# Kamera

Camera package for Ebitengine.

```Go

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

```

https://github.com/user-attachments/assets/58787fbe-5788-43d4-9560-482dcc965efb

## 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 {

  MainCamera.LookAt(playerCenter.X, playerCenter.Y)

  return nil

 }

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

  playerDrawImageOptions.GeoM.Reset() // GeoM must be reset

  playerDrawImageOptions.GeoM.Translate(target.X, target.Y) // Move player

  MainCamera.Draw(playerImage, playerDrawImageOptions, screen)

 }

```

## Examples

1. Clone this repository

2. In the terminal, change directory to the examples folder `cd examples`

3. Run a demo with `go run ./folder_name` (`go run ./platformer`, `go run ./director`).
