UdonSharpDecompiler V1.5

VRChat World Script Decompiler.

v1.5 is inspired by snowman

BE AWARE

before decompile, you need disassemble it, here is UdonSharpDisassembler

Example Output

Original Code

using UdonSharp;
using UnityEngine;
using VRC.SDKBase;
using VRC.Udon;

public class Logic: UdonSharpBehaviour {

      }
    } else {
      Debug.Log("can this happening??");
      if (dt > 2.0 f) {
        Debug.Log("also for this??");
      }

the output maybe wrong due to no information of Game functions.

Simplified by AI

maybe wrong but its pretty much readable

void Func_8()
{
    float deltaTime = UnityEngine.Time.deltaTime;
    
    if (deltaTime > 0)
    {
        if (deltaTime > 3)
        {
            UnityEngine.Debug.Log("low fps!!!");
        }
        
        UnityEngine.Debug.Log("can this happening??");
        
        if (deltaTime > 2)
        {
            UnityEngine.Debug.Log("also for this??");
        }
        
        for (int i = 0; i < 100; i++)
        {
            UnityEngine.Debug.Log("now spamming you");
        }
        
        int x = 500;
        
        while (x > 0)
        {
            UnityEngine.Debug.Log("while now spamming you");
            x--;
        }
    }
}

it was simplified by https://codepal.ai/code-simplifier (not ad)

you can try set line 73 (m_bRequiredThisPtr) to true in Globals.h to get different output

TODO

optimize decompile output to make it generate more readable code.
