Is there a macroquad-included way to play sound on all the given platforms, or is there a library that should be used that would work on all platforms with macroquad?

• set_default_camera and actual default camera are different. How to test: draw stuff without any set_whatever_camera calls and than add set_default_camera on top. The results should be the same

• make it clear how to create Camera2D with exactly the same params as set_default_camera. Maybe just add the params of that Camera2D to docs of set_default_camera

Miniquad itself has RenderPasses for rendering to a texture for post-processing or other. I have thus far not been able to figure out any way to accomplish something like this with macroquad. Is there a way I have just overlooked, or is this simply not implemented yet?

There seems to be no way of matching an error in something like:

match load_file(path).await { ... }

I cloned repository and tried run 3d example with command:

cargo run --example 3d --release

After compile I got this error:

I feel like I must be doing something wrong.

Cargo refuses to build a binary with cargo build --target wasm32-unknown-unknown.

I can build as a library instead, then I get an error about main not being exported when I try to load the library in html.

I can fix that error by applying the following patch, which works fine, but I don't understand how anyone is using this library as-is. What might I be doing wrong/differently?

From drawing.rs:215:

let vertices = [
            Vertex::new(x    , y    , 0., sx     , sy     , color),
            Vertex::new(x + w, y    , 0., sx + sw, sy     , color),
            Vertex::new(x + w, y + h, 0., sx + sw, sy + sh, color),
            Vertex::new(x    , y + h, 0., sx     , sy + sh, color),
        ];

For simplicity, let us say we are always drawing to location (0,0) from a source rectangle with origin also at (0,0). Our free parameters are 'w', 'h', 'sw', and 'sh'.

If we are drawing a 128x128 sample at 'real' size, we set w=128, h=128, sw=128, sh=128. Unfortunately, while the destination rectangle has the correct size (verts have 128 added for w and h), the source rectangle has UVs at (0,0), (128,0), (128, 128), (0, 128). Instead, we should divide the UVs by the texture width and texture height.

Would be useful to have some call to request to quit the app (so close the program on desktops, exit application on mobile, stop processing on the web, etc...).

I'm trying to get a first person 3D camera to work. Currently, I can successfully fly around the world and look using the mouse.

However, when the mouse reaches the edge of the screen, it hits the edge and no longer gives any mouse position information.

There are 2 ways to solve this that I can see:

1. Keep sending mouse events when mouse is outside the window.
2. Allow the user to set the mouse position so they can control wrapping the mouse when it goes outside the window.

I don't know if Sokol uses GLFW but in Raylib (GLFW), I have this same problem on Linux. Not quite sure how to solve it without a way to set the cursor position.

Note: I have used the ctx.set_cursor_grab(true) and ctx.show_mouse(false) functions and it doesn't change the above behavior.

Alternatively, if another 3D example could be created that tests the mouse look and screen border interaction that would be amazing.

Here is what I've got so far for reference:

        next_frame().await
    }
}

Can an example be created or could someone point me in the right direction to be able to render a list of vertices/texcoords without a custom pipeline/shader? I'd like to use it like the other draw_...() functions if possible.

The goal here being to generate geometry in-game and then render it, but I don't need anything fancy (just textures).

I'd like to set the filter mode for a texture:

texture.set_filter(&mut get_context(), FilterMode::Nearest);

Unfortunately, the get_context() function is private. How do I get the current context in order to use the functions that require it?

Сan i set the window size? and can i forbid changing it?

close_button not working without titlebar:

            WindowParams {
                titlebar: false,
                close_button: true,
                movable: false,
                ..Default::default()
            }

I really like the miniquad's event-based input with impl EventHandler for Stage because it allows the input to be independent from FPS. For example: input from touch can come 100 times per second even if draw happens at 30 FPS on mobile.

In macroquad's examples currently the input is polled on each frame (example: is_key_down), which makes the input rate tied to the framerate. This would be a problem for apps that rely on high-frequency input, example: painting apps or Fruit Ninja-like games, because the lines a person draws with their finger will miss some input data that changes in between frames. On phone, the input rate reported from the screen is typically 100 FPS, while games run at 30-60 FPS.

I propose to have a way to handle events in macroquad independent of the framerate in a similar way it's done in miniquad.

What is your opinion?

https://docs.rs/macroquad/0.2.9/macroquad/fn.draw_circle_lines.html

So I am using draw_circle_lines() function using the macroquad crate and for some reason it displays this ugly blank dots where you can see the background. Here is my code to draw this (only for the draw_circle_line() function)

draw_circle_lines(screen_width()/2., screen_height()/2, 30, 20., RED);

I just ran the Arkanoid example and saw that the "Press space to start" text wasn't working:

I have narrowed down the cause to be somewhere between 0.3.0-alpha.2 and 0.3.0-alpha.4:

• 0.3.0-alpha.2: the example displays the text correctly
• 0.3.0-alpha.3: the text is completely gone
• 0.3.0-alpha.4 onward: the example looks like the above image

I compiled using rustc 1.49.0 on a Windows 10 laptop with an Intel UHD 620.

The Cargo.toml file currently has a dependency on a copy of megaui in ../megaui. Prevents running or building with macroquad.

I see that miniquad has the ability to toggle mouse visibility (https://docs.rs/miniquad/0.2.55/miniquad/graphics/struct.Context.html#method.show_mouse), but it doesn't look like that API is available in macroquad.

It would be amazing to have a WASM (and native) game work with a game controller! 🎮

I'm currently learning Macroquad while I finish a project started with a different library.

I'm actively interested in any new (even cutting edge) features of Macroquad.

Could a roadmap be appended to the README that just says what you're currently working toward feature-wise?

Hi where can I find the documentation for macroquad?

I wanted to suggest to add ECS as present with Ameythist and Bevy to improve performance.

I got the docs from here: https://docs.rs/macroquad/0.3.0-alpha.14/macroquad/index.html I'm using Macroquad 0.2.9.

I am using Elive Linux 3.8.17. My Cargo.toml looks like this:

[package]
name = "musicmania"
version = "0.0.1"
authors = ["TheTechRobo"]
edition = "2018"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
macroquad = "^0.2.9"
[profile.dev.package.'*']
opt-level = 3

Here is the error:

}

Any help would be appreciated. I'm still new to Rust. I'll try changing the example code.

• get_fps should probably return FPS over some period of time (or number of frames) - that way, it would report a stable 60 on 60 FPS screens if the game runs fast enough, otherwise it would show less and it would be obvious that frames are dropped. Note i tried several methods of calculating the average, some of them produce numbers like 59.9 or 60.1. I found that saving n timestamps, then using (first - last) / (n - 1) works well (e.g. https://github.com/martin-t/rec-wars/blob/6a04b5f5b7191bbc3ccea95c0a7886a05f761f04/src/timing.rs#L5).

• I find the name get_frame_time misleading. I updated the docs (#133) but i think it should be renamed to get_frame_duration. Time to me implies a point in time, duration implies how long something took. I think this potential for confusion is even more apparent here: Context::start_time and Context::last_frame_time are points in time vs Context::frame_time is duration.

• I would like a way to measure how much time was spent rendering. My understanding of macroquad is that the draw calls in main just queue up what's to be rendered but the actual rendering happens after calling next_frame().await. Is that correct? In that case there's no way to measure time spend rendering from game code.

With z_index we will be able to set which objects are going to be rendered behind others and etc.
Adding a z_index in DrawTextureParams to be used with draw_texture_ex seems ideal.

Not sure if this is megaui or macroquad. If I make the label one character shorter, the text renders, otherwise it doesn't.

This is with web assembly and chrome.

use macroquad::{self as mq, hash};
use megaui::{self};

#[macroquad::main("TestWindow")]
async fn main() {
    loop {
        mq::clear_background(mq::BLACK);

        let window_params = mq::WindowParams {
            movable: false,
            close_button: false,
            titlebar: false,
            ..mq::WindowParams::default()
        };

        mq::set_ui_style(megaui::Style {
            window_background_focused: megaui::Color::from_rgb(0, 0, 0),
            window_background_inactive: megaui::Color::from_rgb(0, 0, 0),
            focused_text: megaui::Color::from_rgb(255, 255, 255),
            inactive_text: megaui::Color::from_rgb(255, 255, 255),
            ..megaui::Style::default()
        });

        let margin = 0.01;

        mq::draw_window(
            hash!(),
            mq::Vec2::new(mq::screen_width() * margin, mq::screen_height() * margin),
            mq::Vec2::new(
                mq::screen_width() * (1.0 - margin * 2.0),
                mq::screen_height() * 0.60,
            ),
            mq::WindowParams {
                label: "".into(),
                ..window_params
            },
            |ui| {
                ui.label(None, "what if this is really long and goes on for a long time and keeps filling up all of the room when the screen for text until no more will fitwhat if this is really long and goes on for a long time and keeps filling up all of the room when the screen for text until no more will fitwhat if this is really long and goes on for a long time and keeps filling up all of the room when the screen for text until no more will fitwhat if this is really long and goes on for a long time and keeps filling up all of the room when the screen for text until no more will fitwhat if this is really long and goes on fooooooooooooooooooooooooooooooooooooo eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee teeeeeeeeeeeeee teeeeeeeeeeeeee teeeeeeeeeeeeee teeeeeeeeeeeeee teeeeeeeeeeeeee teeeeeeeeeeeeee teeeeeeeeeeeeee teeeeeeeeeeeeee teeeeeeeeeeeeee teeeeeeeeeeeeee t");
            },
        );
        mq::next_frame().await
    }
}

At the start:

    // build camera with following coordinate system:
    // (0., 0)     .... (SCR_W, 0.)
    // (0., SCR_H) .... (SCR_W, SCR_H)
    set_camera(Camera2D {
        zoom: vec2(1. / SCR_W * 2., -1. / SCR_H * 2.),
        target: vec2(SCR_W / 2., SCR_H / 2.),
        ..Default::default()
    });

But then when text is drawn:

            draw_text(
                "Press space to start",
                screen_width() / 2. - 140.,
                screen_height() / 2.,
                30.,
                mq::BLACK,
            );

2 issues here:

• draw_text appears to be respecting the camera coordinate system, so screen_width and screen_height are way out of bounds because they are almost always greater than 20
• it also appears to be applying the coordinate transformation to the text size, not sure if this is intentional, so 30 is HUGE. I can see the text if I use:

        draw_text(
            "Press space to start",
            SCR_W / 2.,
            SCR_H / 2.,
            1.,
            mq::GREEN,
        );

I'm compiling to web assembly and viewing in Chrome in case that's relevant.

It would be nice if there was a way for me to draw text knowing that the text wouldn't be stretched or distorted at all, but I don't know how to choose the font size based on the camera parameters so that the original font pixels and the screen exactly line up?

Could not run shadertoy example.
rustc spits out this

thread 'main' panicked at 'Not such texture: rust.png', src/texture.rs:20:50

But the error message is clear and reason is obvious, so I sorted it out.
But the question remains. Would not it be better to update paths to run from the root of the crate, without going under /examples?
Totally for you to decide.
The demo is AWESOME. Especially when I am learning shaders now and able to understand how it works.

I successfully created the apk for Android. But how can I include a png into it? When I compile the example "texture.rs" on my pc at runtime it finds "ferris.png", but on Android I need to include this image into the apk (in the right path).
Maybe this is not the right place to ask, so where can I learn the stuff about making the apk? Now I simply use this command:
$ docker run --rm -v $(pwd)":/root/src" -w /root/src notfl3/cargo-apk cargo apk build --example texture

Looking into using macroquad for a WASM prototype. For some reason the WASM build seems to be failing on a missing import.

Just following the documentation, and double checked everything. gl.js which is placed online maybe outdated?

Great work on the implementation, and fundamental choices.

Sorry, I just began to use Rust for a short while. And I am trying to use your lib.
I work on Linux. I create a new project by "cargo new ... " command. I put "macroquad = "0.2.9" in the Cargo.toml. And I copied your example folder's code into mine. But from the very beginning, I received a lot of error by the compiler. Such as "can not find prelude", "can not find Conf" and etc.
I don't know what I should do. Thanks for help!

Issue:

When placed on non-integer coordinates both drawn rectangles (I suspect this applies to all shapes) and textures (in FiterMode::Nearest where it shouldn't be the case!) get visible artifacts.

Example for rectangle:

Example for a texture:

Correctly rendered texture by attaching a 1px transparent border to it:

Reproduction:

Bug can be reproduced by putting the following file in the examples folder and running cargo run --example filter_err:
https://paste.ofcode.org/MuS8ezGpuwvPg2BxM6FBRq
Additional instructions inside.
To test the version with file download these 2 additional images and put them in the examples folder:
(borderless.png)

(border.png)

Performed tests:

• rounding to integer coordinates [fixes the issue, but not a valid solution with a zoom]
• using draw_texture_ex to explicitly set the drawn area [doesn't work]
• adding border to the image and always drawing the 1px border [fixes the issue, hints at possible off-by-one error in the source code and can't be used for rectangles and other provided shapes]

Specs:

Windows 10, newest version of stable Rust, branch 0.3 of macroquad

On Desktop no problems. On the Android smartphone (touchscreen) mouse_position() gets updated only if you keep pressing your finger against the screen while moving it. If you just touch the screen without moving the position of your finger mouse_position() doesn't update, and gets the last value.
So you can't even click on a button. You can only do gestures. You can know whether you touched the screen (with is_mouse_button_down) but you don't know the position, if you just do a single tap.
But maybe I'm missing something.

When using the draw_text method, the text drawn is blurry at higher font sizes. Doe this have to do with the fact that a picture is used as a font? Is there a way to get a better looking text at higher font sizes?

When I run the texture example I get 17-19% CPU resources.
That's really high.

My machine:
Intel i7-8750H
NVIDIA GeForce GTX 1060

As reference in Discord I had a discussion about the issue and I had a report that in Linux it is around 2% and that sounds about right.

When I do cargo run --example 3d works fine, but when I try to run actuall 3d.exe from target dir, two windows pop up and instantly close.
At this moment I saw it only with 3d example, but I didn't tried all. Tree and asteroids are working fine.

Currently, you can only get the primary touch position using mouse_position().
However, most smartphones support multiple touch positions, and this feature is a must in most games.
As this feature already exists in microquad, it shouldn't be too hard to implement it in macroquad.

since touches are translated into mouse events by default we should also update the mouse position in mouse_button_down_event and co. otherwise reading the mouse_position after is_mouse_button_down is outdated.

Hi,

There's a few places where the code can panic:

Also in quad-gl:
https://github.com/not-fl3/quad-gl/blob/3e0bbc0e36fd960c4e99a611a1d94b5d4bb9523e/src/lib.rs#L573

Could it be possible to return a Result instead?
I believe there's not error type yet, so we'd need to define this first?
