# NTween

A simple library implementing tweens for [Odin language](https://odin-lang.org).

There's already [flux-tween](https://github.com/odin-lang/Odin/blob/aa36ae01cf4e4d665fb190b9f00237dfad9d21ee/core/math/ease/ease.odin#L359) in the standard library,
but it was somewhat difficult to understand at first so I've made one myself.

## Features 

- basic float values tweening
- array values tweening (vec2 and vec3 for example)
- supports easings from `core:math/ease`
- callbacks after completion

## Installing

You can clone this repo inside of your project and then just import the library using `import ntween`

## How it works?

Check out `examples` folder. The callbacks one is not working right now but it's gonna be fixed.

### Very basic example

```odin
package main

import nt "ntween"
import rl "vendor:raylib"
import "core:math/ease"

main :: proc() {
    rl.InitWindow(800, 600, "hellope, tweens!")
    
    tw := nt.init(f32)
    pos : f32 = 100.0
    
    nt.animate(&tw, &pos, 700, 2, ease.Ease.Bounce_Out)


    for !rl.WindowShouldClose() {
      delta := rl.GetFrameTime()
      nt.process(&tw, delta)

      rl.BeginDrawing()
      rl.ClearBackground(rl.BLACK)
      rl.DrawRectangleV({pos, 100}, {30, 30}, rl.WHITE)
      rl.EndDrawing()
    }
}
```
