JsBridge.unity

A small snippet that replaces SendMessage in Unity+WebGL.

Why

SendMessage is the only way to invoke C# functions from Javascript.
However, it's totally unusable because...

SendMessage can't return a value. So there's no official way to retrive values from Unity to Javascript.
SendMessage can have only one parameter. Even worse, it only accepts int, string and null.

JsBridge.Call("Sum", {a: 10, b: 20}, (result) => {
  console.log("10 + 20 = " + result);
});

JsBridge.Add("Sum", MySum);

struct MySumReqeust {
  public int a;
  public int b;
};
private int MySum(MySumRequest p) {
  return p.a + p.b;
}

If you think this is infficient, try this way:

private int MySum(Dictionary<string, int> p) {
  return p["a"] + p["b"];
}

Since C# is a strongly typed language, you have to make some effors for it.
C# is not a JS.
