how to respond when a rectangle hits another rectangle? I already know how to detect the collision, I just don't know how to respond to it. I'm just trying making a simple side-scrolling platform game where I have platforms I can walk on and bump against on all sides. I have searched everywhere and just can't find the tutorials I'm looking for.

View 3 RepliesFor those of you still with me, I am tasked with making some scrollable content in Flash. Load in a TextFile using LoadURL(), then display it. To get the text, we've written our own class TextFieldExtended, which is basically just there to give the textfile location to the constructor and then have the class do the various steps of getting it and loading it for you.So I needed to get a Scrollbar, which I got hereThe thing is, it works with Sprites.After trying to get it to accept TextFieldExtended, I bumped into a block, since the scrollbar relied heavily on a Sprite property that TextFieldExtended didn't have or could have.
So I tried adding the TextFieldExtended instance to a Sprite instance using addchild.A problem occurs here that I do not know how to handle. It seems that a Rectangle is drawn and the Text is drawn on that. I say this because the scrollbar moves the Rectangle up and down a bit, but the text doesn't scroll, just the Rectangle it is positioned in and the text then moves along with it.My question: can this be fixed, or is does this implementation of scrollbars need a lot of adaptations before this is possible?

Assuming that works in detecting the collision, what would I use to actually stop the rectangle from progressing through the wall?
for the past two weeks I've been working on coming up with a collision detection system for my game in flash CS4. No matter what I try for some reason I just can't seem to do it, and I don't know how to fix it. This has never been an issue for me, I would even settle for basic rectangle to rectangle collision if I could, but no matter what I do I end up screwing it at all up. Somehow the collision detection either doesn't work at all, works for one side and jumps the guy through the wall on any other side or I think at one point it worked for two sides as long as I didn't hold down more than one movement key.
I've constantly scrapped what I've done over and over, right now I have no source code to present. I'm totally lost and confused, and my deadline for getting this done is today in a few hours. I really wanted to figure this out on my own but honestly I just don't see what I can do, I've got sphere to sphere collision detection working perfectly for my player and other spheres, but the walls are squares lined up to form long rectangles, and I just can't seem to get it to work. I'm dynamically loading the square-wall blocks as tiles to form a dynamically loaded map, and then I'm iterating through each individual block to determine if collision has occurred with the player. I think somehow I'm not managing the results right, or maybe I somehow need to be able to determine which direction the player hit the wall from, but I just don't know how to do it.
I've been staring at the screen for the past 3 hours trying to work something out but nothing is coming to me, example from a flash-type game or something similar I would be very grateful! (I've done this countless times in C++, C#, and java. I don't get what is going on in flash :-(((( )
I've been trying to fiqure out how to use the collision detection on one side of a rectangle differently then the other sides. for example: Mario mashes boxes with his head, by standing under the box and jumping up. (I'm refering to just the Super Mario Bros. game). If Mario hits the box from the sides or top nothing will break or come out of the box. How do you do that in Actionscript 3.0.

I'm trying to make a labyrinth type game where you control a narrow spinning rectangle. And you have to navigate it through a course without touching the walls.
I've been looking for 2 evenings now and I just can't find any type of collision detection that will do this. I'm quite a novice so I'm beginning to wonder if this is even possible for me to accomplish. All the tutorials I find are assuming the player will be a square, circle or a point.
I am trying to convert a rectangle(actually multiple rectangles) to a curved rectangle. I think it should be pretty easy but I guess i am stupid. Basically I would have a start position and stop position (many of these), and they would be converted to curved rectangles and follow in a cicrle around.
View 0 RepliesI would like to create a rectangle inside of a rectangle, starting approximately 15% inward from the right side of the other rectangle.
I know how to create rectangles with:
Code:
var newHotRect:MovieClip = new MovieClip();
newHotRect.graphics.beginFill(0x00FF00);
newHotRect.graphics.drawRect(0, 0, 100, 100);
addChild(newHotRect);
But how would I make another rectangle on top of that (the black one pictured) that is approximately 15% from the right?
I toyed around with .right, and .bottomright with no success. Can anyone lead me in the right direction? or even finding the x and y of the upper right or bottom right side of a rectangle?
I do know how to use the oval / rectangle and oval / rectangle primitive tools in the tool bar and find them quite useful, but one thing I find confusing is. A oval / rectangle primitive object can be edited later but the oval / rectangle can't. So the point is,how do we use them properly ? when to use ? Why does Adobe Flash still keep the oval / rectangle tool in their product instead of removing them with the oval / rectangle primitive tool ?

My question applies only when I work in 16 bit system resolution, so when I apply some text and apply 'Anti-alias for readability' with embedded chars, there is some strange filled rectangle showing around the text box. The same applies when I add any kind of filter to a text or image. You may see the exact problem by clicking on the link below: http:[url]....
- Notice the rectangle around the text boxes ('anti-alias for readability' applied, it doesn't matters is it static or dynamic text)
- Notice the rectangle around the middle dark-gray box with glowing effect applied
I will say again, this problem occurs only in 16 bit system resolution, it is not applying in 32 bit.

View 1 RepliesI'm working with BitmapData.getColorBoundsRect and it works so far fine for me. But what if I want to find more rectangles with the same color? For example: I got a BitmapData with 3 red rectangles. If I use getColorBoundsRect I get the whole area including the 3 rectangles. Is there a way to separate each rectangle?

I would like to have an invisible drop target so I can dropand item and have it go to another part of the training. However,if I create a rectangle as a sprite and don't fill it in, itdoesn't recognize it as an area apparently because nothing happenswithout a fill color. I tried just a regular rectangle, shape, etc.
View 5 RepliesI am trying to make a dynamic drawing tool for rectangle like this link : [URL]
I was able to make a line tool.
I would like to tween between a short rounded rectangle and a tall rounded rectangle. (I only want deal with the height - no other parameters). I am programming with ActionScript 3. My tweening engine is TweenLite.I have been tweening a sprite that contains a rounded rectangle. The tweened sprite produces distortion. I suppose that I have been scaling the original image, rather than the height of the rounded rectangle?Here is a simple example of my code:
Draw the rounded rectangle:
roundRect = new Sprite();roundRect.graphics.beginFill(0x000000);roundRect.graphics.drawRoundRect(0,0,50,15,4,4); //Original Height: 15roundRect.graphics.endFill();addChild(roundRect);
Then I listen for a mouse click event on the rounded rectangle.The mouse event triggers a function with the following code:
TweenLite.to(this.roundRect, 1, {height:120}); //Final Height: 120
I would like to tween the height of the rounded rectangle itself. I would hope that this would not produce the unwanted distortion.
In Flash CS4, when I draw a rectangle (or circle, or anything) with a color that has 0 alpha, nothing is drawn. Also, if I select a piece of drawing and change the color to 0 alpha, the drawing (e.g. rectangle) disappears!I know I can draw a non-transparent rectangle, convert it to movie clip and set the movie clip's alpha to 0, but I'd like to avoid this.

View 3 RepliesI'm making a flash game (pac-man) and i have designed a level (the walls). Now when i convert it to a symbol flash makes it a rectangle (he counts the gaps between te wall as part of the symbol). This is a huge problem because when i want to test collision between pac-man and the walls in actionscript he always "hits the wall" because he is inside the object. Is there a way to convert only the walls into a symbol.
