I want to repeat my ground when my player hit the second part of the ground.

Hi,

I am working on my first game which is an endless car racing and since I am new I face difficulty in writing the perfect codes.

As per the attachment, I need help to repeat my ground which consist of 2 platforms and every time when my player crosses the first platform I want the same to start over at the end of second platform.
Actually I have pretty much done that and the platform repeating itself but I actually want my player to repeat that platform for me rather than platform repeating itself.

Please help me in writing the correct code that when my player hit the second platform the first platform should repeat again after second platform.

 

Put platform into prefab, and instantiate/spawn another one before player reaches the end of it.

 

Thanks for the idea @neginfinity , it really worked.
