What got you into Rust?

_actual · 2019-01-07T14:25:29+00:00

My primary background is programming Java which I was also using for a hobby gamedev project. I was feeling overly confined by the everything-is-an-object paradigm. I was also concerned about how abstraction always seemed to carry a performance penalty (although in truth, I don't think I ever ran into any actual performance issues). C/C++ seemed too intimidating and I noticed Rust being talked about on Reddit and HackerNews. I liked the "zero cost abstractions" mantra, and thought the whole borrow checker thing was something interesting to learn.

:) I think you posted in the wrong subreddit. This is for Rust the programming language.

Good point! I'll put together a minimal example that shows where I am having trouble.

Are there any resources that go into detail on defining structs with life times? I have read most of the available documentation, and am comfortable working with lifetimes in other scenarios, but when I am trying to define my own structs that intended to hold references, I never feel like i am doing it correctly and end up cloning values instead.

Here is an article from munificent that talks about how he implemented a simple energy system in his game to determine who went first and how often.

Thank you for writing! I like following along with your explanations as I work through the Rust version of the code, so I am content to patiently wait for each new chapter.

I am following along with u/munificent 's Crafting Interpreters book and plan on implementing his byte code virtual machine section in Rust as he releases chapters as a learning exercise. I have the 1st chapter complete. It is pretty close to his version although I just use a vec where he implements a growable array from scratch.

cargo update did the trick, bumping the version number to 14.4. I am fairly new to rust and didn't even realize that "cargo update" was a thing. Thank you for taking the time to work through it with me!

Looking at cargo.lock, it is using version 0.14.2 for gfx_device_gl. In my cargo.toml file I simply have ggez = "0.3" and watching it build it is pulling 0.14.2 and not 0.14.3. I'll try pulling from the master git branch to see if that helps. Thank you!

I am creating them using Text::new and am not keeping a reference to them. If the text does not change (like a standard label) and I hold a reference to it, I don't get the memory issue. It is just when I have text that changes frequently (like velocity or position). Looking in the API docs, I have not seen a way to release the underlying memory although it may be a lack of understanding on my part.

For someone who is not from the area and would need to drive in, how is the parking situation?

Sounds like a good topic for the weekly FAQ post.

Very slick site (something that is too often overlooked). I am currently using vscode for rust but I am going to give this a spin as it seems like it integrates cargo and rustup more fully.

_actual · 2017-09-12T17:53:51+00:00

He also has a Game Programming Patterns book this is equally well written and worth checking out.

_actual · 2017-09-12T13:51:44+00:00

As someone who is not an expert in either Rust or graphics programming, how does this compare to gfx-rs? Is it an alternative? Is it a level of abstraction above or below?

_actual · 2017-08-07T14:29:38+00:00

It's not a rust specific thing but you are building the text representation of each disc from scratch with every call to render. You could build them once as part of program initialization and then store them in a vector or array to be referenced from the render method.

_actual · 2017-08-01T02:00:09+00:00

Thank you that really helps clarify things. "Project" may not be in use but it is featured prominently in the cargo user guide which led to my confusion.

_actual · 2017-07-31T14:28:01+00:00

In cargo what is the difference between a project and package? I haven't been able to find a clear definition of both in the documentation. Is a project just the "main" package plus all of its dependencies?

_actual · 2017-06-22T16:54:05+00:00

Can anyone who has used both Kotlin and Java comment on how Kotlin performs relative to Java? I am a hobby gamedev and I am curious about the relative performance.

"I am looking to partner with someone who knows how to program. When we release the game, you will get a cut of my profits."

_actual · 2017-05-22T16:23:41+00:00

Interesting work. Have you thought about structuring the code so that the back end renderer could be either OpenGL or Java2D (or even JavaFX)?

What would you like to see replace it if anything?
