Piston Examples

A collection of examples using the Piston game engine

How to contribute

How to build & run examples

To build the examples, you need Rust and Cargo installed.

Install Rustlang for example through rustup
Invoke cargo run --example <NAME> where the NAME are a file names from examples directory 2.1. Optionally navigate to examples/<directory> and invoke cargo run for more complex examples

Troubleshooting

I get ld: library not found for -lSDL2 error on OSX
I get "GL context creation failed" when running an example.

It's likely your hardware or driver doesn't support PistonWindow's default OpenGl spec. Just change it to something you can support at the beginning of the example. See hello_world.rs for an example.

piston-examples's Issues

Add gfx_cube example

Should be based on https://raw.githubusercontent.com/gfx-rs/gfx-rs/master/src/examples/cube/main.rs

examples builds are not passing

~~looking at the travis build confirms this.~~ an example of the issue:

[deform]$ cargo run

error: aborting due to 5 previous errors
Could not compile `deform`.

Add gfx_cube back in

One thing I didn't thought about, was that gfx-rs needs to be initialized slighty different under Piston by calling let (mut device, frame) = window.gfx();.

Remove unused 'readme' flag from Cargo.toml

I am trying to run the image example on ubuntu 14.04.1. I have intel integrated graphics, and am running the i3 window manager. I downloaded cargo and rust from nightly repos this morning, and after installing some dependencies everything seems to build fine. When I run "cargo run", the screen flickers and I get an error:

awagner@ash:/home/awagner/src/rust/piston-examples/image
$ cargo run
     Running `target/piston-example-image`
task '<main>' panicked at 'called `Result::unwrap()` on an `Err` value: Could not create GL context', /home/rustbuild/src/rust-buildbot/slave/nightly-linux/build/src/libcore/result.rs:787
An unknown error occurred

Any ideas? Thanks!

Update dependencies for deform

Since the drag controller has been moved into his own repo we need to update the dependencies in Cargo.toml

Travis CI failing because rust-sdl2_mixer points to old version on crates.io

Just posting this here so you don't need to read through the logs.

The music example fails to build because rust-sdl2_mixer points to an old version of rust-sdl2 on crates.io. To fix this problem I suggested earlier to sdl2 to the git (also to keep effects of breaking changes more managable).

Waiting for andelf/rust-sdl2_mixer#18

Create an example drawing a triangle with gfx-rs

This should show how to combine Piston and gfx-rs.

Add camera navigation to gfx_cube

Can use the new camera features in Piston.

Investigate why 'user_input' example is not working

This happens on my machine, but I don't have time to check it closer at the moment.

Probably something to do with the GLFW back-end.

Add deform example

Should demonstrate how to use DeformGrid and how to draw a deformed image.

Can use the logo of Rust.

"gfx_cube" example not showing anything

rustc 1.0.0-nightly (d3732a12e 2015-02-06 23:30:17 +0000)

Remove hgl_triangle

hgl is deprecated and will be replaced by gfx-rs.

Remove "music" example

This has been broken for a while and can be added back when sdl2_mixer gets updated.

Camera controller is very sensitive

Something is wrong with the gfx_cube example.

All examples: Could not compile `shader_version`.

I have tried desperately to use this game engine for 10 days now. I might just use C++, but I wanna use rust :(

I originally put this problem on a separate issue, PistonDevelopers/Piston-Tutorials#61, but I wasn't sure if it should have been a new issue instead.

Add instructions of how to build examples to README

How to build & run examples

Install Cargo
In the Terminal window, navigate to the project directory of the example you want to build.
Type cargo build
Type make run

Check that SDL2 does not send repeated key up events

See PistonDevelopers/sdl2_window#99

It might be a possibility that SDL2 sends key up with repeated events and that this gets filtered out by sdl2_window.

Use the user_input example to test:

Press a key for several seconds
Release the key
Check that key up is triggered as normal

Use "user_input" as test for window back-ends

See PistonDevelopers/conrod#326

Make it easier to change window back-end by using features

Draw a miniature illustration of the frame buffer vs the inner window space

The inner window space should be on the left, the frame buffer on the right
The mouse coordinates should be displayed in window rectangle

As you move the mouse around in the inner window space, the mouse cursor position displayed in the illustration should correspond to the actual position. My moving the cursor from the upper left corner and down to the right corner, one can test if the position is correct.

Testing Glutin back-end with "user_input"

Running the "user_input" example https://github.com/PistonDevelopers/piston-examples/blob/master/user_input/src/main.rs

On OSX 10.9.5, I get this with Glutin:

SDL2:

Example gfx_cube: gfx::Frame has no function "new".

Hey all,

After trying to build gfx_cube, I receive this error:

[andre@localhost gfx_cube]$ cargo build
Compiling piston-example-gfx_cube v0.0.0 (file:///home/andre/Workspace/rust/piston-examples/gfx_cube)
src/main.rs:107:17: 107:32 error: type `gfx::render::target::Frame<_>` does not implement any method in scope named `new`
src/main.rs:107     let frame = gfx::Frame::new(win_width as u16, win_height as u16);
                                ^~~~~~~~~~~~~~~
error: aborting due to previous error
Could not compile `piston-example-gfx_cube`.

I was reading through the gfx source and it looks like empty() should be being called:
https://github.com/gfx-rs/gfx-rs/blob/master/src/render/target.rs

I tried changing the code from:
let frame = gfx::Frame::new(win_width as u16, win_height as u16);

to:
let frame = gfx::Frame::empty(win_width as u16, win_height as u16);

Then ran cargo build again. It compiled without issues.
However, it gives this when running:

[andre@localhost gfx_cube]$ cargo build
Compiling piston-example-gfx_cube v0.0.0 (file:///home/andre/Workspace/rust/piston-examples/gfx_cube)
[andre@localhost gfx_cube]$ cargo run

An unknown error occurred

I don't think I know enough about Rust yet to see the problem. Why is the assertion failing? I don't see where the issue is stemming from. Excited to learn though :)

If I am doing anything wrong (or right) in submitting an issue this way please let me know. I'm pretty new to github, open source projects, and Rust, so tips/tricks/advice is more than appreciated. Thanks!

Upgrade "gfx_cube" example to latest Gfx

gfx_cube and paint examples failing

The version of gfx they're using doesn't work with the latest rustc nightly. Investigating now.

Error when compiling sprite example

src/main.rs:1:1: 1:1 error: reached the recursion limit during monomorphization

              ^

Why Piston-Examples don't use lockfiles

See #72

Cargo.lock is a file that makes cargo build use the same dependencies, which is useful when you want to run programs with older versions of libraries.

piston-examples is specifically meant to display examples of how to use the latest version of piston.

For this reason, we put Cargo.lock in .gitignore per example to prevent tracking them, such that we are forced to keep the examples up to date.

Add note to README that latest Rust nightly and Cargo is required

examples do not compile

Hey guys, I've been looking to start learning rust by creating small project for fun and found this awesome GUI library, but unfortunately examples do not compile..

first error which I get is:

all_widgets.rs:48:5: 48:11 error: unresolved import event::Render. There is no Render in event

I did some investigation and I think Render was renamed to RenderEvent(given that I have really poor rust knowledge) but I'm not sure how to really fix this..

Mismatched types

When I try to build any of the examples I get two types of errors. The first is mismatched types, and the second is that a trait is not implemented for the open_gl library. I've attached a screen shot of the errors. This could be an error with my machine, but I'm too new to Rust to really know.

Create an example using Rust-Image with textures

How to manipulate a RGBA image and update a texture in real time.

This might require updates to opengl_graphics.

Add scissor/stencil/blending example

This could be used to test different draw states when the back-ends supports this.

Move over assets from gfx_graphics

These belongs to the gfx_graphics examples https://github.com/PistonDevelopers/gfx_graphics/tree/master/assets

Remove gfx_cube and gfx_triangle

These are almost identical to the examples in the gfx-rs repo. The effort of keeping those up to date with gfx-rs (which is currently very unstable) can be put into gfx-rs instead.

Translate deform example to use the piston repo

I think the the high level library is at a state where it needs more widespread testing. See PistonDevelopers/piston#780

Start with translating one example, choosing "deform".

Add capture cursor to `user_input` example

Could be activated when pressing C or something.

Add "hello world!" example

Should load font from assets folder and display a text "hello world!" with PistonWindow.

Add example with playing music

Could use rust-sdl2_mixer.

Remove piston dependency from examples

It is recommended to use the libraries directly.

Add lockfiles ?

According to http://crates.io/faq.html#why-do-binaries-have-cargo.lock-in-version-control,-but-not-libraries? the convention is to checkin lockfiles for executables.

If we check in lockfiles for each of these examples then the only thing we have to worry about breaking builds is breaking changes from the nightlies. On the other hand fixing versions for Piston dependencies will likely lead to examples getting out of date.

I'm leaning towards adding them.

But I can't run the getting-started example.

I changed OpenGL::_3_2 to OpenGL::_2_1:

    let mut app = App {
        gl: GlGraphics::new(OpenGL::_2_1),
        rotation: 0.0
    };
