(jassHelped mod) Operator Overloading

03-25-2007, 09:54 AM

I'm new to this jass helper thing, I've been normal jassing for a long time, and I have some C++ background so it's really just an awesome merger of both languages O_o!

Anyways, I'm having trouble with operator overloading. For some reason (I'm sticking as close to the example as I feel safe with) my overloading doesn't work. -Take a looksy:

JASS:

struct PointMath
 real x
 real y
 integer nu

 method PolarProjection takes real dist, real ang returns nothing
  set .nu = 1
  set .x = .x + dist * Cos(ang)
  set .y = .y + dist * Sin(ang)
 endmethod

 method OffsetPoint takes real dx, real dy returns nothing
  set .nu = 1
  set .x = .x + dx
  set .y = .y + dy
 endmethod

 method operator[] takes real dist, real ang returns real
  return PolarProjection(dist, ang)
 endmethod

 method operator[]= takes real dx, dy returns nothing
  return OffsetPoint(dx, dy)
 endfunction
endstruct

Compiling error: "Not a valid indentifier name!" (Shows for both marked lines)

Thanks for the help. -Root.

blu_da_noob	method operator[]= takes real dx, real dy returns nothing Edit: oh, both lines... For the [] operator, it can only take one arguement I'm guessing, unless the syntax allows stuff like call BJDebugMsg(R2S(point[3,4])) Oh yeah, and polar projection doesn't return anything, but your [] operator needs to return a real. Mm. I don't know exactly what syntax limitations there are.

Vexorian	Yes, [] should only get one argument and return something, but the correct syntax error would be that. Are you sure you are using the latest JassHelper?

Blackroot	Dled it 4 days ago. -Even with corrected syntax it won't compile: Code: method operator[] takes integer whocares returns real return 100. endmethod

JASS:


struct PointMath
 real x
 real y
 integer nu

 method PolarProjection takes real dist, real ang returns nothing
  set .nu = 1
  set .x = .x + dist * Cos(ang)
  set .y = .y + dist * Sin(ang)
 endmethod

 method OffsetPoint takes real dx, real dy returns nothing
  set .nu = 1
  set .x = .x + dx
  set .y = .y + dy
 endmethod

 method operator[] takes integer whocares returns real
  return 100.
 endmethod

 method operator[]= takes real dx, real dy returns nothing
     call .OffsetPoint(dx, dy) //notice the .
 endmethod
endstruct

Compiles correctly in jasshelper 0.9.7.1

downloading 4 days ago <- But from the jasshelper thread and not from newgen pack?

Blackroot	I had the newgen version, I dled the single version from your sig and unzipped it in the folder, it still won't compile. -Edit I was apparantly under the impression that WEHelper and the jass new gen pack are connected somehow - Moved grimore into the correct place and it compiles now. Sorry -,-
