If you struggle with the Tower - look here! :)

[JOHNNY GUEGGU]

Hi Guys

I had a fair amount of trouble getting the tower to work. I never programmed Javascript (or any other Object-Oriented language) before. Anyhow, I start getting the hang of this. :D

So for the attacking Part of the tower, you can just copy someone else's snippet. They are everywhere. I've gone with this one: http://support.screeps.com/hc/en-us/articles/203339002-Defending-your-room

The Building-Repairing is a bit more complicated, and code is vry hard to find. I had some inspiration here:
https://m.reddit.com/r/screeps/comments/4s6jrc/help_for_a_code_its_for_the_tower/?utm_source=mweb_redirect&compact=true

So I merged those two routines and learned enough in the process to write the third myself, the creep-healing part.

The code below does [In that order]:

- Defend your room and kill ANY hostiles that enter it, until the tower is EMPTY

- Heal any damaged creeps, until the tower is EMPTY

- If there are NO hostile creeps in the room, the tower repairs your buildings (But NOT the Walls or Ramparts - you can google the reasons) but only until the tower's energy is HALF gone. (You can tweak the value of course. ;) Because if you use up all your energy repairing stuff, and someone shows up at your door, you' have a problem. ;)

The advantages of the tower repairing / healing things are obvious:

-You need less repairer/healer creeps
- The tower repairs/heals more efficient than creeps - he doesn't have to travel! :)

This being said, I am still in a Novice Zone. As soon as the gloves are off, I'll deactivate that repairer-function I guess, just to be ready.

And I'll probarbly add a cooldown value after the tower attacked a hostile, so that in case the attack pasuses for a moment, the tower doesn't get drained healing/repairing stuff.

EDIT: The previous code had a bug in it when you had more than 1 tower.
I updated the code below. Now, you cna use several towers and everything works.

module.exports = {

    //TOWER CODE
    defendMyRoom: function(myRoomName) {

        /*  
        
        ORIGINAL TOWER CODE

        //TOWER CODE
        var towers = Game.rooms.W61S27.find(FIND_STRUCTURES, {filter: (s) => s.structureType == STRUCTURE_TOWER});
        for (let tower of towers) {
            var target = tower.pos.findClosestByRange(FIND_HOSTILE_CREEPS);
            if (target != undefined) {
                tower.attack(target);
            }
        }
        
        */
    
        var hostiles = Game.rooms[myRoomName].find(FIND_HOSTILE_CREEPS);
        var towers = Game.rooms[myRoomName].find(FIND_MY_STRUCTURES, {filter: {structureType: STRUCTURE_TOWER}});

        //if there are hostiles - attakc them    
        if(hostiles.length > 0) {
            var username = hostiles[0].owner.username;
            Game.notify(`User ${username} spotted in room ${myRoomName}`);
            towers.forEach(tower => tower.attack(hostiles[0]));
            console.log("ALERT!!!! WE ARE UNDER ATTACK!!!!! ALERT!!!! WE ARE UNDER ATTACK!!!!! ALERT!!!! WE ARE UNDER ATTACK!!!!! ALERT!!!! WE ARE UNDER ATTACK!!!!! ");
        }

        //if there are no hostiles....
        if(hostiles.length === 0) {
            
            //....first heal any damaged creeps
            for (let name in Game.creeps) {
                // get the creep object
                var creep = Game.creeps[name];
                if (creep.hits < creep.hitsMax) {
                    towers.forEach(tower => tower.heal(creep));
                    console.log("Tower is healing Creeps.");
                }
            }        
        
           for(var i in towers){
                //...repair Buildings! :) But ONLY until HALF the energy of the tower is gone.
                //Because we don't want to be exposed if something shows up at our door :)
                if(towers.energy > ((towers.energyCapacity / 10)* 9)){

                    //Find the closest damaged Structure
                    var closestDamagedStructure = towers.pos.findClosestByRange(FIND_STRUCTURES, {filter: (s) => s.hits < s.hitsMax && s.structureType != STRUCTURE_WALL && s.structureType != STRUCTURE_RAMPART});
    	            if(closestDamagedStructure) {
    	 	            towers.repair(closestDamagedStructure);
    	 	            console.log("The tower is repairing buildings.");
                    }
                }
            }
            
        }
    }
};

I came here trying to figure this out.. I am thinking using the function created above similarly to how the tutorial does run(creep)
