Screeps: write debug output to console?

Question

Is there a way of getting screeps code to print strings to the console (or anywhere really) for simple debugging purposes?

Answer 1

You can use standard console.log method for that.

Answer 2

I use the following to print objects to the console:

console.log(JSON.stringify(<myVariable>))

Answer 3

I can't find how to do this in Docs. Had to write something like this:

module.exports = function () {
   var log = Memory.log;
   if(log === null || log === undefined){
       log = Memory.log = [];
   }

   var parts = ["["+Game.time+"]"];
   for(var i in arguments){
       parts.push(arguments[i]);
   }
   var msg = parts.join(" ");
   log.push(msg);
   if(log.length > 10){
       log.shift();
   }
}

Will be grateful if someone can provide a better solution.

Answer 4

Sometimes when you do console.log you get unhelpful string representations of objects, something like like "[Object]".

If you want to drill down into the object and check out it's properties, the easiest solution is to open your browser's console. The devs made it so any console.log in your script will also reach the standard browser console. I believe it works in all major browsers.
