SyntaxBomb - Indie Coders

Hi,

DruggedBunny added a few operator overloads to Openb3d but they won't compile. The message is:
Compile Error: Syntax error - expecting '('.
So does anyone know how this works in NG? Here's a testing sample:
' operators.bmx

Local m1:TMesh=New TMesh
Local m2:TMesh=New TMesh
End

Type TMesh

' Operator overloading in bmx-ng allows adding/subtracting meshes,
' eg. "mesh3 = mesh1 + mesh2" to produce new mesh with CSG operations

Const CSG_SUBTRACT:Int = 0 ' Method 0 subtracts mesh2 from mesh1
Const CSG_ADD:Int = 1 ' Method 1 adds meshes
Const CSG_INTERSECT:Int = 2 ' Method 2 intersects meshes

Function MeshCSG:TMesh( m1:TMesh,m2:TMesh,method_no:Int=1 )

End Function
?bmxng
Method Operator+:TMesh(add_mesh:TMesh)
Return MeshCSG(Self, add_mesh, CSG_ADD)
End Method

Method Operator-:TMesh(add_mesh:TMesh)
Return MeshCSG(Self, add_mesh, CSG_SUBTRACT)
End Method
?
End Type


Are you using the latest version of NG?

Ah, no on Windows I'm using NG 0.77, that must be it. Cheers GW.

Yeah, operator overloads were added about Nov 2016 to bcc, which means any release older than v0.87 doesn't support them. I got it working using the latest NG.

Btw, to use them the syntax is:
Local tube:TMesh=CreateCylinder(32)
Local tube2:TMesh=CreateCylinder(32)

Local csg:TMesh=tube+tube2
'Local csg2:TMesh=MeshCSG(tube,tube2,1) ' 1=add
