Java 2D Game Programming Episode 7 - Font and Stuff

So... this video was something else. Basically, this video shows you how to make a font class based on a .png image file

[vater]

I don't know why but when I follow along, I ended with an error that says Exception in thread "GameThread" in 5 different spots in the code. 6 if you in include Is there any way you could help one on one?

[crew]

It doesnt work with any numbers or sumbols?
Whats the reason?

[crew]

You could do not remove "final" from BufferedImage because it will never be changed.
To avoid the error you could remove " = null " and initialize the BufferedImage in the constructor.

To everybody who also dont know why there dont space in the text u must do
x += xOffset;
y+ = yOffset;
out of
for(int i = 0; i < word.length(); i++) {
if(word.charAt(i) != 32) {
g.drawImage(f.getFont(word.charAt(i)), (int) x, (int) y, width, height, null);


}

Have a good Day :)

Muito obrigado! O melhor professor! Estou aprendendo muito!

[olivermetz]

i know this is a bit late lol but loving the series, Exception in thread "GameThread" x lies outside the raster, i know its due to it being bigger than the img but cant find where its going wrong?

[Donslayer]

How do space work for you? I had to explisit say that if charAt == 32, then x = 2; y= 7; But you have nothing, and it still works.

[serkanefe]

how can ı make my own letters ?is there any idea that which program can be usefull for me?

[lapnghiepshopee]

i get error : Exception in thread "GameThread" / by zero
at wLetter = FONTSHEET.getWidth() / w;
hLetter = FONTSHEET.getHeight() / h;

[amanthapa]

Exception in thread "Game Thread" java.lang .nullPointerException occurs even after making res as source

[beonoc]

What's the benefit of doing it this way over using a font file?

[zdenduk]

Hello, you figured out a way to do this with symbols as well?

[Therman]

the letters are still in a little blob for me. any ideas?

[thedemonicstaff]

Just right click on the variable, refactor, rename, it will fix everything instead of making you do everything individually.

[Rock-off]

I like your videos. Can you send me zelda font please?)

Whats wrong whit this code?
