Pausing a simple animation

 --- EXAMPLE ---
When I hit "play" this code runs: 


on mouseUp
  send animateTokens to card "myCanvas" in 10 milliseconds
end mouseUp 


This invokes the handler: 


on animateTokens
 global b_play
 put TRUE into b_play
 repeat for each line L in field "frames"
   set the lockMoves to true
   repeat with i = 1 to the number of images in group "tokens_group"
     move image i of group "tokens_group" to coords without waiting
   end repeat
   set the lockMoves to false
   if not b_play then break
 end repeat
end animateTokens

=============
Mr Biancolo, 

Perhaps this work-around for a mouseDown on a HALT button can work for you. 
The HALT button doesn't need any script, so you can eliminate the global 
b_play. 

on animateTokens

 repeat for each line L in field "frames"
   set the lockMoves to true
   repeat with i = 1 to the number of images in group "tokens_group"
     move image i of group "tokens_group" to coords without waiting
   end repeat
   set the lockMoves to false
   if within(button "HALT", the mouseLoc) and (the mouse is down) then
      break
   end if
 end repeat
end animateTokens
