What do you mean by nothing working? Are you getting any errors or is the image just not showing up?

My first thought was that the image might be loading asynchronously--I remember that happening in the past with Java--but I think that ImageIO avoids that issue.

My second thought is to make sure the image is loading. Within the try, just after the 'img = ...' line, try printing out the images width and height. If it gets the right numbers, you're on the right track at least.

Hello all!  Any suggestions of a good language/library/tutorial for making a MUD?  I'm familiar with C++ and Python.

[JanusTwoface]

Something that does as much of the underlying work (particularly the networking) as is possible. :) Writing an engine can be all sorts of fun, but it makes it far less likely that you'll ever actually finish anything.

Evennia might do what you want. It's an open-source Python framework for building MU* games. It looks a bit dense but powerful.

(Heck, now you've got me interested in writing one. :)

In the initialization, I test this method, and when I run it, it crashes, saying:

Code: [Select]

javax.imageio.IIOException: Can't read input file!This happens from the line inside the try statement which attempts to load the file.
And by nothing working, I mean that everything that I have tried did not work.

javax.imageio.IIOException: Can't read input file!This happens from the line inside the try statement which attempts to load the file.
And by nothing working, I mean that everything that I have tried did not work.

Third thought: The file doesn't exist or Java cannot find it. Make sure it's there with this:

Code: [Select]

System.out.println("File is readable: " + (new File(Garden.directory, path).canRead()));

As a side note, you should use the new File(parent, child) constructor to build paths just in case you want to run on non-Windows systems. It will fill in the path separator for you.

Third and a half thought: Make sure that the directory is set correctly. Since you're developing in Eclipse, the program will run in the project root by default, IIRC, so paths should be relative to that rather than the source or binary folders. (I think).

Fourth thought: Make sure that you're reading a supported file format. By default ImageIO can handle GIF, PNG, JPEG, BMP, and WBMP. You can check what's supported with ImageIO.getReaderFileSuffixes() or friends.

[Lost in Nowhere]

It's trying to read a .png that definitely exists.
Anyways, don't have much time now.
~ EDIT ~
Now that I have enough time to do this:

Code: [Select]

File is readable: false
javax.imageio.IIOException: Can't read input file!

Spoiler: Large image (click to show/hide)

I have no idea what I'm doing wrong.
~ EDIT 2 ~
Just discovered that the path I was using was missing a folder, so...
I was thinking the problem was some stupid little mistake (like this).
Really, that was the entire problem.

Hi everybody, I'm trying to practise some OOP in C# and I'm having a problem with calling a method. The code is a mess so I highlighted the parts that are giving errors. All the greened code is just there for temporary testing. I tried making the methods static but it only created new errors.

You should highlight the line where the error occurs .
It looks like you're calling a function that isn't static like this:
ClassName.memberfunction(). The proper way would be calling it by "ClassName instance = new ClassName(); instance.memberfunction();"

I've been writing a program in python using tkinter and I can't get it to recognize right mouse clicks.  It recognizes left mouse clicks and middle mouse clicks just fine.  Maybe it's a longshot, but anyone got suggestions what could be causing this?

Choise1 needs to be static if you're accessing it from a static function.

Can you post the code?  All I could say offhand is that <Button-2> is for the middle button and <Button-3> is for the right.

The event in question starts at line 265, change line 298 if you want to change between right and middle mouse button.  It could also be a problem with my system and will work fine for you, which is feedback I'd appreciate.
