As you probably know in Bubble Ball, in game, there is a start button and when it is pressed everything starts such as like the ball drops and the wood ramps drop because they are all affected by gravity. I would like to know how to make all the physics engines turn on with a button press?!
Please Help-

–on press
physics.start()
?
or you can also do it like this
–on press
physics.setGravity(0, 9.8)
–If reset or whatever…
physics.setGravity(0, 0) [import]uid: 6981 topic_id: 8036 reply_id: 28616[/import]
Ok yes that is what i am looking for but my buttons are not working, I have the ui.lua and i dont really know what to do!!

Post your code. [import]uid: 11809 topic_id: 8036 reply_id: 28620[/import]
Here is all my code, if you could, could you pleas like add a button to the code!!
Thanks-

You could really improve that code man.
Why have two references for the same thing ? (ie the ramp)
How about spawning them or having a table of ramps ?

Well I am just experimenting with different bits of code… So if someone could please just help me out with the buttons and just like add a button to the code i would be very happy!!
