Learning Game for C - "Rescue Rambo"

[Matty]

Greetings folks,

I started learning the C language under the tutelage of ChatGPT (I ask it for tutorial exercises and it provides them to me as I learn the language).

Here's a sample 'roguelike' game I made this morning (the C code). You'll need a compiler to create an executable and run it. The objective of the game is to find the hut with the prisoner in it before the time runs out and avoid the booby traps and the enemy soldiers wandering about.

So far I've been learning the basic things you can see above, plus a little about strings not shown here. I've had two or three lessons so far.

So far I've been learning the basic things you can see above, plus a little about strings not shown here. I've had two or three lessons so far.

from Matt.

What compiler / IDE are you using to run this?

[Matty]

MingGw64 with msys2 (gcc)

[Baggey]

MingGw64 with msys2 (gcc)

Sorry to sound nieve But is this going down the lines of creating the .exe to run

I loved the Rambo Series of games on the Speccy. But they were hard to play.

Kind Regards Baggey

[Matty]

Yeah - you have to compile it to an exe to run. It was more a learning exercise for C for me.

Would you be prepared to do a little tutorial off how you got it working to an .exe

Im still learning new stuff day to day 

I to am interested in C.

Kind Regards Baggey

This is what I did:

First go to ChatGPT and ask it what do I need to install to have a C compiler. It said Mingw64 and gave me a website.

I followed the website instructions on how to download and install the compiler. It's very clear and straightforward.

I then asked ChatGPT to give me some tutorial exercises on the basics of C starting as if I were a beginner, but with some programming knowledge.

I completed the tutorials.

I then decided to try something a little more complicated so came up with a design that used the skills I'd learned so far - structs, a little bit of pointers, scanf and printf, arrays, and a few other bits and pieces. RescueRambo was born.

Not sure what else I can say really.

About 20 years ago I used Kernighan and ritchie's Learninig C book, and got their quiz / answer book too. TBH, their quiz / answer book proved too much hassle....so I wrote my own Space Invaders game in a DOS terminal, it had levels and all that jazz! No ChatGPT back then!

[Dabzy]

Many moons ago, I found Hisoft-C for sale on eBay, for my Amstrad, so I bought it for a play, and aye...

Created before C was standardised, it was a frigging nightmare!

Swung my head around it eventually, it just didnt swing "C" as I know it, obviously due to my grey matter having learnt standard C and know in the most part what that expects!

All in all, even though it was a mare, I had fun with it!

If you want a basic tutorial on how to set up a build environment.
I've just added a tutorial on setting up a GCC/MinGW tool chain and information on the types build systems and code editors.
