move

问题 var server = message.guild; for (var i = 0; i < server.channels.array().length; i++) { server.channels.array()[i].delete(); } server.createChannel("Text Channels", "category"); server.createChannel('general', "text"); I am trying to make the text channel 'general` go into the category 'Text Channels' All the solutions I have found rely on you knowing the categories id . I was wondering if there is a way I could get the category id , or else move general into "Text Channels" simply by its name

问题 I'm currently writing a game project as for the game "4 in a row". To make the animation where the picture widget disk falls in the column, I've been thinking about creating a while loop for as in: while widgetx != __ and widgety != __ where at the blank parts there will be the values I'll need to get. My question is if there's a function that returns the current x and y value for a widget. 回答1: winfo_rootx() and winfo_rooty() return the coordinates relative to the screen's upper left corner.

问题 This question already has answers here : Pygame doesn't let me use float for rect.move, but I need it (2 answers) Closed 7 days ago . When i move right using the right key, i accelerate to a max speed. When i release it, i do decelerate to a stop so that is fine. However, when moving left using the left key, and after releasing it, i continue moving at a fixed speed and then come to an abrupt stop after a short while. Any idea what could be wrong with my code? The original code is from http:/

问题 As std::move(v) is merely a cast like static_cast<T&&>(v) where T is the type of v . But why the moved variable not a reference of the original object? For example, when o1 is "moved" to o2 , why can't we access the str_ of o2 through o1.str_ any more? #include <string> #include <iostream> struct MyClass { std::string str_; MyClass(MyClass const &) = delete; MyClass &operator=(MyClass const &) = delete; MyClass(MyClass &&o) : str_(std::move(o.str_)) {} MyClass(std::string const &str) : str_

问题 I am thinking a strange use case where I want to move an object to a nullptr. Maybe I should give an code fragment: class Objpair { public: Objpair(Obj&& a, Obj&&b) : first(&a), second(&b) { } private: Obj* first; Obj* second; }; The problem is that when a and b is out of scope, the first and second pointer will be dangling. If I can move Object a onto the first pointer then there should be no problem of double free and scoping issues. If the member first were declared as Obj not Obj* pointer
