About the *crafting table algorithm*. A lot of you have pointed out that it is grossly inefficient, and I should swap it out for some hash and compare algorithm. This is true, but let's do a little thought experiment. According to the table here: www.agner.org/optimize/instruction_tables.pdf, it looks like comparing two 32 bit integers takes about 3 cycles for Intel Sandy Bridge (an i5 processor), assuming no cache misses etc. You need to move two numbers, which requires 1 cycle each (also ignoring reciprocal throughput), then compare, which takes 1 cycle (ignoring reciprocal throughput). My crafting table consists of a 16 bit number for the item id, and an 8 bit number for the item count for each slot. So, let's round it up to 32 bits and assume comparing two slots is the same as comparing two 32 bit numbers. That means it takes around 3 cycles each to compare two slots. If I compare my crafting table to one recipe, that's 9 slot comparisons total, or around 9 x 3 = 27 cycles. So, if I go ahead and say that I have 1,000 recipes to check against, then that's a whopping 27 x 1000 = 2,700 cycles. On an Intel i5 with a clock speed of 1.6 GHz, or 1.6 billion cycles per second. One frame of a game is 16ms, so lets say we have 1.6 billion * 0.016 = 25,600,000 cycles in one frame of our game at 60fps. This means that checking if the user got 1 recipe out of 1,000 possible recipes would take around 0.01% of our total frame time, or around 1.69 microseconds :). If we have 10,000 recipes, that would take around 0.1% of our total frame time, still not even 1% of our processing power in one frame. Now of course this ignores cache misses and all that stuff, but the point I'm trying to make is brute force is not always the worst solution. It's often the simplest algorithm, which it definitely is in this case, which leads to less bugs. Keep in mind that I only run this algorithm when the player updates a block in the crafting table. Human reaction speed is around 0.186 seconds at its fastest according to Google. In other words, they probably won't be clicking fast enough to ever have a lag spike because of this algorithm. Collin Ames did some calculations with cache misses taken into account in the comments, and calculated it to around 20 microseconds for comparing 1,000 recipes if you're interested :) I *always* profile my code *before* trying to optimize stuff, and my hottest path is anything that has to do with updating a chunk. One chunk is 16x16x256=65,536 blocks, each 64 bits. That's a much much larger loop than checking a crafting recipe, and that's where I focus most of my attention when optimizing my code (it also turns out to be the hottest path every time I profile it). So, when I completed this algorithm, and it didn't show up as a hot path, I moved on to other problems since I only have so much bandwidth as a solo developer :) TLDR; Don't assume where the hot paths in your code are, profile it. You'll learn way more that way ;)

@Harrison I definitely have the same problem of optimizing stuff that probably doesn't matter :pain:. And the hashing is still an awesome solution that's pretty straightforward and I wish I would have thought of :). It's also pretty simple, so I'll go ahead and implement it if I have some spare time, but when I coded this my gut feeling was "this probably won't effect performance as much as most of my other code", and I probably should have verbalized that a bit better in the video :)

I want to start out by saying that it's great to see your analysis of this, and you have a good process for solo development. I'm just responding to this as a thought experiment :) IMO, there are two flaws in your logic that make the original implementation unjustifiable: 1. You talk lots about the performance of this algorithm. Let's assume that Collin is right, and this takes 20μs to compare 1,000 recipes (b/c I'm a lazy programmer and don't want to do the math myself). If you expand that information to your 10,000 recipe example, it's now taking 1.2% of your processor cycles at 60Hz. I'm not sure why 1% of a frame at 60Hz is where you drew the line, but that's already quite substantial for what should be a cheap algorithm, and it's entirely possible to go over 10,000 recipes with recipe variations in modded Minecraft. 2. You say "[Brute force is] often the simplest algorithm, which it definitely is in this case, which leads to less bugs." The only way this could possibly be true is if you've never heard of java.util's Map class (or C++'s std::map). This class trivializes recipe checks so much that I can write the Java implementation legibly in a youtube comment: recipeMap.containsKey(currentRecipe). There's no way that an iterative method could be simpler or have fewer bugs than a single function call from a standard library. A couple other corrections (though they don't change your argument much): 1. You say "Human reaction speed is around 0.186 seconds at its fastest according to Google. In other words, they probably won't be clicking fast enough to ever have a lag spike..." Here, you are looking up information that doesn't measure what you're talking about. What you're looking for is clicks per second, which seems to top out around 14 clicks/sec. That results in one click about every 0.07 seconds, which means this algorithm could run three times in a single frame at 60Hz, tripling its cost to 3.6% of your budget in the worst case. 2. You say "One frame of a game is 16ms." This is obviously false, but I understand that you meant to say "I'm targeting 60Hz for this game." Your rounding (16.66... -> 16) also causes your estimates to be more conservative, so there's no problem there. The underlying assumptions you're making, though, are increasingly problematic. More and more consumers are buying displays that support 120Hz and variable refresh rates, and new consoles are taking advantage of these features. To support both VRR and people who don't use V-Sync, you should be looking at your frame pacing (time between frames) as well. Also, just a general comment on profiling - there are times when you'll have to profile one specific scenario to "light up" a code path. This specific code path isn't run for 99.9% of frames, so it obviously won't show up as a hot path if you profile with normal gameplay. That doesn't mean that players won't notice it when it does show up, and if you wait until you get user feedback ("Every time I craft something, my mouse lags"), it will probably take a lot longer to figure out what's happening.

@@dallasjohnson2635 maybe I should have phrased the original comment as "this is just some napkin math to illustrate a point" haha. I appreciate the response, but I'm just trying to illustrate that this algorithm runs on such a small data set that it's not worth my time to optimize it for a microsecond (at most) performance improvement per frame. A lot of people like to look at one specific algorithm, but a game is thousands of algorithms running simultaneously, and it's _always_ better to look at the algorithm _in context_ :) 1. I chose 1,000 recipes as a crazy outrageous number that I'll most likely never reach. According to the Minecraft wiki minecraft.fandom.com/wiki/Crafting#Recipe_system there are only 379 recipes in vanilla Minecraft as of 1.16. So I think I have plenty of time before I begin reaching 1-10,000 recipes lol 2. I think this is a bit disingenuous. Sure the API for a Java Map or C++'s std::unordered_map is simple, but you still have to implement the equality operation to ensure that it knows how to check if two recipes are the same (which is the same code I wrote anyways). You also have to implement a good hash, otherwise the map doesn't help much at all, and can often be just as bad as a regular linear search, check out this SO question stackoverflow.com/questions/1757363/java-hashmap-performance-optimization-alternative . This requires a lot of extra knowledge and implicit complexity. For your last two comments, I am targeting 60 fps, maybe I'll target a higher frame rate in the future. And once again, the reaction speed was just for napkin math to do some quick comparisons :) And when I profile, I do target specific events when I'm profiling a certain section of code (Visual Studio allows you to actually select the time period you would like to profile which is very helpful in this regard). My point was that comparing crafting recipes is literally orders of magnitude less then simply iterating over one chunk (400 recipes compared to 65,536 blocks in one chunk). There's usually 12 x 12 x 3.14 chunks in the game at the default settings (that's around 29,600,000 blocks, 74,000 times larger than all the recipes). This means that if a player is going to be noticing lag, it's most likely going to be when doing anything with chunks. All this to say, yes I know the hash is a better algorithm. But right now, as my code is, I'm not going to spend a bunch of time optimizing an algorithm for a few more microseconds per frame. If the requirements change, and I have to find 1 recipe out of 10,000, then I'll change the algorithm :)

That plan to make your own game based on the engine is really exciting. That ambient occlusion really makes it look good.

You can actually use both TCP and UDP. Just connect to a server twice on two different ports. We used that in our own multiplayer. We sent important messages like player join notifications and chat messages on one and player position data on the other Instead of sending packages every single frame and delaying them you can just send them more rarely and interpolate between received results. It's a lot easier on the server and delay is as short as possible. Once you received a package where player started moving in certain direction you can just complete that movement until new package arrives, when you will just correct player's course to align with new data Also slabs are horizontal in Minecraft :)

Rubber banding is a side effect of client prediction that is incorrect from the server. You can avoid rubber banding with interpolation to make perceived latency less noticeable. Of course, this compromise also means that hit boxes aren't accurate and optimistic updates can cause data loss (i.e. crafted item wasn't received or verified correctly by the server) in high latency servers.

@@LuisCassih It will definitely will feel bad when you have a long latency. I don't know how Valorant client prediction works and when it kicks in. But a common practice is to use server reconciliation to solve desynchronization issues by sending a sequence number with the data, which can then be used to reconcile commands later on the client. Then reapply those commands that haven't yet been predicted by the client. That way it doesn't need to re-run commands that have already been predicted, while ensuring consistency with the server for both high and low latency players. This is how QuakeWorld (and Half-Life et el.) works.

Great work on this so far. At some point it would be good to see a non constant velocity when moving, using acceleration and deceleration, in Minecraft this is subtle but it makes a big difference. Another thing I can suggest is to work out the longest time a player takes to ping on the server and set the buffer time accordingly; if two players on the same LAN network have to deal with 300ms of ping it could be quite annoying. For a larger server you'd probably want to take the median ping of all players and set the time to that, so one player having a hugely high ping does not affect everyone else too much. Also, consider that players can cheat as the clients are just telling the server where they are going, the server is not confirming or denying whether this is possible or not. Some games solve this by only sending what inputs are being given and the server confirming what should happen, while the client predicts what it believes should happen.

This is amazing! Making your own game out of this is brilliant, finally someone has that idea! I've seen so much potential in these Minecraft copies devs make, but they never try to actually make a game out of it that would be better than Minecraft, something different. There's so many things I wish Minecraft would be like, but it never happened. From simple things like improved physics to more realistic crafting to making cubes smaller, so that there's a lot more options to create things and how they would look like. Also, congrats on making multiplayer possible, I bet it wasn't easy. UDP is the best choice and there are also different types of UDPs like RUDP. I just think about if 300 ms of buffering would be good enough for PvP for example. I imagine CoD MP has figured this out in much more complicated way. They are probably checking who fired first and what were the real locations on their client side, but somehow it has to calculate probability most likely. And there are also problems with hacking and all that crap. There also have to be the distance prioritization to sync player's location. Multiplayer is just very difficult to make.

Thanks for the video

A full 3 minutes is 180 seconds; 240 is the windows default of 4 minutes. the true default is anywhere from 5 minutes to 15 minutes, depending on the RFC / standard you're going by.

4:17 This section doesn't sound right to me, the round trip does not affect the time between packets. If you send a packet 60 times per second you wouldn't see a difference in time between each movement at 1/2 the round trip time. You would just see their movement at 60 times per second (ignoring dropped packets) with a delay of 1/2 the round trip time as that is how long it takes for those packets to get there. The only way you would see something like 5fps for that example would be if you actually waited for an ack before sending a new position packet. 8:00 I'm really confused as to why this is considered an issue. It's 3 minutes before we consider the connection to be dead and kick the player, you should have something like this implemented to handle a situation where the game is improperly closed such as the user's computer turning off from a storm. Something unclear to me as you're using a buffer and unreliable packets for position, is whether you timestamp the positions in the buffer or wait for it to fill to update the visible position. If you're just waiting for the buffer to fill you can have issues from dropped packets causing the positions updates to slowly increase in delay. The buffer solution also sounds like it may have been picked for Quake for reasons other than smooth movement, with dropped packets it may still appear choppy unless interpolation is added.

@GamesWithGabe

2 жыл бұрын

Yep that's true, sorry if I misconstrued that first part :) At 8:00 I'm alluding to the fact that with TCP it has to continue retrying to send that missing packet. If you missed a packet like a player position update, that data really doesn't matter since it's most likely out of date anyways by the time you realize that you missed the packet. But TCP will continue blindly retrying to send that data until it receives it because of the way the protocol works, and that will create a buildup of other unsent packets since they are all waiting for that one missing packet. (Yes I know that TCP probably sends the newer packets as well and just reorders the packets client side once it retrieves all them) I do timestamp positions :). They get inserted into the buffer in the correct order and I also interpolate between the two nearest packets whenever I'm playing the position back client side. Unfortunately when uploading content to YT, it's usually best to gloss over a lot of details to make the video more interesting. I was also trying to condense over 3 months of research and work into a 20 minute video, and as a result it's going to be missing a lot of details because it's impossible to relay all the information in such a short video :)

Everyone says that the crafting could be made better by hashes but I think the real optimization would be this: When we are checking recipes that could be crafted in different shapes( torch for example) we should firstly somehow normalized the recipe. In this case the great normalization would be shift everything to the left and to the top as much as possible and then only checking one recipe and not different combinations

to optimize the checking for the stick recipe you could just check the middle row, and if you find nothing that matches, then discard it, if you find a plank, check above and below it, and if it matches make sure all the unchecked other slots are empty. Doing it this way would make it so you only need to check every slot once.

Imagina creating algorithms for almost every crafting recipe. That wouldn't be very efficient

Multicast sounds nice.

Im ready to start test this game and make videos about it

That would be awesome :D . I'm currently coding a self-updating game launcher so that I can distribute the game. I'll leave a community post once I have it working so that people can download the game and play it :)

@@GamesWithGabe 🙌🙌🙌 I know coding is really much time consuming expecially when you stuck in some part where you don't understand it and you looking for answer taking some break time could help for future progress, 🙌 it's amazing that you achieve to this level, also the idea to convert your project to your own game title is nice idea

I think using a hashset to determine the recipe would be more efficient if you were to have a large number of recipes

I'm a big fan now

now i realize how much effort was put into those free "minecraft" games on the app store when i was 10

I like your funny words magic man

Nice! Now I wanna try doing this! Lol

Finally minecraft clone which is not a total bullshite. Couple of things: make sure to actually test multiplayer with slow connection (e.g. using vps). Original Doom multiplayer was bad because Karmack had fast cable.

Awesome :o

You could also translate the recipes to the upper corner then check.

17:00 this really sounds like idea I had basically minecraft + dont starve in short

I hope they implement RGB lighting into vanilla at some point in the future.

Really cool, learning about these multiplayer solutions! I feel like programmers had to be so much smarter back in the day

I agree. I feel ashamed when I'll use several MB of ram to do a relatively simple task instead of coming up with a smart solution like they had to do when they had a few KB of ram haha

@@GamesWithGabe I'm a noob, but I'm wondering if it's worth it to optimize tasks in a way that uses very little memory? Would it make the game run better? I'm curious how to optimize an app or a game as much as possible and if it's worth the labor to do that?

So its been a while since i thought about this sort of thing so i might be wrong, but would the crafting recipe be faster if it just hashed what was currently in the table into a pointer that lead to the result of the recipe instead of checking the spaces?

awesome video

This clone is the closest looking one to Minecraft, might be because the guy's following the same path Notch did. Hoping you'll get yourself 2.5 billion and nothing controversial in the way!

very cool !

btw if that's supposed to be seattle or tacoma on the internet map it's a bit off if it's supposed to be portland it's nearly there

Finally, :D

Does it check the blank boxes on the input? Seems like that would slow it down a little. Your example implies it does. I'm just curious.

Yey, it looks like someone is about to recreate minecraft but whit out all the controversial updates :D

Did you use 3b1b's python library for the video animations? (Like the crafting animations)

not sure but would adding categories for the recipes and grouping them like wood item iron etc?
