Drawn png's

edited July 2013 in Questions Posts: 18

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) end popStyle() setContext() return img end --the suit images come from emoji function Card:createSuits() font("AppleColorEmoji") self.suits={unicode2UTF8(9824),unicode2UTF8(9829),unicode2UTF8(9830),unicode2UTF8(9827)} end --draws a card at x,y with value of card (1-52), face=true if face up, a=angle in degrees (default 0) function Card:draw(x,y,card,face,a) pushMatrix() translate(x+self.width/2,y-self.height/2) if a==nil then a=0 end rotate(a) if face then if card>0 then self:drawDetails(card) else sprite(self.cardFace,0,0) end else sprite(self.cardBack,0,0) end popMatrix() end --draws the numbers and symbols on the front of the card --one parameter = card value function Card:drawDetails(card)

    Well, thank you, Draakk, I had no idea my code was weird :))

    @Draakk - you need to read your pngs into a table with readImage, so they are available when needed.

    If you don't know how to do that, please read up on Lua's tables, and see the documentation on readImage, or the many tutorials in the wiki. The people in the forum are happy to help, but they can't be expected to write all the code for you. When I started Codea, I read all the tutorials I could find, before I tried any projects of my own.
