'Better than having sex with a noob'

AS: KeyCode

So all of you know how to check if Space or Enter is pressed, by simply applying the following code:
if(Key.isDown(Key.SPACE))

But you have always wondered how to use WASD and 1 2 3. That's why I'm making this tutorial. It will teach you how to use different keys for your games, better than up down left right.

KeyCodes: How to use?

This is very simple and alike to other keys. Simply use:
if(Key.isDown(<keycode here>))

What are the keycodes?

Numbers

The following keycode are codes you need to use for all the numbers appearing on your keyboard: 1,2,3,4,5,6,7,8,9,0.
1 = 49.
2 = 50.
3 = 51.
4 = 52.
5 = 53.
6 = 54.
7 = 55.
8 = 56.
9 = 57.
0 = 58.

Example:
if(Key.isDown(50)){
trace("Yay!");
}

That would trace 'yay' if the key '2' is pressed.

KeyCodes: Alphabet

Now this is very simple, just like the numbers every letter of the alphabet has its own code.

a = 65
b = 66
c = 67
d = 68
e = 69
f = 70
g = 71
h = 72
i = 73
j = 74
k = 75
l = 76
m = 77
n = 78
o = 79
p = 80
q = 81
r = 82
s = 83
t = 84
u = 85
v = 86
w = 87
x = 88
y = 89
z = 90

Example:
if(Key.isDown(65)){
trace("You pressed 'A' ");
}

Output for if you press A:
You pressed 'A'

That's it, you're done.

Have a nice day.

Did you know 'i//' would divide the var i with itself? :D

[GustTheASGuy]

You hurt my feelings. ;o;

Alright, I'll get back to doing something useful then.

Good idea, I'll make a AS: // ;)

Great script Toast, you should of included this though (mini tut I'm about to post):

You can also easily make something happen when a key is released. By doing so you would use the keyUp method.
onClipEvent(keyUp){
//stuff
}
I don't see a need to explain that code, it is self explanatory, but what it does is register than when any key is released and not pressed, then you can add your actions so it tells something to do something.

How would I specify that for a certain key?

Simple, this is where variables come in. Simply make it so when a key is pressed, a variable is defined (use Toat's tutorial above).
For example:
onClipEvent(enterFrame){
up=0
if(Key.isDown(Key.UP)){
up=1
}
}
onClipEvent(keyUp){
if(up==1){
//stuff
}
}

That means that when you press the key UP, the variable 'up' is defined as 1. With that said, when any key is released and up is = to 1 (from when you pressed UP) then something happens.

So yeah that's pretty much it, sorry if what I said doesn't make much sense, I hope it did. I don't write tutorials much as you can tell, but hope that helps. It is a really good way for something to happen when you release a key.

Oh, great tutroial Toast, that will help a lot of n00bies :P

1) no it won't, because // is a comment line

2) i divided by itself is 1, hence it's fucking redundant anyway

Hehe, don't you understand...? :P

one thing i like to do in flash when dealing lots of keycodes is, i declare a variable = to the Key.isDown condition. id put this right below the start of the clipEvent

_global.a=Key.isDown(65)

then when i wanna use it i just say
if(a){}
its great when you use alot of ifs of the same kind(like for doubletap keys)

He didn't say it was more efficient, he said he liked to do that =/

how is that anymore efficient than if (Key.isDown(65)) { }

it's actually less efficient doing it that way.

why is it less efficient, because it has more lines?
well this way only checks if its down once, instead of checking over and over it just refers to the boolean. so i think it would bemore efficient. but when i tested it, i tried haveing like 40 ifs with
_x++;_x--;_rotation=random(360)
and they took less than 1 millisecond to do. but every once and a while the one with Key.isDown(65) in each if would say 1 millisecond instead of 0 and they were tested simultaneously so bleh.

are you sure about that? out of 158 tests, my way took shorter timer to process 58 times, the regular way was shorter 7 times. most of the time they both took 0 milliseconds saince i guess i didnt try anything too computer intesive.

At 1/22/06 01:28 PM, Sekky wrote: wait, are you using multiple if (meh) {} if (meh) {} statements in the same code?

this is the code im using to check

onClipEvent (load) {
var ties:Number = 0;
var wins:Number = 0;
var loss:Number = 0;
var said:Boolean = false;
}
onClipEvent (enterFrame) {
var t:Number = getTimer();
//time it started my ways test
var a:Boolean = Key.isDown(65);
for (var i = 0; i < 5000; i++) {
if (a) {
_x++;
_x--;
_rotation = random(360);
}
}
if (a) {
var myTime:Number = getTimer() - t;
//time it took for my ways test
}
t = getTimer();
//time it started other ways test
for (i = 0; i < 5000; i++) {
if (Key.isDown(65)) {
_x++;
_x--;
_rotation = random(360);
}
}
if (Key.isDown(65)) {
var otherTime:Number = getTimer() - t;
//time it took for other ways test, all code afterwards is not counted in that number so it should be 100% accurate.
myTime < otherTime ? wins++ : myTime > otherTime ? loss++ : ties++;
//tallys up score
said = false;
//allows it to trace score
} else if (!a && (wins || losses || ties) && !said) {
trace([wins, loss, ties]);
said = true;
//so it only traces once
}
_rotation = 0;
}

i changed the for loop from 50 to 5000 to get a more accurate answer.

Sweet tut Toast. I've been wondering how to use letter and number keys. Reminds me of graphing calc programming.

[mcarr1973]

with the:
if(Key.isDown(65)){
trace("yay");
}
How would I ad code to the above to go to a certain frame label and play what on that timeline. for example I have a boxer on the main timeline (a MC) and inside that movie clip is another movie clip called fighter(instance name) which is key framed out with frame labels like punch (label) kick(label).

I'm having trouble writing the above code to make my boxer punch when the A(65) key is hit. can you help me with this code?

P.S. where do I put the code? (in a frame on the main timeline or in the boxer MC or in the fighter Movie Clip?)

If you can help I thank you soooo very much! im pulling my hair out. lol

You could just:
if( Key.isDown("A".charCodeAt(0)) ) {
//

I'm having a hard time understanding this.. I'm a real noob when it comes to actionscripting. What I want is a code that will take me to a certain frame (or scene) when a button is pressed at the right time (kinda like the Naked Hero games).

So, from what I've gathered, I'd have to use:

if(Key.isDown(65)){
gotoAndPlay("Scene 1", 1);
}

That would take the flash to scene 1, frame 1 when the viewer presses the "a" key, right?

Well I tried and nothing happened! I didn't get any error report, just nothing happened when I tested it.. What am I doing wrong?

[Ivaron]

(sorry for double post)

do I need to put it in a movie clip or in a keyframe?? Maybe that's what I'm doing wrong....

Um, none of this seems to be working for me,
i put:

if(Key.isDown(65)){
play();
}

on the first keyframe where the stop(); action is...
I load the movie I hit A and it doesnt play the movie. What am i doing wrong?
(i know i am such a newb)

[Toast]

onClipEvent(enterFrame){
if(Key.isDown(65)){
play();
}
}

Paste that in the action panel of your movie clip.
