Off screen movement

Um · 11-14-2005 12:26 PM

I have made small game, but my animation is going out of the dcreen when I move it. Can somebody please give me the code how can I stop the animation when it riches the end of the screen.

This is the code that I have in my game:

Code:

function moveHeli&#40;speed&#41; &#123;
	if &#40;Key.isDown&#40;Key.UP&#41;&#41; &#123;
		_root.longbow._y -= speed;
	&#125; else if &#40;Key.isDown&#40;Key.LEFT&#41;&#41; &#123;
		_root.longbow._x -= speed;
	&#125; else if &#40;Key.isDown&#40;Key.DOWN&#41;&#41; &#123;
		_root.longbow._y += speed;
	&#125; else if &#40;Key.isDown&#40;Key.RIGHT&#41;&#41; &#123;
		_root.longbow._x += speed;
&#125;
&#125;
_root.onEnterFrame = function&#40;&#41; &#123;
	moveHeli&#40;5&#41;;

then I have try with this, but I don't know how to finish...:

Code:

stage_x = 550;
stage_y = 650;
hero_x = getProperty&#40;"longbow", _width&#41;;
hero_y = getProperty&#40;"longbow", _height&#41;;
function moveHeli&#40;speed&#41; &#123;
	if &#40;Key.isDown&#40;Key.UP&#41;&#41; &#123;
		_root.longbow._y -= speed;
	&#125; else if &#40;Key.isDown&#40;Key.LEFT&#41;&#41; &#123;
		_root.longbow._x -= speed;
	&#125; else if &#40;Key.isDown&#40;Key.DOWN&#41;&#41; &#123;
		_root.longbow._y += speed;
	&#125; else if &#40;Key.isDown&#40;Key.RIGHT&#41;&#41; &#123;
		_root.longbow._x += speed;
&#125;
&#125;
_root.onEnterFrame = function&#40;&#41; &#123;
	moveHeli&#40;5&#41;;

Hi,

Simple boundary check function. Paste the function onto the first frame of your movie and pass it the instance name of the targetMC you want the boundary set for........

Code:

function checkBoundary&#40;myTarget&#41; &#123;
	this.onEnterFrame = function&#40;&#41; &#123;
		if &#40;myTarget._x>Stage.width&#41; &#123;
			myTarget._x = 0;
		&#125; else if &#40;myTarget._x<0&#41; &#123;
			myTarget._x = Stage.width;
		&#125; else if &#40;myTarget._y>Stage.height&#41; &#123;
			myTarget._y = 0;
		&#125; else if &#40;myTarget._y<0&#41; &#123;
			myTarget._y = Stage.height;
		&#125;
	&#125;
&#125;
//Usage
checkBoundary&#40;_root.mcInstanceName&#41;;

			myTarget._y = Stage.height;
		&#125;
	&#125;
&#125;
//Usage
checkBoundary&#40;_root.mcInstanceName&#41;;

I didn't do something good here.

I have animation with name longbow (that animation can't go out of the screen) label name is longbow. This is the code that I have insert but it doesn'd do, what did I do wrong?

Code:

stop&#40;&#41;;
function checkBoundary&#40;longbow&#41; &#123; 
   this.onEnterFrame = function&#40;&#41; &#123; 
      if &#40;longbow._x>Stage.width&#41; &#123; 
         longbow._x = 0; 
      &#125; else if &#40;longbow._x<0&#41; &#123; 
         longbow._x = Stage.width; 
      &#125; else if &#40;longbow._y>Stage.height&#41; &#123; 
         longbow._y = 0; 
      &#125; else if &#40;longbow._y<0&#41; &#123; 
         longbow._y = Stage.height; 
      &#125; 
   &#125; 
&#125; 
//Usage 
checkBoundary&#40;_root.longbow&#41;;

Hi,

You dont need to change anything in the function. I coded it so it is very easy to use

All you need to do is pass the instance name of the target clip that you want to set the boundary for to the function.......

Code:

function checkBoundary&#40;myTarget&#41; &#123; 
   this.onEnterFrame = function&#40;&#41; &#123; 
      if &#40;myTarget._x>Stage.width&#41; &#123; 
         myTarget._x = 0; 
      &#125; else if &#40;myTarget._x<0&#41; &#123; 
         myTarget._x = Stage.width; 
      &#125; else if &#40;myTarget._y>Stage.height&#41; &#123; 
         myTarget._y = 0; 
      &#125; else if &#40;myTarget._y<0&#41; &#123; 
         myTarget._y = Stage.height; 
      &#125; 
   &#125; 
&#125; 
//Usage 
checkBoundary&#40;_root.longbow&#41;;

OK, now I understand. But I have inserted and still nothing. My mc (animation) is in layer one and the actions script is in frame two. In this action scritp there is function for moving longbow and function that you have gave me.

Like this:

Code:

stop&#40;&#41;;
function checkBoundary&#40;myTarget&#41; &#123; 
   this.onEnterFrame = function&#40;&#41; &#123; 
      if &#40;myTarget._x>Stage.width&#41; &#123; 
         myTarget._x = 0; 
      &#125; else if &#40;myTarget._x<0&#41; &#123; 
         myTarget._x = Stage.width; 
      &#125; else if &#40;myTarget._y>Stage.height&#41; &#123; 
         myTarget._y = 0; 
      &#125; else if &#40;myTarget._y<0&#41; &#123; 
         myTarget._y = Stage.height; 
      &#125; 
   &#125; 
&#125; 
//Usage 
checkBoundary&#40;_root.longbow&#41;;

function moveHeli&#40;speed&#41; &#123;
	
	if &#40;Key.isDown&#40;Key.UP&#41;&#41; &#123;
		_root.longbow._y -= speed;
	&#125; else if &#40;Key.isDown&#40;Key.LEFT&#41;&#41; &#123;
		_root.longbow._x -= speed;
	&#125; else if &#40;Key.isDown&#40;Key.DOWN&#41;&#41; &#123;
		_root.longbow._y += speed;
	&#125; else if &#40;Key.isDown&#40;Key.RIGHT&#41;&#41; &#123;
		_root.longbow._x += speed;
	&#125;	
&#125;
_root.onEnterFrame = function&#40;&#41; &#123;
	moveHeli&#40;5&#41;;
&#125;;

Nothing. When I insert your code after "moving" function, I can't move my longbow...

Look, NTD, I am sorry to giving you such a deal and work for nothing, but I am new in this and I would really like to learn flash. People like you (with such expiriance) are my only help...

Hi,

My mc (animation) is in layer one and the actions script is in frame two.

Actions should reside on the first frame of your movie. It is generally standard practice to create a layer above all other content and paste actionscript to it's own individual layer. The span on the timeline for the actionscript should span the length of any layers underneath.

Sorry, I didn't say well. Bouth of them are in frame 116, but animation (longbow) is in layer 2 (up) and script is in layer 1 (down). Before 116 frame there is preloader, then short intro and menu with play, instructions and exit.
So when your press play button the game start on 116 frame.
Hope that this is Ok, my longbow animation moves and everything is OK, but the script for "not-going-off-the-screen" (script is like I posted before) doesn't do anything.

I try to insert it on frame 2, but then longbow animation wonts move at all.
I think that "move-code" and "not-going-off-the-screen" action scripts must be on 116 frame, but only problem is why doesnt your code function there...
Hm, some times I feel like idiot, I am very ashamed now, you must be thinking:"Oh, comeon, if you cant do this, leave it..", but every start is difficult.

You help me and maybe I can help you in something other if you are interested in... For example, how to make themes and skins for SonyEricsson P800/P900/P910i or any other SonyEricsson model...

This is the code that I have insert now. And it works, but works really strange.
When my heli (longbow) is totaly out of the screen he comes back from other side, I wont that my heli stops right when he reach to the end of the stage.

Code:

stop&#40;&#41;;
function moveHeli&#40;speed&#41; &#123;
	
	if &#40;Key.isDown&#40;Key.UP&#41;&#41; &#123;
		_root.longbow._y -= speed;
	&#125; else if &#40;Key.isDown&#40;Key.LEFT&#41;&#41; &#123;
		_root.longbow._x -= speed;
	&#125; else if &#40;Key.isDown&#40;Key.DOWN&#41;&#41; &#123;
		_root.longbow._y += speed;
	&#125; else if &#40;Key.isDown&#40;Key.RIGHT&#41;&#41; &#123;
		_root.longbow._x += speed;
	  &#125; else if &#40;longbow._x>Stage.width&#41; &#123; 
         longbow._x = 0; 
      &#125; else if &#40;longbow._x<0&#41; &#123; 
         longbow._x = Stage.width; 
      &#125; else if &#40;longbow._y>Stage.height&#41; &#123; 
         longbow._y = 0; 
      &#125; else if &#40;longbow._y<0&#41; &#123; 
         longbow._y = Stage.height; 
      &#125; 
   &#125; 
_root.onEnterFrame = function&#40;&#41; &#123;
	moveHeli&#40;5&#41;;
&#125;;

Also, when I insert the game on the web, my heli (longbow) doesn't move at all, but on my comp it move...

Here is the game that I have insert to try how it works on web, you'll see that heli doesn't move...

Hi,

The motion works, you just need to make sure the page is in focus. Click on the screen and the motion works. Try adding the full path to the movieclip in the boundary check. The same as you have it for the motion.....

_root.longbow..........instead of just longbow
