i dont know if you mean "how do you make gooballs look different", or "how do you make new gooballs for your levels". if you man how do you make gooballs look different, you get a gooball goomod, and unzip it. then you edit the image. if you mean how to make a gooball with special properties,

you can check out addin file format or How to Make a Goomod Level if you need help making a level, customizing gooballs or making you own gooballs

I mean, changing the look of them in goo corp as a .goomod file that you install with gootool.

oh, then im pretty sure you change someone elses goomod to be a .zip, change the image file in it, thenchange the xml files to show your user instead of someone elses. so that gootoll dosent take it as the same thing. the gooballs should look like what you changed the image file to.

you could just create a goomod file but put new png in the overwrite directory

then, gootool overwrites the original images and the wog corp looks different

@madaco: it doesn't open when you change it to a .zip.
@grant: doesn't work. it says that that it is an invalid addin and it had an error opening the .zip file.

did you follow the addin file format?

the images need to be in a specific folder inside the zip file, in you case "override\res\balls\common\" to modify the common gooballs and "override\res\balls\Drained\" to modify the ones in world of goo corp

the images must also have the exact same name as the ones in the game and the .zip needs to be changed to a .goomod on the archive

yes, i know that. i was only talking about goocorp as an example (sorta) as to what i'm talking about. when i said that it had an error opening it i meant gootool had the error opening it.

ohhhhhhh, well the posts are kinda confusing, especially the first one

but as for gootool, the error may have a number of reasons
some info such as what the error says would be nice

but it may be a number of reasons:
-incorrect addin.xml file
-your using a mac (this happened with my level)
-you have incorrect spelling and or incorrect case(java is CasE sEnsiTiVe)
-a whole other bunch

1. I checked everything on the addin.xml file, it's all the right stuff.
2. I don't have a Mac.
3. Look at #1.
Also, do you know where the eye images are for "common"?

oh nvm. finished with addin! Now back to the .zip to .goomod problem. How do you change a file type without using notepad?

well the filename extension, .zip, is hidden by your os

on windows, open a explorer window, click on tools->folder options
then click view, and uncheck "Hide extensions for known file types"

then the zip file should have the extension in the filename and you can change it to .goomod

you can also now change a .goomod to a .zip to open it and see how other addins work

to hide the extention, just recheck the "Hide extensions for known file types"

on linux, i have no idea but it should be similar

also the eyes are not unique to common gooballs, changing them would change all the eyes of that type

they're in \res\balls\_generic

ok, that's why i'm saying this version is for demo only. Finished and uploaded! LOCK UP TOPIC, PLEASE

That was a little confusing...

If you have 7-zip you can right click and click extract here, the overide, merge, compile aand addin files will be wherever you were when you chose extract here

1. This was already taken care of.
2. I have 7-zip...and it was confusing!
3. sweet icon!

They need a tutorial section on GooFans
