Simple programming example of interaction between ActionScript and C/C ++

If you don't want to talk about anything, go to the source code. For more information about alchemy, see the official documentation.

1.
Declare a header file myutil. h with the following content:

# Ifndef myutil_h

# Define myutil_h

# Include "as3.h"

Namespace myworld {

Class Io

{

Public:

Static as3_val _ bytearray_cls;

Static as3_val _ nsname;

Static as3_val _ clsname;

Static as3_val _ empty_array;

Public:

Static as3_val getbytearraycls ();

Static as3_val getemptyarrayobj ();

};

}

# Endif

2.
The implementation file of the header file myutil. H is as follows:

# Include "myutil. H"

Namespace myworld {

As3_val IO: _ nsname = NULL;

As3_val IO: _ clsname = NULL;

As3_val IO: _ bytearray_cls = NULL;

As3_val IO: _ empty_array = NULL;

 

As3_val IO: getbytearraycls ()

{

If (_ bytearray_cls = NULL)

{

/*

* Assign a value to _ bytearray_cls to obtain flash. utils. bytearray. skip this step. If you do not know it, contact us privately.

*/

}

Return _ bytearray_cls;

}

 

As3_val IO: getemptyarrayobj ()

{

If (_ empty_array = NULL ){

/*

* Assign a value to _ empty_array to obtain flash. utils. bytearray. skip this step. If you do not know it, contact us privately.

*/

}

Return _ empty_array;

}

}

3.
Declare a header file myarray. h with the following content:

# Ifndef myarray_h

# Define myarray_h

Int writeheader (char * Header, int length );

# Endif

4.
The implementation file of the header file myarray. h. The content is as follows:

# Include "myarray. H"

# Include <string. h>

Int writeheader (char * Header, int length ){

Char * STR = "helloworld ";

Int size = strlen (STR );

Int I = 0;

For (I = 0; I <size; I ++ ){

* (Header + I) = * (STR + I );

}

Return size;

}

5.
The main. cpp function is implemented as follows:

# Include "myarray. H"

# Include "myarray. cpp"

# Include "myutil. H"

# Include "myutil. cpp"

# Include "as3.h"

# Include <stdio. h>

As3_val geteaacheader (void * data, as3_val ARGs)

{

Char cppflvheader [128];

Int cppflvheaderlen = writeheader (cppflvheader, 128 );

As3_val asflvheader = as3_new (myworld: IO: getbytearraycls (), myworld: IO: getemptyarrayobj ());

Char * tmpcppflvheader = reinterpret_cast <char *> (cppflvheader );

As3_bytearray_writebytes (asflvheader, static_cast <void *> (tmpcppflvheader), cppflvheaderlen );

Return asflvheader;

}

Int main (){

As3_val geteaacheaderfun = as3_function (null, geteaacheader );

As3_val _ API = as3_object ("geteaacheader: as3valtype", geteaacheaderfun );

As3_release (geteaacheaderfun );

As3_libinit (_ API );

Return 0;

}

6.
Put these files in the same directory and compile them with alchemy. The command is as follows:

Alb-on; G ++ main. cpp-O3-wall-SWC-O main. SWC; Alb-off

7.
Call in flex Builder as follows:

ImportCmodule. awu. clibinit;

ImportFlash. utils. bytearray;

Public
Static const_ Lib_init: cmodule. Main. clibinit =NewCmodule. Main. clibinit ();

Public static constCmoduleapi: * = _ lib_init.init ();

Public
Static FunctionGeteaacheader (): bytearray {

ReturnCmoduleapi. geteaacheader ();

}
