    viewing outside of the player

    Unknown Member
    in General questions
    is there a way to view (gideros player) outside of the frame where we define our logical width and height? like the box2d collision example, where the box is created outside of the frame with the value -ve i would like the option to see it, as i want to make a platformer type game where the "stage" is bigger then the screen size, i hope i'am making myself clear
    Hello everyone, my name is Tulip, nice to meet you.

      You can use my camera library :smile: (see signature)


      local random = math.random
local function frandom(min, max) 
	return min + (max-min) * random() 
end
 
local Layer = Sprite.new()
local RECT_SIZE = 10000
 
local cam = GCam.new(Layer)
cam:setAutoSize(true)
cam:setBounds(-RECT_SIZE, -RECT_SIZE, RECT_SIZE, RECT_SIZE)
cam:goto(cam.w / 2, cam.h / 2)
--cam:setDebug(true)
stage:addChild(cam)
Layer:addChild(Pixel.new(0,0.5, cam.w,cam.h))
 
for i = 1, 20000 do 
	local sq = Pixel.new(random(0xffffff), frandom(0.5, 1), 
		random(10,80), random(10,80)
	)
	sq:setAnchorPoint(.5,.5)
	sq:setRotation(random() * 360)
	sq:setPosition(
		random(-RECT_SIZE, RECT_SIZE),
		random(-RECT_SIZE, RECT_SIZE)
	)
	Layer:addChild(sq)
end
