  Haxeflixel has a lot of really nice helper functions for things like this.
  https://api.haxeflixel.com/flixel/math/FlxVelocity.html#velocityFromAngle

  import flixel.math.FlxVelocity;
  ...
  var angle = 90;
  var speed = 1500;
  bullet.velocity = FlxVelocity.velocityFromAngle(angle, 1500);

  Why does my sprite loop keeps blinking every time loops

  @ttt said in Why does my sprite loop keeps blinking every time loops:

  loadGraphic(AssetPaths.player__png, true, 16, 16);
  setFacingFlip(FlxObject.LEFT, false, false);
  setFacingFlip(FlxObject.RIGHT, true, false);
  animation.add("d", [0, 1, 0, 2], 6, true);
  animation.play("d");

  Can you post the image you're using? It sounds like there's a problem with how you locate the frames of your sprite sheet.

  If you make it a 48x16 strip with each frame being 16x16, it should work. Like so:
  |0|1|2|

  Or, if you make the image 32x32 like this it should work too
  |0|1|
  |2| |
  where frame 3 is a blank area.

  If you have a blank area in your image it will show nothing for that frame of the animation and blink.
  |0|1|
  | |3|
  So, in this case frame 2 is a blank area and will show nothing when animation frame 2 is drawn.

  @dean

  Thanks for the reply. I am using the Tiled map editor.
  I will do a bit more research and look at some of the demos a bit more.

  I had the same problem. My solution was to install Visual Studio 2017 at the default location. C:\Program Files (x86)\Microsoft Visual Studio
  As far as I understand it with Version 2017 Microsoft removed the PATH Variable that points to the location of Visual Studio. There was a fix to HXCPP but I think this needs Visual Studio to be installed at the default location

  My code will work but you have to copy all your pixels to a Bitmap object's bitmapData property. I neglected to implement that part of my Flash project in my OpenFL project.

  @blaise_rascal Yes, what he meant is that for loops are not allowed after a class name / directly in the class body. They must be inside a function.

  I've managed to devise a workaround for this problem. It involves loading a 1x1 pixel FlxSprite, resizing it that based on the line dimensions and then stamping in on to graphic.

  Based on this post here, there may be a performance increase on mobile in using this approach.

  Okay. I think it's time to call it. The same thing happens with each suggestion I try. So I dunno what the problem is. I'll probably come back to this project again eventually, but I think I'm done being frustrated for a while.

  Thanks for all your help @galoyo, I appreciate it!

  Seems my problem is partially a little bug with the current release version of OpenFL:
  http://community.openfl.org/t/sampling-second-texture-in-glsl-shader/10628

  Using the GIT develop version allows it to work on flixel sprites.
  But, I can't get a shader that samples a second texture to work in the FlxCamera's shaders.

  you can scroll text or display anything you want in the region. if I remember correctly, the scrollbars will be hidden unless there is something else to show. you can have the window any size and display objects anywhere on the screen.

  [Solved] Game plays sound once and then cannot find file

  (First of all, as a side note: I'm an idiot that didn't realize the "my sound playing one time" was actually the bleep the debugger makes when it throws up an error...woops.)

  I looked at your README, @galoyo, and that actually completely solved my problem. I hadn't found mention about setting the asset paths in the Project.xml until now and yours was quite enlightening, and actually makes sense why my sound wasn't playing and the error it was throwing in the debugger!

  To be more explicit for the sake of including everything here for posterity, I had to define my sounds in Project.xml like so:

  <assets path="assets" if="flash" exclude="*.ogg" /> <assets path="assets" if="windows" exclude="*.mp3" embed="true" /> <assets path="assets" if="neko" exclude="*.mp3" embed="true" /> <assets path="assets" if="linux" exclude="*.mp3" embed="true" /> <assets path="assets" if="html5" exclude="*.mp3" embed="true" /> <assets path="assets/sounds" rename="sounds" if="flash" embed="true"> <sound path="mySound.mp3" id="mySound" /> <sound path="myOtherSound.mp3" id="mySound2" /> </assets> <assets path="assets/sounds" rename="sounds" unless="flash" embed="true"> <sound path="mySound.ogg" id="mySound" /> <sound path="myOtherSound.ogg" id="myOtherSound" /> </assets>

  Then, I called the sounds in my code like so:

  FlxG.sound.play("mySound", 1, false); FlxG.sound.play("myOtherSound", 1, false);

  And that's all there is to it! Since I'm on Linux, I could simply use ffmpeg to convert my original sound files, such as wav files, to the appropriate mp3 and ogg formats like so:

  ffmpeg -i mySound.wav mySound.mp3 ffmpeg -i mySound.wav mySound.ogg

  Thanks again to both of you for helping me!

  @ttt

  i saw visual c++ but i didn't see c++ win32

  I think that should do it. Like I said, I missed that step.

  In case you, or anyone else didn't install C++ while installing Visual Studio, like me, you can install it after the fact.

  This link is where I found how to install C++ after the fact. https://stackoverflow.com/questions/31953769/visual-studio-doesnt-have-cl-exe

  I used this method from the comments of the chosen answer on that thread.

  "if Visual Studio is already installed, choose File | New | Project | C++ and you will be prompted to install the necessary components." – jodis

  But you can also do this I reckon.

  You don't need to re-download the installer for Visual Studio: just go to Add or remove programs -> Visual studio community 2015 -> modify. From there, I clicked languages, Visual C++. Added cl.exe! – user2831602

  @ttt

  Where ever you add your background image you can size it there.

  var bg = new FlxSprite(); bg.loadGraphic("assets/images/bg.png"); bg.setGraphicSize(FlxG.width, FlxG.height); bg.updateHitbox(); bg.scrollFactor.set(); add(bg);

  The scale mode demo is for the entire game, in case you want to make it stretch to fill the whole screen.
  In that case, you can do it in Main.hx:

  import flixel.FlxG; import flixel.system.scaleModes.FillScaleMode; // add this in new() { } FlxG.scaleMode = new FillScaleMode();

  @mobandon Ah, I see. That's probably because OpenFL's API docs are based on the ActionScript 3 / Flash API, where MP3 was the only supported audio format I think.
