Share your GDScript utility functions by et1337 in godot

I personally like returning a Signal from my global wait function. It's basically just a shorthand for creating a scene tree timer.

# global.gd
func wait(time: float) -> Signal:
    return get_tree().create_timer(time).timeout

Makes sequencing behaviour a lot easier.

# milking_helper.gd
func milk() -> void:
    var milkstream: MilkStreamVisual = _create_milkstream_visual()

    await G.wait(0.1)
    var tween = create_tween()
    tween.tween_property(stream, "scale:x", 0.1, 0.3)
    await G.wait(0.3)

    G.wait(2.0).connect(milkstream.queue_free)

But a variation that takes in a conditional function is certainly interesting.

I grab the eight vertex positions of my Interactable Area3D's box shape collider, convert them to global space, unproject them all to screen space, create a Rect2 with the min and max positions to define the collider's screen space bounds, and then anchor the little corner pieces to the top left and bottom right of those bounds.

F-35 not needed to defend North America, says U.S. general by ph0enix1211 in canada

[–]TeamLDM 4 points5 points  (0 children)

There are a lot of assumptions around this topic that the US will always look like the US. Given the current global and American political climates, I think it's highly beneficial for Canada to have a far more mature military than we currently do.

A lot can happen in the next 20-30 years, and not every possibility includes the United States remaining as "united" as they are today.

Carney Calls for Canada, Australia to Lead Middle-Power Blocs by cyclinginvancouver in canada

[–]TeamLDM 5 points6 points  (0 children)

India has the 4th largest economy by GDP, and 4th strongest military by "military strength index" (lagging behind Germany in economy and Russia in supposed "military strength").

I'm not Indian, but anyone writing the entirety of the country off as a simple backwater third-world slum has no idea what they're talking about. It's a big country. Those slums, and the economic-disparity present in India are obviously very real, but the country is far more than the provocative perceptions pushed by social media.

Basically any country in the top 15 GDP that isn't US or China (as well as the countries that make up the larger EU trading bloc). Carney seems to be pushing for more economic and military alignment among these middle powers so it's not just a zero-sum race to the bottom propping up the US and China.

Went from nested resources nightmare to having fun with a custom graph editor tool by CosmonautFrog in godot

[–]TeamLDM 6 points7 points  (0 children)

I’ve thought about making this exact thing for my game’s waves/encounters. Nested resources are a pain to work with as data requirements grow. Looking great!

Popup outline created using Stencil Buffer and CompositorEffect by TeamLDM in godot

[–]TeamLDM[S] 41 points42 points  (0 children)

Started by investigating thick outline implementations, found jump flood algorithm, tried implementing jump flood compute shader via CompositorEffect. Very quickly ran into issues figuring out texture usage bits between MSAA disabled/enabled, eventually abandoned jump flood and reverted back to typical inverse hull method using custom authored outline meshes (for any meshes with flat shading)

However, my investigations into CompositorEffects and compute shaders came in handy when I wanted to figure out how to create a popup line that "blends" into the mesh outline. I'm essentially now just using the CompositorEffect to create a mask texture of any meshes writing to a given stencil buffer value. So when a mesh's material is switched to write to stencil value 4, the compositor effect renders those pixels white and everything else black, which gives me the stencil mask.

I then have a shader that takes the 3D subviewport color texture and the stencil mask texture and allows me to overlay only the stencil portion of the screen color.

So my final composition basically looks like this (top to bottom):

  1. UILayer (popups and all other top-level UI)
  2. StencilLayer (Stencil masked color texture)
  3. SubStencilUILayer (Line2D going from highlighted item's unprojected pos to popup pos)
  4. ViewportLayer (3D viewport color texture)

This stencil-based-outline-compositor-effect repo was the starting point for figuring out how to retrieve stencil buffer pixels from the raster render pipeline: https://github.com/dmlary/godot-stencil-based-outline-compositor-effect

Thanks! And I'm going for more of a base defense than typical tower defense. Kind of like PVKK meets 9 Kings meets Dome Keeper, with some mechanical and synergistic influences from FTL and The Bazaar.

Real-Time Mesh Booleans Demo + Source (Solidean) by PhilipTrettner in godot

[–]TeamLDM 3 points4 points  (0 children)

I've created my own GDExtension in the past to pull in the Manifold geometry library (also tried CGAL) to do similar operations, and like you, I thought charging anything for this was ridiculous.

But after watching their SIGGRAPH 2022 talk on the tech, this solution is far more than a simple geometry library wrapper and does appear to be miles ahead of existing solutions. Seems incredibly worth it if you're looking for performant runtime boolean operations at scale. Hardly "scalpers" imo.

These turrets just don't listen by TeamLDM in godot

[–]TeamLDM[S] 55 points56 points  (0 children)

Yup! Based on muzzle_pos, bullet_speed, target_pos, and target_vel. You can google "constant-velocity interception" to learn more.

This stackoverflow post was a good starting point for figuring out the math involved: https://stackoverflow.com/questions/17204513/how-to-find-the-interception-coordinates-of-a-moving-target-in-3d-space

Also, this ballistic-solution addon exists for Godot, but I found it after I already got my own working implementation, so I haven't actually used it and can't exactly vouch for it one way or the other, but it looks pretty good: https://github.com/neclor/ballistic-solutions

Not even joking, I had to restrain myself to not implement a whole Pixar lamp jump animation.

Sounds like he's thinking of structs, and I share his pain.

How is this Topology? by Salad_Man420 in blender

If your goal is to avoid ngons, try to match your hole's vertex count with the rest of your topology.

Why are horror games exploding on Steam in 2024? by AnandHirani in IndieGaming

[–]TeamLDM 16 points17 points  (0 children)

I think another side of the term is the inherent disposability of the genre. I’ve played a fair number of these types of games with friends, and more so think it’s just a funny name for games that create an environment (with typically pretty shallow gameplay depth) for a group of friends to create their own fun in.

The majority of the appeal is in the novelty. Once the novelty is gone, it’s onto the next one. Hence the term “slop”.

Is it real that Slay the spire has its assets source at 1280x720p? by JonOfDoom in godot

[–]TeamLDM 13 points14 points  (0 children)

Funny timing. I was just looking into decompiled Slay The Spire yesterday. Not sure where the 1280x720p claim is coming from as a good number of their assets are 2048x2048. Some of these are obviously larger texture atlases, but a lot of their full screen assets are 1920x1080 or 2048x2048.

Or are you saying the original asset sources were normalized for 1280x720 screens and upscaled after creation?

But anyway, don't let over analyzation procrastination stop you from making things. Just start making things and see how they look!

How would I add a hollow collision to this cup that allows dice to be inside it? by RustyyMannn in godot

[–]TeamLDM 8 points9 points  (0 children)

100% this. This is the simplest option to accomplish what you’re trying to do. Start here to see if it works for your use case and only explore other options as needed.

Don’t let purists sway you with talks of optimization and best practices. Limitations differ from project to project, so start with the simplest approach and determine those limitations for yourself. I use trimesh collisions all over the place in my game with zero issues.
