I noticed, some lines in c++ wont translate into PB (Notably the ones containing GLfloat or f)
------------------
C++ Code
Code: Select all
gluPerspective(45.0f,(GLfloat)width/(GLfloat)height,0.1f,100.0f);
Code: Select all
gluPerspective_(45.0, width / height, 0.1, 100.0)
-----------------Also This:
C++ Code
PB Code
I clearly have the right number of parameters. Does this error have something to do with the variable type im using?

Those functions expect doubles as arguments, which PB doesn't have yet.

Don't know if this helps:
Code: Select all
Structure Double
Hi.l
Lo.l
EndStructure
Procedure MakeDouble(LONG.f, ADDRESS.l)
!FLD dword [ Esp ]
!MOV dword Eax, [ Esp + 4 ]
!FSTP qword [ Eax ]
EndProcedure
Procedure.f CatchDoubleReturn(*x.Double)
!MOV dword EAX,[ESP]
!FST qword [EAX]
!MOV dword EAX,[ESP]
!FLD qword [EAX]
EndProcedure
example of MakeDouble:
Code: Select all
Procedure.l iSEDDrawImage(Left.f, Top.f, Width.f, Height.f)
dLeft.Double
dTop.Double
dWidth.Double
dHeight.Double
MakeDouble(Left.f, @dLeft)
MakeDouble(Top.f, @dTop)
MakeDouble(Width.f, @dWidth)
MakeDouble(Height.f, @dHeight)
ProcedureReturn CallFunctionFast(FPDrawImage, dLeft\Hi, dLeft\Lo, dTop\Hi, dTop\Lo, dWidth\Hi, dWidth\Lo, dHeight\Hi, dHeight\Lo)
EndProcedure
pain in the ass, but it works great
