unity3d - What is the code to add physics to the rigidbody in unity 5.0.0p2? -

the following code seems wrong in unity 5.0.0p2:

rigidbody2d.velocity.x = input.getaxis("horizontal") * 10; 

so tried following code:

getcomponent<rigidbody2d>().velocity.x = input.getaxis("horizontal") * 10; 

but still not working. several error messages appear follows.

• bce0043: unexpected token: ).
• bce0044: expecting ), found '.'.
• uce0001: ';' expected. insert semicolon @ end.

what wrong code?

your first line no longer work because rigidbody2d no longer property of monobehaviour. has been removed, have use getcomponent<rigidbody2d>() instead.

that doesn't fix problem however. cannot update velocity do, setting x value. have assign full vector. copy current velocity vector3 of own, update x , replace whole velocity vector.
