Lua and Love2D, table in table error

Question

Why isn't this working? I'm trying to put all my object tables in a single table and use a forloop to iterate through each of them and draw. It shows an error message saying: "}" expected near "=" at line 5

function love.load()
solidstatic = {
ground = {x = 0,y = 160,width = 1000,height = 1000},
box = {x = 80,y = 100,width = 15,height = 15}
}

end


function love.draw()
for i,obj in ipairs(solidstatic) do
love.graphics.rectangle("fill",obj[x],obj[y],obj[width],obj[height])
end
end

(edit) solved the error problem, I was running the wrong .lua file. But still, it doesn't draw anything on the screen

The solidstatic table has no array keys so ipairs doesn't iterate over anything. — Etan Reisner

Two things. Firstly, you must use pairs instead of ipairs to list keys that are not numbers.

for i, v in pairs(table) do
    ...
end

You must also index the variables as a string.

t = {
    x = 1
}

t['x'] = 1
-- or
t.x = 1

This is because doing it without quotes would be indexing with the global variable x, which doesn't exist.

You need to use pairs instead of ipairs to iterate over elements in solidstatic as there are no array keys in that table.
