Question

我有一个swf文件，我反编译了它。我得到fla和文件，我试图运行这些文件，但我得到这些错误

1180: Call to a possibly undefined method li8.
1180: Call to a possibly undefined method li8.
1180: Call to a possibly undefined method li8.
1180: Call to a possibly undefined method si32.
1180: Call to a possibly undefined method li8.
1180: Call to a possibly undefined method li8.
1180: Call to a possibly undefined method li8.
1180: Call to a possibly undefined method li8.
1180: Call to a possibly undefined method si8.

并且这些函数必须在avm2.intrinsics.memory这个包中但不存在我试图更改这个软件包附带的SDK版本AIR 3.5,3.6,3.7和其他一些但不是它们作为这些函数。有什么问题

检查您是否使用ASC2.0编译器。

快速内存操作码是ASC2.0编译器的一部分，不属于AIR SDK的一部分。根据您使用的IDE，avm2.intrinsics.memory操作码方法可能会在代码编辑器上显示unresolved error，但它可以使用ASC2.0编译器构建。

以下代码使用AIR SDK 27中的intelliJ IDEA进行了测试。

package {

import flash.display.Sprite;

import avm2.intrinsics.memory.sf64;
import avm2.intrinsics.memory.lf64;

import flash.system.ApplicationDomain;
import flash.utils.ByteArray;
import flash.utils.Endian;

public class FastMemTest extends Sprite {
  public function FastMemTest() {
    var ba:ByteArray = new ByteArray();
    ba.length = ApplicationDomain.MIN_DOMAIN_MEMORY_LENGTH;
    ba.endian = Endian.LITTLE_ENDIAN;
    ApplicationDomain.currentDomain.domainMemory = ba;

    const addr:int = 0xf0;
    const value:int = 1234;
    sf64(1234, value);
    trace(value.toString(16), ':', lf64(value));
  }
}
}

跟踪输出：
