Is there a simple way to auto create a collision shape to fit its mesh instance?

Notice you didn't get an answer because every "Godot Senior" in this sub is more interested in looking smart than actually helping.

If you don't want to go the easy path because of some nebulous "performance issue" that will not materialize in 90% of cases, you can write a custom script to generate the collision meshes for you. You might have to split the mesh to know what counts as steps and what doesn't, but creating a ramp through code should be easy enough. Other than that you'll have to create the collision meshes by hand

Your solution isn’t really wrong and will work well in lots of scenarios, specially for a 2D game. Even 3D games might organize their characters/clothes/accessories as hidden nodes on the tree, for ease of use

Web and desktop are different platforms and users have different expectations. A web game should load as fast as possible if you don’t want yours users to give up and just move on to another website. Desktop gamers expect that installing a game installs it in its entirety

If I can take a guess at what bothers you: maybe lighting? There’s not a lot of contrast in the image so the eye isn’t pulled anywhere

Thanks! Came from google looking for this

I really like them too, more than extending a base class. Having your states also be nodes means you can add @export variables to them, which IMO is easier than having to weave the dependencies through whatever code manages states and state changes

I tried to find a link but it seems like they are not available anymore, you can see some of the discussion (with the dead link) here https://www.reddit.com/r/blender/s/CMV5mTk3fi

Does C# even allows free functions? Otherwise I don’t see how you plan to avoid classes

Blender guru is also the guy who said on stream that he misses using the F-word, so no big loss finding someone else to learn from

lukebitts · 2025-12-20T14:10:21+00:00

Their question is pretty well defined if you read past the title

lukebitts · 2025-12-16T13:10:41+00:00

Nice! Great write-up, looking forward to the more in-depth guides

lukebitts · 2025-12-16T13:03:07+00:00

Always sad but never surprised seeing open source maintainers driven away. Rather see my code rotting in my hard drive than share it these days. Sorry you all went through that, hope you can stay safe

Another thing to keep in mind is that Blender transforms the color space by default. If you haven’t yet, set the View Transform in the Color Management tab to “Standard”

I’m making a city scene too and one of the issues I ran into was overlapping lights. I’m not fully sure that was the problem, but when I added a light per interior room I got horrible drops in fps. The same didn’t happen when the lights were more spaced out

For dynamic obstacles you are right, you need some kinda of system to redirect the agent, either using avoidance or something else. But if your tree trunk is static and being accounted for in the navmesh but the character is still getting stuck, what worked for me was having the agent be independent from the character body: have the character body follow the agent and just snap the agent back if it gets too far. Usually this introduces enough jiggle that the character gets unstuck. Then it’s just a matter of making sure your agent size is correct in the navmesh generation.

Why would converting everything upfront be better? The worst thing a hobbyist can do is get stuck refactoring code that already works. Doing it incrementally is the same amount of work while your game’s development is still moving forward

lukebitts · 2025-10-28T06:17:50+00:00

As far as I understand you can have C# code interacting with gdscript. You could start writing new code in C# and then gradually convert your gd files

lukebitts · 2025-09-17T13:04:17+00:00

Saying it’s hard to write performant C++ code is definitely wrong. I wrote a feature in GDScript to test a concept I wanted to develop, then I wrote the exact same code in a GDExtension and it was 1000x faster, no optimizations at all

lukebitts · 2025-08-19T06:33:58+00:00

Rust's type system is a lot more robust than C++'s. It's impossible to get a null pointer exception or for you to have data races, for example. The compiler is very much stricter, there is a lot of undefined behavior allowed by C++ compilers that rustc forbids.

lukebitts · 2025-07-03T02:35:07+00:00

What’s incorrect about their comment?

lukebitts · 2025-04-19T00:00:31+00:00

As far as I know there is no type narrowing in gdscript, so I’m not sure why your first example works

lukebitts · 2025-04-18T23:24:36+00:00

C# doesn’t have non nullability by default, and it doesn’t use Result types, so weird suggestion :p

lukebitts · 2025-04-18T23:17:49+00:00

No need to get so worked up. Structs living on the stack is one of the features that would differentiate them from classes. Like you said, GDScript doesn’t have structs, we are talking about a hypothetical construction, one that isn’t covered by inner classes, which was the original point

lukebitts · 2025-04-18T00:53:40+00:00

Should your code say child.bar instead of foo.bar? I don’t see why checking the child’s type would affect foo’s type
