@adhochero6619 4 года назад

wow those improvements are insane. still not 100% sure how to implement it in full games. would you do a tutorial on building a basic game with these new systems, with controllable player and enemies and health and all that?

@mjaada 2 года назад

In the first example Burst compiler removes the loop completely because the calculated value is not used after, if you make it so that you do use it, the performance gained is much less

@AiSponge2 5 месяцев назад

are you sure the burst compiler is not ignoring the instructions because it's a dead function, I doubt that it improved it by 100x

@AiSponge2 5 месяцев назад

exactly this is what I thought@@mjaada

It's like anything, really. A lot of people jump in and dabble to see if they like something but only those few dedicated will keep learning. That's why the beginner videos get the most views but these videos are actually the most helpful.

@peterarndt8475 4 года назад

Thank you so much for this video. As an amateur with about half a year of programming experience, I'm still trying to get to grips with the implementation of concepts like thread safety and lambda expressions. Every other tutorial and instructional source I watched seemed to assume the viewer/reader was completely familiar with this level of coding and more, and only went through the syntax. You actually took the time to run through the basic logic of the code at a reasonable pace, which was so much more helpful.

@meowsqueak 3 года назад

The reason your cycle time improves so dramatically when you enable Burst Compile is because the burst compiler optimises your mathematical expression to a constant value. Ideally you’d use an iterative function and reuse the previous result, and eventually use the final value to prevent the compiler optimising it all away.

@mrx10001 Год назад

Can you give an example of an interative function vs a non interative function?

@scottbarley7760 Год назад

@@mrx10001PerlinNoise is a good example I think, as its constantly changing, so cant be simplified to a single value by the complier; float[,] mapValues = new float[size, size]; for (int i = 0; i < size; i++) { for (int j = 0; j < size; j++) { mapValues[i, j] = Mathf.PerlinNoise(i * 0.01f, j * 0.01f); } }

Top-notch tutorials on Job System and ECS! I'm really glad you aren't just skimming over existing code which is hard for me to follow. I'm looking forward to see more videos from you on this matter.

@enitalp 2 года назад

PS : The initial boost you get by enabling burstcompiler, is just the fact that your function actually does nothing, so the compiler optimized your code by removing it ;p Doing a calculation is not doing something, using the result for another thread or to display is actually doing something, When dealing with optimization it's hard to make a code that actually does something, Compiler are kind of very intelligent. The fastest code is the code you don't execute ;p

@warmbreezerising 5 лет назад

Thanks for all those good videos. I really like to say this is Great (or GREAT) job. They are all very clear, straight to the point, still providing good explanation and concrete examples. This is true for all your videos, showing ways to do this or that (implement a minimap, whatever), but also for explaining new features. And concerning this, your videos about DOTS are really really great: concrete explanation and illustration of DOTS which for me compensate for the poor unity documentation, and complements unity videos (gdc ones are good, but your provide better explanations). Best of it: they're up-to-date: with APIs change, it's hard to find up-to-date and accurate examples. I follow some unity youtubers, they're all good and very interesting, but you're most certainly one of the best. Overall video qualities: 10/10. Thanks so much :)

@rcdemoral1982 4 года назад

FYI: If you are using any of the methods for UnityEngine.Random (like Random.Range (-10, 10)) and you are "using Unity.Mathematics", then there is an error regarding ambiguity between Mathematics.Random and UnityEngine.Random, even though there isn't a random function for "math.". You have to add "using Random = UnityEngine.Random;".

First of all you are really awesome for taking the time to do these videos. These take a lot of time to put together and I just wanted you to know that it's appreciated. Second, I am having strange results trying this on my own, when doing the hard math, the one that simulates a costly operation, I can mimic your results, burst compiler plus jobs yields an incredible gains. However, both methods for moving sprites, ends up actually being twice as slow, the opposite results.

@magnusm4 20 дней назад

I started by remembering a video on MMO optimization where a charge isn't done sending their position constantly. But instead it's a single lerp function doing the math for one task. That made me look up the benefits and difference of coroutines and async. And ended up with Jobs. I would love to post optimize my code with this for larger tasks. My main idea right now is object pooling generic projectiles and use some async/Jobs to calculate the trajectory instead of doing it with physics rigidbody.

These tutorials are great and I thank you for being the first to finally allow me to get my head around ECS but one thing I can't get my head around is doing something more complex in job system, like the pathfinding you mention, say you are using A* for your pathing method, would you need to pass in the whole map data to a native array first in some fashion?

@CodeMonkeyUnity 5 лет назад

Every job requires a complete copy of the data necessary so yes you would pass all the necessary A* map data to every job calculating a path.

@@CodeMonkeyUnity I can see it as an amazing tool for the pathfinding of an rts. But for most of the things that happen in an rts you need different objects to interact with each other.
