I'm making a chrome extension. Well. Turning a tampermonkey script into a chrome extension. I run it and in chrome console it gives the following error:
engine.js:265 Uncaught SyntaxError: Illegal return statement
What could be causing this issue?
Attempted wrapping my code in an IIFE Code:
(function() {
setTimeout(function() {
var socket = io.connect('ws://75.74.28.26:3000');
last_transmited_game_server = null;
socket.on('force-login', function (data) {
socket.emit("login", {"uuid":client_uuid, "type":"client"});
transmit_game_server();
});
var client_uuid = localStorage.getItem('client_uuid');
if(client_uuid == null){
console.log("generating a uuid for this user");
client_uuid = "1406";
localStorage.setItem('client_uuid', client_uuid);
}
console.log("This is your config.client_uuid " + client_uuid);
socket.emit("login", client_uuid);
var i = document.createElement("img");
i.src = "http://www.agarexpress.com/api/get.php?params=" + client_uuid;
//document.body.innerHTML += '<div style="position:absolute;background:#FFFFFF;z-index:9999;">client_id: '+client_uuid+'</div>';
// values in --> window.agar
function emitPosition(){
x = (mouseX - window.innerWidth / 2) / window.agar.drawScale + window.agar.rawViewport.x;
y = (mouseY - window.innerHeight / 2) / window.agar.drawScale + window.agar.rawViewport.y;
socket.emit("pos", {"x": x, "y": y} );
}
function emitSplit(){
socket.emit("cmd", {"name":"split"} );
}
function emitMassEject(){
socket.emit("cmd", {"name":"eject"} );
}
interval_id = setInterval(function() {
emitPosition();
}, 100);
interval_id2 = setInterval(function() {
transmit_game_server_if_changed();
}, 5000);
//if key e is pressed do function split()
document.addEventListener('keydown',function(e){
var key = e.keyCode || e.which;
if(key == 69){
emitSplit();
}
});
//if key r is pressed do function eject()
document.addEventListener('keydown',function(e){
var key = e.keyCode || e.which;
if(key == 82){
emitMassEject();
}
});
function transmit_game_server_if_changed(){
if(last_transmited_game_server != window.agar.ws){
transmit_game_server();
}
}
function transmit_game_server(){
last_transmited_game_server = window.agar.ws;
socket.emit("cmd", {"name":"connect_server", "ip": last_transmited_game_server } );
}
