1. 游戏中常用的词：
金币，钱：Cash、PremiumCurrency、Gold, money
无CD: Cooldown
2. Git pull 强制覆盖本地文件
git fetch --all
git reset --hard origin/master
git pull
3. dump: Il2cppReflection::dumpClassFromObj((Il2CppObject*)attribute);
4.在lua中..是字符串连接操作符
5.装包：arg1[2] =mono_string_new_wrapper(cmd.data);
6. Android根据图片文件名获取它的资源ID 的两种方式 :
方式1：
public int getResource(String imageName){
Context ctx=getBaseContext();
int resId = getResources().getIdentifier(imageName, "drawable" , ctx.getPackageName());
return resId;
}
方式2：
public int getResourceByReflect(String imageName){
Class drawable = R.drawable.class;
Field field = null;
int r_id ;
try {
field = drawable.getField(imageName);
r_id = field.getInt(field.getName());
} catch (Exception e) {
r_id=R.drawable.b_nothing;
Log.e("ERROR", "PICTURE NOT FOUND！");
}
return r_id;
}
checkbox事件：
viewHolder.cb.setOnClickListener(new CompoundButton.OnClickListener() {
@Override
public void onClick(View v) {
if (commodityInfo.isOwned()) {
boolean flag = commodityInfo.isOpen();
if (flag == true) {
viewHolder.cb.setChecked(true);
NativeUtils.nativeProcessCheat(commodityInfo.getNativeId(), 0, 1);
commodityInfo.setOpen(false);
}else{
viewHolder.cb.setChecked(false);
NativeUtils.nativeProcessCheat(commodityInfo.getNativeId(), 0, 0);
commodityInfo.setOpen(true);
}
} else {
viewHolder.cb.setChecked(false);
commodityInfo.setOpen(false);
GoodsManager.Buy(commodityInfo.getCommodityId());
}
}
});
