ModAPI.util

ModAPI.util provides and exposes a large number of utilities for interacting with ModAPI.

Properties:

• StaticProps_ProxyConf: ProxyConfiguration
  • This is the proxy configuration used for exposing ModAPI.items, ModAPI.blocks, ModAPI.enchantments and ModAPI.materials
  • See: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Proxy/Proxy
• TeaVM_to_BaseData_ProxyConf: ProxyConfiguration
  • This is a non-recursive proxy config for removing prefixes from java objects.
• TeaVM_to_Recursive_BaseData_ProxyConf: ProxyConfiguration
  • This is a recursive proxy config for removing prefixes from java objects. It handles properties (both object and array) as well as function outputs. Used for ModAPI.player, ModAPI.mc, ModAPI.world, ModAPI.network and more.
• TeaVMArray_To_Recursive_BaseData_ProxyConf: ProxyConfiguration
  • This is a recursive proxy config for handling arrays from TeaVM_to_Recursive_BaseData_ProxyConf

Methods:

• ModAPI.util.str(jsString: String) : java.lang.String
  • Converts a javascript string to a java string, for use in java methods and constructors.
  • Alias: ModAPI.util.string()
• ModAPI.util.unstr(jclString: java.lang.String) : String
  • Converts a java string to a javascript string.
  • Alias: ModAPI.util.ustr()
  • Alias: ModAPI.util.unstring()
  • Alias: ModAPI.util.jclStrToJsStr()
• ModAPI.util.getMethodFromPackage(classId: String, methodName: String) : String
  • Takes a class id (eg: net.minecraft.client.Minecraft) and a method name (eg: middleClickMouse) and returns its key in ModAPI.hooks.methods.
• ModAPI.util.stringToUint16Array(string: String) : Uint16Array
  • Encodes a string into a uint16array.
• ModAPI.util.setStringContent(jclString: java.lang.String, contents: String) : void
  • Writes a new javascript string into the contents of a java string.
• ModAPI.util.getMethodFromPackage(classId: String, methodName: String) : String
  • Takes a class id (eg: net.minecraft.client.Minecraft) and a method name (eg: middleClickMouse) and returns its key in ModAPI.hooks.methods.
• ModAPI.util.hashCode(string: String) : String
  • Returns the hash of a string.
• ModAPI.util.isCritical() : boolean
  • Checks wether the thread is in a critical state.
  • When patching methods, it is good practice to allow the method to resume as usual if this is true, to avoid stack implosions. (yes, those are real)
• ModAPI.util.createArray(class, jsArray) : Object[]
  • Makes a java array from a class and a javascript array.
  • The class parameter can be retrieved via reflect: ModAPI.reflect.getClassById("net.minecraft.util.BlockPos").class
• ModAPI.util.wrap(obj: Object) : object
  • Returns a wrapper around native java objects, removing prefixes and fixing method outputs.
• ModAPI.util.getNearestProperty(object: Object, property: string) : string
  • Finds the nearest property name to the one you specify (suffix based). This is used to mitigate teavm adding random suffixes to properties.
• ModAPI.util.modifyFunction(fn: Function, patcherFunction: Function) : string
  • Returns a modifies version of a function, where the patcher function can be used to modify the contents of a function. Example:

    function add(a, b) {
      return a + b;
    }
    var multiply = ModAPI.util.modifyFunction(add, (code)=>{
      return code.replaceAll("a + b", "a * b");
    });
    console.log(multiply(2, 3));
    //Logs 6
