[AS3] Using Score In Game

[glovaxlr]

Hey, new to the boards here. I am currently in a flash gaming class, and I am making a game, obviously. Anyways what I'm trying to accomplish is when the score goes to zero I want the game to end and go to the gameover screen.

this is the specific section of code that I have been experimenting with.

if (ScoreField.text == "Life: 0")
{
gotoAndPlay("fail");
}


This code has currently done nothing. And any variation I've created has only created errors. Any suggestions on how to do this correctly will be greatly appreciated. Thanks!

Erm... so what is your question?

It's hard to find the problem without actually knowing what is what. For all we know, scorefield has nothing to do with anything. You could have been using the wrong textfield, etc. It'd be better to upload the .fla or at least give us way more detail.

this is all the actionscript of the file
textfield is the name of a dynamic text box that the score is shown in. it begins at 100, when it gets to 0, i want the game to be over




var score = 100;

import flash.ui.Mouse;
Mouse.hide();
function init()
{
Mouse.hide();

//respond to mouse move events
stage.addEventListener(MouseEvent.MOUSE_MOVE, mouseMoveHandler);
}

function mouseMoveHandler(evt:MouseEvent):void
{
//whenever the mouse moves, place the cursor in the same spot
circle.x = evt.stageX;
circle.y = evt.stageY;
}



var myText:TextField = new TextField();
myText.text = "You got this, c'mon let's keep it up!";


addEventListener(Event.ENTER_FRAME, checkCollision);

function checkCollision(event:Event){

//check the cursor location against the rectangle
if(rectangle.hitTestPoint(mouseX, mouseY, true)){
messageText1.text ="";
{
ScoreField.text = "Score: "+(score=50);

}

}else{
messageText1.text = "";
ScoreField.text = "Life: "+(score-=1);
}

//move circle with mouse
circle.x = mouseX;
circle.y = mouseY;

//test circle versus rectangle
/*if(circle.hitTestObject(rectangle)){
messageText2.text = "hitTestObject: YES";

addChild(myText);



}else{

addChild(myText);

removeChild(myText);
messageText2.text = "hitTestObject: NO";


}*/
}

//fail game, score goes negative and sent to fail screen

if (ScoreField.text == "Life: 0")
{
gotoAndPlay("fail");
}

Since the variable score holds the score too, use that.
if (score==0) {
gotoAndPlay("fail");
}

You can use [.as] yourcodehere[/.as] to make your code highlighted. Remove the dots.

I replaced


if (ScoreField.text == "Life: 0")
{
gotoAndPlay("fail");
}

with


if (score==0)
{
gotoAndPlay("fail");
}

but still, nothing has changed. When the score hits zero it just keeps going down into negative numbers, rather than playing the frame under label "fail" which is the game over screen.

(thanks for the wrap tip, the as looks better like that :)

Do you mind uploading your .fla so I can have a look at it? If you are looking for a place to host it, http://www.willhostforfood.com can host it for free.

Fixed it for you. It's because your code wasn't in an enter_frame event listener. The code only ran once when it started- and it definitely wasn't 0 then. The enter_frame runs every frame, so it always checks to make sure it's 0. When you complete the game, you'll get output errors since the function checkCollision() hasn't been removed. Use removeEventListener to do that (check my example, it's on the top).

EDIT: Remember to remove your current if statement for checking 0 at the end of the code.

oh wow, awesome, you rock! thank you I appreciate it, for fixing, and for the quick lesson

[finaiized]

No problem. PM me if you need further help on the checkCollision error.

Wow. that game is difficult.

Wow. that game is difficult.

Hint: Open the .fla and go to the enemy's timeline. It's a motion path- he takes the same path every time! xD
