# vrising-camera

This Python script rotates the camera in V-Rising using the Q and E keys on Linux because the game doesn't support bindings that rotate the camera. It uses `uinput` to emulate a right click and drag.

## Usage

Your user must be part of the input group.

```
sudo usermod -aG input $USER
```

Log out/in, then run the script.

```
./vrising-cam.py
```

### Options

| Flag                   | Meaning                                                                                                             |
| ---------------------- | ------------------------------------------------------------------------------------------------------------------- |
| `--speed N`            | rotation speed in relative X units per second (default `2000`)                                                      |
| `--tick-ms N`          | milliseconds between motion ticks (default `1.0`; lower = smoother, higher = lighter)                               |
| `--ease SECONDS`       | ramp speed up over `SECONDS` on press and decay on release (`0` = off; try `0.15`)                                  |
| `--invert`             | swap the rotation direction of Q and E                                                                              |
| `-v`, `--verbose`      | log key presses/releases, RMB injection, measured motion rate                                                       |
| `--test-rmb [SECONDS]` | self-test: hold the injected RMB for `SECONDS` (default 3) and read events back from the kernel; no keyboard needed |
| `--check`              | show detected keyboards, uinput and grab status, then exit                                                          |
