My camera class with pinch to zoom

anskurt

I made a Camera class for my game since i couldn't find one i liked. I'm really pleased with how it turned out so i decided to share it here. The camera can follow an object, be dragged around with your finger and zoom with pinching.

How to use:
If you want the camera to follow something, like the player:

local world = Sprite.new() local camera = Camera.new(world) camera:setFollowMode() local player = Sprite.new()   function onEnterFrame() camera:setTarget(player:getPosition()) camera:update() end   world:addEventListener(Event.ENTER_FRAME, onEnterFrame)   world:addChild(player) stage:addChild(world)

If you just want to drag around the camera with your finger:

local world = Sprite.new() local camera = Camera.new(world) --set the starting place of the camera if you want camera:setTarget(100, 100) --addsome random game object local Ball = Bitmap.new(Texture.new("ball.png"))   function onEnterFrame() camera:update() end   world:addEventListener(Event.ENTER_FRAME, onEnterFrame) world:addchild(Ball) stage:addChild(world)

So basicly make a sprite that is your world or your scene, create the camera with the sprite in the constructor.
Then add every object as child to that sprite.
And run Camera:update() on every frame.

Right now the camera has no limit on how far it can go in any direction, if you add that or any other improvement please post it here
