Change variables in other script

Oke so I searched on internet for examples how to change variables in other scripts I just need a little bit more help to understand and to make it clear for myself.

I have this code:

Code (CSharp):

1. if (col.gameObject.name == "Grond")
2.         {
3.             Main Camera.GetComponent<Score>().leven --;
4.         }

This code is written in script 1 attached to the ball.
When the ball touch the ground I want the lifes from the script attaced to the main camera to decrease by one.
How do I write it down the right way because this one gives me a parsing error.

 

On phone atm. Can't check this.

That seems about right, but I'm not sure if you can write it like Main Camera with a space, unless this is some unity thing im not aware of.

I would try crearing a variable and then adding the camera to it and using it like

variable.GetComponent<script>().variableToChange--;

I might be wrong or there may be a better way, but give it a try.

 

Also on phone.

You need to use the reference to change the variable. What I would suggest is something like this:

Code (CSharp):

1. public BallScript bS;
2.  
3. void DoSomething ()
4. {
5. bS.HitGround();
6. }

Then just assign bS in the inspector to the ball script on the ball.

 

should be:

Code (CSharp):

1.         if (col.gameObject.name == "Grond")
2.         {
3.             Camera.main.transform.gameObject.GetComponent<Score>().leven --;
4.         }
5.
