This Defold Native Extension allows receiving a system uptime.  
**This timer resets when user restarts their device!**

Possible use cases:

- If you want to use a timer for restore lives (or something else) in your game without server but want to have better protection against cheaters who just change system time.
- Seed for math.randomseed() (thanks @dragosha for that use case idea)

## Platforms

- **iOS**
- **MacOS**
- **Android**
- **Windows**

## Setup

You can use the UpTime extension in your own project by adding this project as a [Defold library dependency](https://www.defold.com/manuals/libraries/). Open your game.project file and in the dependencies field under project add:

> [https://github.com/AGulev/uptime/archive/master.zip](https://github.com/AGulev/uptime/archive/master.zip)

Or point to the ZIP file of a [specific release](https://github.com/AGulev/uptime/releases).

## API

#### `uptime.get()`

Returns system uptime in seconds.

```lua
local function update_uptime(self)
  if uptime then
    local uptime = uptime.get()
    print(uptime) -- 809031
  end
end

```
