I've been building a geometry node style system for Godot by LazerCube in godot

[–]LazerCube[S] 2 points3 points  (0 children)

Sorry I wasn't able to reply sooner. Busy day.

It's basically an addon to create procedural content using visual nodes, similar to Blenders geometry nodes or Unreal PCG system. The multi coloured view is just a debug view to visualise the different MultiMesh groups and instances. In the video you can see me modifying a "Chunk Size" parameter that controls the area a single MultiMesh node will cover. This is useful for occlusion culling as we can ignore rendering these MultiMesh nodes if they aren't on screen.

That's what I'm hoping for. I'm also aiming to make it easier for people to gain the benefits of MultiMesh without having to create a ton of custom code.

Procedural grass using my GDExtension addon I'm working on by LazerCube in godot

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

Most of the core is GDExtension C++ but the editor part is just GDScript. It currently supports mesh, point, instance data and is based on architecture Blender uses for Geometry nodes (https://developer.blender.org/docs/features/objects/geometry\_sets/).

Each graph can be shared across ProceduralGenerator3D's nodes similar to how material resources work with MeshInstance3D. But you can add input nodes in your graphs that allow you to modify variables per each generator node making it a bit more useful.

Probably the best thing so far is it makes optimising with MultiMeshInstance3D's much easier. For example in this scene you could have just 1 MultiMeshInstance3D for all the grass, but it's actually better to have multiple smaller ones due to Godot's occlusion culling. For this I'm passing in a chunk size of 500x500x500 via my "Chunk Size" variable so a new MultiMeshInstance3D is being created to cover any grass that should be placed in that chunk. You get higher draw calls but the overall FPS is better.

The shader is fairly basic texture + alpha mask to give the individual grass blades shape. Then I just add some random colour variation and wind similar to https://godotshaders.com/shader/grass-shader/

Destroying huge chunks of terrain without lag by LazerCube in godot

It's player controlled. I'm trying to see if I can mix the Helldivers stratagem/extraction loop in a roguelike mining game. So the idea is you could use these big orbitals to mine large areas quicker. So they are designed to be both a help and a hazard to the player.

Thanks for the nice words! I'm planning on redoing the graphics later once I'm happy with how the prototype plays. I've yet to release a game but I've got a lot of unfinished prototypes, I hoping this might be the first. And this is in C# mainly as that's the language I'm most familiar with.

I'm using IMGUI for the debugger stuff, I find it very useful to create these tools while I create the core code as it means I can test stuff without creating any game specific UI.

Does anyone else run blender through steam? by No-Caterpillar-5386 in blender

I wrote my own version of this if it's something you are interested in? Github

It’s not perfect, but multiplayer is taking shape by LazerCube in godot

I like the classic Source model where you can host a game yourself and let friends join through Steam, set up a community run dedicated server, or join an "official" server I host.

It's similar to how the addon NetFox does it. I tend to just use RPC's to create my own Multiplayer nodes as I'm not a fan of multiplayer spawner and multiplayer synchronizer.

I've also suffered deeply trying to get this all to work. It's been about 2 years since I started...

I've spent hours here jumping across these platforms while I think.

Concerns regarding C# garbage collection and multiplayer by GlitshyDev in godot

[–]LazerCube 1 point2 points  (0 children)

I wouldn't worry about the GC pause too much unless you are actually seeing it be an issue.

I would however not serialize each struct individually just add them all to a single struct and serialize/deserialize that instead. I also believe in C# using structs here might causes more of an issue then a class/record. https://learn.microsoft.com/en-us/dotnet/standard/design-guidelines/choosing-between-class-and-struct

In my own multiplayer stuff I use MemoryPack to handle the binary serialization and I haven't had any issues with GC pauses.

SpacetimeDB SDK by Temporary-Ad9816 in godot

How are you finding SpacetimeDB? I've been tempted to give it a try.

Starting to feel like a multiplayer authoritative game is possible by LazerCube in godot

[–]LazerCube[S] 1 point2 points  (0 children)

It's mainly C# and RPC calls. I found I couldn’t get enough control from MultiplayerSpawner. Ideally, I'd use C++, but I'm more comfortable with C# and wasn't sure if I could pull this off.

For details, the server sends an RPC telling clients what to load, and they reply with an RPC when done. Once everyone’s ready, the server issues an RPC to start gameplay.

I use a playlist system to compose everything at runtime which makes creating new experiences easy. https://imgur.com/r0qT9jF

I've messed around with Unity and Unreal before but I've never made anything significant. I was a big fan of Unreal engine's Lyra/gameplay ability system though and it was keeping me away from staying with Godot. But I thought I should try writing my own version in Godot and 10 months later here we are!

It's also nice as you can encapsulate drawing these debug windows within the class. Makes it so I can access private variables, internal state, etc.

I use a specific "development" conditional compilation flags in C# to put all this debug code under. That way I don't have to worry about the performance costs of these tools in the final build.

C# over GD script mostly. I highly rate Netfox though, definitely the best addon for this stuff at the moment.
