keypress = enable (show) GUI

[td]

Can't find the answer...
Just try set up the key (Space) button => enable (show) GUI. But i cant.

I paste code in Global script:

if (IsKeyPressed(32) == 1)
gui(3). Visible = true ;

What i do wrong

[Ubel]

It should be done like this:

Code: ags

if (IsKeyPressed(32) == 1) {
Ã,  gui[3].Visible = true;
}

I changed the () marks to []

[Ashen]

Also, where exactly in the Global Script is it?
IsKeyPressed I think needs to be use in repeatedly_execute to work properly. You could also add to on_key_press, e.g.:

Code: ags

function on_key_press(int keycode) {
  // called when a key is pressed. keycode holds the key's ASCII code
  if (IsGamePaused() == 1) keycode=0;  // game paused, so don't react to keypresses
  if (keycode == 32) gui[3].Visible = true;
  // Other keycode conditions (Quit, Save, Load, Inventory, etc)
}

But i can do this in global script :
if (keycode==8)  gui[3].Visible = true;

Function is work...and now gui3 must disappear when "space" pressed again. Global script to allow do this?

[Gilbert]

if (keycode==8)  if (gui[3].Visible) gui[3].Visible = false;
else gui[3].Visible = true;

Though this way the gui might flash on and off if you keep the key pressed, I'm too lazy to work something about this though.

EDIT: TD's problem's solved.

[td]

Yay! Now it's work! Thanks to dudes and cyborg!

[td]

Wait the minute!!! Some mistake there. I suppose ur was right
alkis21!!!

[Ubel]

Code: ags

if (keycode==8) {
Ã,  if (gui[3].Visible==true) {
Ã,  Ã,  gui[3].Visible=false;
Ã,  Ã,  return; } //"return" stops running any more functions
Ã,  else {
Ã,  Ã,  gui[3].Visible=true;
    return; }
}

This should work.

Does Pablo's suggestion work, TD?

[td]

Wah! Dosn't work...
GUI apeear when push the button but not disappear when push the button again...

...well, guess so better to set other button for disappearing GUi...

[Ashen]

Pablo's code should work... Can you post your on_key_press code?
What key do you want to turn the GUI on/off? You originally said Space, but now you're using keycode 8, which is Backspace.

[Khris]

If the GUI is set to Pop up modal, on_key_press won't get called while it is open, AFAIK.

[Ashen]

Ah, that's true. In that case, you will need to use IsKeyPressed like you originally had, and check it in repeatedly_execute_always, as this runs when Popup Modal GUIs are visible. You might also want to use a variable to stop it 'blinking' on and off if the key is held (what Gilbot said), e.g. (untested):

Code: ags

int KeyHeld;

function repeatedly_execute_always () {
// Make rep_ex_always if there isn't one, or paste this in if there is:
  if (IsKeyPressed (8)) {
    if (KeyHeld == 0) {
      if (gui[3].Visible==true) {
        gui[3].Visible=false;
      }
      else {
        gui[3].Visible=true;
      }
      KeyHeld = 1;
    }
  }
  else KeyHeld = 0; // Reset it when key released.
}

EDIT:
Corrected conditions. This version DOES work, honest, but Pablo's module (or at least hthe way he's modified on_key_press) might be better.

[alkis21]

Ashen, I don't think your code would stop the blinking either.
EDIT: I just tested it and it doesn't.

Here's how I did it (I have a GUI that pops up when Space is pressed too):

Code: ags

int KeyHeld=0;
function repeatedly_execute_always() {
  if ((KeyHeld) && IsKeyPressed(KeyHeld)) return;
  KeyHeld=0;
  if (IsKeyPressed(' ')) {
    gui[3].Visible = (!gui[3].Visible);
    KeyHeld = ' ';
    }
}

[Ubel]

I would make a new module and put a on_key_press() function inside it, without the line that blocks keypresses while the game is paused. In my opinion this would be the most non-confusing way of doing this. Actually I just made one. Just import this module into AGS from the Module Manager.

There.

Seems it work, Pablo! (SOLVED)
