Need help starting the script tutorial

https://unity3d.com/learn/tutorials...cripts-as-behaviour-components?playlist=17117
I go to this first tutorial, which is changing the colors of the cube in the play screen.

I try to play it, but it says "All compiler errors have to be fixed before you can enter play mode!"
I get about 6 error messages.

But I take the script from below the video, I cut and paste! What more do I have to do?
-Before that, I assign the script to the cube, which I first add the rigid body component. And I put the plane under the cube.

What more can I do? I've watched the video, and I've cut and paste the code from below!

 

What errors do you see in the console?

 

Assets/ExampleBehaviorScript.cs(10,36): error CS0619: 'UnityEngine.GameObject.renderer' is obsolete: 'Property renderer has been deprecated. Use GetComponent<Renderer>()instead.(UnityUpgradable)'
Assets/ExampleBehaviorScript.cs(10,45): error CS1061: Type 'UnityEngine.Component' does not contain a definition for 'material' and no extension method 'material' of type 'UnityEngine.Component' could be found (are you missing a using directive or assembly reference?)

I'm not at my unity machine right now, if nobody chimes in by later I might test and see if it works for me. Another question - are you using unity 5?

 

Yes, it says its Unity 5.1.2f1 personal.

 

".renderer" is no longer a member of the GameObject class. It used to be a shortcut for calling GetComponent<Renderer>(), but now it isn't, so you need to use the GetComponent<Renderer>() call instead. It says this in the error pretty clearly, and it also states that it's upgradable. In your Unity menu if you go to "Assets -> Run API Updater" it should allow you to update all of those deprecated entries automatically.

 

I tried running API updater, it's disabled. Where is the GetComponent<Renderer>()? I tried ctrl ', but do you have a link?

 

If you double click the error, it'll open the script and take you to where the problem is occurring. When you get there, take the ".renderer" and replace it with "GetComponent<Renderer>()"- then go back and do the same thing for the remaining errors. I don't know what "ctrl ' " is supposed to be or what you're talking about with links, but if you want more info on the Renderer component you can find it here.

 

I got it to work! Here's my problem I've had: The script's name was "Colors", and the Public Class was named something else "Example Script". So, I changed the Public Class name to match the script name "Colors".

Problem solved. Thanks.
