android - Get DebugDraw working in JBox2D -

-

I try to run DebugDraw in a simple Android JBox2D project.

I just expand DebugDraw are this way and put some log output: 

  public class extends SimpleDebugView debug Drav {private static final String TAG = "SimpleDebugView "; Public SimpleDebugView () {Super (New OBBViewportTransform ()); } @ Override Public Wide Daipoint (VAC 2 Arjipiint Float Ajiaradiaonskrin, color 3 F Arjerolr) {Logkai (tag, "Draw Point"); } [@Override public void drawSolidPolygon (Vec2] corner, integer vertexCount, Color3f color) {Log.i (TAG, "solid polygon Draw"); } @ Override Public Wide Draw Verbal (VAC2 Center, Float Radius, Color 3F Color) {Log. I (tag, "draw circle"); } @ Override Public Blank Draw Associated Carrel (VAC2 Center, Float Radius, VAC 2 axis, Color 3F Color) {Log. (Tag, "Draw a solid circle"); } @ Override public spaces draw segment (VAC 2 P 1, VAC 2 P 2, Color 3 F color) {Logkai (tag "segment highlighted"); } @ Override Public Wide DrawResform (XF Conversion) {Log. I (tag, "draw transform form"); } @ Override Public Zero Drawing (float x, float y, string s, color 3f color) {Log.i (tag, "string draw"); }}   
 I use the new debug class like this:  
  [...] mWorld = New World (gravity); MWorld.setAllowSleep (true); SimpleDebugView Simple DebugDown = New LiveDebug View (); Simpledbugdravksetflags (Debgdravki_spbit | DebugDrawki_abbbit | DebugDrawki_parbit | DebugDrawki_senterofmssbit | DebugDrawki_jointbit | DebugDrawki_dinmictribit); MWorld.setDebugDraw (simpleDebugDraw); [...]   
 After this I can make body and start physics simulation.  
 My simulation works, I render my stuff on a canvas based on simulation.  
 But when I want to use the debug Drav am (because it sometimes makes it easier to debug the modeling of the physical world), do not see the log output, it does not seem to work And even when debugging, breakpoint does not get hit in my SimpleViewviewview. So it seems that the methods are not called at all. Am I using the debug draws wrong?   
 
 
 I got the solution.  
 I have to tell my physical world that it should attract the debug through:  
  mWorld.drawDebugData ();   
 Then I step straight (after doing this it is called and my methods are called.  
 In some way I thought it would be done automatically When I give a DebugDraw, but it was not.

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

c# - Textbox not clickable but editable -

-
I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
