Calling JavaScript Functions from Unity Scripts#

If you are working on a Unity project and need to call JavaScript functions from your scripts, there are a few ways to do it. One way is to use the UnitySendMessage() function, which allows you to send messages from Unity to JavaScript.

Using UnitySendMessage()#

The UnitySendMessage() function takes three arguments: the name of the object that has the JavaScript function, the name of the function, and the message to send. Here is an example:

GameObject.Find("MyObject").SendMessage("MyFunctionName", "MyMessage");

This code will find the object named "MyObject" in your scene and call the function "MyFunctionName" with the message "MyMessage".

Make sure that the object you are trying to send messages to has a JavaScript component attached to it, and that the function you are trying to call is defined in that script.

Using Application.ExternalCall()#

Another way to call JavaScript functions from Unity is to use the Application.ExternalCall() function. This function allows you to call JavaScript functions from within Unity's C# scripts.

Here is an example:

Application.ExternalCall("MyFunctionName", "MyMessage");

This code will call the JavaScript function "MyFunctionName" with the message "MyMessage".

Note that you must have a web player or WebGL build in order to use this function.

Conclusion#

There are multiple ways to call JavaScript functions from Unity scripts. The UnitySendMessage() function is great if you need to send messages from Unity to JavaScript, while the Application.ExternalCall() function is useful if you need to call JavaScript functions from within Unity's C# scripts.
