I am trying to create a bunch of buttons in a FOR loop. What is the best practice to go about doing this? I need to be able to change the button text outside the loop in another function.

Code:

        

for p=1,4,1 do

        myButton[p] = Chain( wm:CreateControl("button"..p, ss, CT_BUTTON) )

                        :SetDimensions(50,50)

                        :SetText("button"..p)

                        :SetAnchor(TOPLEFT, ss, TOPLEFT, 0,(p*50)-50)

                        :SetFont("ZoFontAlert")

                .__END

end

myButton[p]:SetText("newname")

What you're doing is fine. Are you having issues?

Well going further I have several objects I create in the loop along with the button. I wanted to keep them together in a structure of some sort. For example:

Code:

local node = {}



for p=1,4,1 do

        node[p].button = Chain( wm:CreateControl("button"..p, ss, CT_BUTTON) )

                        :SetDimensions(50,50)

                        :SetText("button"..p)

                        :SetAnchor(TOPLEFT, ss, TOPLEFT, 0,(p*50)-50)

                        :SetFont("ZoFontAlert")

                .__END

end



function update()

  node[1].button:SetText("newname")

end

Which would not work so I tried something like this but then I cant reference the button text anymore.

Code:

local node = {}



for p=1,4,1 do

        thisNode = node[p]

        thisNode.button = Chain( wm:CreateControl("button"..p, ss, CT_BUTTON) )

                        :SetDimensions(50,50)

                        :SetText("button"..p)

                        :SetAnchor(TOPLEFT, ss, TOPLEFT, 0,(p*50)-50)

                        :SetFont("ZoFontAlert")

                .__END

end



function update()

  thisNode = node[1]

  thisNode.button:SetText("newname")

end

Let me guess.. you get a nil error?

If you want to use tables, you need to declare them properly, here's two approaches:

Lua Code:

local node = {} -- define node tables
 
for p=1,4,1 do
  node[p] = {} -- define inner table
  node[p].button = YourButtonFunction(..)
end
 
for i=5,8,1 do
  node[i] = {
    button = YourButtonFunction(..)
  }
end
 
for j=1,8,1 do
  d(node[j])
end

Add local in front of each thisnode assignment.

Thanks that really pointed me in the right direction for what I needed
