    <p>I know this has already been answered..but I think there will be some roadblocks ahead for you if you code everything with private variables like the accepted answer. Usually to get a reference in Unity you need to have an object in the scene with the desired attached script. So first you would re-write the script:</p> <pre><code>public class AmmoCounter : MonoBehaviour { public int ammo; public GameObject _pistol; void Start( ){ ammo = _pistol.GetComponent&lt; Pistol &gt;( ); } void Update( ) { guiText.text = "Pistol: " + ammo + "/7"; } } </code></pre> <p>In the scene you want an object with the Pistol script attached, then in the editor ( inspector ) you should drag that object into the _Pistol slot. There are several reasons for doing this but two important ones are 1) You're shortening the code and referencing the script once ( the current answer is duplicating the reference ) and 2) Using GetComponentInChildren is inefficient; Unity searches through <em>every</em> game object underneath a parent to get your component. Thus, a direct object reference is better. Also using this type of object reference will save you several headaches in the future, most notably easy reference and making it easier to follow your own code in the future ( you can see the reference in the editor rather than looking through code -- trust me magical references can be a nightmare ).</p> <p>If you don't want to reference through objects read up on the static type in C#, this allows you to reference items without using GameObjects. However, static types are finicky creatures, so be careful and know what you're doing before using them</p> <p>edit: grammar</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
