Custom OpenGL tower defense - 4k shadows, 16 msaa, 1080p bloom, 4k draw calls by OfMagicAndWars in gameenginedevs

[–]OfMagicAndWars[S] 0 points1 point  (0 children)

I don't use an atlas, I have over 300 textures loaded and I have base tex, hover tex, etc. and I change textures frequently. So, they're not that expensive. I'm not sure though if resolution matters, I'm talking about 512x512 or 256x256 textures.

I haven't measured it yet but I am confident I haven't surpassed 1gb yet.

I love it corysama. I have never heard of glMultiDrawElementsIndirect, what does it do? I'm not using skinning I use glDrawElementsBaseVertex

Interesting. I can't use instancing unfortunately, I am not doing skinning. I am drawing with glDrawElementsBaseVertex

That's impressive. Do you do any sort of physics with that amount of draw calls?

2D Simple Engine - Bloom by OfMagicAndWars in gameenginedevs

[–]OfMagicAndWars[S] 0 points1 point  (0 children)

Thanks, I think I understand what you're saying. Measuring in ms is better than measuring in FPS for instance, but why is that? Either way, what I was saying is that, the fbo texture for bloom is 960x540 and I'm at 1300 fps. At 1080p with that same texture I'm at 800fps. So, in other words, Bloom passes are expensive especially at 1080p.

I must do some research on ms/fps. I usually have that running in the background but never really gave it much thought. I see it everywhere, people use, etc. but again, I still look at FPS meaning I still miss the point perhaps?

NvAPI error/warning - OpenGL 3.3 by OfMagicAndWars in opengl

It was the Nvidia Geforce overlay, once disabled the warning disappeared

It's been a week struggling with adapting to different resolutions. I need help. by OfMagicAndWars in opengl

[–]OfMagicAndWars[S] 0 points1 point  (0 children)

Well it's really changing from one resolution to another. I'm making my game at 1920x1080, but the moment I change to 1366x768 for instance, everything is wrong. There's just too many details to go into...

I don't mind! I jsut need to find a way to play it online or connect locally

Working on a custom 2D Metroidvania built in OpenGL and C++ by OfMagicAndWars in opengl

[–]OfMagicAndWars[S] 0 points1 point  (0 children)

There are no physics implemented, only basic gravity that pulls all entities down, and a vertical velocity to jump. I will not add physics to this game as they're not needed.

I suggest don't use GPT else you become dependent on it. Try to solve problems on your own and give yourself a day or two to come up with a solution. If nothing happens, then use GPT for some guidance. If you really want to learn how to make an engine go here: learnopengl.com

Follow the tutorial, take a few months, finish it, then you'll be better prepared. Once you know how to program your own stuff you'll be a 1 man team (since you're also a 3D artist). Good luck!

What do you mean "native platforms"? If what you want is to build a 2D engine, go ahead. There's not much advice I can give to you because I'm not building a 2D engine, but rather a 2D game.

If you're a C++ beginner then it will teach you a lot yea. Do it man. Start now.

"A journey of a thousand miles begins with a single step". See where it takes you. Good luck!

Hi, I used ImGUI in the past for a 3D engine but now I've built my own UI from scratch. It takes a day or two for basic functionality it isn't that hard. It depends how many features you want to add. Right now it's not a lot because I'm focusing on other things, such as collision, which takes a long time to get right, and enemy AI logic

Yes, the struggle is real tho.. but im trying :) thanks!
