   - 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:
+  ```javascript
+    function add(a, b) {
+      return a + b;
+    }
