Hi,I have tried to add 2 buttons, first button to start the bouncing balls and the random number generation 2nd button to stop the bouncing balls and the random number generation.But due to the arrangement of the variables/parameters, i cant seem to get the button to work. (i.e the parameter t appears after the button definition.)Could someone help me to quickly complete this portion please? My demo to the CEO if i want to show Curl will be 1.5 days away.Thanks,PTKamal Bhatt [EMAIL PROTECTED] wrote: There are various ways to do what you want.The example
belowuses an HBox. I would suggest reading more about different containers and see what suits you best for your application.

Can you tell me how i can make the 2 balls separated by a horizontal distance of 2in and the random number
