   Suddenly I am getting this error: "Warning: There was an OpenGL error: #1283" and it has brought my program to its knees. I've managed to trace it to the line where I register my bitmap font with SPTextField.

   [SPTextField registerBitmapFontFromFile:@"Font.fnt" texture:[[Game gameInstance].gameAtlas textureByName:@"Font_0"]];

   This line has remained the same for the past week or so, and it was working before lunch, but now it is not. The only thing that has changed is I added more characters to the bitmap font to account for more text coming into the game. Is there a limit to the number of characters that can be contained in a bitmap font?

   What are the new dimensions of [Game gameInstance].gameAtlas?

   The dimensions didn't change from the previous 512x512

   EDIT: I should clarify, that line alone doesn't cause it. It is only when I register the bitmap font and THEN USE IT. Using the bitmap font causes the overflow error.

   UPDATE: I have given up, and found another easy way to put a custom font onto an iPhone, so I will no longer need the bitmap font.

   Hm, really odd. Can you tell me how long the text was (roughly) that you were displaying? Perhaps you've hit the upper limit of the compiled sprites that the textfield is using internally.

   I didn't think of that! I recently added a new fairly long textfield (I don't have it in front of me now, but when I get to work I will check it). It's about 40 - 50 characters long for the Japanese version and 60 - 70 for English due to the added spaces. However, I'm pretty sure the problem still happened even when I commented out all the lines displaying the text...weird.

   Just as a side note, I work in Japan so I am using Japanese characters, not just standard Latin. For another note, this was on the simulator, NOT an actual device.

   Ok, the textfield is as follows:

   Japanese version - 115 chars(~73 unique by my rough count)
   English version - 203 chars(~35 unique)

   P.S. This font was imported at size 60, if that helps.

   OK, thanks for the information! Hm, well, 100-200 characters should be absolutely no problem normally. So I guess it has something to do with the fact that the characters are Japanese.

   If the problem is reproducible, say, in the Demo project (exchanging the font used there by yours), you can send it to me and I will have a look at it!

   It didn't reproduce in the Demo project, unfortunately. It's probably because I have so much else going on at once while I do it. It isn't an issue anymore because I used Cocoa to load the actual font file now, and it was working fine for a long time and randomly broke. Well, just make a note of it in case someone else happens to have the same problem.

   OK -- anyway, thanks for reporting it! I'll keep my eyes open on that issue.
