I am trying to consolidate my code with loops.
function renew()
for i=1, 5, 1 do
Rect[i]:setFillColor(100,170,180)
end
end The problem is when i try the set the color of the I in the third line of the code.
Im not sure how to do this.
Thanks

You aren’t giving us quite enough info here about the error but my guess is perhaps Rect isn’t a table? Here is one example of how this would work;
[lua]local Rect = {}
for i = 1, 5 do
Rect[i] = display.newRect( i*20, i*20, 20, 20 )
end
local function renew()
for i = 1, 5 do
Rect[i]:setFillColor(255, 0, 0)
end
end
renew()[/lua]
(Keep in mind you could use #Rect rather than 5 on line 8)
Or if you aren’t creating them in a loop you could do;
[lua]local Rect = {}
Rect[1] = display.newRect( 20, 20, 20, 20 )
Rect[2] = display.newRect( 90, 200, 20, 25 )
Rect[3] = display.newRect( 220, 300, 30, 20 )
local function renew()
for i = 1, #Rect do
Rect[i]:setFillColor(255, 0, 0)
end
end
renew()[/lua]
(In that second example I use #Rect)
I hope this helps

I was originally using independent Rects, but ill try to set it up using a *table* like your second example.
Just out of curiosity what would you have to do if it wasn’t a table?

Well you need to use a table if you’re using a for loop like above because otherwise there would be nothing to iterate through.
If it wasn’t a table you’d have to set the colors one at a time.
Eg;
rect1:setFillColor(255,0,0)
rect2:setFillColor(255,0,0)
rect3:setFillColor(255,0,0)
etc. [import]uid: 52491 topic_id: 25685 reply_id: 103868[/import]
