Hi, I was programming my 1.12.2 mod, when I thought of a question.

 

field_71434_R is a field that determines if Minecraft has crashed I believe. (Unless if I am wrong).

 

If I were to use this field, would I do this in an if statement?

 

if (field_71434_R) {

	// Some Code Here

}

 

(Assuming field_71434_R means hasCrashed, which I think is boolean. Correct me if I am wrong)

Ok, is the information on how to use methods and fields on the wiki?

 

Like where do I find a website or wiki on how to use these fields or functions? (http://export.mcpbot.bspk.rs/)

Do you want the proper, renamed fields? Set up a decompWorkspace then. Currently, you're using the searge names, which are something like field_*****, param_*****, or method_*****.

I did set up decompWorkspace, however, field_71434_R  represents asCrashed, and when I type asCrashed into eclipse, it says its wrong.

This field has been named hasCrashed in the latest MCP mappings, so you should update your mappings to stable_39 (the final mappings version for 1.12). The MCPBot website you linked earlier explains what you need to change in your build.gradle to do this (click on the stable_39 dropdown button and then click "Use in ForgeGradle").

 

There's no wiki that explains what each field/method does, the closest thing would be the Javadocs of Vanilla fields/methods provided by MCP. These are included in the source code attached to the forgeSrc dependency when you run setupDecompWorkspace. Like field/method names, Javadocs are contributed by the community using MCPBot; so they may not always be 100% accurate or up-to-date.
