Code-It-Yourself! Simple Tile Based Platform Game #1 

Your videos are what I have been looking for when it comes to tutorials. Thank you for making these!

I really enjoy the way you explain your coding approach to solving the game scenarios. Well done.

I went from developing in C to developing in C++ because of your fun and interesting videos

I've been looking for a good answer to collision detection for a few days now and I can't believe how almost perfect this advice was for my situation, much more simple to implement and just as robust in my situation as anything like minkowski differences and anything else etc. This video was a great help! Thanks :)

I love this channel so much. Bro, thanks. I have learned a lot with u videos. Love from brazil! Keep it up 💪

Thanks so much for making this, even if I don’t follow along in all these videos it gives me a good idea on how things are working together in the code

Awesome! Another javid video. Liked before seeing :) Thank you very much for these. Looking forward for more!

16:50 "not that impressive so far" I mean, I think its pretty damn impressive to get that much up and running with so few lines of code, and so elegantly. The olcGameEngine is pretty solid NGL. Orders of magnitude better than the engine I wrote in college to make a similar game concept for a final project where even getting this much of the game up and running would have been ~300+ lines of code (not including level design).

Your videos have helped me learn C++ so quickly. Thank you for the high quality content

Your channel should have much more views. I really enjoy your work. Cheers from Turkey!

Love your videos, even if I already know these things, I like to see your way of teaching them.

Fantastic videos you make, so clear and understandable!

You have no idea how helpful this is! I've done so much searching online for a simple yet effective way to implement collisions in 2d platformers only to come up with solutions with mediocre results. After so many pages of sketches and code the solution was to check the corners based on where the player was moving... Awesome!

buddy, I want to make a public acknowledgment to your work... you explain briefly, clearly and extremlly good. I have learned a lot from C++ programming just by watching your videos. Best thing of all, they're fun... greetings from Venezuela.

I use C and raylib and these tutorials are still very helpful, keep up the good work!

This is by far one of the best programming videos ive seen on YT. Totally OUTSTANDING!

Using the idea of your algorithm I created more accurate way to detect collisions in my game. Thanks a lot.

Thanks a LONG LONG INT number of millions for your fantastic videos! Keep them coming

this is good ! This is enjoyble ! That project is not difficult or easy. I am watching your videos. Lots of fun (all videos). And Code-It-Yourself!

I did indeed forget it was the console window. Classy.

Been learning alot from your videos brother. thanks a ton.

I really enjoyed the video. Thanks! It helped me a lot! (: hope there is the second part.

I am sad I found your channel so late, If I would know about it half year ago I could be completely somewhere else. Thanks for the good work!

"Take that visual studio code" Me: *Laughs in overtype extension*

Waiting for part 2 :) slopes and enemy could be a good topic

I would give you 10 thumbs up if I could! You showed in the intro the end result (which is always preferred), and you showed some awesome code. Thank you! Just a tip, maybe if you could spare the time, for your videos putting bookmarks is helpful. Great Work!

Very similar to the Collision detection I was using for the platformer I was Tinkering with Javid, Since many tutorials I see online suggest all sorts of stuff like checking every tile within specified vicinity etc .... Its nice to see someone else starting with the corners like I decided to do as well... I test the 4 corners, Then I test middle bottom +1 block in the Y axis to decide if the jump/falling Flag should be set or not.

I just found this channel, and I thought I knew stuff in coding... well I don't know anything, buy I will watch this video 20 more times, and try to code the same thing using this video, and watch past/future videos too.

Would love to see a code along with me video. Where you code something and record it in a way to where we can type what you are and you can explain each line as we type it out. would really help me a lot with memorization. Just a steady shot of the codieng screen no cuts while we code along you learn more that was then just going to the page you have posted copying it over and then reviewing what you have copyed while the video plays. to many cuts for me to type out the code like you do while your talking about it and you code fast so i keep haveing to pause to keep up lol. thanks for all the awasome videos!

The bearded and wise one! We need a follow up! :D

Dude you are the best !

Finally new video! I will really appreciate if you will do some polygon collision math :) thank you

great game , you are the best , please make more big great games

I'm retired and need something to keep my brain turning into mush so I decided to write a game for the Atari 7800. The game I picked was Apple Panic from 1981 that was on the Apple and the Atari 800. So far, on my own I've managed to built the screen using tiles, created my sprite, created a running sequence for left and right movement and I'm working on moving vertically. I've discovered a few of your routines by myself but your video is going to be a HUGE help in smoothing things out. I'm going to try to work your techniques into my code. Sadly, Atari 7800Basic is limited (I think because the end result will be 6502 code and hardware driven) but it does have floating point. I will have to keep coming back here for more help. Thank you very much for making this video and I will check for other video you've made. I wish I could send you a clip of what I've done so far. It represents about 4 weeks of work using a language I don't know on hardware I don't know but so far so good. Thanks again.....

Really wish 2d platformers were more popular on this channel i love working on them

The protag is you!!! Fantastic.

This jumping scheme with gravity effect with some control you put in out does Ghost N Goblins jumping that is for sure.

*Delivering a big thumbs up to help your self-esteem*

You are the nicest youtube programmer. Love the pace and atmosphere of your videos. Keep on the great work! You might want to try the Borland C++ Builder environment for these projects. It provides the Canvas object where you can draw shapes and bitmaps on the screen with a single line of code. It provides ready-made windows forms for you to work on. I always use it for quick projects. it would be perfect for these projects of yours, including anything in 3D. If you look on my channel on my latest videos, I posted a 3D engine I wrote in Borland C++ Builder.

Subscribed, you deserve my sub. However, i would like to see some OpenGL / D3D stuff in the future. Keep up the great work tho!

Well done. Thx for the video. Greetings

24:12 good math concept

So cool, it's definitely, "replayable!"

Great tutorial, I hope it will be an update for the PixelGameEngine.

Really interesting video! Any chance for part 2?

Amazing his canal.Parabéns!

Hi Javidx9! I just wanted to give a big thank you for your videos. They are amazingly informative and helpful. Many years ago I did a bit of programming but fell away from it after becoming more involved in systems administration. Now I'm getting back into it and find your style of instruction just my cup of tea. I've a huge fascination for roguelikes and mazes, 2D cRPGS, and procedural terrain/cave/overworld generation. A long time favorite game of mine has been Dwarf Fortress and any game in a similar style (nethack, ADOM, Caves of Qud, Cogmind, etc). As a player of pen and paper D&D I love the tables of stats that these games produce. What games, if any, are your favorites? I'm finding the Visual Studio 2017 IDE easy to use as a general text editor, but there is so much depth to it that I oftentimes find myself lost. For example, your recent solutions have shown several projects contained within. I'm not able to replicate this sort of container/structuring in my own solutions. I typically just make one solution and inside that the .cpp and .h files where need. Would you consider a tutorial on the IDE that could cover such things? I'm keen on learning how to best use the tools at hand and not just use them like notepad. Again, thank you for such quality videos and sharing your passion.

perfect movie

Hello, I really look forward to following along with your video. I checked out your code on github and I was hoping you'd be willing to briefly explain how to use this code? Do you only need the code from the main page, or do we need separate files or classes as well?

just started programming like this week. so far i have a box and a bear in the box that shoots lazers. was trying python now going to c++

I've been following your channel for a little while now. I think it's time to subscribe :]

Silly question - this video has #1 in the title. Was there ever a part 2? I think 2D platformers are a great topic, and would love to see more!

mine says the end of my switch loops curly bracket is a syntax error?? how come? edit:Turns out i needed a "break;" after the default to make it work. Thanks Dave.

Hey! I love your video on how to create a platformer game! It really teaches me alot on what I require! Just a quick question. you mentioned that you created an array to read in the alphabets. Am i able to use FileIO to read into it from a textfile and then do the same stuff for the rest of the video?

Hope this is ok to comment here but if anyone’s in need of music I’m looking to work on a project. Thanks for the upload!

Great video.

Have you got any basic videos on how to great a window / fundamentals of setting up? edit : like how you created the one lone coder console game engine?

Love the video, explains things very easily... But I don't quite get the font change, what does that do, I see no difference? Possibly it's a raster like pattern in the former font? That could be YT Compression artifacts though...

I really love the video and the simple approach to collisions. I'm implementing it in Lazarus/FPC wich is what i have and i'm used to (planning a small game for my kid). I wonder if the collision detection can work if the tile and the character hit-box are different sizes because all calculations are done in the unit-less space. Maybe if sprites are a multiple of the tiles? For example if the sprite is 2 "units" tall and 1 "unit" wide (I'm thinking in a small Jario / big Jario situation).

How do I run this program on a mac? I've been trying for hours to find answers ,but it seems it's only plug and play for windows.

I'm pretty new to all this have to say but one think that getting me is I'm spending so much time watching tutorials and trying my best to learn these things while not wanting to directly copy someones code while learning it. i watch your video along and am typing in the code as you do but then i see on the page you have posted that i could just copy and past the code over but that is lame its going to take forever for me to know coding enough to be able to just code something without looking up someone else formula. For now its fun i guess to follow along typing in the code getting familiar with what each line dos and then making my own art to put into the game so yeah I'm following someone else code but I'm putting my own spin on it with my art.

Hi Sir , i wanna ask you , about a specefic path to follow in order to be able to make a game in c++ like you do , because i always find out that i don't understand a lot of things because i skipped them in the learning curve ,tell me for example what should i learn first , Thanks in advance , this will help me a lot :)

Really great idea about doing a video on Super Mario👍🏻

Does anyone know if games like Geometry Dash or The Impossible Game are tile-based (do they use huge 2d arrays to represent entire levels)? Or are they made in a different way?

Trying to implement in Java, everything seems interpretation-able except collision left and up collision work fine right collision heads down and down collision heads right??? so frustrating :( using same collision If's but using a tick(up,down,left,right) and render(Graphics2D g) system also separated player and level logic into respective classes any idea what might be wrong can post code/project if needed - great vids btw

your coding all the fun stuff! l

Love your videos. I'd also appreciate if you could do a video talking more about game engines and perhaps how they work compared to your OlcGameEngine.. not sure how much of a viable topic that is, to be honest, just a suggestion (y)

If you have some trouble with the non pixel perfect (0.9f) approach (like I do), a simple workaround is to ignore the (bottom tile for x detection || right tile for y detection) if you're currently on a tile (no decimal position). Which leads to something like that: bool ignoreBottomTile = ((int)(player->getOldPosition().y) - player->getOldPosition().y == 0); Tile* nextTile = ignoreBottomTile ? nullptr : map->getTile(player->getPosition().x + 1.0f, player->getOldPosition().y + 1.0f); if(previousTile != nullptr && previousTile->isSolid() || nextTile != nullptr && nextTile->isSolid()){ misplacementCorrection()} It really is a psychorigid problem, but some may be... :s Anyway, keep the good work on those tutorials, they are awesome !

Hold up a sec - you're telling me all that time this was running on a command line?!

I don't understand why, but sometimes when Jario moves fast and the program starts to get laggy, then Jario is able to break the collision rules, for example he can get through walls. Is it an implementation problem? Notice that I've had to reduce the size and the resolution of the screen, in the original resolution 256X240 with size 4x4 the program opens up just a narrow black square. Thank you!

Another question what if I want use an image from another software such as Adobe Photoshop, Lightwave 3D or even Hitfilm Pro?

Sorry for the naive question, is your code compatible on UNIX systems? Love your videos!

It's super Jario! He's a... french electrician.

Awesome! Nintendo does not get ungry with you, yet!

Hey so I know c++ quite well as language but there is some syntax I don't understand that seems to be part of Visual Studio Code. For example: DWORD and L" ". Where does one learn about those?

Is this c++ or C# have to specifically make a game using visual studio 2017 and monogame and it has to be done in C#

Hmm I was thinking can you show how to go down pipes to get to secret areas?

i came to this one from the 3d graphics engine one and now i want to make a platformer with 3d graphics and physics like you would see from a company. T_T it's gonna be hard but someday.

How can I start to learn from your videos? I watched some videos but I dont really understand completely. Should I learn C++ first and then move to your videos later?

جاوید 👏👏👏

I really want to become a developer, please can someone help with. Where and how should i start,? i have basic knowledge of C++. Thank you

Even though I’m way too late, How do I include the olc into my program? I downloaded the old game engine in a zipped file but I don’t know how to include into the program. Thanks!

can you please give a link for download mario image u use please

Great tutorial, however I am having an issue with the program. Whenever I try to debug the program, it just creates a very small window with nothing on it, and the output says the program exited with a code of 0. How should I approach this?

Hi, I love your videos! I had a little issue. When I pass the parameters into the game.ConstructConsole(160,120,8,8) It gives me an error of screen and font size too large. The only work around this is by using 80,60,4,4 but that makes my window very small. How can I solve this?

help please am using this tutorial and downloaded all the files like have been said and typed the code identically to the tutorial but it keeps giving errors that certain codes like the GetKey codes are undefined what should i do i am so lost

genius

sorry i have a question , what engine is this? sdl, allegro? or something write from you on c++?

Am interested in making a game but know nothing of C++ can you please give me advise on what I need to learn? An software I need to get?

sprite render and loader is this:i.imgur.com/gobGZDr.png or this:i.imgur.com/UggYUFJ.png more explication: i.stack.imgur.com/m4C1T.png

Please, how can i make the same in c#?

How are you getting so many frames per second? VS isn't using much of my resources and I'm getting between 30-40 fps constantly. Edit: chaning from debug to release mode increases your frames

Hi. Thanks a lot, solve some problems in my collision detection routines. I'm sure you won't see that comment after two years of publishing but...well :) One question about the code on line 220 : why do you test "less or equal to zero ?" : if (fPlayerVelX 0) { //right... } I think it's a "speed coding" line with no real slow down on performance (on PC at least) but i'm a perfectionist so may be i'm wrong ? Another thing makes me perplex.. speed Y is camped at +100 / -100, i don't know the "fElapsedTime" value (may be 0.02 ?) cause i'm using another platform but it can be greater than 1 then greater than one tile and we can "pass through" some tiles vertically ? Am i wrong ? See no offense , i'm developping games for fun and have to learn "game specific" part of development so it's real question :) Thanks again for sharing your knowledge !

can i do the same thing with c++ and unity ? or is that over kill

Jario haha, mint.

Any tips if I want to add slopes to this project?

How do you handle slopes in a tile-based game?

I wonder if you could port these to other CMD accessible languages like C# or others.

Hey, very nice video, quick question does this program runs with only 1 cpp and 1 heather file (the engine) on the console game solution? or does it also needs to have the sprite editor, relay servers etc...

i dont understand I download the link and as I try to follow you none of the files are there?
