Hi KnackwurstBagel,

Thanks for this explanation, this has been very detailed and helpful.  I've seen a few of the prototypes around and always tried treating them like a function and therefore could never get them working.  Thanks for steering me in the right direction.

Cheers.

Hi, i'm extremely new to javascript and therefore am probably asking a stupid question, but can you explain how you would call your function from within main?

So far, I've created a module called 'logs.test' and copied your code into this module.

from within main I can't seem to work out how to successfully call it and was hoping you could help?

All I see within the console is "Testing this function: undefined"

[main]

var Test = require('logs.test');

module.exports.loop = function () {

    console.log('Testing this function: ' + Test());

...

}

[/main]

[logs.test]

module.exports = function(){
Room.prototype.stats = function(){

var foes = this.find(FIND_HOSTILE_CREEPS, {
filter: function(object) {
return object.getActiveBodyparts(ATTACK) == 0;
}
});

if (foes.length > 0){
return {
hostiles: foes,
numHostiles: foes.length,
hostileUser: foes[0].owner.username
};
} else {
return {
hostiles: foes,
numHostiles: 0,
hostileUser: undefined
}
}
}
};

[/logs.test]
