I've got a class Robot as defined below. But for some reason there's an error with the processCommand function and I can't figure out what it is. It's the only function that takes a parameter so I'm wondering if there's something wrong with the way I pass it in the readCommands function?
Any help or opinion is appreciated!
function Robot(pos){
this.pos = pos;
this.language;
this.printCoords = function(){}
this.setLanguage = function() {}
this.setPos = function() {}
this.processCommand = function(s){
var direction = this.pos[2];
direction = direction.replace(" ", "");
if( (s.match('V') && this.language.match("svenska")) ||
(s.match('L') && this.language.match("engelska")) ){
switch(direction){
case "N":
// Look West
this.pos[2] = " W";
break;
case "E":
// Look North
this.pos[2] = " N";
break;
case "S":
// Look East
this.pos[2] = " E";
break;
case "W":
// Look South
this.pos[2] = " S";
break;
default:
break;
}
}
else if( (s.match('H') && this.language.match("svenska")) ||
(s.match('R') && this.language.match("engelska")) ){
switch(direction){
case "N":
// Look East
this.pos[2] = " E";
break;
case "E":
// Look South
this.pos[2] = " S";
break;
case "S":
// Look West
this.pos[2] = " W";
break;
case "W":
// Look North
this.pos[2] = " N";
break;
default:
break;
}
}
else if( (s.match('G') && this.language.match("svenska")) ||
(s.match('F') && this.language.match("engelska"))){
switch(direction){
case "N":
// Walk North
this.pos[1] += 1;
break;
case "E":
// Walk East
this.pos[0] += 1;
break;
case "S":
// Walk South
this.pos[1] -= 1;
break;
case "W":
// Walk West
this.pos[0] -= 1;
break;
default:
break;
}
}
this.printCoords();
}
this.readCommands = function() {
document.getElementById("textField").onkeyup = function(key){
key = window.event;
keyCode = key.keyCode || key.which;
if(keyCode == '13'){
var commandString = document.getElementById("textField").value;
for(var i = 0; i < commandString.length; i++){
this.processCommand(commandString[i]);
}
}
}
}
}
I believe your event handler, (function(key){}) isn't doing what you want it to do.
This is because in the context of an event handler invocation, this usually refers to the DOM element on which the event occurred, not the instance of Robot.
Try this code instead:
this.readCommands = function() {
var that = this;
document.getElementById("textField").onkeyup = function(key){
key = window.event;
keyCode = key.keyCode || key.which;
if(keyCode == '13'){
var commandString = document.getElementById("textField").value;
for(var i = 0; i < commandString.length; i++){
that.processCommand(commandString[i]);
}
}
}
}
This way, you store a reference to the actual object you want to call the method processCommand() on, and can invoke it in the event handler.
using the old that=this trick:
function Robot(pos){
this.pos = pos;
this.language;
this.printCoords = function(){}
this.setLanguage = function() {}
this.setPos = function() {}
this.processCommand = function(s){
var direction = this.pos[2];
direction = direction.replace(" ", "");
if( (s.match('V') && this.language.match("svenska")) ||
(s.match('L') && this.language.match("engelska")) ){
switch(direction){
case "N":
// Look West
this.pos[2] = " W";
break;
case "E":
// Look North
this.pos[2] = " N";
break;
case "S":
// Look East
this.pos[2] = " E";
break;
case "W":
// Look South
this.pos[2] = " S";
break;
default:
break;
}
}
else if( (s.match('H') && this.language.match("svenska")) ||
(s.match('R') && this.language.match("engelska")) ){
switch(direction){
case "N":
// Look East
this.pos[2] = " E";
break;
case "E":
// Look South
this.pos[2] = " S";
break;
case "S":
// Look West
this.pos[2] = " W";
break;
case "W":
// Look North
this.pos[2] = " N";
break;
default:
break;
}
}
else if( (s.match('G') && this.language.match("svenska")) ||
(s.match('F') && this.language.match("engelska"))){
switch(direction){
case "N":
// Walk North
this.pos[1] += 1;
break;
case "E":
// Walk East
this.pos[0] += 1;
break;
case "S":
// Walk South
this.pos[1] -= 1;
break;
case "W":
// Walk West
this.pos[0] -= 1;
break;
default:
break;
}
}
this.printCoords();
}
var that=this;
this.readCommands = function() {
document.getElementById("textField").onkeyup = function(key){
key = window.event;
keyCode = key.keyCode || key.which;
if(keyCode == '13'){
var commandString = document.getElementById("textField").value;
for(var i = 0; i < commandString.length; i++){
that.processCommand(commandString[i]);
}
}
}
}
}
That's a lot of code to quickly glance at and surmise an answer. But, this errors are typically a result of this not having the value you think it should.
It's important to recognize that the value of this changes based on the calling context of the function. A typical solution to solve errors like this is to store the value of this in a variable that can be referenced later, i.e.;
var self = this;
and then use self instead of this directly.

Happy holidays first of all.
I am unable to find the reason why I am unsuccessful at invoking the 'commands' function with its relative orders on this Javascript exercise. Have I messed up with the {}?

Any input/suggestion will be greatly appreciated. I can't seem to find the mistake and it is quite infuriating. However, thank you again and have a lovely and festive time!
You need one more closing brace } at the end of the moveBackward function. You closed the switch statement but not the function.
Happy Holidays!
function control()
{
var ship = document.getElementById("ship");
document.onkeydown = function(e) {
switch (e.keyCode) {
case 38:
ship.style.top += "5%";
break;
case 40:
ship.style.top -= "5%";
break;
default:
break;
}
}
}
setInterval(control,1000);
This code is not working.
The object I'm trying to move is not moving when I'm pressing the Up & Down Arrow Key.
You can't do
ship.style.top += "5%";
because ship.style.top value is not a number but a string. the += opérator is concatening strings here.
You should do something like that:
const ship = document.getElementById("ship");
document.onkeydown = function (e) {
let winHeigth = window.innerHeight;
let top = ship.style.top;
switch (e.code) {
case "ArrowUp":
ship.style.top = (Number(top.substring(0, top.length - 2)) - (winHeigth / 20)) + "px";
break;
case "ArrowDown":
ship.style.top = (Number(top.substring(0, top.length - 2)) + (winHeigth / 20)) + "px";
break;
default:
break;
}
}
The position attribute of the "ship" must be like "relative".
By the way, e.keyCode is deprecated, you can use e.code instead ^^
I'm back again, just as stumped as ever... I have gotten further with my game, but looking back at one part of the game, I have a check to see if you have potions, and if you do, and you try to use it, it calculates whether the current health and the added amount from the potion is more than the max health of the player. If it is then it tells you you cannot drink it, and if it isn't, then it lets you drink it. And then if you don't have any potions and you try to use it, then it tells you you don't have any.
The part I am having issue with, is that it is running twice, and I am not sure why. Here is a snippet of the Switch Statement:
while (currentarea == "Hero's Turn") {
if (hTurn == true) {
switch (classType) {
case "Warrior":
case "Archer":
switch (input) {
case "punch":
case "p":
Punch();
break;
case "kick":
case "k":
Kick();
break;
case "attack":
case "a":
Attack();
break;
case "health potion":
case "h":
HealthPotion();
break;
default:
}
case "Mage":
switch (input) {
case "fire":
case "f":
FireMagic();
break;
case "wind":
case "w":
WindMagic();
break;
case "frost":
case "c":
IceMagic();
break;
case "health potion":
case "h":
HealthPotion();
break;
case "mana potion":
case "m":
ManaPotion();
break;
default:
}
default:
}
return;
}
}
I tried to move the Archer to its own line and that just made it run three times. The issue is with the Warrior and Archer, the Mage only pushes the info once as intended.
This is the code for the function:
function HealthPotion() {
if (healthPotion.AmountOf < 1) {
$("<p>Sorry, you don't have any more of those.</p>").hide().insertBefore("#placeholder").fadeIn(1000);
checkH();
return;
}
if (healthPotion.AmountOf != 0) {
if(battleHealth + healthPotion.Health <= maxHealth) {
$("<p>You regained some Health! You regained " + healthPotion.Health + " HP!</p>").hide().insertBefore("#placeholder").fadeIn(1000);
battleHealth += healthPotion.Health;
document.getElementById("battleHealth").innerHTML = battleHealth;
healthPotion.AmountOf--;
document.getElementById("healthPotion.AmountOf").innerHTML = healthPotion.AmountOf;
checkE();
return;
}
else {
$("<p>Your health isn't damaged enough for that! It would be a waste to use that right now.<br />Press enter to carry on.</p>").hide().insertBefore("#placeholder").fadeIn(1000);
checkH();
return;
}
}
}
Here is how I have the potion constructed:
var healthPotion = { //Recovers battle HP.
Name: "Health Potion",
Health: 20,
AmountOf: 5,
Value: 30,
}
This is where the loops go to (the enemy and the hero check):
function checkE() {
if (eHealth >= 1) {
currentarea = "Enemy's Turn";
document.getElementById("currentarea").innerHTML = currentarea;
hTurn = false;
eTurn = true;
return;
}
else if (eHealth <= 0) {
eHealth = 0;
document.getElementById("eHealth").innerHTML = eHealth;
currentarea = "Death";
win++;
document.getElementById("win").innerHTML = win;
hTurn = false;
eTurn = false;
return;
}
}
function checkH() {
if (battleHealth >= 1) {
currentarea = "Battle";
document.getElementById("currentarea").innerHTML = currentarea;
eTurn = false;
hTurn = true;
return;
}
else if (battleHealth <= 0) {
battleHealth = 0;
document.getElementById("battleHealth").innerHTML = battleHealth;
currentarea = "Death";
document.getElementById("currentarea").innerHTML = currentarea;
lose++;
document.getElementById("lose").innerHTML = lose;
return;
}
}
At this point I am completely stumped, as I have switch statements and nested functions in all of my coding at this point, but this is the only area I am seeing this issue.
My main browser is Firefox, but I I tested on Chrome and Edge, which both have the same results. IE will not play my game, mainly because I haven't coded it to do so yet.
I looked around at other's questions before posting here, and didn't see anything that matched up to this particular issue.
Looking in the Admin Console of each browser, no error was thrown, just the multiple lines of repeated verbage.
If you keep playing and taking damage enough to use the potion, you see this:
You break out of the inner switch, that break does nothing for the outer switch so when you have "Warrior" it does that case and since there is no break at its level, it goes to "Mage"
switch (classType) {
case "Warrior":
case "Archer":
switch (input) {
case "punch":
case "p":
Punch();
break;
case "kick":
case "k":
Kick();
break;
case "attack":
case "a":
Attack();
break;
case "health potion":
case "h":
HealthPotion();
break;
default:
}
break; // <-- YOU NEED THIS HERE
case "Mage":
switch (input) {
case "fire":
case "f":
FireMagic();
break;
case "wind":
case "w":
WindMagic();
break;
case "frost":
case "c":
IceMagic();
break;
case "health potion":
case "h":
HealthPotion();
break;
case "mana potion":
case "m":
ManaPotion();
break;
default:
}
break; // <-- YOU NEED THIS HERE IF YOU DO SOMETHING IN DEFAULT
default:
}
While re creating a game in the style of ZORK recently, I have come across a problem and have no idea what is causing it or how to deal with it.
I used a while loop on a prompt box, comparing the user input against a switch() case, and returning a response. I have been building on it for some time now and there is over 600 lines of JavaScript.
After adding a few more lines for another element of the game, I noticed that the script suddenly quit in the middle of using it (meaning that the prompt did not show again.) This had not ever happened before with any previous versions, and I triple checked for errors, but could not find any. I looked up JavaScript limitations on certain browsers and it said that 5,000,000 was the maximum allowed statements. I did not think that only 600 lines, even looping, could amount to that much after only a minute or two of usage.
So I am stumped. I don't know what is causing this problem or how to fix it or work around it. I ran it through a js minifier and got the same result as before.

You really should learn to use the console in your browser. I just played it for a little bit with the console open, and got an error:
Uncaught ReferenceError: reppS is not defined
In your computePwr function, you have a variable named repS, but one time you typed it as reppS.
repS = reppS + 60;
Corrected:
repS = repS + 60;
Next time, you should check your console. You could also run your code through jslint, which will catch simple typos and other errors.
I'm programming something withe Javascript which captures keyboard input, but the problem is that every time the user presses a key there an error sound. How can I disable it?
