Code-It-Yourself! Role Playing Game Part #1 

lol thats a big compliment, thanks Jordan!

Happy little coredumps.

@@javidx9 from your isometric demo I’m making a game like open ttd

@@samuelhulme8347 What's status 3 mounts later ?

@@crusaderanimation6967 very not at all, doing something completely different now

Are setters/getters rreeally necessary?

I've always seen getters and setters as a way of allowing the programmer to have control over variable access in the future, if they so choose. You may not care right now if other classes can directly access your player's position, but what if in the future you want to be able to log where the player is on the map for debugging purposes? It's a lot easier to put that in your setter function as opposed to having to track down all of the different pieces of code that interact with your public variable.

In my opinion, you can make class members public in managed languages like c# or java, but with unmanaged languages like c and c++ you NEED getters and setters.

You can control access to the attribute with or without accessor methods(getters/setters). You can have a public/private variable in your class or you can have public/private accessor methods. The advantage of accessor methods is that you can change a property back and forth between being computed and not being computed without changing anything outside the class. If you are 100% certain you won't need to do this, there's no real benefit to them(you're probably wrong if you are 100% certain of this). IMHO: This is one of the things that C# got right(and I'm a Microsoft hater) because it uses the same syntax for accessing a variable with a getter/setter as it does for accessing a variable without a getter/setter. This allows you to switch back and forth between computed attributes and non-computed attributes without having to worry about affecting code outside the class definition.

@@oliverzhang9004 Interesting, I normally see the opposite. Direct variable access in C(++) and getters/setters in Java and C#.

@p3rcio I hear from boomers that there was a time in the before times where internet didn't exist and people had to do this.

Thanks Sedit, I hope people can tolerate the "not entirely from scratch" nature of the series, its just to big to do everything in fine detail, without getting too boring

Ahhh well, it is entirely from scratch, I guess they are just going to have to Watch all the rest of your videos if they missed some of the pieces ;)

lol thanks FallAngel!

Thanks Mathew!

Hi Lucas, thanks! I agree, it just goes to show how perceived simplicity is in reality far from simple, I hope it serves to show ambitious young programmers that it takes time and effort to do even basic games, and that they should not start with 3D MMORPGs.

beautifully said.

I do hope you've had a fruitful year of learning.

Same! I looove computing and coding but I have a hard time understanding it's process. I'm more into the Linguistic side instead of the Calculus and Physics. However, I'm not giving up either. May you have a good luck into gaining knowledge in such thing. Cheers!

a no bajar los brazos papa!!

@@jrg4ngst3r83 Thank you bro

The engine simply takes input and displays coloured squares :D What can be done with that is only limited by your imagination! Thanks, Its been a lot of work this one, so I'm pleased its being appreciated already.

Hey thanks Brandon, I agree with you, I think procedural generation is a fascinating topic, and I hope to explore it a little one day. Added to the list :)

HAHAHA How did I miss this the first time around

i actually came scrolling for this comment because I wanted to make sure someone else caught that. awesome.

Thanks Davis, no problem!

Thanks Salvador, but Mrs Javidx9 would kill me if it didn't :D

javidx9 keep up the awesome work man. Really loving what your doing here. I know you are going to grow as a channel. 😊

I am pleased Bart, thanks!

@@javidx9 me too

Dang, yeah - a missed opportunity :D

I'm not familiar with those extensions, but the code should be compatible with both ASCII and Unicode. Also, my code can be easily converted to non-unicode if its a real problem.

Thanks Almark! In the case of this RPG series its just a windows command prompt.

@@javidx9 Welcome, so you can utilize graphics in general without the need to code extra even in windows? I guess for the more adv graphics one would program in OpenGl.

They are simple graphics but yes - I have since developed a very similar second engine olcPixelGameEngine which uses proper full colour pixels. It is cross platform also, but uses a bit of OpenGL behind the scenes.

Agree

Hi Adrien, that's a really good question, and any answer I give will only upset somebody else, but here it is. I have nothing against "modern" tools like those you described, but I also don't feel I always need the additional protection or utility those devices offer. I use them when I feel it's necessary. In this instance, the project is manageable enough to not need them, so I can code more fluently - which admittedly is a highly personally subjective opinion. Additionally, I'm a bit old fashioned perhaps, I've used arrays and pointers for 25+ years, and as a result I'm instinctively aware of where and how I'm managing my memory, so the risk of problems arising (in my specific case) is minimal. I hope you receive this as an honest answer, and not an attempt to discredit using such approaches.

Expanding on this, I've observed on recent code bases that smart pointers are ignored for the "traditional" approach. If you're allocating heap memory, and are confident in memory management for the given context, then I don't see an issue in handling raw pointers. I'd personally use smart pointers, as they'd serve to benefit on scalable code bases, but for stuff like this I'd be tempted to use raw pointers myself.

I am totally fine with your answer, :) good luck for the futur of your channel

Hi Samuel, yes they do, Introduction to console game engine is a good place to start!

nice to hear that, thanks :)

Thanks Tomasz! As with most of my projects I only delete what I explicitly allocate, and in this case you are correct, the system will do this. But also, given I know the simplicity of my projects Im happy for all the resources to be loaded once and remain resident. I'll be examining level loading in some detail in 2019 which will take a very different approach than that shown in this simple example.

Hi Londerson! Almost, there is an SDL2 version in the works that should be fine for linux. I dont have a mac to test it with though. It should just be a drop in replacement for the header file

Tanx, for the tip. Your work is amazing! Do you have a big fan here.

Hi Samil, this in some situations can be considered an advantage yes, but there are faster data structures than map that can achieve similar goals. I think its just important to choose the most appropriate tool for the job.

Wow that took me back :D

Why did you mention that name?

What exactly has OO to do with this choice? C++ supports it pretty well and the advantages of C# over C++ lie eleswhere.

this is premier league

Because goal of this video is not teaching game development, the goal of this video is teach object oriented programming

Sedit T To be fair, he attacks everyone :V

Hi Salainen. It is, in certain implementations you can specify 0b000111 for example, but not all of them.

javidx9 Okay, thanks!

Hi Phil, I notice youve been watching the entire back catalogue? Thanks for that! Ill answer all your comments soon, but I can do this one quickly, the code it yourself frogger video talks about sprites.

Indeed, and very edumacational it has been ;-) I did watch that one but the sprite stuff must have passed me by, I'll try again. I wonder whether there's some room for encapsulating them as a class to hide the heavy lifting and allow for future optimisation without breaking current code…yet another argument for Object Oriented Coding ^_^

A console project or just empty project is fine

@@javidx9 Oh really? Fantastic, thank you!

It will be continued. There is a LOT of crossover and identical between these two projects, so my plan is to take the dynamic character movement, and use it with Jario for enemy control

Alright, glad to hear that. Keep up the good work!

Hey Avvv, You can do similar things in linux - I have linux versions of olcConsoleGameEngine and olcPixelGameEngine. The console version uses SDL though

Thanks for the reply. SDL is the usual in Linux systems most of the time.

Oh i find it!

Good stuff!

Hi Jarmachi, my videos do assume you know some of the basics first, such as program flow, variables, arrays and routines. After that I just try to present ideas that people could have some fun with. This video is quite advanced relative to many of my others. I hope that using the console helps bridge the giant leap form "hello world!" to full graphical APIs, allowing newcomers to understand the principles of why what they do - does what it does.

Thank you for a response and yes I have a solid grasp on theses concepts as I have just finished my C programming course in college and was looking for more advanced subjects.

Jarmachi Heya Jamachi, just wanted to say that even when you follow along with a tute like this you’ll probably start to have opinions about doing things differently. I find I learn a lot when That happens because my opinion drives me to understand the code and look up c++ reference, which is easier with very focussed problems :)

Yeah, thanks, ive had a rush of traffic this month and exceeded my bandwidth. It should reset on the 1st. Though i will be relaunching the website at that time, so it may be a bit buggy 😁

The console is too large for your screen, try halving fonth and fontw values in ConstructConsole function.

@@javidx9 it works on the debugger, but the .exe dosen't show any pixels except the blue ff box, why do i get only 2fps?

Did you download the images required? Debugger runs much much slower than release build.

I would pay to watch this lol

I have used SMFL, SDL, OpenGL, DirectX and even experimented with Vulkan, but in this instance, I'm using the console.

What is the point in console games, they can not be monetized? хД

Well its not about making money for me, I do it for the fun of doing it, and I use an environment that is really simple for others to use too. If you've just written a "hello world" program, and asking what else can I do in the console?, well the answer is anything! :D

C--

C++

@@javidx9 Thanks!

Which part are you referring too Beavis, perhaps I can help!

@@javidx9 20:25 is the part i dont follow it may be all clear to someone who knows your channel but you see im new to your channel so im kinda clueless at this point

@@Goregreet Yeah, I use a header file called olcConsoleGameEngine (and more recently olcPixelGameEngine) which makes drawing to the console (or screen) very simple and accessible. Some of my earlier videos talk about this file in some detail. On my channel I try to focus on the algorithms rather than a specific implementation, so people often go and take those and implement it their own way. All the header file does is get user input and draw to the screen, it has no built-in game specific functionality.

@@javidx9 What about at 31:55 you all of a sudden have a ton of code not mentioned in the video?

The video does mention it, this project starts off using the "simple platform game" video code. Regardless you can see all the code in the github of you need to check things out!

he said its like FF because its more story driven. The way you move around and attacks things is like the original Zelda game.

@@JustinK0 Yes, he explains that really guy after, lol. It was a joke.

The only videos Ive not released source for is the RPG series - I will, I just want to tidy it up first.

err, c++ actually

@@javidx9 ok I got confused with the ide sorry

You can see the cpp files at the start of the video, it doesnt say .java or .cs it says cpp which is c++

Err, actually yeah...

@@javidx9 Ah that's funny that I guessed it correctly :d Anyways, what I put it there was a bit harsh. I think not getting best-practices is better than getting bad-practices. I hope you'll consider following some tech news and adjust your skills based on that?

Thanks man. I work on embedded projects with hundreds of source files, often in ides that are far from good. Ive found Hungarian notation to be invaluable to programming fluidly. If i need to do some mass refactoring then i should have spent more time in the design phase. Having visible information, i believe, doesnt do any harm.

you didnt want to "code an RPG game yourself"? hahahah

Well clearly you're too smart for this channel! Good luck!

@@javidx9 yeah he is well too smart 😂😂
