How to you calculate the total rotation of an object in either direction?
I need to end up with a number of total radinas(or degrees) that is posotive or negative depending which way the object was rotated.
I have the coordinates of a player and another object. Both are with geographical coordinates (Latitude and longitude). I have also the direction in what the player is facing (compass). How can I calculate the angle to the other object from the player direction? e.g. I want to know if the object is to the right/left of the player and how many degrees.
View 3 RepliesI am tweeing a bunch of rectangles randomly on stage.
Code:
TweenLite.to(thumbArr[i],1,{
x:Math.random () * (stage.stageWidth - thumbArr[i].width),
y:Math.random () * (stage.stageHeight - thumbArr[i].height),
rotation: Math.random () * (60) - 30});
the problem is that after I added random rotation (between -30 and 30 degrees), the corners of my rectangles are still sticking out of the stage at the end of the tween.
If I trace objects width and height after the rotation I get the new values but this still doesnt help me because I am tweening to that rotation.
Code:
mc.rotation = 20;
trace(mc.width);
trace(mc.height);
I am tweeing a bunch of rectangular shaped objects randomly on stage.
Code:
TweenLite.to(thumbArr[i],1,{
x:Math.random () * (stage.stageWidth - thumbArr[i].width),
y:Math.random () * (stage.stageHeight - thumbArr[i].height),
rotation: Math.random () * (60) - 30});
the problem is that after I added a random rotation between -30 & 30 degrees they still stick out of the stage a little.how could I calculate width & height of the these objects based on their final rotation so they dont stick out of the stage?

View 3 Replieshow to build a timeline scrubber that can scrub more than one scene.
1. Scene 1 had 20 frames
2. Scene 2 had 20 frames
3. On scene 1 I put the slider that scrub the timeline. The totalFrames; sum all the frame from all the scene.
4. When i scrub the slider to frame 21 error occurred saying that the slider couldn't be found. So i paste the slider in scene 2.
So how to continue scrub on scene 2? How to make a slider that can scrub all scene and move along showing the current frames?
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.

I have a MC(a small army tank) that I can rotate using the right and left buttons. I want to make it move forward when I push the up arrow - The Catch . . . I want it to move in the same direction it is currently rotated. Example: I rotate the tank 10 degrees and then I push the up arrow off it goes in that direction.

I'm having a bit of a problem with my script. I currently have a square that moves across the screen. There is another square on the stage as well. I want the other square to call a hitTest with the first square (that moves), which we'll give an instance of "hero". The hitTest should make the "hero" (or first square) rotation a specific degree (in this case 30) and then move him in a specific direction, either up, or down the y-axis or left or right on the x-axis. This is my current code, attached to my second square.
onClipEvent(enterFrame){
if(this.hitTest(_root.hero)){
_root.hero.rotate += 30;

I want to make a movieclip moves smoothly and when it changes the direction, it can turn smoothly but not a sudden turn, I try out the code below. and the truning is odd:
this.rotation = (Math.atan2(targetY-this.y, targetX-this.x )/Math.PI)*180;
I am very new to flash, I got a player, and the idea is for a top down shooter kind of thing, I got the player to rotate with left and right, and its rotation equals its direction, now how can I make it move forward in its current direction when I press up?
View 3 RepliesI have a rotation value in degrees(0-360) and a value for magnitude, ie (1-10 pixels per second).

I am using FLEX version 3.0I want to calculate the total working hours. I am giving you the details and what i have done in it.
var a:Number = 2.00;
var b:Number = 2.00;
var c:Number = 1.45;
[code].....
I would like to know if it is possible in flex to do the following actions. I have made an HTTPService to a MySQL database, table: orders_open and it has columns
Id | product | price | units | total_price | customer | waiter | printed | paid_cash | paid_card | date
The datagrid is filtered by the customer column. Default value of | printed | paid_cash | paid_card is 0
1)How can I make flex take the price and units and calculate automatically the total_price? In the datagrid and update the database lines when I save.
2) Sum up all filtered total_price �s and give the bill_total in a text field
3) When paid, print the ticket | product | price | units | total_price | and the bill_total in a printer
My code has been created by Flex (create application from database)
I'm developing a game atm, and I need some help on the mathematics/coding of colliding circles (and their change in x/y speed). What i need to know is how to calculate the direction and speed a circle has after colliding with a static (non-moving) circle. I know how to detect a collision between the two, but I'm not sure about the maths I need to give the circle the right speed and direction after the collision
If i do know how far away the two circle-points (in the middle of each) are to each other (in both x and y coords) would it be easy for me to find the new speed and direction of the large circle in the example above? I know that I somehow should use the angles to pretend the circle hits a flat "wall" (as it only hits one point), and then calculate the new speed/direction. My only problem is that I'm not sure how to decide the angle of this flat "wall" and how x and y speeds should change when colliding with a wall that is angled. Does anyone here have any insight, links or tips on how I can du this?

View 1 RepliesI'm still new to AS3, and I was wondering how to make an object point in the direction of another object and move towards it if they are a certain distance from one another. I haven't been able to find out how to do this from the Adobe devnet, so I thought I'd ask here.
View 1 RepliesI have a papervision camera of which turns using keyboard input, I have a radar of which I would like to orientate to direction when the camera turns.I have it all working apart from mapping my (camera) DisplayObject3D.rotationY to RadarInterface.rotation correctly.The camera (or any 3d object) works with values I'm finding hard:Clockwise: 0 to 89, 89 to 0, -0 to -89, -89 to -0 doing a complete 360.So if I were to turn 180 degrees I'd go from 0 to 90 and back down to 0 again.

is there a easy way to make an object move along the x axis in one direction then when it reaches that direction it moves back. with a smoove movement.
