pls give me sourcecode…

function DoubleJump()
{ Jump();

If you want help with scripting you really need to at least make the effort of typing a question that is understandable. Have a look here.

If you post your current code I’m sure someone will help you out with a neat double jump. Although keep in mind this is not a place where you can order scripts, that is what a hired programmer will do for you.

Unity Answers is not a site where you can request source code.

@gregzo atleast before submit ur code try to run ,either this code run or not. dont waste time.
