View 1 RepliesI have some code here for some falling leaves. I was wondering how it can be altered so there is a delay between a group of leaves falling and the next group falling? also to slow down at the end of the fall? [code]
View 9 RepliesI 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 worked on a new Flash project, but I cant seem to find a good solution for how I want my objects to collide. In my project I have: a Ball(moving object) and a Floor(not moving).
The ball is positioned over the floor and drops onto the floor through the gravity that is applied with the code.

Is there a way to have a global gravity in flash AS3. In which you could choose what objects you want to be affected by it? Is there a way to have a block of code that separates moving from still objects and will not let any objects collide(not overlap)?

I am using Box2d 2.02, and am having trouble with setting linear velocity of a body in 0 gravity. When I trace GetLinearVelocity() when left is pressed, it reports the correct vector (-20.0, 0.0) but the body does not move. It is a dynamic body.
Code:
if (Key.isDown(Keyboard.LEFT)) {
if (mover.IsSleeping()){
mover.WakeUp();
}
mover.SetLinearVelocity(new b2Vec2( -20.0, 0.0));
}
I'm making a game were parts of the level are randomly generated and move across the screen and while I have made it so all that works correctly I am having trouble running a hittest on them to allow for gravity. Below is the piece of code attached to the player movieclip that I think is causing the issue (shortened for sake of space)

View 4 Repliesi have a game where fish fall out the sky and a penguin on ice skates has to catch them before the fish get to heavy for the ice, the ice cracks and the ice skating penguin falls into the water and freezes. I have all the code but cant work out how to set the random location along the Y axis for the fish to fall. I have a gravity script but cant work out how to include the random position for the fish. There are 30 fish and i want to be able to have one fish fall wait a half a second and have another fall and so on....until all 30 have been dropped...
My gravity script is this:
ymov = 0;
grav = 2;
_root.onEnterFrame =function() {
ymov += grav;

Anyone know how i could set a random location in this or something similar?

I've made a character, and used the bone tool to make it move in runtime.This works fine, but now I want to add gravity/physics, so I can throw my character and it lands on the ground like a real ragdoll. How do I do this in actionscript 3 ? And is it possible to do this within the fla (no class file).

I have a move that has a bunch of boxes that drop into the screen and bounce with a little gravity at the bottom of the window.
Code:
for (i=0; i<4; i++) {
var clip:MovieClip = attachMovie("circle", "circle"+i, getNextHighestDepth());

I have a file where two objects fall from the top of the stage and bounce and then eventually stop (using gravity and hit test). You can grab the objects (a ball and a box --- each has a button symbol n the movie clip) and toss them and they bounce off each other and off the 4 sides of the stage. The issue is when one of the objects is dropped directly on top of the other object, after it stops bouncing, it slides down until it hits the bottom of the stage (in this case, the box slides down in front of the ball, and the ball slides down in back of the box).

View 1 RepliesCurrently, I'm developing a drag 'n' drop 'snap' game in flash. The meaning of this game is to drag ''crates'' from a boat and load the crates into a train.
What I got working in AS2:
- The crane arm follows the mouse cursor.
- It can drag and snap objects(crates)
But what still need to works is:
- When mouse button on object is released, the object (crate) is still floating in the air. When released mouse button, the object must fall down. (gravity)
I'm just starting out in actionscript 3.0, and I'm trying to create a basic platform game. Since I don't really have time to code it from A to Z, I'm using an 'engine' I found here. I've made a few modifications (mostly deleting stuff I don't need, such as the enemies and the coins). Now I'd like to create a crate that the player character can pick-up, throw, put down and jump on. I've created a new class (Cage.as) for it, based on the player class. When I run the game, the crate is displayed, but it just floats there. I can't figure how to make it interact with gravity (i.e. fall to the ground).
