onKeyPressed()

PHP Code:


		
			
function onKeyPressed(code,key)

{

  if (key == ???)

You could get them with something like this:

PHP Code:


		
			
function onKeyPressed(code, key) {
  player.chat = code;
}

you could also use....

PHP Code:


		
			
function onKeyPressed(keycode, key, scancode) {
  player.chat = keycode SPC "/" SPC "/" SPC scancode;
}

to check all params'

PHP Code:


		
			
function onKeyPressed() {
  if (keydown(0-3)) {
    player.chat = "arrow key pressed";
  }
}

keydown(int) can be used along with onKeyPressed() to detect default key configurations.

Why would he need the code if he can detect it with the alternative I gave? Not to mention he was already given a script to detect the code... so yeah.

That's a bit vague for someone that might not be familiar with loops since they wouldn't realize that they would benefit from using one in this case:

PHP Code:


		
			
function onKeyPressed() {

  for (temp.key = 0; temp.key < 4; temp.key++) {

    if (keydown(key)) {

      player.chat = "directional key pressed";

    }

  }

}

Stuff like this has been posted before, possibly in multiple threads, people should really use the search function, they would get answers to their questions much faster.

EDIT: It's probably better to say 'directional key pressed' instead of 'arrow key pressed' since that would imply that the script would only trigger when you press an arrow key, when in fact it would trigger whenever you pressed any of the directional keys that you have set in your F3 options.

Eh, I was more providing the values he could use(0-3) rather than implying he should loop... which he should.

As for arrows vs directional... probably, but it should always be applied to the customization of the player. If the player chooses to use WASD as their directional keys, this should also apply to whatever GUI's the player is using, so really directional translates into arrow as the player customizes them to basically be such(even if they're regular keys instead of the arrow keys). Developers need to keep that in mind.

It would be better if Stefan would provide a variable for which keys are used for movement/other stuff.

It's silly and redundant to have an event that passes paramaters, only to then have to call another function to see if a key is pressed, but I guess that's Graal.

I only read "Pelikano" on the left side of my screen, then realized the following text wouldn't be worth paying attention to.

What're you trying to do? If you're wanting for it to operate with Graals origional keys (those that you can change using the 'F3/Change Keys' option) you'll need to use keydown(variable).

Here's a couple of examples to show this

HTML Code:

function onKeyPressed() {

  temp.dirs = {"Up", "Left", "Down", "Right"};

  for (temp.dir = 0; temp.dir < 4; temp.dir++) {

    if (keydown(temp.dir)) {

      player.chat = "Pressed" @ temp.dirs[temp.dir];

    }

  }

}

HTML Code:

function onKeyPressed() {

  if (keydown(0)) player.chat = "Moving up";

  elseif (keydown(1)) player.chat = "Moving left";

  elseif (keydown(2)) player.chat = "Moving down";

  elseif (keydown(3)) player.chat = "Moving right";

}

Here are the keydown variables:
0, 1, 2 & 3 are all movement keys
4 is 'A'
5 is 'S'
6 is 'D'
7 is the map key [default- 'M']
8 is the tab key (chat toggle)
9 is the inventory [default- 'Q']
10 is for pausing [default- 'P']

Hope this helps.
