QUESTION
I am receiving data packets over UDP that I parse into structs and in a specific situation my data gets all messed up and I can't figure out what the problem might be. Let me give you an overview of what I am doing.
- UDP Receiver receives the data packet and passes it to a callback - size of the byte array at this stage is 1307 bytes which is the expected size for the packet
- The byte array is marshalled (is that the right term?) into a struct - size of the struct is now 1484 bytes (not sure if that is relevant)
In this example the data is send from the Formula 1 2020 game and the curious thing is that the first entry in the m_carTelemetryData array (see below) is always fine, the data is all sound, however every entry of the 22 after the first one is totally messed up with either 0 values, null values or completely outlandish values for all the different fields in the struct.
I tried several things already to pinpoint the issue but have now reached the end of my knowledge about the things I am dealing with here. My best guess is that something is going wrong when converting the data into a struct or something else is going on that causes a misalignment (?) of the data.
What I tried so far
- Changed my code from "magic marshalling" to manual reading the data byte-by-byte using
BinaryReader- no luck - Manually checked the data using
BitConverter.ToFoo(bytes, offset)- no luck - Yolo changed the
Packattribute assuming that's where I got wrong - no luck - Double-checked the documentation to make sure I got the data types right - I am fairly confident that I "translated" them correctly
- Banged my head against a wall - still no luck
My questions:
- Is there something obvious wrong with my code that I am simply not seeing?
- Side question: am I wrong in my assumption that the size of the struct should match the suze of the byte array it has been created from?
Here is the code for reference (if anything helpful is missing, please let me know):
Packet Header
...ANSWER
Answered 2020-Oct-03 at 13:13I just pasted your code into LinqPad and found a few problems, the CarTelemetryPacket2020 structure needed a pack clause. Also m_tyresSurfaceTemperature and m_tyresInnerTemperature should have been a byte. The following returns a size of 1307 as per the protocol specification, you're right that the sizes should have matched up and I don't see any other obvious problems with your code.
QUESTION
Title may be wildly incorrect for what I'm trying to work out.
I'm trying to interpret packets I am recieving from a racing game in a way that I understand, but I honestly don't really know what I'm looking at, or what to search to understand it. Information on the packets I am recieving here: https://forums.codemasters.com/topic/54423-f1%C2%AE-2020-udp-specification/?tab=comments#comment-532560
I'm using python to print the packets, here's a snippet of the output, which I don't understand how to interpret.

...ANSWER
Answered 2020-Jul-08 at 12:14The website you link to is describing the data format. All data represented as a series of 1's and 0's. A byte is a series of 8 1's and 0's. However, just because you have a series of bytes doesn't mean you know how to interpret them. Do they represent a character? An integer? Can that integer be negative? All of that is defined by whoever crafted the data in the first place.
The type descriptions you see at the top are telling you how to actually interpret that series of 1's and 0's. When you see "unit8", that is an "unsigned integer that is 8 bits (1 byte) long". In other words, a positive number between 0 and 255. An "int8" on the other hand is an "8-bit integer", or a number that can be positive or negative (so the range is -128 to 127). The same basic idea applies to the *16 and *64 variants, just with 16 bits or 64 bits. A float represent a floating point number (a number with a fractional part, such as 1.2345), generally 4 bytes long. Additionally, you need to know the order to interpret the bytes within a word (left-to-right or right-to-left). This is referred to as the endianness, and every computer architecture has a native endianness (big-endian or little-endian).
Given all of that, you can interpret the PacketHeader. The easiest way is probably to use the struct package in Python. Details can be found here:
https://docs.python.org/3/library/struct.html
As a proof of concept, the following will interpret the first 24 bytes:

Ratiorg got statues of different sizes as a present from CodeMaster for his birthday, each statue having an non-negative integer size. Since he likes to make things perfect, he wants to arrange them from smallest to largest so that each statue will be bigger than the previous one exactly by 1. He may need some additional statues to be able to accomplish that. Help him figure out the minimum number of additional statues needed.

You have used sort function to sort the array in increasing order
QUESTION
I am currently working on my own display for an F1 steering wheel. F1 2019 (by codemasters) sends data through UDP. This data is stored in a byte array.
I am having some issues decoding the array being returned. The problem is that I get a lot of information back, but I don't know what to do with it. I will run you through what I have tried.
I am connecting to the game through port 20777 (standard port for the game):
...ANSWER
Answered 2020-Feb-16 at 10:06Okay so what I have found (Thanks to Jeremy) is that I need to get a structure out of the byte array. I followed these examples: Example1 Example2
So Codemasters (Makers of F1 2019) are sending a byte array with all the information needed. They have converted structs in to the byte array. These structs contain all the information which the game sends out. So the thing that needs to happen is converting the byte array back to structs. Keep in mind that the structlayout from Codemasters need to stay the same, Else you won't get the right information in the right variable.

QUESTION
Working on some Javascript challenges on Code Signal and I'm having an issue solving this:
Ratiorg got statues of different sizes as a present from CodeMaster for his birthday, each statue having an non-negative integer size. Since he likes to make things perfect, he wants to arrange them from smallest to largest so that each statue will be bigger than the previous one exactly by 1. He may need some additional statues to be able to accomplish that. Help him figure out the minimum number of additional statues needed. Example For statues = [6, 2, 3, 8], the output should be makeArrayConsecutive2(statues) = 3. Ratiorg needs statues of sizes 4, 5 and 7.
My approach:
- Sort the array smallest to largest
- Create counter variable to store number of missing numbers
- Iterate through array
- Subtract [i + 1] element from [i] element
- If it equals 1, numbers are consecutive, if not the numbers are not consecutive (increment counter variable)
- Return counter variable
Here is my code:

Answered 2019-Oct-23 at 02:12I'd approach it by building the target array which goes from the min+1 to the max-1 of the input by ones, excluding members of the input.....
