I presume you meant:
function Player() { this.speed = 5; this.x = 50; this.y = 50; }
Since your original code means that the variables speed, x, and y are local and
therefore dead at the point where you call setObject().

JSValue has this API:
JSValue::get(ExecState*, PropertyName)
So, jf you have "JSValue p" then you can do something like:
JSValue x = p.get(exec, Identifier(exec, "x"))
Where "exec" is an ExecState* or CallFrame* that you have lying around. If
you're in the C++ code for your setObject(), then presumably someone is passing
you one of those things, somehow.
