Forced to use Function/Field ID when calling vanilla code

[Ruarc88]

Working on a simple mod for 1.9.4 to disable the ability for the player to be moved by other entities. Found that any call I make to vanilla code will only recognize a function/field ID instead of the function/field name. I've seen other posts on both sides of this, some using names while others use IDs. Is there a way to fix this and/or an easy way to find the ID without manually trying the hundred or so boolean fields and praying? Unfortunately the second you put ID in Google, all you get is block ID conflicts.

 

Using eclipse and forge 1968 (was on 1959).

I think he's trying to use Reflection and needs the SRG name.

This is what I need, thanks! Am I correct in assuming that for 1.9.4 I will need the snapshot dated the same as my current version of Forge (for best results)?
