First Shot at a "Dash" Spell

> 2 locations, 4 points.

But if you did that, wouldn't you have to convert the coordinates to locations first with the native Location function?

Oh yeh, I forgot that function uses locations and not reals. Well I think the formula for getting the distance from 2 sets of coordiantes is

SquareRoot((x2 - x) * (x2 - x) + (y2 - y) * (y2 - y))

> I opened it up and when I look at a JASS trigger, there's no highlighting and there's no Syntax Checker.

No idea. Have you checked the menus that you said you can see? Everything enabled? How about posting a screenshot of what you do see?

As for the location, you might be able to use this:

native Location                 takes real x, real y returns location

Anything supposed to be checked?

I forgot, you have to get the TESH for New Gen to get the good syntax checking and highlighting. (That is, after all, what it stands for: Trigger Editor Syntax Highlighting.) Here:

Here's the current script. It still doesn't work. It's crashing.

 

[Waaaaagh]

If NewGen is crashing on you, I can't even begin to imagine what your problem is...

 

[WarLuvr3393]

How do I use the syntax checker in NewGen?

 

[Waaaaagh]

... Just make sure it is installed in the folder that NewGen comes with. Just follow the instructions really....


EDIT: nvm. I just save, cause NewGen has never crashed on me, and it does a good job of finding the errors.

 

[WarLuvr3393]

Still crashing...any help?

 

[elmstfreddie]

call TriggerAddAction( gg_trg_Flamewalk, function FW_Cast )

function FW_Cast takes nothing returns nothing
  //Local Variables
    local timer t = CreateTimer()
    local unit caster = <b>GetTriggerUnit()</b>
            
  //Set Variables
    call SetHandleHandle(t, &quot;caster&quot;, caster)

Explain to me how that is supposed to work

(I intended to bold foney things but that didn't work )

Check up the posts a little more, I posted the updated the version of my script. Please check that out.

Here ya go :

globals
 constant integer FW_Rawcode = 'A002'
endglobals

function FW_Check takes nothing returns boolean
 return GetSpellAbilityId() == FW_Rawcode
endfunction

function FW takes nothing returns nothing
 local timer t = GetExpiredTimer()
 local unit caster = GetHandleUnit(t, "caster")
 local location target = GetSpellTargetLoc()
 local real x = GetUnitX(caster)
 local real y = GetUnitY(caster)
 local real x2 = GetLocationX(target)
 local real y2 = GetLocationY(target)
 local real angle = 3.14159/180.0 * Atan2(y2 - y, x2 - x)
 local real distance = SquareRoot((x2 - x) * (x2 - x) + (y2 - y) * (y2 - y))

    if distance != 0 then
       call SetUnitPosition(caster, x + 30.0 * Cos(angle * 3.14159/180.0), y + 10.0 * Sin(angle * 3.14159/180.0))
    else
       call PauseUnit(caster, false)
       call ResetUnitAnimation(caster)
    endif     
    
    set caster = null
    call RemoveLocation(target)
    set target = null
//  set t = null **I dont know if you would have to set t to null here...   
endfunction

function FW_Cast takes nothing returns nothing
 local timer t = CreateTimer()
 local unit caster = GetTriggerUnit()
            
    call SetHandleHandle(t, "caster", caster)       
    call SetUnitAnimation(caster, "attack")
    call PauseUnit(caster, true)
    call TimerStart(t, 0.05, true, function FW)
    call TriggerSleepAction(2.0)
    call FlushHandleLocals(t)
    call DestroyTimer(t)
    
    set t = null
    set caster = null
endfunction
    
//===========================================================================
function InitTrig_Flamewalk takes nothing returns nothing
 local integer i = 0
 
    set gg_trg_Flamewalk = CreateTrigger()

Should work.

I'm getting: "Expected End of Line" in many places.

I'm getting: "Expected End of Line" in many places.

If you're using the JASS NEWGEN PACK it should compile fine, I just tested it. If you dont wanna use it then just go back to using constant function for getting the abilityID and it'll work in regular WE too.

 

[WarLuvr3393]

OMG! This JASS stuff is really starting to make me quit........ugh........whenever I try to load this up on NewGen, it gives me an error and when warcraft iii opens, it goes to the main menu.

What's the best way to learn JASS? This is getting annoying.

Haha, you better get on those tutorials! Lucky for you there are a TON on these forums. I would suggest the GUI to JASS tutorials to get started.

 

[Sooda]

In post #23 uncheck mark from "Disable vJASS Syntax". That should enable vJASS syntax check. When you go into main menu while testing your map in New Gen then it means there are syntax errors (What means vJASS syntax check didn' t ran at all. I have encountered same problem many time. Usually helps to save map twice. Then with other save syntax check kicks in.).
Right now it seems that your vJASS syntax check is disabled and you have to uncheck that mark to enable it.

 

[emjlr3]

ever heard of my Dash tutorial???

yea...search it up

 

[WarLuvr3393]

Eh, but you used the caster system and it's so hard to understand it with your "Table" stuff.

 

[emjlr3]

i didnt use the caster system, i used a cache system, which is required for it to work well and MUI, until vJASS came along
