hudhook

A render loop hook library with Dear ImGui overlays, largely inspired by CheatEngine.

Currently supports DirectX 9, DirectX 11, DirectX 12 and OpenGL 3.

Read up on the underlying architecture here.

Example

```rust // src/lib.rs use hudhook::hooks::dx11::ImguiDX11Hooks; use hudhook::hooks::{ImguiRenderLoop, ImguiRenderLoopFlags}; use imgui::{Condition, Window}; struct Dx11HookExample;

impl Dx11HookExample { fn new() -> Self { println!("Initializing"); hudhook::utils::alloc_console(); hudhook::utils::simplelog();

    Dx11HookExample
}

}

impl ImguiRenderLoop for Dx11HookExample { fn render(&mut self, ui: &mut imgui::Ui, : &ImguiRenderLoopFlags) { Window::new("Hello world").size([300.0, 110.0], Condition::FirstUseEver).build(ui, || { ui.text("Hello world!"); ui.text("こんにちは世界！"); ui.text("This...is...imgui-rs!"); ui.separator(); let mousepos = ui.io().mousepos; ui.text(format!("Mouse Position: ({:.1},{:.1})", mousepos[0], mouse_pos[1])); }); } }

hudhook::hudhook!(Dx11HookExample::new().into_hook::()); ```

```rust // src/main.rs use hudhook::inject; use std::process::Command;

[test]

fn testrunagainstsample() { let mut child = Command::new("mydx11application.exe") .spawn() .expect("Failed to run child process"); std::thread::sleep(std::time::Duration::frommillis(250));

inject::inject("my_dx11_application.exe", "target/release/libmycrate.dll").ok();

child.wait().expect("Child process error");

} ```
