Issue with Rigidbody2D

hello, I don't understand why this line doesn't work :

I'm watching a tutorial of how to create a little game and i want my png to jump ! but this is the first time I use code or even unity... so I quiet lost. thanks for your help !

 

You have to attach a rigidbody2D on you game object and in your script you need a reference of that rigidbody2D.

Code (JavaScript):

1.  
2.  
3. rig : Rigidbody2D;
4.  
5. function Start(){
6.     rig = GetComponent("Rigidbody2D");
7. }

For this example you can use addForce on rig in your update function.

 

I'd suggest doing the official unity tutorials if you aren't already. They will likely be more updated than others you may find.

 

Also the first warning is telling you that what you are coding in using obsolete code.
Check the new way of coding.

Just something I noticed in the error list
