Is it possible to test if a sprite (or movieclip) is located at a set of coordinates? If a sprite is located at the coordinates, can you retrieve it's instance name? If no sprite is located at coordinates, can you output a value?
View 1 RepliesI need tp set the y coordinate on a sprite's rightmost coordinate. That is, usually when we set the y coordinate that's the lefttmost side of the sprite, and the sprite starts there and goes to the right of that point. I need to reverse that. The reason is because I'm putting text into it and it's going to the rightmost side of a box, so it can't overflow to the right.
View 2 RepliesI have a task: I need to place about 100 sprites on one canvas (with prepared grid on it). I need to place them as invisible (circles) stones, on the board, and make visible only on mouseover. The problem I come across is following, I can't place those objects accurately into the nodes on the grid.

I was trying to convert global coordinates to local coordinates of a UIComplenent in my flex project using below code using below code
var gp:Point = new Point(e.stageX,e.stageY); //global point
var lp:Point = uic.globalToLocal(gp); //local point
uic is UIComponent in which I have subclass of Sprite for drawing something I have set the sprite's mouseEnabled and mouseChildren to false to not interrupt the mouse event. above code is within uic's mousemove event where I was tracing the gp and lp gp was giving correct value and suprisingly lp was giving negetive values. when I move the move to the top left corner of uic i expect lp to be 0,0 but it is giving the -width of of uic. I broke my head for hours and ended up finding an alternate by using offsets. Infact my original code was much simpler like this which was same issue
var lp:Point = new Point(e.localX,e.localY);
I am not sure what exactly is causing this problem. the workaround had lot of issues and it creating a mess in my rest of the algorithms.Just now I found even more interesting thing (which is actually weird). for some reason I went and create a new lp2
var lp2:Point = new Point(e.localX,e.localY);
now surprisingly it was giving correct values as expected and I went back and changed the code as
var gp:Point = new Point(e.stageX,e.stageY); //global point
var lp:Point = uic.globalToLocal(gp); //local point
var lp2:Point = new Point(e.localX,e.localY);
var lp2:Point = uic.globalToLocal(gp);
now it is expected to have all the lp, lp2 and lp3 variables to be same but weiredly lp two is giving wrong value and lp2 and lp3 were giving correct. I am suspecting using the variable lp has something to do. I am not sure about that but above proves it so right now I am using lp2.
I was reading the 'Isometric Transformations' tutorial by Danko Kozar and I have a few questions. I understand what all the code does, but not how it does it. First of all, how does the following code work:
transforms x,y,z coordinates into Flash x coordinate
xFla = function (x, y, z) {
// cartesian coordinates[code].....
I understand that it converts 3d coordinates to 2d coordinates, but I don't understand how. What numbers whould be punched into x, y, and z to acquire certain desired effects?Also, what's the difference between moveTo and lineTo:
red line
style(1, "0xFF0000", 100);
plot(0, 0, 0);
draw(200, 0, 0);
Im making a little app in flash using papervision I want to make a regular movieClip show up in the same place as a papervision object. The coordinates seem like perspective is affecting the number displayed.
View 2 RepliesI created a class, extended the sprite class, and now in the constructor I am trying to set the Sprite's width and height properties which are inherited from the DisplayObject. However, after I set this.width and this.height, and print the values, I get 0 for both.
What the heck is going on? When I view the livedocs I see that DisplayObject has width and height listed as public properties. I have been able to instantiate a Sprite directly, and set the width and height after it's been instantiated, so I don't get it.
package {
import flash.display.*;

I'm doing a simple rotation on a sprite but there's a weird behavior where the sprite does not rotate around it's top left. I think I'm rotating along the top left of the test class instead of the sprite child. I would like to rotate the rectangle around it's top left corner (kinda like a clock hand). The code is pretty short so I'll let the code + pictures explain my problem:
package
{
import flash.display.Sprite;

I've read a lot of stuff about rotating around a fixed point, I've tried doing it with movieclips instead of sprites, I even copy pasted a tutorial on rotation and nothing works.

Then the numericStepper is drawn as if it is squished to 20% its normal height. If I pre-set mySprite width and height before adding the numericstepper, the trace output is 0,0 after adding it and it is not displayed at all. Is there some way I can make the sprite only adjust to correctly fit the numericStepper OR resize it afterwards without distorting the numericStepper component?
Both of sprite.width and sprite.scaleX can be used for scale a sprite. Is possible sprite.scaleX depends on screen size?

Everytime I google this question I see confusing information about masks and blends, none of which seems to directly apply to what I think should be an easy thing... There are three Sprites involved here...the lowest layer sprite is pretty much a background. I want to overlay a translucent Sprite on top of the background and then I want the third, top-most Sprite to act as a hole, so that the area inside the third Sprite is completely transparent, so that the background sprite is completely visible. How would I go about doing this dynamically (i.e. dynamically drawing the masking sprite and hole using the Actionscript graphics calls)?

View 1 RepliesIve got a question that feels like it should be easy but I cant figure it out. Suppose I have 2d grid of square sprites on the stage, lets say 20 by 20 (400 sprites). Another sprite moves accross the stage on top of the grid. The moving sprite and the 400 sprites below it share a common parent. So heres the question: How do I find out which of the 400 sprites the moving sprite is currently over? And heres an extra wrinkle: I lied, the sprites are not square they are of differing shapes so I cant do a simple math calculation.
All I can come up with is something like hitTestPoint(), but then I would have to call it 400 times wouldnt I? That is probably the most inefficient way to do things. Is there a function like whatsUnderThisPoint(p : Point) which will return a list of every sprite on the display list that contains p?
not sure if this is possible but i'd like to get the X,Y coordinates of a button I drag. here's my problem:

I am trying to change the cursor with coordinates.
I have attached the cursor to the mouse, which is a Red Circle
what I want to happen is when it gets beyond the half way point on the screen for it to turn blue.
I can do it as a rollover but I need to make it to it with if statements and coordinates.
Below is the code I have used to attache the cursor to the mouse
circle_mc.onEnterFrame = function(){
this._x = _xmouse;
this._y =_ymouse;
Mouse.hide();

How can you get x and y coordinates of an instance? My instance is called "rock". This is what I have tried:
PHP Code:
onClipEvent(enterFrame){
trace(rock.x);
trace(rock.y);
}
but it does not work.Next, how can I make this instance go up by a certain angle?
I'd like to use the x and y mouse coordinates as variables in a program. I'm very new to Flash and ActionScript and I'm not even sure which classes I need to import or which listeners or handlers I need to use.
View 1 RepliesWe have a client server architecture where a C++ server talks to Flash clients. I'm developing the server and would like to send through tcp an xy coord to simulate a button press where the receiving flash client would find the topmost visible object at that coord and send a mouse event to it such that we could simulate play without a human present. I'm told this is incredibly difficult, but it seems to me that there must be a way to do this. Am I off the mark? Or is there a mechanism in flash to iterate through all objects regardless of parent child relationships to find a visible button at an x, y coord and signal a press event?
View 2 RepliesI've been racking my brain for the last week, and Im trying to use a map to zoom into certain city locations on the map. I believe each city locatio needs to be its own mc on the map, but don't know if I need to zoom into the coordinates of that mc? Here's what I have so far which zooms in on the appropritea x/y coordinates. Does anyone have any advice as how to change this or some other way to zoom into certain locations on a a map?

This code below works, but I'd like to modify it so that if my dragged item passes over a region in the x coordinates. So if I pass the dragged item over the range of 600 - 700 then it would play the frame labelled "square", and when it passes out of that region, go back to play the frame labelled "circle". So realy I'm asking how can I modify the <=600 to instead 600 to 700, and else refer to circle.
if (me.x <=600){
me.gotoAndStop("Square")
} else if (me.x>= 700){
me.gotoAndStop("Circle")
}
How i can when someone click on button "Start position" to go on 0x 0y coordinates
