SendMessage with array paramter in unity webgl

Question

Unity SendMessage can only pass one parameter and it can be an array. So i am calling my sendMessage for javascript and calling C# method(acutally webgl method)

var arr = [x,y,z];
gameInstance.SendMessage("Cube","SetGameObjectPosition",arr);

but getting this error

Invoking error handler due to

Answer 1

From the SendMessage Docu

SendMessage(objectName, methodName, value);

Where objectName is the name of an object in your scene; methodName is the name of a method in the script, currently attached to that object; value can be a string, a number, or can be empty.

-> no it can not be an array

But it seems you want to pass on a position so as a workaround you could pass in the string like "2,2,2" and use

string[] numberStrings = ("2,2,2").Split(",");
float x = float.TryParse(numberStrings[0], out x) ? x : 0;
float y = float.TryParse(numberStrings[1], out y) ? y : 0;
float z = float.TryParse(numberStrings[2], out z) ? z : 0;

or something like that
