# Kamera

Camera package for Ebitengine.

```Go

import "github.com/setanarut/kamera/v2"

```

## Features

- Camera shake effect with [fastnoise](https://github.com/setanarut/fastnoise) library noise types.

- Smooth camera movement with three interpolation modes:

  - `None`: Direct camera movement without smoothing

  - `Lerp`: Linear interpolation for smooth transitions

  - `SmoothDamp`: Spring-like motion with acceleration and deceleration and maximum speed.

- Rotate/Zoom

## Usage

A pseudo code:

```Go

func (g *Game) Update() error {

  g.MainCamera.LookAt(player.X, player.Y)

  // Apply all world-space `playerDrawImageOptions.GeoM{}` transform here

 }

func (g *Game) Draw(screen *ebiten.Image) {

  g.MainCamera.Draw(playerImage, playerDrawImageOptions, screen)

 }

```
