Show the Last Actions from a Timeline Row

Create buttons 1, 2 & 3 from the image below:

• Button 1 - A label button with the button ID 'us'.
  This button is connected to button 3 by an activation link.
• Button 2 - A label button with the button ID 'them'.
  This button is also connected to button 3 by an activation link.
• Button 3 - A code button with a lead time of 2 seconds and a lag time of 2 seconds. This button has the button ID 'variable'.
  This button creates an instance on the timeline.

Create buttons 4, 5 & 6 from the image above to form the Color Palette:

• Button 4 - An inactive button with the button ID 'color1'.
  This button should be the same color as button 1.
• Button 5 - An inactive button with the button ID 'color2'.
  This button should be the same color as button 2.
• Button 6 - An inactive button with the button ID 'color3'.
  This Button should be a neutral color.

Create button 7 from the image above to display who had the last chance in the 'variable' row:

• Button 7 - An inactive button with the button ID "last1".

Give button 7 the following script:

button color #'color3'
This script sets the button color as the neutral 'color3' from the Color Palette.

$lastinstance = instances where row = #'variable' limit -1,-1
The limit here is set to show the last instance added to the 'variable' row.

$ourwin = count "Us" and $lastinstance
$theirwin = count "Them" and $lastinstance
These variables will count whether the last instance added to the row contains the label 'Us' or 'Them'.

if($ourwin = 0, show "-")
if($theirwin = 0, show "-")
If there are no labels in the timeline 'variable' row instances then this button will display the '-' symbol.

if($ourwin = 1, show "US")
if($theirwin = 1, show "Them")

if ($ourwin = 1, button color #'color1')
if ($theirwin = 1, button color #'color2')

The last two lines of script set the button color, dependent on which label is in the instance.

Create buttons 8 & 9 from the image above. These buttons contain the same script as button 7, apart from line 3 of the script (see below script and image):

• Button 8 - An inactive button with the button ID 'last2'.
  This button has the following script on line 3:
  $lastinstance = instances where row = #'variable' limit -2,-2

The limit here is set to show the second last instance added to the 'variable' row.

• Button 9 - An inactive button with the button ID 'last3'.
  This Button has the following script on line 3:
  $lastinstance = instances where row = #'variable' limit -3,-3

The limit here is set to show the third last instance added to the 'variable' row.

Create buttons 10 & 11 from the image above. These buttons contain the same script as button 7, apart from line 3 of the script (see below script and image):

• Button 10 - An inactive button with the button ID 'last4'.
  This Button has the following script on line 3:
  $lastinstance = instances where row = #'variable' limit -4,-4
