[RESOLVED] [F8] Making a Character "Teleport"

[Pakorn1]

Hey all,

I'm having trouble getting this character in my side-scrolling platform game to teleport. Basically there are going to be a lot of walls and when you walk into one, you see an effect and then the camera and the character should pan over to another room.

I am trying to accomplish this using tweens. The following code is my function; can anyone tell me what I'm doing wrong? It traces correctly (though the hit seems to be a little weird.)

if (g.wall1_1.hitTest(this._x-20, this._y, true)){
trace("PORT");
var c = _root.char;
var home = _root;
c.gotoAndPlay("port");
var teleportX:Tween = new Tween( c, "_xPos", regular.easeInOut, c._x, -90, 1, true );
var teleportY:Tween = new Tween( c, "_yPos", regular.easeInOut, c._y, 250, 1, true );
var rootTeleportX:Tween = new Tween( home, "_xPos", regular.easeInOut, home._x, -90, 1, true );
var rootTeleportY:Tween = new Tween( home, "_yPos", regular.easeInOut, home._y, 250, 1, true );
}

Well I personally wouldnt use tweens at all. simply use a math interpolations to move the camera around. like this:

	function ease(a, b, easeSpeed) {
		var c:Number;
		c = b-a;
		if (c == 0) {
			return 0;
		}
		return c/easeSpeed;
	}

the way to use it is like this:

//x=ease(x, destX, 5);

//Correction!

//OOPS!
//sorry this is the correct code to use

x += ease(x, tx, 5);

That code is what I use to move my characters around in my game, Ease returns a value between a and b and that value gets smaller each time you call it.

I'm not sure if that will work for me;

I need the character to disappear and then reappear at the new spot. I was planning to use the "onMotionStopped" property for this. Is there something similar using your code?

AzraelKans

when c = 0 u shoud return b not 0 otherwise the x position well suddenly jump

pakorn if ur planning to make him disappear than just turn visibility off when he hits the wall position him at his new spot (if u want the camera to move to that spot use azraelkans method) than when the camra's there just turn visiblity back on

I don't think I'm using this correctly...I keep getting errors and it doesn't seem to be doing it properly.

Can I see an example using plugged in variables and numbers? I don't know where I should be using "A, B or C" and where I should be using an actual number.

[slicer4ever]

a is the current position of your mc(x or y), b is where you want your mc to go, and c is the speed at which you want it to travel their what is returned is the new position of your object

give me 5 min and i'll write a small script using that method

ok here: .fla/.swf

i had to use a diffrent method since AzraelKans was producing a weird result anyways this is a substitute
only shows for the x-axis movement you would just repeat for y

"weird.rar: The archive is either in unknown format or damaged"

I have Winrar... this file won't extract though. It gives this error message plus a popup that says no archives found...

[slicer4ever]

i dl'ed it and extracted it fine, it should be about 7kb

edit: try this link
.fla

So it still doesn't seem to be working. He just kind of teleports back to where he just hit the wall, so he's just kind of right there, "glitching out."

Maybe I oughta post the code as I am using it, see if something is wonky...

if (g.wall1_1.hitTest(this._x-20, this._y, true)){
        trace("PORT");
    c.speed = 0;
    var c = _root.char;
    var home = _root;
    c.gotoAndPlay("port");
    move_to_object = function(a, b, speed){
        if(b>a){
            speed*=1;
        }else{
            speed*=-1;
            }
        if(a>b-(speed*2) && a<b+(speed*2)){
            return a;
            }
        a+=speed;
        return a;
        }
    main = function(){
        _root._x = move_to_object(_root._x, g.dest1_1._x, 10);
        }
    main();
} 

I think it's because this code is executed on a hitTest, and so as soon as the MC moves off the hit area the code stops running. . . how can I make it loop so that it runs until he hits the destination area?

I tried a while loop but it freezes the .swf

your theory is absolutely correct here is how to do it so that he well continue:

(o and i'm ganna clean up the code a tad bit)

var move_to_dest = false;

move_to_object = function(a, b, speed){
     if(b>a){
          speed*=1;
     }else{
          speed*=-1;
     }
     if(a>b-(speed*2) && a<b+(speed*2)){
          return a;
          //since move_to_dest was declared outside this method we can call to it inside the method
          move_to_dest = false;
     }
     a+=speed;
     return a;
}


if (g.wall1_1.hitTest(this._x-20, this._y, true)){
     trace("PORT");
     c.speed = 0;
     var c = _root.char;
     var home = _root;
     c.gotoAndPlay("port");
     //this basically allows us to tell the program hey we wanna move to the destination
     move_to_dest = true;
} 

//this moves us to that destination=-)
if(move_to_dest==true){
     _root._x = move_to_object(_root._x, g.dest1_1._x, 10);
}

u never want to call a while loop inside a mc the only time i ever do is on the frame code any other time it just screws the program over instead since flash alwaysloops to each movie clip(and you can see this above) try doing the loop using varibles and if statements to tell the program how to react to get from a-b and maybe even c

[Pakorn1]

OK, I think I got it working! I had to change the var move_to_dest in its initial declaration, so instead of saying var move_to_dest = false; I had to just declare the variable (otherwise it was still stopping movement when the guy moved out of the hit area.)

Now, though, I have to figure out how to declare him stopping...
