c++ - OpenGL 3.2 2D rendering issues -

-

I accept that I am not a graphics programmer first, so please with me Be bare) For some unusual reasons, when I make two phantom batches and attempt to draw only one frame of my screen (or around) halfway in half, "Lost"; This little campfire happens regardless of the position of the Sprite.

When rendering wireframe modes are the same results, it does not appear that a large black polygon is being prepared and overloaded under tilemap laying.

This is the code used to start OpenGL: 

  GlobalGone Mod (GL_fron_backback, GL_Fill); GlEnableClientState (GL_VERTEX_ARRAY); GlActiveTexture (GL_TEXTURE1); GlActiveTexture (GL_TEXTURE0); Gloditrange (0.0 f, 1.0f); GlEnable (GL_DEPTH_TEST); GlDisable (GL_CULL_FACE); GlEnable (GL_TEXTURE_2D); GlDisable (GL_LIGHTING); GlDepthFunc (GL_LEQUAL); GlDisable (GL_DITHER); GlClearDepth (1.0f); GlEnable (GL_CW); GlEnable (GL_BLEND); Globefenk (GLICCR_ALPHA, GL_ONMINUSISUSRCCLAAPHA);   
 I uploaded the relevant code here:  
 SDL2 is used for window construction and context management, although I do not use anything else with SDL .  
 Any thoughts?  
 Thank you!   
 
 
 The problem was solved, after unloading the array / alarm buffers after calling GlDrawElements No.  
 It was to be kept after glDrawElements:  
  glBindVertexArray (0); Glubbind Buffer (GL_ARRAY_BUFFER, 0); Glubbind Buffer (GL_ELEMENT_ARRAY_BUFFER, 0);

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...
