Challenge 4 - Colour buttons

[litdev]

Hi,

Like others, I'm not really sure what the issue is and don't think describing how it works will add anything.

In my example I set the button to the element of an array.

Code:

button[i] = Controls.AddButton("",buttonX[i],buttonY[i])

In your example you use separate variables for each button:

Code:

ButtonRed = Controls.AddButton("",10,10)

In these cases, they "work independently of the internal button name ".

In the example by JR, he does use the internal variable name - it works, but I would always prefer to store in a local user variable.  This looks like maybe a lucky oversight by JR.

Code:

Button1=Controls.AddButton("My Button1",0,0)
...
If Controls.LastClickedButton = "Button1" then

The only time I might consider using the internal name is to access a large number of shapes without referring to user variables, for example removing Turtle lines (that are shapes). 

Equally, and proably better would be:

Code:

Button1=Controls.AddButton("My Button1",0,0)
...
If Controls.LastClickedButton = Button1 then

Actually, the following would also work, but clearly is harder to follow:

Code:

Controls.AddButton("My Button1",0,0)
...
If Controls.LastClickedButton = "Button1" then

This is partly why I used arrays to store the buttons in my example.

EDIT

Note the [i] array index in "button[i] = Controls.AddButton("",buttonX[i],buttonY[i]) ", which you missed in your post that confused me a bit.
