java - Using libgdx, how do I reset a PerspectiveCamera without resetting the view so I can correctly rotate the correct axis? -


I am using libgdx. I'm going through the basics so that I just display a box using the following perspective cameras to display a set of latitude and one box: 

  environment = new environment (); Cam = new perspective camera (67, gdx graphics .getWidth (), gdx. Graphics.getHeight ()); Cam.position.set (10f, 10f, 10f); Cam.lookAt (0, 0, 0); Cam.near = 0.1f; Cam.far = 300f; Cam.update (); Zirokam = New Perspective Camera (67, Gdx graphics .getWidth), Gdx Graphics. GateHight ()); Zerokam. Refinement.Set (10f, 10f, 10f); Zerocam.loket (0, 0, 0); Zerocam.near = 0.1f; Zerokam.far = 300f; Zerocam.update (); I can rotate the box without moving the box using

:

This is in my renderer class: 

  ModelBatch.begin (zerocam); ModelBatch.render (drawAxis (0), environment); ModelBatch.render (drawAxis (1), environment); ModelBatch.render (drawAxis (2), environment); ModelBatch.end (); ModelBatch.begin (cam); ModelBatch.render (DrawBox (), environment); ModelBatch.end (); Cam.update ();

This is in my screenclass: 

  Gdx.input.setInputProcessor (new camera input controller);

As you can see that this will rotate the cam perspective camera and if the zerocam is not a perceptive camera, the box will rotate again but the axis is constant The problem is that if I have pulled the box, the box is spreading on one side, dragging left / right will still rotate like a clock and will not have a diamond-round-goal. Hope this makes sense.

How can I use the following code in the public class screenclass, the input processor to rotate the box properly. 

  Touch dragged (int screen number, int screenwise, pointer pointer)

Basically when I pull left or right, I rotate the box left / right I would like to see what really is happening on cam.

I am heading towards this direction: RotateBox (int x, int y) in RenderClass to my ScreenClass Calculate how much will rotate. 

  Public Zero Rotatebox (int x, int y) {Vector3 difvector = cam.position.sub (zerocam.position); Cam.rotateAround (new vector 3 (0f, 0f, 0f), difveector, 1f); }

This just gives me the difference of cam to zerocam , but I think this is the right direction. I think I use the X and Y values ​​to calculate the direction to rotate in some direction, and then somehow find the float value to apply a specific axis.

Thanks

c# - Reactive Extensions ControlScheduler -

Well, I'm using Reactive Extension Event Handler to handle my app events, I run the headlines on the Yuri thread. I also use ControlSubular for However, recently I am getting cross thread exception despite using control scheduler and I do not know what the problem is. Code: Observable.FromEventPattern & Lt; String & gt; (CC, "UiAlertMessage", New Control Session ()) Subscribe (_ = & gt; {Alert Control. (Show this language, title, _.EventArgs.UppercaseFirst ());}); The new control scheduler (this) is not to run the code on the UI control thread, so I do not get cross threading exceptions? you should do Observable.FromEventPattern & lt; String & gt; (CC, "UiAlertMessage"). AboveOption (this). Subscribe (_ = & gt; {Alert Control. (Show this language, Titles, _.EventArgs.UppercaseFirst ());}); This is the standard way of sending a scheduler related to specific controls. Passing control scheduler as you have got subsc...

ios - How to determine if NSLayoutConstraint is horizontal or vertical? -

It seems that this should be a simple task, but if a NSLayoutConstraint is a horizontal or vertical The obstacle? The only way to try to make this difference is by [constraint description]; Calling and then the resulting string "V:" or "H:" I want to find this information, because of I have around 2 similar restrictions which are prototype storyboard UITableViewCell , the only difference is that supervision is horizontal Describes the distance, and the second vertical. Any suggestion would be very helpful! Edit: I accepted the reply of Grimozoar because its interpretation is a great answer and the way I am working to parse the details, @ kongtomorrow I also want to give credit, answered me here! Thanks for the help! Here is the real code that I used to find the hindrance: NSArray * constraints = [bubble constraints]; (If ([[obstacle first item]], then e-mail: message labels] and [[barrier is second int.] Is aqual: bubble] and amp; a...
