ActionScript 2.0 :: [MX2004PRO] The Point Of An Array?
Apr 18, 2005
I have been using FLASH for years and I make websites with it as my regular job but I have never had to deal with arrays so never learned them. I really want to, I saw Kirupa's tutorial but I still don't understand what they are for. Could someone give me some examples as to their usage? Why do I need an array? What can I do with them? I am usually creative with my FLASH techniques and I know arrays are useful but I am like a monkey with a revolver...I know they have power, but what are they for?
it's an array within an array, as you can see. However the way things are laid out here isn't as efficient or manageable as i'd like.The second two values, 10 and 0, are actually linked coordinates. When i'm using them, i extract them and use them as X and Y for a point.
What i'm thinking is that this extra step seems like an unnecessary annoyance, and bloats my code.It would be best to simply put a point type variable into tjhe array in the first place. But can i do that? what would be the correct syntax?
I have a source array with simple Point instances in them (just an object with x and y properties). I want to have a resulting array with the cumulative result of calling Point.add() to each of the instances. (e.g. the resulting point object is a result of adding the current point to the total of the points before it in the source array.) is this possible to dynamically do this?
It's been a long time since I've done any work with actionscript, and alas I've forgotten nearly everything. I've tried to look for a tutorial that would explain basic animation with actionscript, but the one that I found on Kirupa was no longer there.
Basically I'd like to do this:On the stage I have a movieclip and I'd like the movieclip to move along the x-axis to a certain point and then back to the starting point again. The moving speed of the movieclip should also be adjustable.
I'm creating a game in flash for a university project, and learning actionscript and programming as I go. I'm very much still at a beginner level - at the moment al I have is some actionscript for drawing rectangles and moving them about the screen. This is what I'm having trouble with at the moment: I have a class called 'Creature', and I want instances of it to interact with each other. I want them to do something when they come within a certain distance of another instance. And I want them to be able to pick a random other instance to get the location of, in order to do something with that information.
What I think I need is: A function for telling the distance between two (x,y) points. A way of referencing the nearest other instance of the class. And a way of randomly selecting from all of the instances of the class.
How to convert 3d point to 2d point? I've found next formula in Internet(camera is situated in origin)
[Code]....
But these formulae give me strange result when z are less than zero(z<0) I need build line from A(100,100,100) to B (100,100;-100) As you can see these equations give really strange result when I try to convert B point in 2D dimension
I have a point which is setted at the border on a component, with changed transform point to the center of a component in order to match the component rotation.
the important part is when i try to get the point XY after rotation - they remains the same as before rotation.
how to get XY, after rotation ( changeing point.rotation property to specific degrees of rotaion )
I am using AS2 with Flash 8 Professional So, my problem is that I currently have a man in the middle of the screen, who shoots a line towards the mouse when I click. However, when I use hitTest to see if the line collides with another object, Flash recognizes the line as a large box if it is diagonal, so the hitTest isn't very accurate. The line only satys there for one frame, so I can't have the usual moving-bullet-style. I am either looking for a way to create an imaginary line with AS from the starting point to the mouse and beyond, and tell whether or not this line intersects with an object... or some other way that I haven't thought of to fix my problem. Keep in mind that the line rotates from a center point towards anywhere around it for 360 degrees.
my preloader bar isn't growing smoothly. it appears to jump from point to point -- and i want to make it smooth. you can see the example here at: [URL] would anyone mind taking a quick look at the file i've attached,
Hi I am trying to create an image scroller that just scrolls images from point a to point b on load horizontally in an infinite loop. I just used a code snippet to move it horizontally but don't how to get it to stop and at point b and loop again from a.
Lets say I have two objects, and I want to use action script to draw a line connecting them, which will update automatically as they are moved/ dragged.Can anyone show me how to do that, and also how to control line's parameters like colour, weight etc?
I am trying to develop a Quadratic Bezier Curve using the graphics.curveTo() method. Initially when i drag mouse to draw the shape, i use start point and end point of mouse to draw the curve line. I assume control point at any position below or up to the line. An draw the curve using this control point. some what like:-
[Code]...
Now i add a tip on this curve segment. I have x and y position of tip. I want to change the curve segment by dragging tip. but now i don't have the exact control point according to tip position. If i use tip coordinate as control point it reduce the height of curve and now tip does not lie on the curve segment. What i have to do is calculate the exact control point on the basis of tip coordinate. But i failed to get this point.
how to use these in order to make an object move from point A to point B in an arc.Think of that classic game where you have to input the angle and power and try to hit your opponent.
I'm trying to figure out how to find a point relative to the center of an object, modified by its rotation. For example, in the attached swf, I've been messing around trying to draw trails to a bitmap, coming out of the thrusters. I didn't have a problem at first, but as the ship rotated, the lines that were being drawn wouldn't remain relative.
http:[url]....
I'm sure this is because I have no idea what I'm doing, and I've just been sort of idioting my way through it. That aside, is there an easy way to find the point I'm looking for? For instance, say I want a point at Y -14 of my ship, but I want that to remain relative to the ship as it rotates.
From the Robert Penner code given in this tutorial: [URL] i was wondering why controlx and controly has to be so complicated. I've tried changing it to just _root._xmouse but it messes up. I don't get this, shouldn't the curve point be the same point as the mouse?
i have this code i found that smoothly moves a box left or right on the screen based on using the left or right arrow keys. i want to use this smooth code but adjust it so on enterframe, the box would move from point a (say 0,120) to point b (0,240) and stop there.no keys used, just working based on entering the frame.how to modify the code below?
Basically what I like to ask is how to move a object from one point to another point based on the point tat you have clicked on a graph. For example, If I click on this coordinate (2,3) on graph, the object (movie clip) will move to that point.
how to get items from an array between 2 points. ie ActionScript Code:array:Array = [mc,mc1,mc2,mc3,mc4,mc5,mc6,mc7,mc8,mc9,mc10] how would i say items 3-7 with out deleteing them or removing them from the array. just to expalin what im doing. i have created a grid and pushed then into a array. i have created a add function which add a movie clip to a certain point in the array specified by the user. but im trying to create a populate cell-cell so user can populate more the 1 at a time. here is the code im useing to add 1 tile to the grid
if i move the cursor to a point A, it automatically moves by itself to a point B. then if i move the cursor from B to a point C, it bounces away to a point D. i stumbled upon this site while googling around. i'm not a techie, but yeah, i can handle word processors.
When I right-click a symbol the options "set transformation point" and "reset transformation point" come up. They don't seem to do anything for me. I thought it would center them or something. This is not the case. I have the white transformation point in one corner in one keyframe and a different corner in another keyframe I click "reset transformation point" on both frames and they don't move.
I have used a method to shuffle a part of a Array, but i noticed that it does not work very well.When i run this method I sometimes get empty array values.So if you would try the example below and test it out some times you would get a right result but sometimes a wrong result.For example when i run this i get in my trace output:
a,b,c,d,g,,e,f (here after the g it goes wrong) a,b,c,f,g,d,e (here it goes right) a,b,c,d,,g,f,e (here it goes wrong)[code]...
I am curious if this is an okay implementation of the Array.filter() method.
[Code]...
I was not able to figure out an implementation of the callback function for the filter() method, where the callback was outside of the getGallery() function. I wonder if there is a way to get the isGallery function outside of the getGallery scope?
I have two arrays. One contains numbers and the other contains strings. I want to do a sortOn(DECENDING) for the number array and then have the string array sort to match. if my string array is
