you a guy or a girl?  Type '-male' or '-female' to choose your gender!")
        set i = i + 1
    endloop

    endloop

Can you convert it in GUI? im not good in jass

Actually Chaosy gave the answer. Sethmashine only explained how to take care of adding events in special cases.

Use variable[array]. And use PlayerNumberOf(OwnerOf(YourUnit)) as index that you use in these [] brackets.

• Heal
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
  • Actions
    • Set TempInt = (Player number of (Owner of (Triggering unit)))
    • Set H_Target[TempInt] = (Target unit of ability being cast)
    • Set H_Time[TempInt] = 3.00

I used TempInt to make the trigger more readable. TempInt uses the player number of the triggering unit which is a number between 1-12.

• Heal Loop
  • Events
    • Time - Every 0.03 seconds of game time
  • Conditions
  • Actions
    • For each (Integer H_Loop) from 1 to 12, do (Actions)
      • Loop - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • H_Time[H_Loop] Greater than 0.00
          • Then - Actions
            • Set H_Time[H_Loop] = (H_Time[H_Loop] - 0.03)
            • Unit - Set life of H_Target[H_Loop] to ((Life of H_Target[H_Loop]) + 1.00)
          • Else - Actions

The 1 to 12 in the loop represents the amount of players in the game so I made this spell for 12 players.

I don't think that's true.

AFAIK the OP's question was

Hello can anyone show me an example of MPI?? THX!

Chaosy described the general approach to making something MPI, but didn't give an actual example, which is what my post did (a string event that works for all players). The only problem with my answer is that the OP does GUI and not (v)JASS, which was not mentioned in the OP.

 

[IcemanBo]

@sethmachine, hm yes right he wanted an example. But your example had not much to do with MPI. Your code is an example for usage of loops.

 

[chobibo]

Chill people, focus on the topic.

Whatever is needed to make something MPI. And it is an example of MPI. I use a global array for each player in the body of the loop, with i as the player id index.

set playerDatum[i].npcTrig = t

the problem with your example is that no GUI-er will ever need anything like that, because they dont have access to custom script within events block. So to this point, Chaosy's and Iceman's answers are valid and correct ones(Iceman's especially, he even showed what to use as index)

[sethmachine]

the problem with your example is that no GUI-er will ever need anything like that.

The OP didn't state in what format he/she needed until after my answer, only asking for an example. This doesn't invalidate the information I provided.

answers are valid and correct ones

My solution is just as valid. Chaosy described the general technique, but did not supply an actual example. My answer was supplementing that post, showing that it also can require loops over the total players (for player events). AFAIK registering events which require a player as an argument require this kind of looping, otherwise they can't be MPI.

In any case, all my code is MPI, otherwise my project couldn't run (its a multiplayer RPG). And that's an example of how it's done, which is what the OP asked. Note he/she didn't say it had to be in GUI, vJASS, JASS, etc. until after I posted my answer. I'm no psychic.

Hello can anyone show me an example of MPI?? THX!

 

[edo494]

yes, your answer is valid and working, but if someone is asking for example on MPI, chances are, he has no ideea what Jass is, therefore will have no idea how events work internally, therefore making your example kind of pointless in this case, because I dont think op cares about this at this point of time. He maybe wants to make some good spell, which would work for all players, and last time I checked there is Generic Unit Event - Unit Starts Effect of ability.

My point is that yours(as well as Arhowk's) example is a bit higher level for the user

 

[sethmachine]

The OP hasn't clarified what he/she needs to make MPI--we don't know if its a custom spell yet or a string chat event. It is a rather vague question, and hopefully the OP clarifies on his/her specific needs.

 

[Chaosy]

If this was some kind of competition I would understand your argument. "Yeah you didn't specify so I want a point for that" however this is about being helpful you can't just say like "Deal with it, you didn't specify"

Also to be realistic my explanation work in 9/10 cases and that one time it's likely something very specific that I wont even come up with on the spot.

Here's an example btw. http://www.hiveworkshop.com/forums/...ed-213880/?prev=search=MPI&r=20&d=list&page=2
