ActionScript 3.0 :: Circle Circle Frame Independant Collision Reaction?
Apr 10, 2010Trying to do circle circle collisions via math which I'm really having trouble with. One circle (player) just moves from keyboard. The ball reacts to the player. All the code shown is in my players class and I passed in a reference to the ball.
On my enterframe I have:
Code:
var xmov1 = xSpeed;
var ymov1 = ySpeed;
var xmov2 = ballRef.xSpeed;
var ymov2 = ballRef.ySpeed;
[code]....
Perhaps I'll go with a box2d equivalent instead of trying out my own physics shenanigans.

I have searched everywhere and just can't find the tutorials I'm looking for.

Actionscript 3.0 :: Flash - Sphere To Rectangle Collision Detection?
Apr 19, 2010for 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 :-(((( )

Actionscript 3 :: Use The Collision Detection On One Side Of A Rectangle Differently Then The Others Sides?
Jun 23, 2011I'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.

View 1 RepliesActionScript 3.0 :: Collisions Between Moving Circle And Rectangle Object
Oct 9, 2010In AS3 is there an easy way for collisions to take place between a moving circle and a rectangle object. A moving circle has a direction and you need to know how it collides with an object rather than knowing it just hits. In .net you use a points test where you test several points around a circle to see what hits an object and then you can work out what direction it will bounce off.

View 3 RepliesActionscript 3 :: Scrollbar With Sprite And Rectangle Won't Move Text, Just The Rectangle It's Painted On?
Mar 8, 2010For 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?
ActionScript 2.0 :: Calculate The Direction And Speed A Circle Has After Colliding With A Static (non-moving) Circle?
Mar 8, 2005I'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?

I know how to create rectangles with:
Code:
var newHotRect:MovieClip = new MovieClip();
newHotRect.graphics.beginFill(0x00FF00);
newHotRect.graphics.drawRect(0, 0, 100, 100);

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?
