Questions & Answers

ok so im following the roll a ball Tutorial and everything is so easy but
when i got to the move the player section the scripts he wrote didnt work for me the console in unity told me that the script is unknow i copied exactly what the Tutorial said i over looked the Tutorial so many times and i cant find anything i did wrong here is the script im suing c#

rigidbody.AddForce(movement);

the console tries to correct the rigidbody to Rigidbody and when it does other errors occurs
also here what the console is telling me

Assets/scripts/controlermode.cs(13,25): error CS1525: Unexpected symbol `rigidbody’

this is where i got the script from this tutorial http://unity3d.com/learn/tutorials/projects/roll-a-ball/moving-the-player
what should i do ?? did the script change from unity 4 to 5? cause the tutorial says its using 4.6 not 5

Removed quick property accessors, like
.rigidBody, .rigidbody2D, .camera,
.light, .animation, .constantForce,
.renderer, .audio, .networkView,
.guiTexture, .collider, .collider2D,
.particleSystem, .particleEmitter,
.guiText, .hingeJoint for
modularization. Instead, use
GetComponent to get references.

https://unity3d.com/unity/whats-new/unity-5.0:

You need to get the component yourself:

GetComponent<Rigidbody>().AddForce(movement);

‘rigidbody’ was deprecated and removed. Replace with ‘GetComponent()’. Ex:

GetComponent<Rigidbody>().AddForce (movement * speed * Time.deltaTime);

Consider watching the scripting tutorial on get component.

I would also recommend looking through any of these that seem unfamiliar. They explain each topic a little more thoroughly than the tutorial projects.
