Please refer to the Adobe website, which is not described here.

1 C ++ code 1.1 interface functions

// Input as3_val test (void * data, as3_val ARGs) as a parameter in as3 Array {// create an array int array_size = 3; int array_c [array_size]; array_c [0] = 1; array_c [1] = 2; array_c [2] = 3; // obtain as3 array as3_val asarray = NULL from the parameter; as3_arrayvalue (ARGs, "as3valtype", & asarray); // obtain the push method of array as3_val push_function = as3_gets (asarray, "push "); // call the preceding Method for (INT I = 0; I <array_size; ++ I) {// You must create an array object and then The ray object is pushed to the result array !!! As3_val prior = as3_array ("inttype", array_c [I]); as3_call (push_function, asarray, int_to_push); as3_release (int_to_push);} reverse (push_function); Return asarray ;}

1.2 encapsulation and exposure

int main(){    AS3_Val testFun = AS3_Function(NULL, test);    AS3_Val _API = AS3_Object("test:AS3ValType", testFun);    AS3_Release(testFun);    AS3_LibInit(_API);    return 0;}  

2. use alchemy to compile C ++ into SWC

g++ test.cpp -swc -O3 -o test.swc

This process is slow.

3 as3 code

Package {import cmodule. a. clibinit; import flash. display. sprite; public class Test2 extends sprite {Private Static Var Lib: Object = NULL; Public Function Test2 (): void {var Loader: clibinit = new clibinit (); var Lib: object = loader. init (); var oldarray: array = new array (); // call the C ++ function var array: array = Lib. test (oldarray); For (var I: Int = 0; I <array. length; ++ I) {trace (array [I]) ;}}}

4. Run the as3 Program

Add the test. SWC generated above to the as3 project and add the path. Then run. My results in Flash buider are as follows:

123 [SWF] test2.swf-after decompression, It is 1,574,377 bytes [unload SWF] test2.swf
