Spell Request: Charm (complicated one)

[Avaleirra]

Hi I need help with a spell and I have no idea how to make it.


I wish to create a charm with a 10 second cast time. The spell needs a castbar and must be interupted when the caster moves, sleeps, gets stunned, paused, or dies. The charm is not a hero ability and can only target ancient, enemy, neutral, invulnerable, structure.

Needs to be MUI and MPI.


I'm assuming this requires JASS or vJASS. I have newgen so it's all good .



I'll give rep and credits since this is sorta urgent .



Thanks
Avaleirra

cant you just give charm a casting time?

if not base it off of channel, detect when a unit finishes channeling a spell (with the targets on whatever you want to target)

The only problem with this is the castbar, but i don't see if it's that necessary? If none of your other spells actually use a castbar, then, this is a waste of time. Why don't you make a spell with a 10 second casting time, and then create floating text that would go 10, 9, 8, 7...etc... . To make it MUI i suppose you'll need hashtables or some sort of a timer, i'm still quite inexperienced with it, but some people here are pretty good with them ^^

Also, its quite laggy, at least I heard. There's this casting bar system somewhere in this forum, I think it has something to do with strings... And it'll cause lag.

Just use the ordinary charm and give it a 10 seconds casting time, and use this Casting Bar System.

Use a single target dummy spell.
Hide the unit.
Create a new unit using the same unit-type.
Add a no target channel spell to the dummy unit.
Add a 10 seconds expiration timer to the dummy unit. This will be your casting bar.
Detect if the dummy unit is interrupted & remove it & bring the original unit back.
Detect if the unit expires & change owner of the target unit & bring the original unit back.

You will need an array index system to make this MUI (it's possible to do in GUI by just using an array and an integer variable to count and reset the array integer).

 

[Avaleirra]

I have already attempted using a casting time. Here's what went wrong.


-couldn't interuppt it by walking away
-stuns, sleeps, pauses didn't stop it
-even if the caster died it continued



The castbar worked fine though and there was no lag.

@Bogrim
I think the MUI thing is beyond my level of triggering spells.

@Bogrim
I think the MUI thing is beyond my level of triggering spells.

Then let's go with something more simple:

• Mind Control
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Mind Control
  • Actions
    • Custom Script: local unit u
    • Custom Script: local integer i
    • If Array_Index = 1000 Then Set Array_Index = 1 Else Set Array_Index = (Array_Index + 1)
    • Set Temp_Integer = Array_Index
    • Custom Script: set i = udg_Array_Index
    • Set Temp_Location = Position of (Casting unit)
    • Unit - Hide (Casting Unit)
    • Unit - Create 1 (Unit of unit-type (Casting unit)) at Temp_Location facing (Facing angle of (Casting unit))
    • Custom Script: call RemoveLocation( udg_Temp_Location )
    • Unit - Add a 10.10 seconds Generic expiration timer to last created unit
    • Custom Script: set u = GetLastCreatedUnit()
    • Unit - Add (Channel dummy ability) to (Last Created Unit)
    • Unit - Order (Last Created Unit) to Orc Shadow Hunter - Big Bad Voodoo
    • For each (Integer Custom_Integer[Temp_Integer]) from 1 to 20, do (Actions)
      • Loop - Actions
        • Wait 0.5 seconds
        • Custom Script: set udg_Temp_Unit = u
        • Custom Script: set udg_Temp_Integer = i
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • (Current order of Temp_Unit) Not equal to bigbadvoodoo
          • Then - Actions
            • Set Temp_Location = (Position of Temp_Unit)
            • Unit - Remove Temp_Unit from the game
            • Unit - Unhide (Casting unit)
            • Unit - Move (Casting unit) instantly to Temp_Location
            • Custom Script: call RemoveLocation( udg_Temp_Location )
            • Skip remaining actions
          • Else - Actions
    • Unit - Change ownership of (Target unit of ability being cast) to (Owner of (Casting unit)) and Change color
    • Set Temp_Location = (Position of Temp_Unit)
    • Unit - Remove Temp_Unit from the game
    • Unit - Unhide (Casting unit)
    • Unit - Move (Casting unit) instantly to Temp_Location
    • Custom Script: call RemoveLocation( udg_Temp_Location )
    • Custom Script: set u = null

I wrote this out of my head so it probably doesn't match the WE's text completely, but I hope it gives you an idea of how this trigger would work.

I guess you are looking for something similar to DotA's Sand King's Epicenter, in terms of casting? You'll have to use it as a channeling spell instead of casting time. Make a spell with 10 seconds channeling time and 0 casting time, with no effects. Then use trigger to detect the finish channeling (I think its finish casting) event and do whatever you need in the actions. Thats without the floating text/casting bar part though. You'll need another trigger for that I guess.

 

[Dirac]

Do this:

A unit begins casting an ability

Add unit to CastGroup

-----------

A unit stops casting an ability

Remove unit from castgroup


then check if the caster is still in castgroup
EDIT: Forgot to mention, this method works PERFECTLY for me, and has no bugs since a unit cant cast 2 abilities at the same time

 

[Xienoph]

Don't you also need:

A unit finishes casting an ability.

Charm the unit in castgroup

EDIT: nvm. Misunderstood your approach.

This.

Let me explain better.
The best way is to make 3 triggers. One for the casting bar, one to start it, and one to cancel it in the event the unit moves.
The casting bar trigger will also contain whats to be done after the unit is done with the 10 seconds cast time.

The first trigger will roughly do this:
event:
Every 0.05 seconds (or whatever low-ish value you want. The lower the more accurate, but also the more laggy)
Conds: somebooleanvar == true
actions:
increase an integer by 1
then increase the cast bar's length by 1/200th (note, your cast bar may not and will probably not have 200 ticks, what you'll want to do is every 10 ticks of that integer, increase bar by 1 tick (thats for a 20-ticks bar))
once the integer variable reaches 200, that means 10 seconds passed
enter actions to be perfomed here (Charm in your case, so you have to save the target unit and owner of casting unit in variables when the unit starts then use them here)

The second trigger:
event: unit starts the effect of an ability
conds: ability = charmwithcastingtime
action: set somebooleanvar = true (remember that condition in the first trigger?)

the last trigger:
event: unit stops channeling an ability
cond: ability being cast = charmwithcastingtime
action:
set somebooleanvar = false
set integervariable = 0 (the one you use to tick in first trigger)

now for this to be bug free, you need to make that charm a channeled ability with duration equal to10 + the time in the first trigger's event

(for example, i used Every 0.05 seconds of game time, that would mean a duration of 10.05 seconds)

One last thing, this isnt mpi nor mui. If you want it MPI, make every variable a 12-indexes array. If you want it MUI, you need to use jass to create a new timer every time a new index has to be used.

Is there a mana cost? Should it be spent at the beginning of channeling, or at the end?

What should happen if you start charming a target that is already being charmed, and the other spell finishes while yours is still casting?

[edit]

if not base it off of channel, detect when a unit finishes channeling a spell (with the targets on whatever you want to target)

Did it this way, with a ghettotastic casting bar.

Other concurrent casters will be ordered to stop when the target is successfully charmed. Requires a unit auto-indexer (map includes GUI-AIDS).
