MY GOAL
I wanna put my custom STRUCTURE definition and it's methods in a plugin dll, and then use them in my project.
QUESTION
Functions works well, but when I using the structure SED said the structure was a undeclared identifier.
NEED HELP
How can I define a STRUCTURE in a plugin dll and use it in SED?
I HAVE DONE THIS
I learned from the acknex manual and found it only says how to write functions into a dll and call them in .c files at chapter "plugin SDK", follow that I created a dll with one function only use ENGINE OBJECT TYPE. I named this dll "DllTemplate.dll" and copy it to acknex_plugins folder. It works.
I put my structure and methods in the dll source like followed code, Compile and update the acknex_plugins folder files.
/************************************************
*
*THE "DllTemplate.dll" SOURCE
*Name:DllTemplate.cpp
*Node:Those code compile the DllTemplate.dll file
*Using:VS2008 C++
*
*************************************************/
#include "stdafx.h"
#define WIN32_LEAN_AND_MEAN // Exclude rarely-used stuff from Windows headers
#include <windows.h>
#include <stdlib.h>
#include <malloc.h>
#include <memory.h>
#include <tchar.h>
#include <math.h.>
// engine specific header file
#define DLL_USE // always define before including adll.h
#include "adll.h"
/************************************************
*MY STRUCTURE DEFINE HERE
*************************************************/
typedef struct DllStruct
{
BMAP *m_pBmap;
}DllStruct;
BOOL APIENTRY DllMain(
HANDLE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved)
{
engine_bind();
return TRUE;
}
/************************************************
*FIRST FUNCTION, IT WORKS WELL
*************************************************/
DLLFUNC void PanelBgChange(PANEL* pPanel, BMAP *pBmap)
{
pPanel->bmap = pBmap;
}
/************************************************
*MY STRUCTURE TEST METHOD
*************************************************/
DLLFUNC DllStruct* CreateDllStruct( BMAP *pBmap)
{
DllStruct *DllStructInst = new DllStruct;
DllStructInst->m_pBmap = pBmap;
return DllStructInst;
}
And then I write these in SED to test the dll.
/************************************************
*
*THE DLL TEST PROGRAM SOURCE
*Name:DllTest.c
*Node:Those code do some tests of the DllTemplate.dll file
*Using:SED
*
*************************************************/
#include<acknex.h>
BMAP *pDllBg = "images\btn_jump.jpg";
BMAP *pBgImg = "images\btn_empty.jpg";
//The test result shower. The panel.bmap shows the different states.
PANEL *pDllTestPanel =
{
pos_x = 100;
pos_y = 100;
flags = VISIBLE;
digits(0,0,"Press A",*,0,0);
}
//Declare the functions defined in dll
void PanelBgChange(PANEL* pPanel, BMAP *pBmap);
DllStruct* CreateDllStruct( BMAP *pBmap);
//main function
function main()
{
level_load("");
wait(2);
//create a dll structure instance
DllStruct *pDllStructInst= CreateDllStruct(pBgImg);
pDllTestPanel.bmap = pDllStructInst.m_pBmap;
while(1)
{
if(key_a)
{
PanelBgChange(pDllTestPanel, pDllBg);
}
else
{
PanelBgChange(pDllTestPanel, pBgImg);
}
wait(1);
}
}
SED told me ERROR:
'DllStruct' undeclared identifier.
<DllStruct* CreateDllStruct( BMAP *pBmap);>.
So I have to put this code in front of main function.
/************************************************
*
*STRUCTURE DEFINITION
*Node:This is a part of DllTest.c
*Using:SED
*
*************************************************/
typedef struct DllStruct
{
BMAP *m_pBmap;
}DllStruct;
This time everything is Ok.
But I wanna put this STRUCTURE DEFINITION in the dll.
How can I do that?
Thanks to read.
