REQUESTING HELP

[Aurora_TheGreat]

Hi! I'm kinda new and I really need help to find out what's wrong with my coded, can someone help me please?

function love.load()
totalStars = 1000
stars = {}

for i = 0, totalStars, 1 do

stars [1] = {
r = love.math.random(0,255) / 255,
g = love.math.random(0,255) / 255,
b = love.math.random(0,255) / 255,
a = love.math.random(0,255) / 255,
x = love.math.random(0, love.graphics.getWidth()),
y = love.math.random(0, love.graphics.getHeight()),
radio = love.math.random(1,5)
}
end
end

function love.draw()
for i = 0, totalStars, 1 do
love.graphics.setColor(
stars.r,
stars.g,
stars.b,
stars.a
)
love.graphics.circle(
"fill",
stars.x,
stars.y,
stars.radio)
end
end


function love.update(dt)

stars[100].x = stars[100].x + 1
stars[100].y = stars[100].y + 1

if stars[101].x > love.graphics.getWidth() then
stars[101].x = 0
end

if stars[101].y > love.graphics.getHeight() then
stars[101].y = 0
end

end



And this is what appears to me when I run it:
Error

main.lua:39: attempt to index a nil value

Traceback

Welcome to the forums.

The issue is here:

Code: Select all

for i = 0, totalStars, 1 do
  stars [1] = { -- the "1" here is the problem
    r = love.math.random(0,255) / 255,
    g = love.math.random(0,255) / 255,
    b = love.math.random(0,255) / 255,
    a = love.math.random(0,255) / 255,
    x = love.math.random(0, love.graphics.getWidth()),
    y = love.math.random(0, love.graphics.getHeight()),
    radio = love.math.random(1,5)
  }
end

If you look at that for loop carefully, you only ever assign tables to the slot 1. As such, when you try to access slot 100 in your love.update, that slot is not defined, leading to a nil index error.

You will need to change the code above to this:

Code: Select all

for i = 0, totalStars, 1 do
  stars [i] = { -- simply swap the "1" with "i"
  -- ...rest of the code
