• Instead of using the ForGroup function to figure out the number of units, you can keep track of the number of units dead and alive by yourself using a couple of integers.
• ResumeTimer -> TimerStart because it's faster
• Instead of using those StringHash functions, you can use constant integers, or as the others suggested, keys.
• CheckOwner can be shortened to 2 lines. You just need to return the conditions of the if statement. (return playerId == 10 or playerId == 11 or playerId == 12)

 

[Almia]

can you post the triggers sir?

 

[Mr_Bean]

Done. Code uploaded.

 

[Almia]

i thought you put the gui version

 

[Mr_Bean]

It's written in vJASS, but you can obviously use GUI actions (custom scripts).

 

[Almia]

ohh okay ill test it tomorrow

 

[Peacehagen]

I recommend this system, very easy to use (and i have 0 jass knowledge) and works perfectly. All other i have tried have had an issue that some units did not respawn but this solved it

5/5

 

[KnnO]

This function moves group units to <enum> then moves them back to <g> function EnumerateGroup which is nonsense, you can use:

private function Inc takes nothing returns nothing
      set /*a temp private global integer*/ count = count + 1
endfunction

function EnumerateGroup takes group g returns integer
      call ForGroup(g,function Inc)
      retun count
endfunction

But I am not sure If you are using it that way because it is faster or something...are you? or because you don't want an extra function and an extra variable? IDK

Everything else is fine I guess

 

[Mr_Bean]

Update:
Uploaded version 1.0b:
- Fixed creep counting as per KnnO's suggestion.
- Added map name, description and author for the demp map.

@KnnO: Thanks man! I guess I'm just too used to using FirstOfGroup loops in spells. Much appreciated.

 

[KnnO]

Well I saw your user title so I think you are better than me with coding

No problem Mr_Bean987, I am glad I could help!

@Mr_Bean987, First of all nice API you got there Alright lets get down to business. Instead of using hashtables, i suggest you use a struct and store the handle id of the unit on its respective timer when it dies. If you still insist on using hashtables, then i suggest you use the variable type

key

and make it constant; this is rather than using stringhash.

Hope i helped, peace

 

[-Kobas-]

Yeah key will generate random unique number and using is as constant will increase "security" even more.

StringHash is something we do in GUI, use integers in jass, it's faster.

 

[Mr_Bean]

Can you please give me an example of how I should use key...

If I were to use structs, would I create a new instance for each creep? Is this more efficient than hashtables?

/*          ======================
            Respawn System - v1.1
            ======================
            
        Coded by:       Mr_Bean ([email protected])
        
    Introduction:
    -------------
This system was originally requested by Peacehagen for his map Rise of the Corruptor ORPG.
He recommended that I upload it because it would help people, which I hope it does!
I added some new features to the system and made it as user-friendly as possible.
This system only works for units that are on the map as soon as the game starts.
Feel free to contact me if something is not clear, or if you find bugs.

    Installation:
    -------------
> Copy this trigger.
> Copy the "TimerUtils" trigger (if you don't have it already).
> Configure the "Configurables" section in this trigger as desired.

    Available Functions:
    --------------------
> RespawnAllCreeps()
    - Immediately respawns all dead creeps.
    - Does not affect countdown timer.

> RespawnAllCreepsForPlayer(player whichPlayer)
    - Immediately respawns all dead creeps for a specified player.
    - Does not affect countdown timer.

> PauseRespawnSystem(real howLong)
    - If all creeps respawn together, you can use this to pause the system.
    - The parameter is how long it is paused for. Use any negative number to pause it forever (until you resume again). Using 0 means no pause.
    - Can only use if RESPAWN_TOGETHER = true.

> ResumeRespawnSystem()
    - This will resume the system.
    - Only works if you used PauseRespawnSystem with a negative number (like PauseRespawnSystem(-1)).
    - Can only use if RESPAWN_TOGETHER = true.
    
> ResetRespawnSystem()
    - This will pause the system and reset the countdown.
    - Needs to be unpaused with ResumeRespawnSystem().
    - Can only use if RESPAWN_TOGETHER = true.
    
> RestartRespawnSystem()
    - This will reset the respawn countdown.
    - Will not pause the system.
    - Can only use if RESPAWN_TOGETHER = true.

> GetAliveCreeps()
    - Returns how many creeps are alive.
    
> GetDeadCreeps()
    - Returns how many creeps are dead.
    
> GetTotalCreeps()
    - Returns how many creeps there are in total.

There is no need for struct, btw, I must suggest that you make timer library optional, so you can use this system even without it.
I say this because I myself code in that way to minimize number of external libraries I use.

For example Table library is really awesome but using it in your map only because of 1 spell is ridiculous, where it can be replaced with indexing or single hash, but when you speak about 10 spells 1 table will certainly become more powerful than 10 hashtables.

 

[Mr_Bean]

But then how can I respawn a specific creep when it dies without attaching its handle id to a timer?

 

[-Kobas-]

Then you create timers yourself

 

[Mr_Bean]

But how do I attach data to a timer? Sorry, I've gotten so used to TimerUtils

 

[-Kobas-]

You don't all you need is timer handle
then when it expires you detect it again.
local integer id = GetHandleId(GetExpiredTimer())

Original

    private function Increment takes nothing returns nothing
        set tempInt = tempInt + 1
    endfunction
    
    private function EnumerateGroup takes group g returns integer
        set tempInt = 0
        call ForGroup(g, function Increment)
        return tempInt
    endfunction

Loop is more efficient than call a function for every unit!

Optimized

    private function EnumerateGroup takes group g returns integer
        local unit picked
        set tempInt = 0
        loop
            set picked = FirstOfGroup(g)
            exitwhen picked == null
            call GroupRemoveUnit(g, picked)
            set tempInt = tempInt + 1
        endloop
        return tempInt
    endfunction

Ohh! lol then:

    globals
        private group TempGroup = CreateGroup()
    endglobals

    private function EnumerateGroup takes group g returns integer
        local unit picked
        set TempGroup = g
        set tempInt = 0
        loop
            set picked = FirstOfGroup(TempGroup)
            exitwhen picked == null
            call GroupRemoveUnit(TempGroup, picked)
            set tempInt = tempInt + 1
        endloop
        return tempInt
    endfunction

 

[Mr_Bean]

But then the group is left empty :O

 

[FRENGERS]

Update it
Go Go Mr. Bean I like your system @[email protected] Really neat :3 :3 And cute :3 :3

Oh, and,
How about you add the heroes respawn?? It's basicaly use the time * heroes level....

//TESH.alwaysfold=0 <---- This line is covered in blue when I try to save my map after copying your trigger. It worked some days ago. But then suddenly this happens everytime I save.

Edit: I am using Sharpcraft, as I also did when I first implemented your system. It just suddenly stopped working even without making any difference from the time it worked. I am green on this one.

 

[verstefyren]

Never mind, I deleted Sharpcraft and redownloaded it. Works fine.
