or when constructItem would directly write into field just PipeWrench = new ItemPipeWrench(getId('pipeWrench')) LinkTool2 = new ItemLinkTool(getId('linkTool2')) LinkTool = new ItemLinkTool(getId('linkTool'))

Hopefuly it will be more clear now: public class mod2 static ItemLinkTool static ItemLinkTool static ItemPipeWrench pipeWrench My english isn't great (but even in my native language I'd have problems explaining this), so I'm adding one more example. I'll take a look at the ASM library, but in the end I might end up using the string as an identifier for fields :/ There probably isn't anything like I want in Java itself. When I'm looking at it I probably wouldn't need a method to get a field's name, the Field instance (from field's 'code name') would suffice. PS: I'm not looking for a field's class/class name or getting Field from name in String. String fieldsName = *getFieldsName(linkTool)*
