No, Google translate works fine, you just haven't specified what you need to implement in script. You just mentioned:
6 minutes ago, toanpham6001 said:my value is "123" and offset is 0x10
but you haven't specified what script needs to do. Search for "123"? Then apply offset? How is this related to tagged pointers?
Again, either describe what script needs to implement with text or show it with video.

how would i script it?
Script what? Where is description of what needs to be implemented? Is it searching, is it editing, is it something else? If describing with text is too hard, at least show what script needs to do with a video.

Yes, conversions from/to tagged pointer can be implemented in script. The code to add tag to pointer can be found in this post:
Need help in script. I don't know if it's possible to do it automatically (#298r5x2m)And removing tag from tagged pointer can be implemented like the following:
local ADDRESS_MASK = ~(0xFF << 56) local function removeTag(pointer) return pointer & ADDRESS_MASK end

This is tagged pointer. There is no problem with it. You misunderstood the post from other topic, you shouldn't edit top byte of the pointer. You only need to remove it for navigating to the address in memory editor tab. For example, value of the pointer at address 0x754799F000 from the video is 0xB4000076B220F9F0, remove "B4" from it and leading zeros to get pointed address 0x76B220F9F0, then go to this address in memory editor tab and region label will be shown.

my top byte is already 0 what should i do?
Since you have already created separate topic for your question, provide the details there. Include region log, address of the value and the value itself.

Lua also allows to implement custom iterators to be used with generic "for", so one can implement traversal from 0 that way and use it like ipairs/pairs functions:
-- Modified function from http://lua-users.org/wiki/IteratorsTutorial function ipairs0(t) local function iterator(t, i) i = i + 1 local v = t[i] if v ~= nil then return i, v else return nil end end return iterator, t, -1 end -- Usage example for i, v in ipairs0(t) do print(string.format("[%d] = %s", i, v)) end

Could you perhaps provide an example function for print table starting at index zero*?
It's not more complicated than to print table elements starting from key 1. Looks more like the question is about how to print table elements at all. In the most basic case to print elements with integer keys starting from 0 and without printing contents of any nested tables it's enough to have one loop:
local t = {[0] = 0, 1, 2, 3} print("{") local index = 0 local element = nil while true do element = t[index] if element == nil then break end local representation = string.format(" [%d] = %s", index, element) -- implement custom type-dependent converion of value to string if needed, this one uses default conversion, i.e. string "1" and number 1 will result in the same output print(representation) index = index + 1 end print("}")

It's for readability.
For readability of the code or the output with table representation? If for the latter, one can simply create custom function to print table contents.
35 minutes ago, nok1a said:There are no regular arrays in Lua, only tables that are associative arrays and can be used to implement many different data structures. Tables in Lua don't have starting element by themselves, but length operator and functions from "table" library operate only on part of table with consecutive integer keys starting from 1. Your interpretation is wrong, because tables don't have defined order of traversal, it's implementation-specific. In fact official Lua doesn't include table contents in it's default procedure to convert table to string. So instead of relying on default table to string conversion in GG implementation of Lua, implement custom function that will perform conversion the way you need.

Note that metatable-based solution suggested above doesn't work as expected in all cases when key used in indexing access or indexing assignment exists in table, because "__index" and "__newindex" events are used only when key is not present in table. Though, XEKEX is right that it's not a good practice to have 0-based arrays in Lua. What is your use case for that and why 1-based arrays don't suffice?

Hmm, i don't exactly understand why string.format over string concatenation, could you perhaps explain?
Because string concatenation produces new string and there are multiple usages of it in the code.
29 minutes ago, nok1a said:I applied it like this to the script, This is ok?
Mostly yes, but format strings don't need to be passed as parameters in this case and instead of separate call to format address, do it in the same one.

in which case it may make sense to go with lookup table
This is misunderstanding from my side. Table-only solution isn't an option for this case, because of requirement to have structure number in name. So solutions can be only function-based (table may be used in the function, but there is no gain from it in this case), but there is indeed some room for performance improvement in my example above - by avoiding string concatenation and using "string.format" instead.

Do you mind if i use your example in the script? I would attach link to this threat as i did with the range function.
Feel free to do that. And there is no need for any credits in this case, but you can do however you prefer.
16 minutes ago, nok1a said:But i do question, if i write it in a separate function the function will be called for each loop. Will this not slow speed down drastically?
No, it shouldn't, but if you have millions of iterations, then the difference between function and lookup table might become noticeable, in which case it may make sense to go with lookup table.
18 minutes ago, nok1a said:Is it appropriate like that?
Yes, looks correct.

It looks like you need not a table, but function that returns name for value according to two parameters: structure offset and structure count. Here is an example of such function:
function getNameForValue(structOffset, structCount) local name = "Structure (" .. structCount .. ")" if structOffset == 1 then name = name .. " :Unknown: " elseif structOffset == 2 then name = name .. " :Field offset: " elseif structOffset == 3 then name = name .. " :Field amount: " end return name end

What's the point of "auto-destruction" of the file that is executed, if it can be simply backed up before executing it?
There are no ways (without using server) to prevent script from being executed more than one time that couldn't be easily bypassed, but if you still need to have that for some reason, basic approach is to check presence of certain file and only continue execution if the file is not present and to create that file right after the check has been passed.

Sorry, the answers to the questions above are present in your video. In your locale comma is decimal separator and for your values the search range that I suggested above is too narrow.
Try the following search string: "1,19999~1,20001"

If i search with 1,2
,2 not found must one value
Could it be that you use incorrect decimal separator with respect to locale that you have selected in GG?
There can be 2 options of the decimal separator: dot (.) and comma (,) . Try with dot first, then with comma.

But if i search 1~2 is found
This is correct approach, use range search, but make the range smaller. For example, for 1.2 search for "1.199999999~1.200000001".

Ouw not far from the instruction
If very far away cant ?
This is limitation of particular variant of LDR instruction, it doesn't mean that it's not possible anyhow. But to be able to provide you reasonable answer, one needs to know what you want to achieve, why do you need to use LDR in the first place. So provide the following information (preferably in new topic):
- what you are working with (function(s) name, description and instructions that it contains);
- which modification you want to implement (for example, make the function return fixed value).0 -

if the address is not far I can but if the address is very far away, LDR can't do it what is this limit?
There are 12 bits in the instruction that are used for encoding offset from PC in bytes, so the limit is from -4095 to 4095.

Eaxmple ldr addres : B179DE28
and i want load addres: AFFDACA4
ldr cant doit i dont know why
As other have mentioned above, such case requires more than one instruction. At least 8 bytes are required: 4 for LDR instruction and 4 for your new address that needs to be placed somewhere not far from LDR instruction. For example:
Address | Instruction/Value 12345678 | LDR R0, [PC, #-4] 1234567C | 0xAFFDACA4

It can't be used, because it is a pseudo-instruction that requires more space than single instruction.
Description and examples of LDR pseudo-instruction are present in ARM documentation:
https://developer.arm.com/documentation/dui0802/b/A32-and-T32-Instructions/LDR-pseudo-instruction0 -
Just presence of two base64url-encoded parts separated by dot is not enough to conclude that string is JSON Web Token. In fact, your string isn't valid JWT as per step 4 of "Validating a JWT" section of RFC 7519 (https://www.rfc-editor.org/rfc/rfc7519#section-7.2).

And loading saved list with option to set values can't really be faster than setting values directly by definition, since loading list in this case includes setting values. Also what makes loading saved list significantly slower than directly setting values is not setting values part, it's everything that needs to be done before that: reading and parsing saved list file, populating saved list with items.
