# 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()
|
|
}
|
|
}
|
|
```
