ActionScript 2.0 :: MovieClip Movement / Rotation And Position
Apr 24, 2005
I'm having a problem with a little movement script I wrote for a MC I have. I believe it either has to do with variable scoping, or with a coordinate system problem. (If I change the xPos and yPos in the onClipEvent (load) to 0,0...then the MC starts in the middle of the field (MC) I'm trying to move it inside of.) Basically...the ActionScript you see below is a part of the "Player" MC...who is supposed to move around a "field" MC I have.
(I was assuming setting xPos and yPos to 0 would have the Player MC starting at the very top left of the entire screen...which instead it starts in the middle of the "field" MC.) Also - When I press the different arrow keys...the Player MC jumps around to different locations...but once at the new location the movement (in a single direction) works okay. I've attached the .swf.

Essentially what I'm trying to do is nearly the same as this: http:[url].......However I'd like to ease/tween the movieclip position and rotation to the mouse position.The main issue I see is trying to get the current movieclip rotation and the target rotation,then tween it cockwise or counterclockwise from current to target.The way a movieclips rotation uses positive and negative numbers throws it off.If you just want to lock the mc rotation to the mouse rotation its fine, but once you try to tween it you run into difficulties. So the end effect would be like if you were to draw imaginary clockwise circles around the object, it should just keep rotating clockwise towards the mouse. Then if you started going counter clockwise it should just keep easing counter clockwise to the mouse.

I have 2 container MovieClips (mc1, mc2), each of them has a separate x,y, rotation. I want to take a child from mc1 and addChild() it to mc2 while keeping the same x, y, and rotation on the screen so you see the added child mc as if it didnt change position or rotation, just moved to the other MC.
Trying to use an enterFrame event in conjunction with two functions that combined I want to move my object (a square) from the right to the left side of the screen and rotate it AROUND THE CENTER.When I use the following functions individually, they both work fine:
Actionscript Code: //Centering function function rotCenter (ob:*, angleDegrees:Number, ptRotationPoint:Point) { var m:Matrix=ob.transform.matrix; m.tx -=
I have a rock movieclip that is in an array and a timed function that places an instance of the rock on the stage every 5 seconds. So every 5 seconds a rock is placed onto the stage. What I want is when a rock is placed onto the stage it rotates either clockwise or anticlockwise. So every 5 seconds a rock appears and it will rotate either clockwise or anitclockwise. I also want the rocks to rotate at a random speed. So every time a rock appears its rotation speed will be different. I also need the rocks to move in a random direction. So every time a rock appears it will travel in a different direction to the previous rock.
I have child (1) and I am rotating it by some custom num of degrees. After rotation (2) I want to 'align' this child to left_center side of the parent (should look like 3). Without roration I would set x to 0, but after rotation position of registation point changes.
way to calculate new x/y position based on rotation.
I have a circle wheel i want to rotate and the speed should be based on the mouse position. I also need to have easing in and out.
When the user hovers over the bottom of the circle it will begin to rotate one way and then th top of the circle would make it rotate the other way. The further to the top or bottom they are the quick it spins. It ideally needs to ease in and out when it starts and stops when the user moves the mouse away.
The circle will be the complete movie so 50% top and bottom each for each direction.
I'm trying to make a movieclip rotate around it's center (this is no problem since the center will never change). The problem that I am having is when I press the movieclip, in let's say the bottomright corner, and move the mouse the movieclip flips to a certain angle depending on my mouseposition. After the weird flip it works fine but it's the initial mouse click that makes the movieclip flip to an angle.I've tried playing around with different values to substract or add the starting angle but eveytime the result is not what i am looking for.Current code:
I have created a globe that rotates with no problem, but what I am trying to do is to control the direction of the rotation based on the mouse position. For example, if the mouse is to the right of the globe, it rotates towards the right and if the mouse in on the left, the globe rotates left. When the mouse is over the globe, it should stop.
I wanted to built an enemy that is able to move on stage randomly in xposition and perhaps able to detect my character within the detectable zone and chase after me.. but currently I just wanted to make the enemy move randomly in x-position for starter.
It is my first time making and enemy with AI, but I'm just wasn't sure where to begin, I have used a fairy easy script to animated the movieclip in the beginning but got stucks whenever it reaches 960 or below 0 of the stage
addEventListener(Event.ENTER_FRAME,initGames); function initGames(e:Event):void{ moveEnemy(); }
I want the diameter of the 'balls' orbit to change dependant on the position of the mouse but keep the point of rotation exactly the middle of the stage at all times.I.e. if the mouse is hovering over the exact center (both X+Y) of the stage then the 'ball' should have a tiny diameter of rotation (but contstantly follows the orbit in clockwise direction) whilst if you move the mouse towards the edge of the stage then the diameter of the orbit of the ball will increase.Here is the AS which controls a blank movieclip;
var sp:Sprite = new Sprite(); orb1.addChild(sp) var g: Graphics =sp.graphics
I have created a flash app in which there is a circle with circles plotted along it's circumference, it is rotated when the mouse is moved up or down. The rotation is drawn directly from the y position of the mouse pointer. What I would like to do is grade the movement some how so that the further down the mouse pointer goes the less impact on rotation the movement has.
My current code is like this:
myCircle.rotationZ = e.localY;
Is there some form of math formula I could use which would reduce the amount of rotation the greater the y position of the mouse position?
This is for a personal art project, however I have hit a potential (Actionscript) brick wall!

I have a movieclip instance named "ground" i have it set up so that the ground moves constantly to the left as a scrolling BG. what I want is that when the user presses the "space" button, the ground moves down then back up in a a parabolic path. and it does. but I want the movieclip to stop moving vertically(make dy equal to zero) when it returns to its original y position. how can this be achieved?
Ive got a code to move a MC on the main stage together with the mouse, in the the X axis,. difficult to explain. But now the client wants that this MC movement works only when the Y position of the mouse is over the 300 px. I thought I need a hit test or something elese. Please help. Here is the whole code.
RIGHTNOW, Im doing my game development but I have problem based on my game control.this is my question..
I have two frames. the first frame is on running movement of the character and the second frame is on standing position.This two frames has only one kind of character,but I seperated the two movement in two frames witch are running and standing positon.my problem is how can I do the mouseEvent,if onclick the character will continue on running and if on release the character will do is to standing position.
I just followed this tutorial and I did get how it all worked.. and i got my movie clip flying arround the stage. Then when i tried to apply it to a little project i'm working on, i couldn't get it working. I have a movie clip called mc_main and when i click a button I want it to move - using easing - to a new position on the stage. In the first frame of my timeline i have put this AS:
I am trying to simulate a 3D navigation which changes the movement depending of the x and y mouse position.url...Does anyone know where I can find a tutorial step by step for it or something similar?
I added a Menu_mc on my stage. Initially, this should be at the center of the stage and when I click on it, it will tween on the upper left corner of the browser. However, when I resize the browser, the Menu_mc goes back to the center of the screen.
I have tried separating a different actionscript file where it is specifically for initialization of the object and another one for resizing. And then when I call it on my main AS file it goes like this:
Code: // Add the symbols to stage var Menu_mc = new Menu_MC(); addChild(Menu_mc);
Is it possible to draw motion guide/path for a mouse position based movement?
For example if I have path the is like letter H. I would need to write many clauses/conditions for the borders of the movement. It would be a LOT easier if there would be some solution that makes the object always to stay on the defined path when moving..
I'm hoping someone can solve this headache. Basically, I want a movieclip to move to the position of each of my buttons from any position along my x axis. Therefore, the movieclip needs to 'flip' to face the way it is traveling.At the moment I have the movieclip moving to the mouse x axis when I ROLLOVER the button and stop following the mouse when I ROLLOUT but the code won't flip the movieclip so I must have something wrong...
lets say i have a sprite on the stage and one movieclip inside it. now i want to tween or just set that movieclip x and/or y position according to stage position. so for example i want to set mc.y = - 100; (by which i mean -100 to stage, not sprite which mc is in.)
What i'd like to do is have a menu/site map that adjusts when you click on a certain icon. For example, I have a AS3.0 flash file with, say, 5 keyframes with 5 buttons that are in different positions on each key frame. The buttons are set to gotoAndPlay the various keyframes. I can set up a tween that links frame 1 to 2, 2 to 3 etc. but what I would like is a tween from, say, 1 to 3, then 3 to 5, then 5 to 1 - basically in a random order rather than sequentially through the key frames. I could set each of these tweens up individually but the site is for a portfolio that I would like to keep adding to and to do this individually would mean an ever increasing amount of tweens.Basically, is there a way to get a 'MovieClip' to move from Position A in keyframe 1 to Position B in another keyframe without a set of tween frames? I'm sure this is simpler than I am making it sound but I don't seem to be able to work it out.
I have a clip that rotates to orient itself towards the mouse when the mouse is over a given area. When the mouse leaves the area, the clip snaps back to its original position.
1) the clip snaps directly towards the mouse at the moment the mouse enters the clip; I would like it to actually rotate;
2) the clip snaps directly back to its original position when the mouse leaves the clip; I would like it to ease back into position.
