GUI Attributes
guiFile
This attribute defines the image file for the gui. An example of such a gui file is the gui/furnace.png in the minecraft.jar. If you want to use gui files from the minecraft.jar or from other mods, the given value has to start with a '/'. If the given value doesn't start with a '/', it will use the gui file from the mod's texture directory (the directory with the same name as the mod's directory). Texture files for this attribute go into the textures/guis directory of your mod.
Examples
// Default value furnace
// uses the furnace.png from the minecraft.jar
guiFile = "/gui/furnace.png";
// Default value crafting table
guiFile = "/gui/crafting.png";
// Default value chest
guiFile = "/gui/container.png";
// uses the myGui.png from the texture directory of your mod
guiFile = "myGui.png";
// uses the furnace.png from the minecraft.jar
guiFile = "/gui/furnace.png";
// Default value crafting table
guiFile = "/gui/crafting.png";
// Default value chest
guiFile = "/gui/container.png";
// uses the myGui.png from the texture directory of your mod
guiFile = "myGui.png";
