As stated above, you forgot the last two parameter required for the code to work.

-virtualworld : This parameter is the virtual world you want the TextLabel to show up in, use /world at the spot in game to see the current VW of your player

-testLOS : This parameter is used if you want the text label to show up behind objects. Either 0 or 1

Код:

 Create3DTextLabel("text", color, Float:X, Float:Y, Float:Z, Float:DrawDistance, virtualworld, testLOS);

So your code would be

Код:

Create3DTextLabel("Press 'F' to buy somthing",COLOR_RED,251.99, 117.36, 1003.22,4.0, virtualworld, 0);
