Loading Sprites into a Project

kendog400

I would like to load a sprite sheet from the kenney / board games into a project. A deck of cards. I'm still trying to figure out how..
Is there any tutorial or help I could find ? This photo upload is from Untied Games.....!

This would help very much, and would help me get the ball rolling.......In Codea / lua they would have Hearts, Spades, Diamonds and Clubs in a section with other icons, and you would make an Array for your deck of cards, here in Fuze you would have to use a sprite sheet.....Which is fine if I only knew how..

@kendog400 Hi have a look at this example of how to chop an image up into separate sprites https://fuzearena.com/forum/topic/437/fun-with-sprites/7

If the image is tiled like this one you can use gettilesize to find the size of a tile

ts = gettilesize(image, n) // ts is tilesize n is the tile number

A sprite can also have associated variables so you could have:

sprite.suit = "Hearts"
sprite.value=9

I find that using the sprite commands works well when there are lots of animation frames, but given that each card is only a single frame - you might find it simpler to use the drawSheet function. https://fuzearena.com/help/view/drawSheet

You might want your program to start something like:

// load the image file
sheet = loadImage("Untied Games/Playing cards")

// create a structure type for a card, used for the deck, hands, revealed cards, etc
struct card_type
    str suit
    int val
    vec pos
    int img
endstruct

// now when we declare an array using the card_type, each element has all those properties above.
card_type deck[52]

// We could manually setup the data or use a loop that went over each suit and set the properties for each card:

i = 9 // this is the number of the first card image tile in the sprite sheet
c = 0 // deck array index
for suit = 0 to 4 loop // loop over each suit
    for value = 1 to 14 loop // loop over each card in the suit
            if suit == 0 then deck[c].suit = "Clubs" endif
            if suit == 1 then deck[c].suit = "Diamonds" endif
            if suit == 2 then deck[c].suit = "Hearts" endif
            if suit == 3 then deck[c].suit = "Spades" endif
            deck[c].val = value // set the value of the card to the value counter 
            if deck[c].val > 10 then deck[c].val = 10 endif // cap the value off at 10, if this was blackjack for instance
            deck[c].img = i // set the image tile number from the spritesheet
            i += 1 // increase the img counter
            c += 1 // increase the card counter
    repeat
repeat

We can then use the .img property of any card in the deck array to index the drawSheet function to draw cards

// draw a random card in the middle of the screen at a scale of 4:
scale = 4
width = tileSize( sheet, 0 ).x * scale
height = tileSize( sheet, 0 ).y * scale
c = random(52)
drawSheet( sheet, deck[c].img, { gwidth()/2, gheight()/2, width, height}  )
update()
sleep(100) // I have to go to bed

I'm sure there are simpler ways to get started but this is the sort of setup I would use. I think it gives you everything you need in a handy place. Let me know if you want any of it elaborated on I tried to be thorough in the comments.

Very helpful, I will be at the drawing board soaking this up..If I have to much trouble, I'LL be back to ask for a demo of the random card. But I'LL try to figure this out 1st...
