ActionScript 3.0 :: Graphics - Paint (change Color) Inside Of Circle When A User Draw A Circle
Aug 24, 2009
I`m working on a app that you can draw lines.....like circles, rectangles... my problem is when a user draw a circle for example....i wanna be able to paint (change color) inside of this circle. I`ve tried working on Shapes with cacheAsBitmap = true and Bitmaps with BitmapData but it doesn`t seens to work.
My basic requirement is to draw a circle inside a BorderContainer with the layout set to BasicLayout.I run this method in the CREATION_COMPLETE event of the BorderContainer object.[code]I know I must be missing something VERY basic here. Can I just draw like this OR should I draw in some other event? I know that I can create a Ellipse object and easily add it to the border container but I would like to know how I can do this using the graphics object.
I need draw rectangle with two circle holes inside. The problem is in circles interception. I want them to join together and cut from background, but they seems to be XORed:
here getCirclePath returns object with points to draw polygon which looks like circle. Also I tried different combinations of GraphicsPathWinding constants, but no luck.
how to draw two intersecting circle holes in graphics?
Trying to draw a triangle and then fill the color inside using the paint tool. I am not able to fill any color inside. Made sure the lines are overlapping, tried using the fill large gaps, made sure alpha is set to 100%.
I've a tiny problem. I want to change the color of a circle through actionscript. Is it possible? It would be fantastic if something like this could work:
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?

Trying 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'm trying to build a circle using lines. each line starts in the centre of the circle and is as long as the circle's radius. using a loop along with sine and cosign waves, i can build the circle using the sine and cosign to mark the coordinates of the lineTo parameter.
my problem is with the line thickness parameter of lineStyle. i would like the ends of the lines to match up perfectly, no matter how big the circumference of the circle, but i can't figure out a proper method for the line thickness.
//this is what makes sense to me, but it still creates some gaps lineThickness = 1 + (((nRadius * 2) * Math.PI) - 360) / 359; for(var i:int = 0; i < 360; i++)
[code]....
to make the ends of the lines meet up at the circles circumference, without any gaps, i need to widen the lines to fill in the space that's remaining. what makes sense to me, but doesn't work, is to subtract the 360 from the circumference, then divide that number by the amount of empty slots between the lines (which is 359) and adding that number the the thickness of 1.
what's concerning me is that the lineStyle thickness parameter is a Number, but seems to take only values between 0 and 255, so i'm not sure if a floating point number like 1.354 is a valid thickness.
Here I what i need is : Start drawing first circle and when first circle is on half way, Start second circle.same way second and third circles. and after completing 3 circles, just gotoAndPlay 2nd Frame .
I am making a simple drawing application, and i have come across a problem. Im not very good with trig at all so i got the code for drawing a circle and customised it and it goes a little dodgy. Could someone tell me why it is happening, and how i should fix it?
I need to draw a circle like a pie chart. But I need the circle to only go around about 2/3's or whatever I choose. I've tried the 'curveTo' method but that didn't work. It makes the circle more bulged and not round like a circle.how to make a perfect circle with a slice taken out?
using action script how to draw a semi circle...i need to add tha semicircle in another circle the circle looks like this ![alt text][1] how to draw a semi circle inside that circle
i do not want to draw a circle on the same layer the background is. So how can i separate background layer and drawing layer? using graphics.drawCircle to draw circle
I have a simple three ring animation where the three rings fade in and out.On the stage the rings are a perfect circle, in the publish preview they look fine, but once I publish the SWF, all of the sudden the rings are not perfectly round anymore.
They are almost perfect but right at the top and bottom there is just a small portion which has sort of "flattened out"...
I bought a Flash video tutorial online for Animating and the FIRST step is to create a circle with the circle tool, and the guy does it online, and it fills itself in. I repeat his actions exactly and I cannot get the same result at all. I just get a circle.
I have two MC's, circular in shape. One of the circles is stationary and you can drag the other. I'm trying to get the moveable circle to be able to move around the circumference of the stationary circle, but not overlap. I'm able to detect when they overlap, not using hittest. I just can't figure out how to code it so that the draggable circle can't be moved over the stationary circle.
I have been trying to get this right for hours now it cant be as hard as I am finding it! but basically I have a circle and in that circle is a circle and all I want is for the inner circle to not be able to leave its parent. that's it but I just cant get it to work.
i have the custom flv player which reads an XmL and draws circles on Flv video. Postion and time is specified in the XML. I did calculation with as3 getTimer() function. It works fine, no matter how long u pause and then play again. Circles are shown at right time.Now i have two problems
1- How getTimer can be reset?? it is required when user is allowed to play another swf..
2- Is there any other way besides getTimer calculation. I am not using Timer Class as it is Dependant on Frame-Script Execution time and may yield wrong result so this is not as accurate as getTimer() function.
3- As i am using Custom Slider , so i have to do calculations each time when user click or drag slider w.r.t getTimer() function and then subtracts seconds and all that. but again it goes very hard when user plays another swf as my calculations are based on getTimer() Funtion.
I have a requirement wherien a semi circle has to be drawn. The circle radius can be chosen/varied by the user. How can i do it dynamicaly using action script.
