tnx im not very familler with hex editing
but i will cheak

im want to add some value to original fnt
its possible with your template?

in sime fnt file your temple give me this error

in sime fnt file your temple give me this error
Annotation 2020-04-13 153319.png

Your file is only 1620 bytes, of course, it will be wrong, it is not complete, it is offset at 0x59, and the data size of chunk4 is 0x3c8c (15500). So this is not a template error, it is yours.

Here is an example, I only added 2 characters manually: 可能.

fnt part:
chunk4 is a character information table.
at offset 0x59:
change chunkDataSize 8680 to 8720.
Because the one-letter information table occupies 20 bytes.

at offset 0x2245:(the chunk4 end offset)
insert 40 bytes.
re-run binary template.
In the template, go to the end of CHUNK4 and find the newly added 2 pieces of data. You will find that all are 0. We enter the relevant data in the template.


You will find that it has been added correctly.

dds part：

Use the reference line function of PS to obtain the relevant coordinate data and input it into the fnt file. Save the new DDS font.
Note**: save 32bpp format.

char part:
Save the character you want to add as UNICODE text, and then open it with a hex editor, excluding the BOM header 2 bytes, the remaining bytes every 2 bytes is an encoding.

tnx for this good guide
only one more Question
I need to increase the size of the dds file to 1024x1024 to add all my character to it
after that i need to edit all char location again then after that add my char to fnt?

[Allen]

If you expand the picture, if the original characters are still in the original position, then you do not need to change all the characters, only need to care about your newly added characters.
Because the coordinate value is an absolute value, no matter how you extend it, it will not be disturbed.

In CHUNK2 you need to modify the corresponding width and height information.

tnx man
you really saved me

Is there no way to automate the process of changing values?
i need to change values in 10 file, And doing all this manually takes a long time (very long)
I tried to do it manually
After an hour and a half, only 100 of the 433 completed (in one file)

I will write a tool for you. Yesterday I received your private message. You said that your new font was generated by BMFONT. I read the binary FNT format generated by BMFONT today. It turned out to be the same format as the game using fnt. That is to say, the format of the game is BMFONT. However, there are a lot of custom icons, so all we have to do is add new characters, not create new ones.

I will upload a tool later to add a new fnt index to the game's existing fnt file.
Don't forget the alpha channel when merging pictures, because the alpha channel determines which part of the character is displayed.

I will only support fnt binary files generated by BMFont v1.14beta64 version.
BMfont 64bit executable for v1.14 beta (1.65MB, 2019/11/15)
http://www.angelcode.com/products/bmfont/bmfont64.exe
v1.13 Can't run on my computer.

I have updated the format template.

Thank you very much
it seems that the only hard part is editing font that also contains icons ...
Other fonts can be Built directly with bmfont

[Allen]

This is a tool you can test, all values are generated based on BMFONT, except for the y value and the image height value, the other has not been modified. I just merge FNT files.

Thank you very much
Do I have to manually change these two values (y and height)? (add 512 to to all old cahr -y- value)
----edit----
i read your tool help, and now i understand everything
tnx man
