Probleme generating a world

Is there any better way to display 90 object each frame than writing 90 lines of sprite displaying? Because I need to update it each frame so that I can make my man move… My try:

if BlockCount ~= 90 then
        sprite("Planet Cute:Grass Block", BlockPosition.x, BlockPosition.y)
        BlockPosition.x = BlockPosition.x + 101
        if BlockPosition.x > 1024 then
            BlockPosition.x = 57
            BlockPosition.y = BlockPosition.y - 80
        end
        BlockCount = BlockCount + 1 
    end

Sorry if the code didnt display right!

Try using tables to make a 2D “info” map, (@Ignatz covers that better than I can explain in his ebook)

@g1t2r3 - put ~~~ on a line before after your code to make it look nice

try this, it creates a picture at the beginning with all your grass blocks, then you only need to draw that one picture each time after that

function setup()
    --put your other setup code first, then this..
    local img=readImage("Planet Cute:Grass Block")
    local w,h = img.width, img.height
    local x = 10 --number of times to copy image left to right
    local y = 9 --number of times to copy image top to bottom
    grass=image(x*w,y*h)
    setContext(img) --draw to image instead of screen
    for i=0,x-1 do
        for j=0,y-1 do
            sprite(img,i*w+1,j*h+1)
        end
    end 
    setContext()
end

--then in draw
sprite(grass, x, y ) --choose x,y to position it correctly

Im not sure its working… When I run it, it gets me a black screen!

All the other mechanics for my games are ready! Im missing that one piece of code!

Try this, it also trims the image to get rid of the edges

function setup()
    --put your other setup code first, then this..
    local img=readImage("Planet Cute:Grass Block")
    img=img:copy(4,45,95,73)
    local w,h = img.width, img.height
    local x = 10 --number of times to copy image left to right
    local y = 9 --number of times to copy image top to bottom
    grass=image(x*w,y*h)
    setContext(grass) --draw to image instead of screen
    for i=0,x-1 do
        for j=0,y-1 do
            sprite(img,i*w+1,j*h+1)
        end
    end 
    setContext()
end

--then in draw
function draw()
    background(100)
    sprite(grass, 400, 400 ) --choose x,y to position it correctly
end

Thx!! Working perfectly!
