我正在尝试使用 expreditor 将代码中的 value 从 2.0 修改为 1.0。方法“alterSkill”下的嵌套 if 语句

if (player2.hasSleepBonus()) {
advanceMultiplicator *= 2.0;}

我有一个别人写的实用程序

public static void instrumentDescribed(Class<?> instrumentingClass, CtClass ctToInstrument, String declaredMethod, String descriptor, String methodCall, String replace){
        try {
            ctToInstrument.getMethod(declaredMethod, descriptor).instrument(new ExprEditor(){
                public void edit(MethodCall m) throws CannotCompileException {
                    if (m.getMethodName().equals(methodCall)) {
                        m.replace(replace);
                        success = true;
                    }
                }
            });
            checkSuccess(0, instrumentingClass, ctToInstrument, declaredMethod, methodCall);
        } catch (CannotCompileException | NotFoundException e) {
            //e.printStackTrace();
            checkSuccess(0, instrumentingClass, ctToInstrument, declaredMethod, methodCall);
            logger.severe(e.getMessage());
        }
    }

我的代码：

if (reduceSleepBonus) {
    Util.setReason("Change sleep powder from 2x to 1.0x");
    replace = "advanceMultiplicator *= 1.0;" +
              "$_ = $proceed($$);";
    Util.instrumentDescribed(thisClass, ctSkill, "alterSkill", desc4, "hasSleepBonus", replace);
    }

我的程序说它已成功实施。但是我怀疑它只是将AdvanceMultiplicator 设置为1.0 而没有将2.0 修改为1.0。我在程序中测试过，确认hasSleepBonus()为真时技能加倍。

if (reduceSleepBonus) {
    Util.setReason("Change sleep powder from 2.0 to 1.0");
    replace = "if($proceed($$)){ advanceMultiplicator *= 1.0; }" +
              "$_ = false;";
    Util.instrumentDescribed(thisClass, ctSkill, "alterSkill", desc4, "hasSleepBonus", replace);
    }
