# Spotlight
## Gradle
```groovy
dependencies {
implementation 'com.github.takusemba:spotlight:x.x.x'
}
```
## Usage
```kt
val spotlight = Spotlight.Builder(this)
.setTargets(firstTarget, secondTarget, thirdTarget ...)
.setBackgroundColor(R.color.spotlightBackground)
.setDuration(1000L)
.setAnimation(DecelerateInterpolator(2f))
.setContainer(viewGroup)
.setOnSpotlightListener(object : OnSpotlightListener {
override fun onStarted() {
Toast.makeText(this@MainActivity, "spotlight is started", Toast.LENGTH_SHORT).show()
}
override fun onEnded() {
Toast.makeText(this@MainActivity, "spotlight is ended", Toast.LENGTH_SHORT).show()
}
})
.build()
```
If you want to show Spotlight immediately, you have to wait until views are laid out.
```kt
// with core-ktx method.
view.doOnPreDraw { Spotlight.Builder(this)...start() }
```
## Target
Create a Target to add Spotlight.
Target is a spot to be casted by Spotlight. You can add multiple targets to Spotlight.
```kt
val target = Target.Builder()
.setAnchor(100f, 100f)
.setShape(Circle(100f))
.setEffect(RippleEffect(100f, 200f, argb(30, 124, 255, 90)))
.setOverlay(layout)
.setOnTargetListener(object : OnTargetListener {
override fun onStarted() {
makeText(this@MainActivity, "first target is started", LENGTH_SHORT).show()
}
override fun onEnded() {
makeText(this@MainActivity, "first target is ended", LENGTH_SHORT).show()
}
})
.build()
```
## Start/Finish Spotlight
```kt
val spotlight = Spotlight.Builder(this)...start()
spotlight.finish()
```
## Next/Previous/Show Target
```kt
val spotlight = Spotlight.Builder(this)...start()
spotlight.next()
spotlight.previous()
spotlight.show(2)
```
## Custom Shape
`Shape` defines how your target will look like.
[Circle](https://github.com/TakuSemba/Spotlight/blob/master/spotlight/src/main/java/com/takusemba/spotlight/shape/Circle.kt) and [RoundedRectangle](https://github.com/TakuSemba/Spotlight/blob/master/spotlight/src/main/java/com/takusemba/spotlight/shape/RoundedRectangle.kt) shapes are already implemented, but if you want your custom shape, it's arhivable by implementing `Shape` interface.
```kt
class CustomShape(
override val duration: Long,
override val interpolator: TimeInterpolator
) : Shape {
override fun draw(canvas: Canvas, point: PointF, value: Float, paint: Paint) {
// draw your shape here.
}
}
```
## Custom Effect
`Effect` allows you to decorates your target.
[RippleEffect](https://github.com/TakuSemba/Spotlight/blob/master/spotlight/src/main/java/com/takusemba/spotlight/effet/RippleEffect.kt) and [FlickerEffect](https://github.com/TakuSemba/Spotlight/blob/master/spotlight/src/main/java/com/takusemba/spotlight/effet/FlickerEffect.kt) shapes are already implemented, but if you want your custom effect, it's arhivable by implementing `Effect` interface.
```kt
class CustomEffect(
override val duration: Long,
override val interpolator: TimeInterpolator,
override val repeatMode: Int
) : Effect {
override fun draw(canvas: Canvas, point: PointF, value: Float, paint: Paint) {
// draw your effect here.
}
}
```
