ActionScript 3.0 :: Unable To Use Tile Sheet For Blitting?
Feb 20, 2012
I am trying to get bitmapdata from a loader to be able to use my tile sheet for blitting. I seem to be unable to get it to work. After some testing I noticed that none of the code after this piece is executed in the SWF, so apparently it always freezes at this point:
ActionScript Code:
tileSheet = (evt.target.content as Bitmap).bitmapData;
bmp = new Bitmap(tileSheet);
addChild(bmp);
Obviously I am doing something wrong.
I'm making a game where you place tiles on a grid. When placing a tile, I need to check the existance of another tile to the left, right, or above and below, otherwise the tile should not be placed.. Here is a function I thought would work, that accepts one variable (the position of the tile just as it is about to be placed) :-
private function checkSurroundingTiles(gridPosition:uint) { var t1 = gridPosition - 12; var t2 = gridPosition - 1; var t3 = gridPosition + 1; var t4 = gridPosition + 12; for(i = 0; i < gridRefArray.length; i++) { var checkTile = gridRefArray[i]; if(checkTile == t1) { return true;
I am a bit new to using blitting for graphics. But I have worked up a few demos myself, and I have been reading a lot of information on the methods used. One common theme I have been seeing though is that all of them brute force rendering; drawing the farthest back object first and stepping through all other objects. even drawing objects that are going to be completely overlapped. The reason all of them say this is that any kind of testing to see what should be drawn actually takes more time than just drawing everything with no checks. Is there any kind of way to detect what should be drawn, that will run faster than just drawing everything?
I'm using a blitting engine that uses bitmapData. No display objects.Is there a fast pixel perfect collision detection available for such a game system?I already tried CDK but that didn't work because it assumes you have display objects which my objects don't use. Sometimes my objects are pretty big and hitTest sucks in this case. I already tried circle-to-circle collisions but that didn't do the trick either.
What do you think about mixing this two up? Would it lead to better performance for the scenario described below?However, method done below still contains jerking/stuttering in animationWhat my app does is to create a random mix of smiley and draw it into the canvas, and update the movement of the smiley (x,y)I have a source bitmapdata containing different smileys each of the same size.Example:The app creates a random mixture of smileys inrandom length;Example:tc...I have 2 vector that acts as pool. 1 vector is to store bitmapdata1 vector to store SmileyObject (SmileyObject has 3 properties, positionX, positionY,bitmapData)If the pools is empty, I create a new bitmapdata and SmileyObjectThe bitmapdata copypixels random smileys from the source bitmapdata.This is then placed into SmileyObject.I have a loop that goes through each smiley objectand copypixel each bitmapdata into the canvas along with the x,y position.However, even with copypixel and pooling bitmapdata + smiley object,I can still view the stutter / jerk / stuttering / jerking in the smiley animation.
I know there are different situations where one would be better than the other, but I'm comortable with a generalized statistic of... How much faster is blitting than using vector Sprite objects in Flash?
I have been working on a map viewer based blitting technique. As part of the map I need to draw approximately 50000 lines and performance is currently really poor.
I'm not sure what I'm doing wrong for this simple task. I have a sheet and right now I only want to use a small portion of the sheet. I try to click on the sheet and it moves around. I lock it, and I can't select any part of it. How do I separate it?
BTW does it matter if it's a symbol or just a PNG sheet?
I would like to know how much it would cost to create sheet input in flash like in this site [URL]..what knowledge do I need to have, to create it on my own.
I haven't worked with flash yet, that's bad, but language itself is not problem for me. The methods I need to know is the problem for this. My goal is so that user can input notes with his keyboard, and after he presses button in page, I get inputed string as letters, not as notes.
I am developing a small application, where the user can change the color of a box from a radio button(a-red or b-green). as soon as he changes the color, the respective color value(0xFF0000 or 0x5CBC32) should be updated in an xml sheet which is kept in a server.
i would prefer asp because the xml file will be placed in a windows server.
xml sheet:
<?xml version="1.0" encoding="iso-8859-1"?> <colors> <boxes> <box1>"here only i want to udpate the color value chosen by the user"</box1> </boxes> </colors>
How can I view CSS style sheet on a website online? I know how to view the html source code, but how can I see the Css style sheet without knowing the name of the file? I'm asking because I'm taking classes in css and I want to learn how people make things with css. [URL]
SO I am working on animating a 20/fps sprite (an SCV from Starcraft 2). The animation is 1 second long, and thus 20 frames. I have made a sprite sheet in photoshop, and have each frame as a separate layer. I import the PSD into my library and have it convert the layers to "Flash Frames". I get each frame nicely tucked away as a layer in my library. Problem is, it gives an ugly white border (about 1 to 2 pixles thick) around my sprites, making it look like I did a terrible crop job. However, the crop job is fine (I can change the background in the PSD to black, and the cropped sprite frames look perfect! What have I done wrong or need to do?
I have a contact sheet that I was told to place into an external .swf and then to place a contain in the timeline of the website where I want the contact to show up and then to call up.

I am pulling a blog into flash through an XML sheet. I have a clip in the library that gets attached per blog entry. The issue I am having right now is not all the posts are the same length so I am trying to adjust the clips background to the height of the post text box, but they are all reading as the same height so they aren't properly adjusting. I even have the text boxes set to autoSize = true;
Here is my code..the resizeBlog function is where I am trying to resize it and then I want to adjust its y property accordingly.
I need to figure out how to print out 2 different objects on a separate sheet of paper with only 1 print button, a PRINT ALL button.Here is what I thought would work but not working, please help:
I'm making a vertical scroller with a mask. The content is inside a movieclip and the user scrolls around it.My problem is, I have lots and lots of content to put inside that movieclip, and I've reached the limit of the sheet. All inside the movieclip. How do I resize the sheet/canvas inside the movieclip so that I can put more info in it??I've googled it, but found nothing.Note: I just want to change the size of the sheet/canvas inside a movieclip and I don't want to change my document size. I'm using flash CS3, AS2.
In Flash I am able to create a font asset and add it to the library:I want to convert this asset into some BitmapData that will contain all of the characters with the correct letter spacing/line height etc.
Is there an inbuilt way of doing this other than manually creating text fields, adding a character, using BitmapData.draw() and then adding the result to a sprite sheet?
If I need to do it manually like above, is there a way to retrieve all of the embedded characters? For example, in the above screenshot I'd expect only a-z, A-Z. Or will I need to note these manually as well?
I have a small doubt in flash cs3/cs4. can some one tell me, is ther any way to read EXCEL values from flash cs3/flash cs4. I want to read values from excel and to display from flash side.
I'm trying to generate an animation containing all the frames from a sprite sheet. Then also append them again but flipped vertically. I have an animation class to create the animation, the stuff I wrote just gets the image from the sprite sheet and sends it to this class. But "frame.scaleX = -frame.scaleX;" isn't changing anything, neither is "frame.scaleX = -1;". It's just leaving the bitmap the same..

I've found a million tutorials on doing this by loading a CSS file, which is fine, but I don't want to load CSS...I'd rather just modify the thing with actionscript. I've done this before with one of my files, but can't seem to find it.
I am attempting to build a tool which creates a graph through data drawn from a MySQL database, however the .swf doesn't seem to accept the xml sheet that is created by the PHP. I was wondering if anyone had any thoughts on this?
So as far as I can tell list-style-image (or any list-style at that) is not one of the available css properties enabled with a TextField.I want to have a list of items with bullets in front of them, but using a custom png image for the bullet.
Im trying to make a menu with xml dynamic text with a style sheet (so i can change the font, colour, size e.t.c. via css) that reeds from the xml file and places the correct amount of buttons on stage based on the xml nodes. Here is a fla that ive been working on.

I installed Adobe Flash CS5.5 a couple of days back...Trying to learn a few basic tricks such as motion tween (messed up things with the bone tool though)..Well the problem is, a friend of mine made a 3D drawing in Solid Works(a modelling software). It is a sort of box, now he wants me to make a flash animation for the box which starts from a sheet of paper and folds into a box and then the camera zooms out.
Now i have no idea how to do that..jpg file can be made and imported to flash...but as it will be an imported file how can it be manipulated to achieve the final task....taking screen shots of the box at various stages of solid works can be done and then played all together in flash baut it would be very tiresome and time consuming... I dont want anyone to make it for me just guide me what tools and tutorials to look at.
