Panic in quad_gl on breaking the game loop
Hi! Thanks for providing Macroquad. I have had a lot of fun with it he last few days.
I run into a strange panic issue when exiting the game loop after having rendered a glsl shader pair. I may be holding it wrong, but anyway. This is the smallest reproduction I can figure out how to make:
use macroquad::prelude::*;
const FRAGMENT_SHADER: &str = "#version 100
void main() { }
";
const VERTEX_SHADER: &str = "#version 100
void main() { }
";
#[macroquad::main("¡Viva la libertad, CARAJO!")]
async fn main() {
let render_target = render_target(320, 150);
let material = load_material(
ShaderSource::Glsl {
vertex: VERTEX_SHADER,
fragment: FRAGMENT_SHADER,
},
MaterialParams {
..Default::default()
},
)
.unwrap();
loop {
clear_background(BLACK);
gl_use_material(&material);
draw_texture_ex(
&render_target.texture,
0.,
0.,
WHITE,
DrawTextureParams {
dest_size: Some(vec2(screen_width(), screen_height())),
..Default::default()
},
);
gl_use_default_material();
if is_key_pressed(KeyCode::Escape) {
break;
}
next_frame().await;
}
}
It seems to matter if I call draw_texture_ex() or not, because removing it, I do not get the panic.
To check that it is happening on latest macroquad. I'm using a freshly cloned local repo with master checked out.
To reproduce
-
cargo run - Press
escape
- Expected: The program exits cleanly
-
Actual: There's a panic:
thread 'main' panicked at /Users/pez/Projects/macroquad/src/quad_gl.rs:581:40: called `Option::unwrap()` on a `None` value
