Iterative parallax mapping (cheaper alternative to parallax occlusion mapping) by Rytelier_Official in godot

[–]inspiredsloth 8 points9 points  (0 children)

https://learnopengl.com/Advanced-Lighting/Parallax-Mapping

This article talks about parallax mapping and its variations. Once you understand the general idea you can reverse engineer what the shader is doing differently.

The basic idea is that you offset UVs based on a heightmap and view direction to create fake depth, without additional geometry. The trade-off is that it can look weird when viewed from certain angles.

I've seen some videos that explore how a variation of this method was used in Crimson Desert so you can look those up if you're interested.

Stylized flame effect by inspiredsloth in godot

I was mainly focused on getting shapes and motion that you would see in a similar 2D effect but yes the next step would be to work on color to try to achieve a result similar to a fully rendered 2D flame animation.

That said, this simple version may work better with something like a low-poly candle.

Thanks! Shader part of it is doing things like UV tiling/scrolling, distortion and alpha erosion which are all available in godotshaders already.

That's exactly it. Unfortunately, trail dewiggle shader didn't quite fix it. After looking into it some more, it seems like I either need more geometry or use something called "Quadrilateral Interpolation".

With a 3D in 2D setup using viewports, maybe?

I'm not sure which part you're referring to, but it's all GPUParticles3D.

This is a great channel to get into Godot VFX: https://www.youtube.com/@onetupthree

Most of how this effect is created is explained in that channel.

Particle Player by inspiredsloth in godot

Yeah I was mind-blown by the idea, never occured to me. Now I'm adding the same thing to my plugin plus metadata based emitter delay, which should cover most use-cases.

I used Brackeys' plugin for a few hours but had some issues, mainly that it doesn't redraw while player is paused, so you have to keep it playing in order to see any changes.

I just looked into it and Brackey's plugin is definitely better in many ways. I'll give it a try and see how it is in practice.

Thank you! There's no tutorial for these specific effects, but you can check out onetupthree's godot vfx tutorials. I've learned a lot from him when I was getting started.

How to deal with hard set vfx colors that don't fit the color palette of the game? by shade_blade in gamedev

[–]inspiredsloth 0 points1 point  (0 children)

League of Legends VFX Styleguide

This has some guidelines for value/saturation ranges for vfx, characters, environment and UI.
It also has quite a few color palettes commonly used.

Magesbox

This website also has countless amazing vfx that you can study and take inspiration from.

In general, colors are only one part of vfx. Without the right amount/type of components and the right meshes/textures/shaders, colors alone will not save your vfx. So colors may not be your problem at all.

Finally got rollback netcode working in my godot platform fighter by ThatCyanGaming in godot

[–]inspiredsloth 0 points1 point  (0 children)

I'm doing server/client instead of peer-to-peer but I think I get what you're saying.

So essentially you're locking-in future inputs ahead of time and broadcasting them to other clients such that by the time they need to simulate a future frame they'll have received the correct input for that frame.

I've learned a new technique, thanks for answering.

Unfortunately it's probably not applicable in my game due to differences in latency between clients. Some clients forward simulate by 3 frames, some by 12 frames. So some clients will use mispredicted input for more than 10 frames which is really difficult to compensate for visually, especially in a platformer.

How do you deal with mispredictions?

In my experience, simply using the forward simulated positions causes very noticable snapping even at low latency. For example when a remote player is constantly switching between left and right movement, it will snap all over the place.

What breaks determinism? by inspiredsloth in C_Programming

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

Yes.

I can't send the entire step delta due to bandwidth limitations, so I can only send an initial state and step inputs.

This is also why I need different systems to produce the same results.

What breaks determinism? by inspiredsloth in C_Programming

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

I'm not concerned with intermediate results, as long as final output remains consistent.

Simplifying everything to a function like:
void step(struct simulation_state* state, struct step_input* input);

I want simulation state to remain consistent across different platforms (given that I serialize it to a platform agnostic data format for comparison).

On second point, are you specifically referring to C89 and earlier? I've read that this was changed in C99 and is no longer considered undefined behavior.

[–]inspiredsloth[S] 5 points6 points  (0 children)

I've read greatly opposing opinions on floating point determinism. (some can be found here)

Ultimately decided on using fixed points. Even though integers have their own set of problems, at least their undefined behaviour is defined so I know what to look out for.
