I have a 3d projectile game I'm working on. I want to check if the projectile moving down the z axis hits wall on two sides. The walls are set up like this:
leftWall = new wall();
leftWall.x = 10;
leftWall.y = 360;
leftWall.z = 230;
leftWall.rotationY = -95;
How to do collision detection in this 3d space?
I've found the BitmapData.hitTest() function very handy, but limited for my purposes. I need to figure out at exactly which point the two images collide (in any coords system,really), since their behaviour will change depending on the angle of the surface hit
View 9 RepliesI want to check a hit test between a point and a png bitmap with an alpha channel. I know bitmaphittest is for 2 bitmaps. Hittest is for 2 bounding boxes and hittest point is for a point and shape, but it doesnt work with a alpha channeled bitmap. So what do I use to test a point against an alpha mapped bitmap?

I created kind of drag and drop game: i have cards that should be placed on squares.
in case the card touches any square, the square changes it's color. the problem occurs when the card touches 2 squares at their middle: they both change their color.
in fact, I need that only one of the square will change it's color, and it should be the square that the card touches it with "the most of him". i thought of using the hitpoint but i know it won't work, because in case the card touches both square in the middle it won't work..
I have a timer and a dynamic textfield wich displays the time. Everytime my movieclip hits an enemy I want the timer to add 4 sec. to the current count. I would like to know why this isn't working:
timer.currentCount + 4;
(does nothing)
timer.currentCount += 4;

I'm building a a space shooter "Defender" type game, and I'm having a problem with the hit test. My laser hits the enemy (which a duplicate). Enemy movie clip goes to it's frame to which a short explosion animation. The hit test works fine, but since there is more than frame in the "enemy" movie clip, the hit test cycles through every frame of the "enemy" clip until it passes through it's boundaries. Is there a way to only have it hit test with only the first frame of a movie clip?
This is the script on my laser movie clip that performs the hit test:
if(this.hitTest(_root["enemy"+i])){
_root.score+=100;
_root["enemy"+i].gotoAndPlay(2);
this.removeMovieClip();
Non-programmer here, struggling with having to now (finally) work in AS3.I've looked around, but can't find something similar (or as simple) as my old AS2 scoring - hitTest method was.Problem 1: my converted AS3 game does not hitTest or score.[code]I have a Dynamic text box on the stage named "scorecounter" which is now displaying "0" when the game plays. This is correct.When the gun (mouse) is clicked, we then tell the "hittest1" MC to play, which will detect hits. All Correct.[code]The hittest1 MC plays, and checks if the "cursor" MC was touching the "bug1", and tells it to animate (splat) All bug detections are listed in the hitTest frame - "bug1" through "bug30", ie. the code below x 30. This Fails - maybe because the hitTest MC lists all 30, and not all bugs are visibile at once, some are hidden until required later in the game?[code]Then on the last frame of the "bug1" MC (frame 10), it tells the score to add one. Also Fails - maybe because of errors above, nothing is being processed now.[code]
View 5 RepliesI am new to flash and im trying to make a game. Im stuck on hitTest. I have many black boxes falling down and I want the game to reset when the black boxes touch my red circle. I used this code for my boxes:
[AS]
this.createEmptyMovieClip("canvas_mc",10);
myInterval = setInterval(addbox1,500);
function addbox1() {
[Code] .....
My red circle is controlled by the mouse. The code for that is:
[AS]onClipEvent (load) {
startDrag(this, true); }[/AS]
I need to create a game where you drag and drop clothing onto a body that snaps into place then when the body is fully clothed you click a button to see if the clothing you selected is correct. There will be 4 different areas of clothing with 3 options for each area, one for each area is correct. how to achieve this? In either actionScript 2 or 3.
View 3 RepliesI posted a bit earlier about some problems I had with a game I'm trying to do.[URL].. My first and main problem is that the ennemies are going through the walls. I can do a hiTest like with the player so that the collision is detected, but I don't know how to make the ennemy change direction. I thought it would be quite simpler if the ennemies could not move simultaneously on the x and y axis, but don't know how to do it. (then they would only need to make a 90 degrees turn)
Second problem is the hitTest for detecting collisions with the ennemies. It seems like I'm not able to do it. There is the part which I thought would be good at the end of the script in commentary. Third problem, which is the least important in my eyes is that we see the ennemies even if the "flashlight" is not aimed towards them.

i am working on a game called "virus". you click somewhere on the screen and the virus goes to where you click. you have to dodge random moving white blood cells, and if you hit them you lose. everything is working. except for one thing. scoring.
i have made a movieclip with a dynamic textbox in (score), and in the movie clip there is a section where the number in the score textbox goes up really quickly, a section where is goes up medium, and a section where it goes up slowly. i want to make it so that when you get closer to the center of the movie, for the score to go up quicly, and slower as you get further out. i have tried hittest with movie clips in the centre of the stage, but it doesnt seem to work.
I made a game and I like to add scores. For now I have:
Code:
if (eval('ball'+curball).sunk) {
counter = counter + 10; how could I show points (counter) in a game?
I am wondering how to write code so that once a character reaches a certain 'end mark' it will trigger the next frame/level. I am using Flash CS5, but I have primarily used it for animation. This would be my first leveled game.
View 2 RepliesI'm making game, where I must collect points. In end menu screen, i want that if my score's over 200, a next level button will be visible. Now it's visible every time when timer's out. I have tried this code
if (score < 200){
this.visible == false;
} else
if (score >=200){
this.visible == false;
}
My projectile begins to arc but then moves to the right uncontrollably and does not ever go down.[code]...
View 1 RepliesI'm designing a platformer game, in which the code is all held within the character MC. I want to pause the game using something like 'delete this.onEnterFrame' as a start point to terminate code. The code layout within the character is like so:
onClipEvent (enterFrame) {
...
this.onEnterFrame = function(){ //within clip event
...
if(btnon == 1){ // when button pressed(on stage)) global value of 1 is true
delete this.onEnterFrame;
}...}}
Due to the fact its within a clip event structure, it doesn't pause it, instead it slows everything down. Would I have to construct all my code in a frame layer or can I still use an MC to terminate this?
I'm creating a game where you have a cannon at the left edge of the screen. I want to be able to fire a cannonball from the cannon in an arc so that it intersects where the mouse pointer is on the screen.
I've seen a few examples that move a projectile in an arc from point a to point b, but what I need is for the cannonball to first move along the axis of the cannon itself, it's no good if the ball leaves the end of the cannon at a different angle to which the cannon is pointing.
The only force acting on the ball will be gravity and it's starting velocity.
Also to complicate matters, I need the cannons angle to change according to how far away the mouse pointer is from the end of the cannon, so if the pointer is far away than the cannon will point upwards say at an angle of 45 degrees, but if the pointer is very close to the end of the cannon then the cannon will point directly at the pointer, this I've more or less already got working by just getting the distance between them and then dividing it by a number and subtracting it from the rotation value of the cannon, but it's a bit of a rough way of doing it.
EDIT Using the code below I've managed to the line in the screen shot below. But as you can see it's not the trajectory I need, I need something more like the red line I've put in.
And here's how I've implemented the code (probably wrongly)
public class GameTurretLine2
{
var rt:Object = null;
[Code]....
Also for some strange reason, the line created by the code flips, from how it is in the screen shot to an indented code (y flipped) just by moving the mouse a tiny amount, so as you move the mouse the line jumps everywhere.
I have a flash 8 movie that uses actionscript to create a projectile, kind of like a ball being fired from a canon. I want to create a line that follows and draws the path of the projectile.
View 2 RepliesThis is my first week of learning Flash and ActionScript, and because I don't have a good ActionScript book yet, I've been reading several basic Flash game programming tutorials online and doing my best to understand and learn the syntax and methods. After successfully creating "my" first Flash game (a space-shooter from the great tutorial on this website), I decided to set a high bar for myself and try to make a top-down shooter which I can expand on as I learn more.
My problem is that I simply cannot get Flash to recognize my "bullet" movie clip symbol in the library, place it by my character's gun with correct rotation, and finally shoot it off into the distance. The gun is part of the same .png as the character is in, so it is part of the same symbol ("player").
Below is the code I am working on for the shooting code:
Shooting Code: (Applied to my "Player" movie clip symbol's "Actions")
onClipEvent(load)
{

In my Flash scene, I have a "Crosshairs" movie clip symbol which I have successfully gotten to replace the hidden standard mouse cursor, a "player" movie clip who can move around the scene while always facing the crosshair, and a "bullet2" movie clip in my library. Both the player and bullet MC's have identifiers of the same name applied to them.
if I make a Super Mario platform jumping game - should it be bottom left ie: the hitPoint of his feet and the platform he lands on.
View 3 RepliesNeed to make it so when you hit <control> it will place the bullet but if you hit <control> again it will duplicate it instead of moving the bullet from where it was before. I am trying to find a code that I can look at for research but there arent any AS 3.0 scripts or fla files to DL. The bullet does not need to move or anything, just places the bullet.
View 0 RepliesI need to build a flash learn game to my students. It is to explain the angles and phisics over the billiard/snooker Table. Something similar to this: [URL] The only thing I can do until now is drag the ball! My doubts are:
- How to make the stick move with the center in the point near the ball;
- How to draw the yellow line;
- How to calculate the corners;
- And in the last, how to move the ball with accelerated motion when press a button.
I have a projectile that generated by this code:
//initial code
bullet1.x = bullet1.x + (cur_speed_x / 10);
bullet1.y = bullet1.y - (cur_speed_y / 10);
cur_speed_y = cur_speed_y - g / 50;

I want the projectile to keep the same path but just move faster without having to increase the frame rate of the movie. Where I should increase the motion in the above formulas to get that to happen?

i just would like to know how to create an "hitTest" script inside a movieclip that is actually part of that hitTest code?I mean... I have mc A, and mc B. and the current hitTest code im using (that is on the timeline) makes mc A, destroy mc B when collide with it... but there are many mc B on the stage (with the same instance name) so, when mc A collide with one mc B, it destroys ALL mc's B... but i want it to destroy only the mc B that he collides, not all the others... maybe an hitTest script inside a movieclip B would work (somethig like "if MC A hitTest ME = i die" (not all the others)).

It's been a long time since I've done any work with actionscript, and alas I've forgotten nearly everything. I've tried to look for a tutorial that would explain basic animation with actionscript, but the one that I found on Kirupa was no longer there.
Basically I'd like to do this:On the stage I have a movieclip and I'd like the movieclip to move along the x-axis to a certain point and then back to the starting point again. The moving speed of the movieclip should also be adjustable.
I'm creating a game in flash for a university project, and learning actionscript and programming as I go. I'm very much still at a beginner level - at the moment al I have is some actionscript for drawing rectangles and moving them about the screen. This is what I'm having trouble with at the moment: I have a class called 'Creature', and I want instances of it to interact with each other. I want them to do something when they come within a certain distance of another instance. And I want them to be able to pick a random other instance to get the location of, in order to do something with that information.
What I think I need is: A function for telling the distance between two (x,y) points.
A way of referencing the nearest other instance of the class. And a way of randomly selecting from all of the instances of the class.
