If you've never used ECS before then this video is for you. ECS is great for game's with LOADS of entities, so I figured why not make a shooter that attemps something INSANE that a normal monobehavior approach wouldn't be able to handle (50 projectiles per frame....WITH physics and enemies you can damage)
I hope you enjoy! And I hope ECS inspires you to create more ambitious games!

Hey all! If you want your bullets to spawn the same way they do in the video thumbnail: In your PlayerSystem script: Use this line for your bulletTransform.Position: bulletTransform.Position = playerTransform.Position + playerTransform.Right() * 1.65f + bulletTransform.Up() * randomOffset - bulletTransform.Right() * math.abs(randomOffset);

Very concise and easy to follow. Thank you for the brief explanation. Looking forward to part 2!

Great job! Hope to see a full game with your ECS tutorial series. It's a new thing for many developers and I think you can feel free to explain even more of how each of the systems works or some other why`s. Like i would love to know more about the Burst compatibility concerns you mentioned at the end of the video :) Keep it up!

I adore the ECS, however I also severely dislike how every game prototype made with it completely lacks animations. The car flight game was a nice move by Unity team because cars don't need animation.

Interesting approach to teaching ECS. I feel like every other tutorial about ECS spends so much time on well.. ECS itself. But you're just going straight for it, how to make this thing. On one hand having already consumed a decent amount and basically understanding ECS already that makes this super easy to understand and consume, on the other hand I think for people who aren't all that well versed in ECS this might be a bit tough. We'll see. Good job.

I respect the awesome power of ECS and DOTS, but I'd be lying if I said this workflow and having to relearn all the syntax didn't make my brain and soul hurt.

Hey bro... it's a suggestion... how about building a complete course from beginner to intermediate. I think it will be very useful for everyone who wants to understand DOTS but didn't know where to start.

@ImmortalTimothyM 3 ай бұрын

I agree, however in the meantime there is a KZfaqr named Turbo Makes Games that has a lot of videos on Dots and ECS. Unsure how good they are because I have not went through them yet, but the videos seemed good on my initial impression.

As someone who wants to make shmups, I wish there were more tutorials like this for the Godot engine.

WOW

@Chrispins Ай бұрын

Hey do you think BulletLifeTimeComponent and BulletComponent could have been lumped together into a single component since you can't really have one without the other in most cases? Or is it somehow more efficient to keep them separate? Just trying to get a feel for the proper ECS philosophies.

@Chrispins Ай бұрын

Also, since the rotation and scale of a bullet is not really necessary (the rotation can be automatically derived from it's velocity instead), I wonder is there a way to give bullets a Position only component without using all of LocalTransform, which is slightly wasteful for the data cache in ECS if I'm not mistaken?

that might be an editor thing, performance is normally better in build

@user-rm2pj9jf8s 3 ай бұрын

May I ask a question because I don't quite understand? Like you, I want to create a system where bullets are fired massively at the end. Is it okay to use ECS (Entity Component System) only for bullet creation, and not for other systems? I'm not familiar with the concept of ECS, so it would be difficult to modify all systems, but I would like to implement just the bullet creation using ECS. You wrote all your code to suit ECS, but I want to use ECS only for bullets. Have I effectively leveraged the advantages of ECS? I apologize for the frustrating and basic question, but I would appreciate your response. In other words, is it effective to configure only some systems with ECS instead of using ECS for all systems?

@iFAKEYx 3 ай бұрын

You can have a mix of mono behaviors and ECS. So yes you can only do the bullets

@rrainix Ай бұрын

yes but i think if you want to acces the position of the ship, so that you can set the direction for the bullets won't be possible anymore. Only if you would still store the ship as an entity it would be. Then you could controll it via Monobehaviour.

30 to 45 batches in drawcalls...not bad at all... But I think I will learn GODOT... BRACKEYS is back and got me motivated to learn open source again...I have a few ideas for new viral games!

If Godot finds out how to do ECS better than Unity, I'll never go back.

@ragerungames 3 ай бұрын

Never blindly follow trends, mate. Follow your heart's desire. Both Godot and Unity are game engines, and at this stage, the distinction between open source and proprietary might not matter much. Currently, Unity offers features comparable to or even better than what you'd find in Godot. While you can't access Unity's engine code, ask yourself if it truly matters to understand what's happening behind the scenes. Ultimately, choose the engine that aligns best with your vision and goals.
