    Why Isn't Text Showing

    Reply Quote
    Hello,

    I made a menu for my game, however, it is not showing the text on the scree. Here is my code. Sorry for making a similar post so soon after my other problem, but this for a different game.

    1 using System; 
    2 using System.Collections.Generic;

    Put a breakpoint on the text drawing code.  See if it's ever run.
    If it's not, why not?  See what variables are set to that cause it to be skipped.
    You have, basically, in a switch statement:
    "if (xxx) then DrawText()"
    So see what "xxx" equals.  Is it true?  If not, can it become true?  Do you ever set it to be true?
    You'll find the answer. ;)

    The position you're drawing your text is at:
    new Vector2(200, 1500 + 50 * i)

    What's the size of your game window, exactly? For some reason, I doubt it's 1650 pixels tall (1500 + 50 * 3), and it's probably not even 1500 pixels tall. Perhaps you meant to write 150 + 50 * i, rather than 1500? ;)

    Thank you, I had an extra zero in there. I changed it from 1500 to 150. It shows up now. Thanks again.
