[Flashcoders] Prevent space button passing click event to button (as3)
I have created a game in AS3 that uses the SPACE bar on the keyboard to make the character jump. I have encountered a problem whereby pressing the SPACE bar causes a button on my game screen to be clicked. I read up that setting buttonMode to false would fix this but it does not seem to like me using this property on my button. i.e I tried gameMenuBtn.buttonMode = false; but here is the error message: 1119: Access of possibly undefined property buttonMode through a reference with static type flash.display:SimpleButton. My button is a custom button I have created and not a button from the components library i.e I just selected a graphic and converted to a symbol and choose Button. Any ideas how to prevent this button being clicked by the SPACE bar being pressed? I could change the key for jumping but feel that the SPACE bar is the standard one used for this.

My guess is that the button has the focus at that particular moment. So maybe you can set button.mouseEnabled = false; And set a listener to enable the button on pe. if mouseX and mouseY is at a specific point.

Re: [Flashcoders] Prevent space button passing click event to button (as3)
Buttons are meant to be pressed like that. You are using the wrong object for the job. Here is my take on it: you have a game where there are button instances in the gui. I would add the keyboard listener to the stage as usual. However, in the listener, I would add a condition to ignore events for things that actually have a logical response. if(e.target is TextField||e.target is SimpleButton||(e.target is Sprite Sprite(e.target).buttonMode)) return; ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

Thanks for the replies.
When you say buttons are meant to be pressed like that - do you mean that
it is standard practice to use the tab key to move between buttons and then
use the SPACE key to click it?
You are correct in assuming I have a game where there is a button on the
interface that allows the user to quit the game.
I have the following code on this button:
gameMenuBtn.addEventListener(MouseEvent.CLICK, clickGameMenuButton);
function clickGameMenuButton(event:MouseEvent) {
gotoAndStop(splash);
}
I was hoping there was just a simple way to prevent the SPACE key from
virtually clicking this button. I still want the user to be able to click it
with the mouse.

Thanks Henrik - yes totally agree that it is a great accessibility feature - I guess it just tripped me up as this wasn't the case in AS2 as far as I am aware - think it was the enter button previously? -Original Message- From: flashcoders-boun...@chattyfig.figleaf.com [mailto:flashcoders-boun...@chattyfig.figleaf.com] On Behalf Of Henrik Andersson Sent: 02 December 2009 13:36 To: Flash Coders List Subject: Re: [Flashcoders] Prevent space button passing click event to button (as3) Paul Steven wrote: Thanks for the replies.
