[1.15.2] How to edit raw vanilla code with forge

[KdotDevelopment]

I used mcp-reborn but i could not figure out how to make a proper json for the version file.

 

Anyway, before you respond that editing vanilla code is dead, i need you to realize that this is the only way to do it. I want to make all barriers visible even if you arent holding the item. I sucessfully made it in mcp, but building the jar didnt work properly and i dont know how to make a json for the version.

 

So if you know how i can either edit the vanilla code using forge or import the code I already wrote in MCP, please respond.

 

Edit: im new to this forums so this may be in the wrong place. Thanks!

You don't. Specifically.

Modifying vanilla isn't supported on these forums.

 

In your case, modifying vanilla code isn't even necessary (People always say "my case definitely need a core mod", but it is in fact not needed in 99% of their case. You just have to be creative with the system ).

Simply replace the barrier renderer with your own implementation.

Well, i already made the whole mod from just vanilla code, i was just wondering if I could port it over to forge so I can actually make it run. And if you wouldnt mind, could you explain how I could do this without modifying the vanilla code?

Depends. If all you did is created a rendering method that would integrate well into Forge's event driven system, then yes.

In vanilla Minecraft, barriers are rendered as particles, and handled inside ClientWorld. This might sound impossible, however you could replace the barrier block itself by overriding the registry and its entry in the Blocks class. After that, you have control over the full block. Simply use a TESR or subscribe to RenderWorldLastEvent and render the barrier sprite or emit the vanilla barrier particle in the block.

 

If you feel like replacing the block entry may cause incompatibilities, you can also subscribe to RenderWorldLastEvent and render the barrier sprite at the vanilla barrier blocks (or use vanilla particles); however, this method would require you to set up a system to record all the barrier blocks in the world.

What i did was find the little part that said "holdingBarrier &&" and removed it. I made an abstract option within video settings to toggle it on and off. As a bonus for myself, i created a creative tab just for the items you can only get with commands (like barriers and command blocks). Also, i didnt make this clear but I need it to work on multiplayer. I can definitely try overriding the block and use that event to show the particle. Im not too familiar with forge code, but forge has a lot of tutorials so it shouldnt be too hard to find. Thanks!

PS it may be impossible, but i still think my vanilla code can be injected somehow into forge. Whether this be overriding classes within a mod or overriding classes as a modified version of forge itself. Just an idea.

You can still do this with the method I described above. Add an if statement before the rendering to check for this option would work.

In Forge, you can create a new ItemGroup and add in the items by overriding ItemGroup#fill.

Overriding the registry on a specific side is fine as long as the entries still matches up with the server/client. I.e. the server and client can have completely different blocks under the entry "dirt block", but there will be no problem with the game; it would render as the block on the client, while certain server-side functions are handled by the server-side block under the same entry.

 

Note that overriding registry entries might cause incompatibilities (when 2 mods try to modify the same entry, only one mod will succeed). However it is still better in terms of compatibility than using a core mod as the former still respects the Forge system.
