This helped me so much! I want to make this game called "Hello World!" It is about this flower who comes out of his seed and says "Hello World!" He then goes out into the world to find love. He does, and the lady flowers and the main flower live happy and create a new flower, but then the 2 flowers die, but a new one comes out of its seer and says: "Hello World!"

Two little tips from me: 1. Make sure you have the GB libraries in the directory/upper directory to use the Intellicens (you can find them in gbdk\include\*). 2. Make sure the batch file points to the correct 'main.c'. Sunst you get the message that the 'main.o' was not found. Because then the compiler can't compile correctly.

[@GamingMonsters]

There is an easier way to get intellisense working and get rid of those wiggly lines, check this videos description for the link to the video to solve that

[@oscwavcommentaccount]

I have 'main.c' and 'make.bat' in the same folder, but i get the message that 'main.o' wasn't found.

Bro same. I plan on my first game being small, but called "Hello World". It's short game about a flower who is all by its self. It then goes out into the world to find love. And at the end of the game he meets a flower and the 2 flowers die, but a new one is born and says: "Hello world."

The way to fix it is to save the files. That's it. When your on the page just press crtl-s and it should save, make sure to save both and then run the file. turns out Visual studio doesn't auto save when you run a file.

[@danielsequeira1608]

I got the same thing and it's apparently just that you haven't set a value for vs code to look for the include files. You can find the option to change it in the settings.json and type in the directory, just that instead of normal slash (ex: c:/Users) you use 2 back slashes (ex: c:\\Users) Note: this only happens when you download a C/C++ Compiler extension, so if you have trouble finding settings.json, try going to the description of the extension

There is hundreds of languages that provide all the features C# has without being centered around a corporation that tries to make money out of everything they can. Can you write an operating system in C#, you probably could but it would be pain; could you write a web browser in C#, you probably could but it would be pain. The language requires a virtual machine (CLR) to execute anything, that might be ok for your business applications that involve writting 10 lines of code but when you need to write something bigger running in real-time you need language like C, C++, D or Rust.

[@adrulb]

​@@bjarnestronstrup9122 First of all, why are you talking about the CLR? This is about the LANGUAGE not it's runtime/compiler. The official C# compiler is open source and licensed under Apache 2.0 Additionally .NET 5 is being worked on and it is going to have an option for Ahead-Of-Time-compilation. Why is writing a web browser in C# a pain? Have you tried it or are you just hating on C#? Writing an OS in C# is possible and people have done it.

[@bjarnestronstrup9122]

@@adrulb You probably don't understand that it's not about compilation or C# it self, it's about garbage collection. C# was designed as a garbage collected language and will most likely stay garbage collected until it dies. When you write software with real-time requirements then you want to take advantage of the CPU cache as much as possible because accessing RAM directly can be hundreds of times slower. Garbage collector needs to check random memory locations at random points in time, both of which can cripple your cache usage. kzbin.info/www/bejne/jXWsnKSGaa-Voac watch this when you have some spare time on your hands.

Figured it out. You need to add “/path/to/gbdk/include/“ (your actual path, not exactly that) to your includePath. Hard to fully explain here but if you don’t understand a bit of googling should help you figure it out.

Hey, when running the make.bat file the second line returns an error : C:\Users\Usuario\Documents\GameBoyLearningCoding\gbdk\lib/small/asxxxx/gb/cr.: cannot open. But cr. doesn't even exists in the folder.

[@GamingMonsters]

I’m not sure what this error is referring too sorry. You could try eliminating a few common problems 1) move gbdk to c:\gbdk as some people have had issues with it in some folders 2) check you are an admin on your pc?

Main.o gets created by the first line of the bat file

what OS are you using? when I try to run .\make.bat in the terminal, it tells me its not a valid application for this OS platform

[@GamingMonsters]

Have you double triple checked you have actually saved the make.bat file from the file>save menu 99.9% of the time others with this exact same issue find this is the problem as vscode does not make it obvious it hasn’t automatically saved the file

I have a problem compiling the code that I made. I also deleted the code from the previous episode but nothing seems to help. the terminal says "undocumented I/O error". How do I fix it?

[@GamingMonsters]

Can you upload your code somewhere or email to [e-mail] and I’ll take a look

[@Decimated_By_A_Train]

I keep getting the error "main.c:2: error:gb.h: undocumented I/O error" after I run the batch file, I cant find any resources to help me either. EDIT: I removed the gb.h header and it compiled fine, but I'm guessing that'll pose a problem later on so what should I do?

[@GamingMonsters]

Where did you install gbdk folder to and where are you writing your code (the paths to both would help me diagnose)

[@Decimated_By_A_Train]

GamingMonsters I have gbdk in the root and my code file on the desktop. Im going to try copying the Include file from gbdk into my code file and updating the includePath to see if that works

you definitely shouldn't need to move the gbdk file, can you zip the code up and email to [e-mail]?

[@joshuajefford3323]

Im getting 2 issues on make.bat, “error ***** parse error at end of of input” and “cant find main.o”

Can this be done on Linux, too? Also, isn't using void main in a hosted environment undefined behavior?

[@GamingMonsters]

pretty sure it will all work on linux but I dont have any experience setting it up myself so you will have to give it a go. I suspect GBDK's version of C is a little less strict than others

[@James2210]

@@GamingMonsters It might with a little work. The binary distribution is really old (only 32-bit) and the C source has some issues that need to be fixed. I know GBZ80 fairly well now, so I might just go ahead with my original idea and write it in assembly.

If you already know assembly I definitely would do that github.com/rednex/rgbds seems the most modern way to do that

I have been looking at learning assembly to write things for the gameboy. But I find it really hard to find the tools and such tbh... I am just laughing at the fact people have made this toolkit with c that's fantastic and makes me want to cheat 😂

[@icedo1013]

I taught myself some very rudimentary assembly code when I got into ACE for Pokemon Blue (I even wrote a small function!), and in my experience, it was definitely parsable if you took the time to understand the processes and how the chips actually operate.

I've never written anything in C, though I often right code in C#, & the two seem very similar.

[@GamingMonsters]

I’m the same in terms of c# being my daily language. The biggest difference is having to be very careful about memory and the size of variables as c will not stop you making silly mistakes (like trying to put 10 items into an array you sized to 3 items or putting an int16 value into an int8 so you need to be a lot more careful when coding

Ok ill try 1) Are you files saved on your c:\ drive or another drive, if they arent on C:\ try moving them there 2) What version of windows are you using? 3) Have you definately saved make.bat? Some people using VScode think they have but they havent really. Open windows explorer and check the file is really there 4) Are you an administrator on your pc? Some users have had issues on locked down school or work pcs where they are not allowed to run .bat files
