python - Combine effects to menu in pygame -
hey guys developing game pygame. idea of game when user click on start button on menu(which appear on first before starting game) must see 2 balls bouncing on pygame window.
for have 2 python files.
bounceball.py
this python file makes 2 ball bounce on pygame window made me.the code of bounceball.py here.(sorry pasting on pastebin since long code)
menu.py
this python file creates menu have found internet , works fine.the code of menu.py here
but problem when user clicks on start button menu didnt .the thing want when user clicks on start button menu must see ball boucing have coded in bounceball.py on pygame window.how can link bounceball.py menu.
i have tried acheive many methods didnt helped me ..
hope guys can me in acheieving ..any appreciated ..thanks in advance
it done better @ least works.
menu.py
