$ref & $unref

the ref and out keywords in c# are used when passing references to variables or structures to methods in typescript, these keywords are not available, but in zepetoscript, you can achieve similar functionality using $ref and $unref true left unhandled content type left unhandled content type left unhandled content type left unhandled content type left unhandled content type left unhandled content type for the example, let's set up a scene as follows add a 3d object, cube, to the scene in the inspector for the added cube, click "add component" and add a rigidbody add an empty gameobject to the scene write the refsample script below and add it to the gameobject created in step 3 import { gameobject, rigidbody } from 'unityengine' import { zepetoscriptbehaviour } from 'zepeto script' import testscript from ' /testscript'; export default class refsample extends zepetoscriptbehaviour { start() { // get the gameobject named "cube" const testobject = gameobject find("cube"); // get the rigidbody component from the "cube" object const testcomponent = gameobject find("cube") getcomponent\<rigidbody>(); // get the testscript component from the "cube" object const testscript = gameobject find("cube") getcomponent\<testscript>(); // create references to the components and object let tempobj = $ref(testobject); let tempcomponent = $ref(testcomponent); let tempscript = $ref(testscript); // check if the rigidbody component is not null if(tempcomponent != null) { // access the actual value of that reference let component = $unref(tempcomponent); console log(`component name ${component}`); } // check if the testscript component is not null if(tempscript != null) { // access the actual value of that reference let script = $unref(tempscript); script dotest(); } // check if the gameobject reference is not null if(tempobj != null) { // access the actual value of that reference let objname = $unref(tempobj); console log(`tempobj name ${objname name}`); } } } create another zepetoscript and write the testscript below import { zepetoscriptbehaviour } from 'zepeto script' export default class testscript extends zepetoscriptbehaviour { dotest() { console log(`testscript's dotest() is executed `); } } drag and connect testscript to the cube's inspector click the \[▶︎(play)] button to observe the results you can check the success of referencing objects, rigidbody components, and zepetoscript components in the console log window
