| + | ====== TB.TEST_Count() ====== | ||
| + | |||
| + | In Hollywood there is a native function that returns how many items are stored into a table, it is **ListItem()**, however this function works only with tables indexed by numeric (and consecutive) values, starting from 0. | ||
| + | |||
| + | The **TB.Count()** function is able to count every table, even the ones with strings as index. | ||
| + | |||
| + | <code> | ||
| + | Local items = { [0] = 43, | ||
| + | [1] = 49, | ||
| + | [4] = 192, | ||
| + | music = "test.mp3" } | ||
| + | |||
| + | NPrint("TB.COUNT : ", TB.Count(items)) | ||
| + | NPrint("ListItems : ", ListItems(items)) | ||
| + | | ||
| + | NPrint("\nENTER TO QUIT") | ||
| + | InKeyStr(#ALL) | ||
| + | </code> | ||
| + | |||
| + | As you can see items are counted correctly using **TB.Count()**, even with mixed index types, while **ListItems()** stops at the first NIL index starting from 0. | ||
