Hi,
I need to make a bubble shooter game.
Can anyone tell me from where do I start?
How to build the mechanics of the game?
I have tried a lot but its not getting done.
And I have tried to explore it on google but not able to find any solution. 
what are you trying so far for a design?
I have made one bubble and make that going upward.
I just want to know how can I arrange the bubbles randomly and hit them with this bubble.
Then the main problem comes that I need to fall that bubble down if the 3 gets matched.
I really need from this community because I am not finding it from any where else.
make several Sprite objects in a for loop and randomly create values and assign with setPosition()
Well, we don’t teach game design concepts. We are a game engine that you use to facilitate your designs.
I wrote a game that basically does the concepts you need. It took me 3 months of weekends to complete it.
What is name of the game?
Can I find that on github?
If you have then please provide me the code, so that it might get a bit easier for me to code my own game by taking help from that.
it is not public on GitHub, sorry.
You can’t really copy someones code and make a game efficiently. The most efficient and rewarding way is to learn the concepts, usually by reading and the school of hard knocks. 
I am trying my level best.
And If stuck in between the I will call you for the help.
And ya thanks a lot for the suggestions.
We are here to help!
