This library is useful if you are building a game prototype with Vulkano and want a quick way to add basic text rendering:
- You can only use the DejaVu font
- The text is rendered on top of the contents of your swapchain image (no depthbuffer or draw ordering)
Below are relevant lines taken from the triangle.rs example.
Import the library:
extern crate vulkano_text;
use vulkano_text::{DrawText, DrawTextTrait};
Create DrawText:
let mut draw_text = DrawText::new(device.clone(), queue.clone(), swapchain.clone(), &images);
Specify text to draw by calling queue_text:
draw_text.queue_text(200.0, 50.0, 20.0, [1.0, 1.0, 1.0, 1.0], "The quick brown fox jumps over the lazy dog.");
draw_text.queue_text(20.0, 200.0, 190.0, [0.0, 1.0, 1.0, 1.0], "Hello world!");
draw_text.queue_text(x, 350.0, 70.0, [0.51, 0.6, 0.74, 1.0], "Lenny: ( ͡° ͜ʖ ͡°)");
draw_text.queue_text(50.0, 350.0, 70.0, [1.0, 1.0, 1.0, 1.0], "Overlap");
Call draw_text on the AutoCommandBufferBuilder after your game render pass:
.draw_text(&mut draw_text, image_num)
You will also need to recreate DrawText when you recreate your swapchain e.g. due to window resize
