I started a project of a card game.
When you hit a button you flip a random card.
Ive created some awsome playingcard pack, these are 53 png files.
I like to import them.
But the only problem is, i got a wierd code that draws the cards by code.
Can somebody help me to use my own png,s instead of the code cards?
Here is my card class
--# Card
Card = class()
--[[this class builds and draws the card images from scratch and provides some utilities
--]]
--class initialises by creating card design
--Parameters:
--height of card in pixels
--the image to be used on the back
--background color on the face of the card
--(optional) background color on the back of the card
-- (optional) color along the border ofthe card
--returns nothing
function Card:init(height,backImg,faceColor,backColor,borderColor)
self.height = height
self.backImg=backImg
self.f=height/200 --scale font size to card size
self.faceColor=faceColor or color(255)
local x=100 --default border color
self.borderColor=borderColor or color(x, x, x, 255)
x=x*1.5 --corners are drawn with circles which appear darker than lines, so lighten colour for them
self.cornerColor=borderColor or color(x,x,x, 150)
self.backColor=backColor or color(240, 239, 237, 255)
self:createCard()
self:createSuits()
self.value={"A","2","3","4","5","6","7","8","9","10","J","Q","K"}
self.suit={"S","H","D","C"}
end
--this and the next function build just the front and back of the card itself
--the main problem is rounded corners
--this is done by drawing circles at the corners and then overlapping rectangles forthe final effect
function Card:createCard()
self.cardFace=self:createOutline(true)
self.cardBack=self:createOutline(false)
end
function Card:createOutline(face)
--use standard 25/35 ratio
self.width=math.floor(self.height*30/45+.5)
local img=image(self.width,self.height)
--create rounded corner on top right
local corner=0,05 --distance from end of card as percent of height
local c=math.floor(corner*self.height+0.5)
setContext(img)
pushStyle()
strokeWidth(1)
stroke(self.cornerColor)
--set background colour
if face then fill(self.faceColor) else fill(self.backColor) end
--draw small circles at corners
ellipse(self.width-c+1,self.height-c+1,c*2)
ellipse(self.width-c+1,c-1,c*2)
ellipse(c-1,self.height-c+1,c*2)
ellipse(c-1,c-1,c*2)
if face then stroke(self.faceColor) else stroke(self.backColor) end
--now rectangles to fill in thre centre of the card
rect(0,c,self.width,self.height-c*2)
rect(c,0,self.width-c*2,self.height)
--now a border round the card
stroke(self.borderColor)
line(0,c,0,self.height-c)
line(c,0,self.width-c,0)
line(self.width,c,self.width,self.height-c)
line(c,self.height,self.width-c,self.height)
--do picture on back
if face~=true then
sprite("Documents:cb",img.width/2,img.height/2,img.width*.9)

popStyle()

--the suit images come from emoji
function Card:createSuits()
