This is a mui shield system, it's like in the game halo.

You are able to add shield points to any unit which work like additional life...

if the unit is attacked its shield loses hp but not the unit itself as long as the shield has hp left.
the shield can regenerate hp.

You can give a shield the following stats:
  • hp value
  • reg per second
  • no attack time till the shield regenerates (0 is constant reg)
  • a factor the damage the shield gets is multiplied with
  • the color of the remaining shieldpoints
  • a boolean whether the shield is destroyed when reaching 0 hp
  • a boolean to show or hide the shields bar
  • the duration the shield lasts (0 is a not timed shield)

functions to change nearly all of these values ingame are included (look at the documentation in the code)

with that it's possible to create powerfull shields^^

it's in vJass so it needs JNGP to work...

have fun^^
Update v.2.0: well,well after some points criticized by TriggerHappy a new update to make him actually "happy" :D
fixed the not destroyed timers, added a adjustable global for the interval, replaced a periodic trigger with a timer and fixed a bug

Update v.3.0: well Anachron has wrote nearly half of the comments here because of a bad size formula so with the help of Frunck I added a new one...
may you be satisfied now :D
In addition the shields can be timed now and they create an effect on the unit they protect

// The_Witcher's Shield System
//
// This is an easy to use shield system.
// it allows you to add shield points to a unit
// the shield works like in the game halo:
// the attacked unit doesn't receive any dmg, the shield gets it
// when the shield is down the unit is damaged
// the shield can reload constantly or after some seconds of not beeing attacked
//
// to give a unit a shield just use (if duration is 0 the shield will stay without a time limit)
//
//  call AddShield( towhichunit, hitpoints, RegPerSec, TimeTillReg,  damage factor, colorcode, destroy when shieldhp = 0, show the bar, Duration  )
//                    unit         real       real        real         real           string       boolean                  boolean       real
//                                                                                                                  
// you can check whether a unit has already a shield with (it will return a boolean)
//  UnitHasShield( yourunit)
//                  unit
//
// to implement this system, just copy this trigger in your map
// it requires jngp to be edited/saved
//
// To get rid of a shield just use
//   call DestroyShield( which unit's)
//                         unit
//
// to show or hide the shield bar use
//   call ShowShield( WhichUnits, Show? )
//                      unit     boolean
//
// to get information about an existing shield use:
//    HP:           GetShieldHp(  unit  )
//    maxHP:        GetShieldMaxHp(  unit  )
//    percentHP:    GetShieldHpPercent(  unit  )
//    regeneration: GetShieldReg(  unit  ) 
//    TimeTillReg:  GetShieldTimeTillReg(  unit  )
//    DamageFactor: GetShieldDamageFactor(  unit  )
//
// to change the values of an existing shield use:
//    HP:           SetShieldHp(  unit, NewValue  )
//    maxHP:        SetShieldMaxHp(  unit, NewValue  )
//    percentHP:    SetShieldHpPercent(  unit, NewValue  )
//    regeneration: SetShieldReg(  unit, NewValue  )
//    TimeTillReg:  SetShieldTimeTillReg(  unit, NewValue  )
//    DamageFactor: SetShieldDamageFactor(  unit, NewValue  )

Yo man I've downloaded your system while it was still GUI ('bout a year ago), and it insipired me to create damage systems based on your own also in GUI for my map Guild Arena: the BattleChasers, cuz i'm not that good at Jass, but now I see that you have a Jass version of system so i'll be sure to check it out and maybe implement it into some of the next updates my map.


All in all

+Rep for the old system and inspiration that it gave me
+5 to rating


TNX alot :thumbs_up:

oh yeah this is the spell you made that i'm using already. good work. it's a favorite of mine. although i'm pretty lazy i didn't add the graphics yet. i have good excuse, though...i had needed time to find the correct graphics model. i'll have to say, though...i found the shield bar didn't work...not that i care.

Hey cool system man,

Quick question about tweaking it a bit, I thought it would be cool if instead of deactivating the shield (like in the demo map), once you use the spell again, it grants another shield. So in other words, the shield would stack.

I mean that could be done just by increasing the absorbed damage I suppose, but I want it to actually look like 2 shields, so that means there would have to be another private variable, lets just call it sfx2.

So could you post an example script of this stacking shield tweak? Letting it stack if cast twice, and it would be cool if you could code it so that the two shields die one by one, like as each shield dies the respective sfx is destroyed, as opposed to simultaneously dying.

It should. Instead of just saying "it doesn't work" you could at least quote the error message you got, or screenshot the error dialogue, or identify the line that is causing errors, or upload the map with the trigger disabled, or.... The error dialog on save is actually, you know, trying to help you figure out what the problem is.

Oh I'm sorry I'll show you the lines later. And actually even tried saving the spell's map itself and worldeditor still won't let me.

Either you're using some old version of the WE/something like WEX or JNGP... or your install is borked. It saves just fine for me without any errors. Is your game updated?

My game is updated but I just noticed I can't also sabe damage detection for me so I think my install is borked. Well, thank you for helping me and sorry for saying that this spell doesn't work.
