Save Players x And y Coordinates

[Alpharius120]

This is an AS3 question.
Alright, so in this game I'm currently developing (which is basically 4 guys and a wall right now) you press P to go into the pause menu. Easy enough. And to leave the pause menu you press the Resume button. Obviously. My problem is with when I go into the pause menu, after moving a bit away from my start position, and resume, it resets my characters x and y coordinates. I need some way to save his x and y coordinates when I go into the pause menu and load them when I leave. I don't know what code to put down so I'll just put down the Resume code and the Pause code.

Pause:

function checkKeys(event:KeyboardEvent):void {
        if (event.keyCode == 80) {
		gotoAndStop("PauseMenu");
	}
}

Resume:

function onIntroClick(evt:MouseEvent):void {
	gotoAndStop(1);
}

Sorry I can't post any code right now to solve your problem but when you run the pause function also try removing any other event listeners or disabling any buttons that may change the player's x and y coordinates (maybe that will stop the player's positions from changing while paused.)

Another idea is when the game is paused, add the player's x and y coordinates to variables, and when the game is un-paused make the player's x and y positions equal to that of the variables.

Hmm... while saving the coordinates to variables, should work, I must question your technique of pausing the game. Would it not be easier to just make a pause menu movieclip, and, while paused, have it be visible, and while not paused, make it not be visible? Seems much more simple, for lack of a better word, to do it this way.

Oh yeah, that's a great idea. That way I'll never have to save x, y coordinates, they'll be there all along. Thanks a lot! Time to test this out.

I agree with Schmastalukas. You could alternatively attach the menu movieclip (rather than change whether it is visible).

For the original question, though, all you'd have to do is save the values in a variable:

mySavedX = character._x;
mySavedY = character._y;

And on resume, place the character back.

character._x = mySavedX;
character._y = mySavedY;

You might not need that now, but you will probably need the concept for other things later on in game development.

^ BTW that's AS2. I'm not sure if AS3 variable setting and such has different syntax rules or not.

I actually did try this and we figured it should have worked but it didn't for some odd reason. Next time i need this I'll try it with the underscore, because we didn't have that before.

Alright sorry for the double post but I have a question about the visible thing. I put this code in assuming it would work, but it slowed down the script a lot and actually timed out.

menu.visible = false;
function checkKeys(event:KeyboardEvent):void {
        if (event.keyCode == 80) {
		menu.visible = true;
	}
	if (event.keyCode == 80) {
		while (menu.visible = true);
		menu.visible = false;
	}
}

Again, I use AS2 so I may be ignorant about some of the changes... but the while function is a loop, and you only want to call the code one time (while looping is used to execute a block of code several times). Change that to "if" and see what you get.

[ShirkDeio]

Plus, you are setting it to true then telling it to change it to false. Here's what it should be according to my AS2 knowledge:

if (event.keyCode == 80 && !menu.visible) {
     menu.visible = true;
} else {
     menu.visible = false;
}

while (menu.visible = true);

}
}

You could just say menu.visible = !menu.visible, and only have one if statement. Or, if that doesn't work, and i'm not sure if it will in AS3, you could do something like...

if (event.keyCode == 80) {
     if (menu.visible) {
          menu.visible = false;
     } else {
          menu.visible = true;
     }
}

Well, I'm using AS3, but this is what it should look like I believe I'm going to test it out.
And it works, thanks a whole lot!
That should be the extent of my problems with this, thanks for your help guys.

Alright, one more problem actually. When the menu becomes visible I can't press the buttons to perform the actions such as going to the Items menu, the Stats menu, and the Save menu, but it will resume.
Here's my code.

function onIntroClick(evt:MouseEvent):void {
	menu.visible = false;
}

function onOutroClick(evt:MouseEvent):void {
	ItemMenu.visible = true;
}

function onClick(evt:MouseEvent):void {
	StatMenu.visible = true;
}

function onClack(evt:MouseEvent):void {
	SaveMenu.visible = true;
}

menu.addEventListener(MouseEvent.CLICK, onIntroClick);
ItemMenu.addEventListener(MouseEvent.CLICK, onOutroClick);
StatMenu.addEventListener(MouseEvent.CLICK, onClick);
SaveMenu.addEventListener(MouseEvent.CLICK, onClack);

Instead of making your pause menu movie clip become visible and invisible, just use addChild(); and removeChild(); instead - this way the menu won't be on the stage while the game is un-paused, and therefore won't be slowing down the game as much.

The buttons may not be working because they might be underneath the pause menu movie clip. You should just put menu items inside the menu movie clip.

I didn't even think of using addChild();. Now it works perfectly, thanks for all your help everyone.

Just one more thing I'd like to add. It probably didn't work because you have to put the code with the variables on a different layer, so it doesn't refresh when you un-pause the game and go back to the original frame.
