Hi,I'am planning to make a WWE wrestling game,can anyone tell me is it possible to make a wrestling game in 3D Gamestudio.If possible,how?

You should post on beginner section not here !

Yes it is possible to make any fighting game.
You'll have to handle distance between oponents, their stance , and some vertex position of hands, foots , body parts etc ...

Only one word : HARD WORK

actually this are two words

Anyways, I just can agree with ratchet.

And this doesn't count only for a WWE wrestling game.
It can be a huge amount of work to create a game (any genre) and a lot of experience and knowledge is needed to get somthing good in the end.

With 3DGS you can make everything but I can't tell you how to create a specific game simply because this is something really complex and there's never just one right way to make something in 3DGS.

...and since it looks like you're pretty new here I suggest you to start with the workshops
