{{DISPLAYTITLE:Get2DARowCount(string)}}__NOTOC__{{NWNEE}}
Returns the number of defined rows in the 2da s2DA.
<nwscript>
int Get2DARowCount(
    string s2DA
);
</nwscript>


====Parameters====

;s2DA
:The 2DA to check the number of defined rows in


====Description====

Returns the number of defined rows in the 2da s2DA.


====Remarks====

Returns 0 if the 2da isn't available; you can also check for a specific 2da in resman with [[ResManGetAliasFor]] or [[ResManFindPrefix]]. See [[Get2DAString]] for notes on 2da caching.

This is useful for looping entire 2da files with [[Get2DAString]]. You can also combine it with [[Get2DAColumn]] to inspect entire 2da contents dynamically.

Note that for large 2da files (extended in EE commonly) you can easily TOO_MANY_INSTRUCTIONS (TMI) on looping large amounts of 2da data. See [[GetScriptInstructionsRemaining]] for a way to avoid this.

====Example====

<nwscript>
// Example for Get2DARowCount
// 
// Get2DARowCount("racialtypes"); returns 30 rows, numbered 0 through 29.
// 
// In a for loop you need to use the row ID 0 - 29 not 1 - 30

int nRow;
int nTotalRows = Get2DARowCount("racialtypes"); // 30

for(nRow = 0; nRow < nTotalRows; nRow++)
{
    // nRow goes from 0 to 29 as needed
}
</nwscript>
