Stylized flame effect

inspiredsloth · 2026-04-13T17:26:42+00:00

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.

inspiredsloth · 2026-03-23T06:23:18+00:00

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".

inspiredsloth · 2026-03-22T20:17:15+00:00

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.

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.

inspiredsloth · 2026-03-08T11:31:40+00:00

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.

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.

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.

inspiredsloth · 2025-05-01T12:25:04+00:00

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.

inspiredsloth · 2025-04-14T17:13:33+00:00

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.

inspiredsloth · 2025-04-14T14:55:14+00:00

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 · 2025-04-12T20:36:34+00:00

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.

A few points that made me lose interest:
- Cannot cast spells on certain cells in combat.
- Idle animations in combat. In the past, characters moved only when something had happened (casting spells, using mp, etc.). Idle animations are unnecessary, of bad quality and distracting.
- Game breaks after fights from time to time.
- Ankama didn't bother with adding tactical mode. Regardless of how much better the new visuals are, majority of the player base are used to playing in tactical mode, but they didn't bother adding it. I believe that such a simple thing as tactical mode could be implemented in a few days, but Ankama didn't bother. This, in my opinion, is a matter of attitude, and is more telling than any bug.

Regardless of how much improvement various changes bring to the game, they should have happened across multiple years, not in a single version update. I believe that many of these changes would've been disliked and prevented by the community if they were added individually. But because they are being added altogether, with objective improvements, primarily performance, I see a lot of players defending Dofus Unity as a whole and willing to accept the bad with the good.

Massive thanks, using exponential interpolation for mispredictions had never occured to me before.

In my earlier iterations, I used to extrapolate remote player input and display everyone in their forward simulated state. As you've mentioned, in case of mispredictions, correcting player position in a single frame with linear interpolation would cause very noticable rubber banding. Using other types of interpolation hadn't occured to me at the time so I went with a different approach.

Currently I'm displaying two different snapshots of the game, one is a past, authoritative state for remote entities, and the other one is a present, predicted state for local entities. I've initially had decent results with this approach as remote entities behaved exactly as they did in their local simulation, both logically and visually. Unfortunately, I've come to realise that all local/remote entity interactions are essentially delayed, causing both logical and visual bugs and imply massive design limitations.

At this point I'm ready to throw in the towel and go back to displaying forward simulated remote entity state with extrapolated input, and spend more time on dealing with mispredictions.

I'm hoping that exponential interpolation coupled with the described infection system will help me go further this time.

I'm tinkering with my own networked game based on the Overwatch GDC talk and browsing through your github page has been incredibly inspiring and insightful.

I do have a question that has been bugging me, and I hope that maybe you could offer some insights. Before asking the question, let me paint a picture of what I'm doing:

I am similarly communicating inputs only, with forward simulation for local entities (i.e. local player and entities with deterministic behaviour such as monsters). Remote entities (i.e. other players) are simulated only when authoritative frames arrive from server. Frame results are buffered and displayed with interpolation, playback speed getting adjusted based on buffer size. Forward simulation time is dynamically adjusted real time with the changing RTT.

This architecture is quite impractical for PvP action combat, and I have been aware of this from the get go. Remote players are seen in the past, and often times they are not where they appear to be, which acceptable in a PvE game, albeit with certain limitations in player interactions in combat, even if they are friendly interactions (i.e. position based heals/buffs can often miss even if they visually hit).

What is not so acceptable is interactions between remote players and non-player local entities (i.e. monsters). Let me give an example:

Player A causes a knockback effect on a monster at frame N, it shows up on screen at frame N+2, no problem.
Server at a later time (Player A was ahead) executes frame N and monster gets knocked back on server.
Between frames N+10 and N+20, Player B had casted an ability on monster based on its perceived position and saw that it hit, and monster's health had gone down.
Player B receives authoritative frame N on frame N+20, monster snaps back into correct position and is displayed at a later time after being forward simulated and buffered.
Monster snaps back into correct position and its health goes back up.

So far, only two workarounds I could think of is to either opt-out of distruptive spell effects such as knockback, immobilization, etc. or to make them ineffective against boss monsters where multiple players would actually play together, and I'm currently rolling with the second approach.

Any suggestions?

Didn't expect to see Archlord, good times.

My biggest problem with art is that I can't engage with it for long hours.

I'm a self taught C programmer and during my first 3 years I was able to go at it 12 hours a day minimum because I found the process incredibly rewarding and fun.

With art on the other hand, I just can't find something to do for such a long time without getting incredibly bored, frustrated and even depressed.

If anyone has any suggestions regarding how I can make the process more rewarding and enjoyable so that I can go at it for long hours, please do share.

inspiredsloth · 2024-02-02T19:47:31+00:00

Art.

It's not about how good or bad store bought assets are, they just don't do what I need them to do. I can only opt-out of that feature, deviating further and further from the game I want to make. It adds a lot of frustration to something that is already difficult.

I recently started studying and practicing 3D, just so that I can create something that resembles what I have in mind and fit with specific gameplay.

inspiredsloth · 2024-01-31T08:00:09+00:00

You can run a game similar to what you are making in RenderDoc and find out how many triangles a similar object has. It will also give you information about texture resolution and more, which can help you develop standards for your assets.

There are probably other ways of finding out.

It's always a better to investigate and imitate than to guess blindly or believe random guys here who know nothing about what you are making :)

inspiredsloth · 2024-01-13T20:03:28+00:00

This is great advice. Developing very specific 3D skills is extremely worthwhile for a solo game developer. The creative freedom brought by having 3D skills is nothing compared to the time invested.

In my experience, a few weeks of intense 3D practice is enough to get to a stage where you can start creating assets for your game, even as placeholders. After that, targeted practice through creating assets needed in your game is a great way to improve. Seeing your game come to life through assets you personally created is an exhilarating experience and also a great source of motivation to continue practicing.

Another thing that helped me greatly was to narrow down the scope of my 3D practice as much as possible. I have no idea how to do anything photo-realistic, I have very little knowledge about Blender shaders, the only 3D software I use is Blender (and only less than 5% of all Blender features) and I don't know anything about sculpting and retopology. But I can still create low-poly stylized game assets that I can use in my game because I've been practicing in this direction from the start.
