hello everyone 
i am almost done the bigger part of my gameplay, but i have some small problems that I left to other time because i did not know how to solve this, now i need some help to finish this small problems of my gameplay:
1Âș first problemâŠresolved thanks ng and info642
2Âș problem⊠on the if statement, i create a block, that have limit to 3, and when i create a object, it is counting #block, create and he add + 1, now i cant make when i remove the object i need to #block -1, remove a object from the counting
see the bigger comment on code
on this code have 2 more things to correct:
1Âș run the code you will see it:
- if you create a block and after click on the ball and after create another ball, will see it, the object that you create before the ball, you can drag it, and the block that you create after you can drag, and i need to stop all draggable objects
the second error:
if i click on the ball i should cant create more block, and i can 
that is all problems that remaining on my test code, i really need to finish it without errors because i need to go to final code, and cant resolve this problems because i dont know how i can make it

⊠and have one more problem, that i will post on another day
Thanks very much people
