c++ - move obstacles randomly in game scene in cocos2d-x -


I am creating a game in Xcode using the cocos2d-x (c ++) game engine, and I Starting a game in the game I tried to move obstacles randomly in this game, but it is progressing in sequential order, please solve me the following code I used to move the barrier 

  obs1 = CCSprite :: create ("branch.png"); Int val = arc4random% 7; obs1-> setPosition (ccp (winwsize / val, winhsize / 8)); This- & gt; Add Chald (Obs 1, -1); obs1-> SetVisible (true); Schedule (schedule_selector (SceneThree :: OnUpdateFrame)); Zero GameScene :: OnUpdateFrame3 (Boat deltaTime3) {if (obs1-> getPosition () x & lt; -. (Winwsize / 2)). {obs1-> SetPosition (ccp (obs1-> getPosition () x + (2 * winwsize), obs1-> getPosition () y)). } Obs1-> SetPosition (ccp (obs1-> getPosition () x17, obs1-> getposition () wi).); }   
 
 
 First of all, you are only using a random value for the initial position Are there. And on every tick (this is an update function), you just want to reduce 17 by x position, which can result in gradual steps.  
 In addition, how your random number is generated, value 0-6, so you will get a value like "winWsize / (a ​​number from 0-6)", as a result, or if not Value IMO will be limited (compared to full screen)  
 Why not make sure that you use this (arc4random ()% winWSize) in your "OnUpdateFrame3" function, so make sure that This is something like arc4random ()% winWSize (this will give value 0-winWSize)?  
 Try every tick to get a new random position   zero GameScene :: OnUpdateFrame3 (float deltaTime3) {float xValue = arc4random ()% winWSize; obs1-> SetPosition (ccp (Xvalue, obs1-> getPosition () wi).); }   
 But it is only moving forward with X axis, u can also use similar technology as Y axis too. Also, arc4random can not work on Android, so you should also see it,  
  
 Or, you can also use "timestamp" to make your own random value Are there. This is your choice.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
