Drawing a image from a for loop?

Hey, I'm trying to use love.graphics.draw entirely with table data.
Code: Select all
for k,v in pairs(buttons) do
g.draw(v.pic, v.x, v.y)
end
And here is the table.
Code: Select all
buttons = {
["Start"] = {x = 250, y = 350, width = 100, height = 50, pic = img_btnStart, picClick = img_btnStart_click, click = false, state = 0}
}
It seems so simple but I can't figure it out haha.

Could you post all your code? would make helping you easier.
First, In the loop you call g.draw, Isn't it supposed to be v.draw? 2nd, Is the draw method even defined?
And third, what exactly is the problem, Are you getting an error?

No error, the g.draw is love.graphics.draw, my apologies for not specifying that. And this is the only code other than just love.draw ' ing it that pretains to this code.

Code: Select all
g = love.graphics
img_btnStart = gfx.newImage("test.png")
buttons = {
["Start"] = {x = 250, y = 350, width = 100, height = 50, pic = img_btnStart, picClick = img_btnStart_click, click = false, state = 0}
}
function love.draw()
for k,v in pairs(buttons) do
g.draw(v.pic, v.x, v.y)
end
end
It seems to work for me; just plop a test.png in the folder you're working with (or check out muh .love!
)
I have a suspicion that you forgot to include the love.draw() function, or put the g.draw call in the wrong place. Drawing stuff is only possible in love.draw!

I'm using love 0.8.0. Here is the .love. menu.lua is where the errors are.

You're calling "LOAD_BUTTONS()" where the button picture is defined before you load the image in love.load, So buttons["start"].pic is nil.

Why not upgrade to 0.9.0?
