Does anyone think Mojo could be great for Game Development?

The problem is that GPUs still have a bunch of fixed function hardware for certain parts of the graphics pipeline that isn't usable with GPGPU tools. I would love to see Mojo support that somehow in the future but right now a shader based rendering approach will have significantly worse performance than a proper graphics API. I just started playing around with some vulkan bindings the other night. Will let everyone know if I come up with a nice to use interface because yeah, it's definitely "C programmer brained" in its design

mo3d: 3D library for Mojo

Nice! You may also want to check out these sdl bindings as they're a little bit more up to date than msteele's (I also found theirs very helpful for getting started) https://github.com/Ryul0rd/sdl-bindings

I don't think there is natively but there must be a way to do it in C so you could use C bindings

Does anyone think Mojo could be great for Game Development?

yeah, Mojo also appealed to me as "python but I can just ship a binary like a real language"

Does anyone think Mojo could be great for Game Development?

If large studios do start adopting it it probably wouldn't be through unity/unreal. Apparently there have already been 1 or 2 big studios that made in house engines in Rust so I imagine something similar would happen if Mojo became popular in AAA

Does anyone think Mojo could be great for Game Development?

just because unreal and unity are the big two engines doesn't mean they need to adopt mojo for it to see success. It could be adopted by Godot (seems very likely even due to their plugin system) which is getting more popular, there could be a new engine written from scratch in Mojo that gets popular, or there could be a new engine written from scratch in Mojo that never gets popular but is still a good engine that is worth using (popular != good)

Just learn Mojo?

If you're trying to land a job or even just be productive Python is very much still the way to go for now. If you're just trying to learn though building everything from scratch in Mojo is a great way to do that

How to random int ??

var a: UInt32 = 42
var b = int(a)

var a: UInt32 = 42
var b = int(a)

Scalar types like UInt32 are just aliases for simd types like SIMD[DType.uint32, 1]

yeah this would also work

I was looking into doing this but the sdl bindings currently use mojo nightly and magic doesn't support nightly yet. Definitely going to try to get that working once next stable drops

Reading from stdin

have you considered making a PR to get this in the standard lib? We really should have input

That is consistent with the issues we were running into. Does this means that all bindings will have to live inside of a struct instance? The ergonomics there aren't great. Static linking or proper global dynamic linking would be nice to have

Is this broken or is it me? Parameterized function alias...

You can't parameterize a runtime value. Parameterization means the compiler actually makes a specialized version of the thing and so it needs to happen at compile time.

Is this broken or is it me? Parameterized function alias...

You can parametrize just a function but having a method and a field on a struct both parameterized in the same way requires you to parameterize the struct. It's not clear to me why you need the struct without knowing more about the use case but you might be better off with just a function

also you forgot to cast from Int32 to UInt8

Is this broken or is it me? Parameterized function alias...

This works:

fn example_fn_1[X: Int](default: Int32) -> SIMD[DType.uint8, X]:
    return SIMD[DType.uint8, X](default.cast[DType.uint8]())


struct ExampleStruct[L: Int]:
    var example_fn: fn(Int32) -> SIMD[DType.uint8, L]

    fn __init__(inout self):
        self.example_fn = example_fn_1[L]

    fn make_buffer_ok(inout self, default: Int32) -> SIMD[DType.uint8, L]:
        return example_fn_1[L](default)

    fn make_buffer_sad(inout self, default: Int32) -> SIMD[DType.uint8, L]:
        return self.example_fn(default)

fn example_fn_1[X: Int](default: Int32) -> SIMD[DType.uint8, X]:
    return SIMD[DType.uint8, X](default.cast[DType.uint8]())


struct ExampleStruct[L: Int]:
    var example_fn: fn(Int32) -> SIMD[DType.uint8, L]

    fn __init__(inout self):
        self.example_fn = example_fn_1[L]

    fn make_buffer_ok(inout self, default: Int32) -> SIMD[DType.uint8, L]:
        return example_fn_1[L](default)

    fn make_buffer_sad(inout self, default: Int32) -> SIMD[DType.uint8, L]:
        return self.example_fn(default)

There were a couple problems. 1. It looks like like you can't parameterize a parametric function pointer type in an alias. Not sure why though. 2. Your struct needed to be parameterized at the struct level so it knows that the different parts are parameterized in the same way.

MLIR Docs

yeah I guess it being considered part of the compiler or not is just semantics and not irrelevant. It's just a case of if Modular wants to document it or not and why. You can kinda figure out bits of what's going on through error messages and things so I doubt they consider it a well guarded secret the way the would with other stuff they haven't opened up

MLIR Docs

There have been statements in the past like (paraphrasing) "things you'd normally need a compiler engineer for in Mojo you can just have an ordinary programmer do because you can just write inline MLIR". Statements like this seem odd if the MLIR you need to use is really part of the compiler
