jass help - 1st time

[exge]

ok, i finally know the basics of jass ... yay .. so can some1 tell me of a spell which cannot be done in gui at all .. cos now i feel all can be done in gui too ...

yea .. and mayb some tutorials for jass-spells ... thanks all

 

[dadads]

A spell that can't be done in GUI?
Yes, try creating a multi-instancable dash-type spell (try make a Time Walk like in dota, or Greater Bash like in dota). Make sure that the sliding is smooth and does not look "broken".

What I mean by multi-instancable is that the spell would work such that the spell will run when any unit that has the skill uses it, and that it should still work correctly even when two units are using the same spell at the same time. Oh, and btw do not use global variables coz it would make the spell not multi-instancable.

 

[exge]

thanks dadads .. but this is my 1st time making a jass spell .. lol so i need at least a tutorial or a example to refer to ..

 

[Arkan]

Daelin has a knockback example in one of his JASS tutorials, it uses Kattana's local vars system which I never got to work myself, however I managed to get it working by using vexorian's CScache system.

 

[emjlr3]

or you might want to try my Dash spell tutorial ^^

 

[dadads]

lol, I actually learned how to create slides with JASS by studying his (the guy above me) Spiritbreaker map.

Once you can create a dash-type spell, you can try make a keyboard-controlled racing game, a "Snake" game, or whatever.

ok so i got somehthing like this .... but the unit moves more like blinking ... see for yourself

function Trig_Dash_Conditions takes nothing returns boolean
    if ( not ( GetSpellAbilityId() == 'A000' ) ) then
        return false
    endif
    return true
endfunction

function Trig_Dash_Actions takes nothing returns nothing

    local unit caster = GetSpellAbilityUnit()
    local location targetloc = GetSpellTargetLoc()
    local location casterloc = GetUnitLoc(caster)
    
    loop

        set casterloc = GetUnitLoc(caster)
        call SetUnitPositionLoc(caster, PolarProjectionBJ(casterloc, 10.00, AngleBetweenPoints(casterloc, targetloc)))
        call PolledWait( 0.0001 )
        
        exitwhen DistanceBetweenPoints(casterloc, targetloc) <= 50
        endloop
endfunction

i think we need to improve the jass tag ..

i dont understand the bold part, i think it means the red part

 

[corvusHaunt]

function LocalVars takes nothing returns gamecache
    // Replace InitGameCache("jasslocalvars.w3v") with a global variable!!
    set udg_myCache=InitGameCacheBJ( "jasslocalvars.w3v" )
    return InitGameCache("jasslocalvars.w3v")
endfunction

Try this:

function LocalVars takes nothing returns gamecache
   if udg_myCache == null then
      call FlushGameCache ( InitGameCache ( "jasslocalvars.w3v" ) )
      set udg_myCache = InitGameCache ( "jasslocalvars.w3v" )
   endif
      return udg_myCache
endfunction

lol, I actually learned how to create slides with JASS by studying his (the guy above me) Spiritbreaker map.

Once you can create a dash-type spell, you can try make a keyboard-controlled racing game, a "Snake" game, or whatever.

hehe another one, I cant tell you how many ppl have told me they learned JASS looking at my dota spell maps heh

 

[dadads]

The reason why "set udg_myCache=InitGameCacheBJ( "jasslocalvars.w3v" )" won't compile might be that you forgot to create a global variable named "myCache".

That's the problem I encountered when using Kattana's local handle vars for the first time.

Go to the GUI variable editor, make a new variable called "myCache" (the udg_ prefix will be inserted automatically in the JASS script, but it won't appear in GUI - so don't put the udg_ prefix in GUI).

The variable "myCache" should be of type "game cache"

function LocalVars takes nothing returns gamecache
if udg_myCache == null then
call FlushGameCache ( InitGameCache ( "jasslocalvars.w3v" ) )
set udg_myCache = InitGameCache ( "jasslocalvars.w3v" )
endif
return udg_myCache
endfunction

This is also a good idea, much more improved

 

[exge]

i couldnt find your map ... so i was pretty much alone .... and using a system in my 1st spell .. didnt help much
EDIT: it still wont compile ..now the error is from my handle part ... which means the trigger is wrong ... can some1 help me take a look at my trigger

 

[exge]

err ... bump..

 

[phyrex1an]

Have you created a global variable named myCache?

 

[exge]

yes, even before i posted this thread lol

 

[phyrex1an]

function Dash_Move takes nothing returns nothing
   local timer t = GetExpiredTimer()
   local unit caster = GetHandleUnit(t, "caster")
   local location casterloc = GetHandleUnit(casterloc, "casterloc")
   local location targetloc = GetHandleUnit(targetloc, "targetloc")
   
   call SetUnitPositionLoc(caster, PolarProjectionBJ(casterloc, 50.00, AngleBetweenPoints(casterloc, targetloc)))
endfunction

Should be

function Dash_Move takes nothing returns nothing
   local timer t = GetExpiredTimer()
   local unit caster = GetHandleUnit(t, "caster")
   local location casterloc = GetHandleLocation(t, "casterloc")
   local location targetloc = GetHandleLocation(t, "targetloc")
   
   call SetUnitPositionLoc(caster, PolarProjectionBJ(casterloc, 50.00, AngleBetweenPoints(casterloc, targetloc)))

endfunction

And

function Trig_Dash_Actions takes nothing returns nothing

    local unit caster = GetSpellAbilityUnit()
    local location targetloc = GetSpellTargetLoc()
    local location casterloc = GetUnitLoc(caster)

    call SetHandleHandle(t, "caster", caster)
    call SetHandleHandle(casterloc, "casterloc", casterloc)
    call SetHandleHandle(targetloc, "targetloc", targetloc)
    
    call TimerStart(t, 0.035, true, function Dash_Move)
    call TriggerSleepAction(0.5)
    call FlushHandleLocals(t)




//======================================================================  =====
//=========================Clear the leaks===================================
//======================================================================  =====

    call RemoveLocation(targetloc)
    call RemoveLocation(casterloc)
    set caster = null

endfunction

Should be

function Trig_Dash_Actions takes nothing returns nothing
    local timer t = CreateTimer()
    local unit caster = GetSpellAbilityUnit()
    local location targetloc = GetSpellTargetLoc()
    local location casterloc = GetUnitLoc(caster)

    call SetHandleHandle(t, "caster", caster)
    call SetHandleHandle(casterloc, "casterloc", casterloc)
    call SetHandleHandle(targetloc, "targetloc", targetloc)
    
    call TimerStart(t, 0.035, true, function Dash_Move)
    call TriggerSleepAction(0.5)
    call FlushHandleLocals(t)




//======================================================================  =====
//=========================Clear the leaks===================================
//======================================================================  =====

    call RemoveLocation(targetloc)
    call RemoveLocation(casterloc)
    call DestroyTimer(t)
    set t = null
    set caster = null

endfunction

And you must add this to your Handle Vars system (normaly you uses X and Y real values and not locations in jass)

function GetHandleLocation takes handle subject, string name returns location
    return GetStoredInteger(LocalVars(), I2S(H2I(subject)), name)
    return null
endfunction

Also, you have missed to null a lot of handle child variables in there.

 

[exge]

it still doesnt work, now the guy just moves too fast ... i cant even see it
you can see the map for yourself , he keeps going to the center of the map
