Flash :: Use HitTest Between BitmapData And An Object?
Aug 23, 2011
I have converted a PNG into a bitmap, then converted that into bitmapData.
I have a object called _player, and I wish to add collision detection, however I can seem to get it to work.
my code is:
if(bmd1.hitTest(new Point(_player.x, _player.y))){
trace("hit");
}
bmd1 is my bitmapData,_player is the object is wish to test against.
I am getting the following error:
1136: Incorrect number of arguments, Expected 3
I have looked around but cannott find what argument I am missing
I have tried
if(bmd1.hitTest(new Point(_player.x, _player.y), 50, _player)){
trace("hit");
}
I should mention that the reason for me taking this approach is that I have a PNG, with transparent areas, I need to test for collisions in the non-transparent areas, which is why I was using this approach
I have a PNG, i import that and convert to bitmap, then convert to bitmapData

how to use the bitmapData collision method. Now I'm trying to figure out if there is a way to see at what angle or coordinate of the bitmapData the collision happens? I need it in order to figure the accurate bounce angle after the collision occurs.

Im making a simple game with destructable terrain. Therefore i use a bitmap for the ground and a movieClip for the player. When the ground is a bitmap i cant use regular hitTestPoint because of the bitmaps transparent pixels. So i looking i the livedocs for the bitmapData.hitTest but i rly dont understand all the parameters.So my question is. How can i reproduce this with bitmapData.hitTest?
ActionScript Code:
if(ground.hitTestPoint(player.x, player.y, true)) {

import flash.display.BitmapData;
import flash.geom.Point;
//
var BitmapA:BitmapData = new BitmapData(550, 400, true, 0x00);
[code]....
This is using the bitmapdata.hittest way to check whether the one bitmap is overlapping the other. Throug pixel-to-pixel detection.But I'm having trouble understanding this line:
Code:
if (BitmapA.hitTest(destPoint, 255, BitmapB, currPoint, 255))
I know that destPoint is the topleft point from which it is determining all opaque pixels. No value is given to destPoint so basically it is checking from 0,0. Having determined all opaque pixels from that bitmap it should compare them with the opaque pixels of the other bitmap. But why does currPoint use the topleft coordinate of its movieclip? Couldn't it just as well use 0,0 too? I mean when determining the opaque pixels of bitmap two it might as well start checking for those from 0,0 as the topleft position as well?

Having used copyPixels to display an image, I'm trying to copy another in it's place when the mouse is hovering.The only way I can copy the new image over the old is by setting the If statement to == false. I know there's something wrong with testing the bitmapData of the loaded .png because the hitTest would apply to anything copied from that tile sheet... but how to designate just the copied area?

sometimes I get this extremely nasty bug:
Code:
ArgumentError: Error #2005: Parameter 0 is of the incorrect type. Should be type BitmapData.
at flash.display::BitmapData/hitTest()
This is the line where I get this error:
Code: if (player.bitmapData.hitTest(player.point, 255, tempUpgrade.bitmapData, tempUpgrade.point, 255))
I have absolutely no idea what went wrong. My object (tempUpgrade) is generated inside of a manager-class. There I can define the look of it and it gets cached. The image I use is a spritesheet (png) that's embed inside of my library-class. The spritesheet is splitted into appropriate pics via a CacheTileSheet-class.After that process they get thrown inside of an array because I need the bitmapData for pixel-perfect collision detection. Of course this is not the complete code so if someone needs more please let me know.

I have two png files. I import them using loaders. The images in the png files each have opaque (solid) and transparent parts. I want to use the bitmapdata.hittest method to detect when their opaque parts have collided.
[Code]...
I've been working on this for a couple of days now and nobody seems to know how to do this. Please don't post the examples on google, I've looked through at least the first five pages of results on google and haven't gotten any of them to work. The problem is that none of them provide an example of using this method with loaders, so I'm guessing the reason I can't get it to work is some gimmick associated with them.

I am working on an application where an image serves as cursor. Now i would like to know at any time over which object the cursor is hovering. Sort of like a HitTestObject(*) where i can then see what object the * represents. how i could accomplish this? (and using the mouse is not an option)

For days now I have been trying to get this hit test to work and which ever way I try it, it always comes back to the same result. I get a hit on the last item I pushed into my array but none on the previous items I pushed in. Also if I put a .sort() on the array it only gives a hit on the last item of the array, no matter which one I push in.
The idea is that I want to drag and drop objects onto the stage, they may not overlap so I need a hit test on the objects so I can make them undroppable when the hit test is true.
This is the part I have for dragging the objects to the stage, and adding them to arrays for the hit test.
Code:
private function onClickDragBuilding1ToGameField(e:MouseEvent):void{
building1Placeholder.x = mouseX-25;
building1Placeholder.y = mouseY-25;
[Code]...
Now if I run this I can add the object to the stage just fine no errors or other issues but the hit test only works on the last object I added to the stage/array and not the previous object I added to the stage/array.
Sso I drag the first object to the stage. (no other object are available yet so nothing happens, this is as it should be) Then I drag a second object to the stage, this reacts to the first object and returns the hit test as true. (Also great and working as it should.) Then I drag a 3th object to the stage, this reacts to the 2nd object I dragged just fine and return a true value, but it does not react to the 1 object I dragged onto the stage. Then when I drag a 4th object to the stage it will react to the 3th object I added, but not the 1st ad 2nd object.

I have a BitmapData object with an alpha channel. I'd like to know the fastet way to offset that alpha channel in ActionScript3 (FlashPlayer10). By offsetting I mean shifting all pixels of that channel in one direction (wrapping around the image borders) while leaving the color channels as they were.Is there a good way to apply a such a transform to one channel only?

In Flash, the BitmapData object can be used to store bitmaps in RAM, you can later draw them to a MovieClip using the beginBitmapFill() method.
How do you load an external bitmap file (.jpg) into a BitmapData object?

I'm cutting my teeth in actionscript 3 on a game that has a character running through a world. So, I have set up my Hit Testing by using the bitmap data hit test method, since I figured my world is going to be destructible - it'd be nice to update the level and then redraw it and have the character interact with the new change. (That works beautifully) I am however; a bit confused as to how I have my hit Testing set up. I've been messing around with it, and it works for now - but I'm not sure why.. currently, I have a character set up by using a class I built and using a series of animations I created. So, this character has a walking and falling animation, etc. This is a movie clip.
Then there's a bitmap 'emptyBitmap' with bitmap data created - however; I never really added this as a child to the character. This is sized to the dimensions of my character. My level is created as a movielip, then it's drawn to a bitmap - when the level movieclip is changed, the bitmap redraws, and that's how this updates.

Using Actionscript 3 is there a way to search one bitmap for the coordinates matching pixels of another bitmap?
[URL]
Somehow you would have to loop through the bigger bitmap to find and the the pixel range that matches and return those coordinates. For example the Bitmap with the "E" is 250 pixels over and 14 pixels down in the bigger bitmap.

The title might be a little misleading. Look at my code and I will explain
public static function loadTile(tileDir:String = "empty"):void
{
if(tileDir != "empty")
{
tPoint = new Point(0,0);
tRect = new Rectangle(0,0,30,30);
[Code]...
I am trying to do tiling with sprites. I want my tiles to be interactive, so that is why I am using the sprite object instead of using regular bitMaps to represent my tiles. You might be wondering why I wouldnt just use graphics.beginBitmapFill(tImage); and graphics.drawRect(0, 0,tWidth ,tHeight ); to pick out the tiles I want to use. Well reason being is because it turns out that drawRect() first and second parameters actually alter the location of where the actual sprite sits at.
So if I set the x and y properties of the sprite to x = 20, and y = 20. then I set my drawRect(20,20). it actually adds an extra 20 pixels to my x and y coords of my sprite. And I know the reason why, I just need to know a better way.

I'm trying to trace the path of an object by using setPixel on the object's position every frame in a BitmapData/Bitmap pairing. These pixels aren't showing up normally and I suspect I have a fundamental misunderstanding of the BitmapData class. Here's what I'm doing:
public var contrailBase:BitmapData;
public var contrail:Bitmap;
private var contrailColor:uint;[code].....
Using this code, the red pixels don't show up. If I initialize contrailBase to 0xFF000000 instead then I get a black screen on which the red pixels DO draw, but I need the bitmap to be transparent except for the contrail. What am I doing wrong?

I have a function that checks if 2 objects are touching OB1 and OB2, if they do touch it runs the rest of the collision code where OB1 is the character and OB2 is a tile that the player cannot pass through.
I came across an issue where i wanted sprites to be separate from the hitboxes but my collision code works by checking the height and width of an object (you guys know the drill).
So i have a Tile class with 2 parts to it, a bitmap and a movieClip.
So i have this setup(pseudocode):
Code:
loop
{
function collision (ob1 , ob2[loop].movieclip)
}
This should work right? But it ONLY works for the first object in the loop!

btw, first I used assigned thumbContainer as the mc argument (outside the loadThumbs() function) and it worked but not exactly what I wanted... because I thought it is supposed to update when the movieclip is animated but it actually didn't... when I use a scroller, only the thumbs that are first loaded to the stage get the reflection..

I would like to know if there's the way to do collision check on every object on the stage,
[Code]...
I want to make the object such that it falls on a rotated platform and land according to it's angle. I've success fully make it landed according to it's angle before it lands. but the problem here is that, after the landing when I trigger the rotating platform, the object falls when the platform is out of it's hit area. Is there a way such that it will work like a car wiper and wipe the object towards it's direction?

I'm coding a really simple 2D platforming game in Flash using AS3. I'd like to define two different types of terrain surfaces that the player can walk on based on classic platforming elements. Type1: the player can walk on, and if the player jumps, they will hit their head on it and bounce back to the ground. Type2: the player can also walk on, but if the player jumps and hits their head, they will simply pass through the surface and not bounce back to the ground.
I am using hitTestPoint to resolve collisions for this. My question is: What would be the best method to test for what TYPE of ground I am colliding with? Each ground type has it's own Class associated with it in my Flash IDE and all the different terrain surface types are in the same movie clip on the stage.
Currently I'm testing to see if it hit one type of ground surface, then i'm testing if it hit the other, and then based on those results, I process what I want to happen. This seems to work okay right now, but I'm imagining that I may want to create more than 2 types of ground to collide with. For example, moving platforms. It seems like the code will start to get complex
Eg.
if(_groundType1.hitTestPoint(_player.x, _player.y, true))
{
if(_groundType2.hitTestPoint(_player.x, _player.y, true))

My first post in Actionscript.org. but I'm a long time visitor / fan. I'm moving a object with mouse but using some easing values. means it will follow the mouse slower.
Here is the file.[URL].. How can i check hitTest in this situation. even if i do it normally...the object is passing the collision object simply before stopping..because its being moved with mouse..
