I'm a beginner modder and a concept seems to keep popping up due to its importance is reading the source code. I have also hear it being called "reverse engineering". Is there a guide or could someone help me not get lost in the giant sea that source code can be?

 

Additionally, I'm using eclipse by the way and it seems like the file search feature does not search stuff in external dependencies (where the minecraft source code is). Am I missing something?

 

Help would be greatly appreciated.

Thanks.

The code for minecraft entities, blocks, etc are all in forge, and that is on your computer. For external dependencies just look up their github.

 

If you don't know Java, or just an inexperienced programmer, diving into Forge with a complex idea isn't going to work out. Anyhow, implement something trivial, for example maybe a new zombie extension, to figure out the ins and outs of what you're working with.

Thanks for the reply!

 

My question was more like if anyone had some tips on how to use eclipse-related tools and general navigation things that make reverse engineering easier (like command clicking a method to go to its definition and that kind of stuff)

 

Thanks in advance!

The right-click menu is great.

Find references, open type hierarchy, navigate to definition and so on.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

      By Kxcnw · Posted

      I tried installing several mods that improves fps with other several gameplay mods that i have added previously and tested to be playable. But when I have added the new mods that improves the fps, Java crashes. (version is 1.20.1)   Here is the crash log:    ---- Minecraft Crash Report ---- // But it works on my machine.

      Java crashing when I make a new world with mods

      shader disabled when changing camera forge 1.16.5

      By RazorPlay · Posted

      I have created a mod which applies x shader to the player after consuming x item for a certain time, but if the player presses f5 to change the camera the shader stops working. The only way I have found to prevent the shader from being deactivated is to load it on all ticks until it is disabled but this greatly reduces the performance of the game. I have also tried to cancel the event of changing the camera but this is not cancelable. Any advice, I've been trying to solve this for several days 😵‍💫
