The phaser game not starting error on
import Game1 from "phaser/src/core/Game";
import { Game } from "phaser";
console.log(Game1, Game);
const app = new Game1(gameSettings);
the following output of the console log which are similar class:
but when I trie to make use the one from the phaser js directly, no error found
import { Game } from "phaser";
const app = new Game(gameSettings);
Thanks in advance for answers which part I do wrong.
In all example I found on the web I see this kind of imports for Phaser
import 'phaser';
import Phaser from 'phaser';
import * as Phaser from 'phaser';
and then boot the game with
new Phaser.Game(config)

I'm trying to use the D3 extension in a Nuxt 3 project and for that I created a d3.client.js file in the plugins/ directory.
import * as d3 from "d3";
import { defineNuxtPlugin } from '#app'
export default defineNuxtPlugin(nuxtApp => {
nuxtApp.vueApp.use(d3)
})
However, when I try to use it gives me a 500 Internal Server Error document is not defined.
<script>
import * as d3 from "d3";
export default {
name: "globe",
created() {
d3.select("#globe");
}
}
</script>
How can I solve this?
d3.select() uses document.querySelector() under the hood. Since you're working server side, you don't have access to document yet. So you'll need to mock it or to avoid using it.
You can avoid using it all together by passing an element instead of a string to d3.select(), as it will then create a functioning d3 selection without running document.querySelector(). And since every other chained .select() or .selectAll() uses previousSelection.querySelector(), you can just continue from there.
If you do not have access to the DOM element directly, you might want to mock document. This article suggests using JSDOM:
import { JSDOM } from 'jsdom';
// create a new JSDOM instance for d3-selection to use
const document = new JSDOM().window.document;
d3.select(document.body)
.append('div');
I managed to solve it by using the d3.select with a Vue reference.
const globe = d3.select(this.$refs.globe)
I am trying to reuse karate scripts and perform load testing using gatling. The scenario defined is to load constant 50 users per second for 10 seconds. (To load test 500 users) However the number of requests per second does not exceed 20 requests per second in the gatling report. Please let me know if i am doing anything wrong.
ExampleTest.java code which executes Karate scripts
//package examples;
import com.intuit.karate.Results;

//System.setProperty("karate.env", "demo"); // ensure reset if other tests (e.g. mock) had set env in CI
Results results = Runner.path("classpath:examples").tags("~#ignore").parallel(10);
generateReport(results.getReportDir());

jsonFiles.forEach(file -> jsonPaths.add(file.getAbsolutePath()));
Configuration config = new Configuration(new File("target"), "demo");
ReportBuilder reportBuilder = new ReportBuilder(jsonPaths, config);
reportBuilder.generateReports();
}
}
Scala Code to define load test scenarios.

}
We updated the docs (in the develop branch) with tips on how to increase the thread-pool size if needed: https://github.com/intuit/karate/tree/develop/karate-gatling#increasing-thread-pool-size
Add a file called gatling-akka.conf to the root of the classpath (typically src/test/resources). Here is an example:
akka {
actor {
default-dispatcher {
type = Dispatcher
executor = "thread-pool-executor"
thread-pool-executor {
fixed-pool-size = 100
}
throughput = 1
}
}
}
Since we made some fixes recently, please try to build from source if the above does not work for 0.9.6.RC4, it is easy, here are the instructions: https://github.com/intuit/karate/wiki/Developer-Guide
If that does not work, it is important that you follow this process so that we can replicate: https://github.com/intuit/karate/wiki/How-to-Submit-an-Issue
Please see these links below for good examples of how others have worked with the Karate project team to replicate issues so that they can be fixed:

I am making a game engine in haxe/openfl. so far it's just supposed to display the image that belongs to the thing object. what I have built so far runs perfectly on when deployed as a flash application, but closes instantly when I deploy it as a windows application. It just creates a blank screen in html5. I have not tested other targets. I am using HIDE, and every time it crashes, HIDE brings up the message: "File c:\Users\Adu\Documents\HaxeProjects\Downloaded\Export\windows\cpp\bin\Downloaded.exe was changed. Reload?" and gives me the options yes or no. My answer doesn't seem to change the situation. when I manually go into the export directory and run the application, it gives the error: "Error Custom([file_write,stderr]). Here is my code:

why is it that it works on flash but not windows? How do I fix this?
First off - this doesn't work fine on flash either. Are you running this in the flash debug player? If you don't, which I assume is the case, you won't see any exceptions.
There's a null reference error at this line:
objectManager.objects[zOrder].push(this);// this adds it to the list of objects
You are accessing the array at index zOrder, which doesn't exist. objects is being initialized to [], which does not include the "inner arrays" (it can't, really, how would it know how many of them there should be?).
Now, Windows builds don't give you very helpful debug information by default. A simple way around is to use neko (which mostly behaves the same as hxcpp builds, except it compiles faster and performs worse) for debugging, where you get a stacktrace by default on crashes.
Sure enough, it's the same issue as in flash, the only difference is that native builds crash while flash just "ignores it" and tries to carry on.

I'm a beginner of both gtk and GtkD.
Now, I'm trying to get input from keyboard with reference to this .
But, It seems that three years have made some changes in Toolkits.
I wrote code below. However, I got strange values of ev in callback function.
I could not see any prospect of resolution with going alone.
So, could you show me where to modify?
I appreciate you in advance, and also your patient with my poor English.
I'm using gtkD-2.1.1 and gtk+3.2.3.
this is the full code:
import std.stdio;
import gtkc.gdktypes;
import gtk.MainWindow;
import gtk.Widget;
import gdk.Event;
import gtk.Main;
class Window : MainWindow{
immutable width = 200;
immutable height = 200;
this(){
super("input test");
setDefaultSize(width,height);
setEvents(EventMask.KEY_PRESS_MASK); // Actually I don't know how this works
auto callback_func = cast(bool delegate(Event,Widget))&get_key; // I doubt this cast
this.addOnKeyPress(callback_func);
showAll();
}
bool get_key(GdkEventKey* ev, Widget widget){
writefln("sender %s", widget);
writefln("type %x",ev.type);
writefln("window* %x",ev.window);
writefln("send_event %x",ev.sendEvent);
writefln("time %x",ev.time);
writefln("state %x",ev.state);
writefln("keyval %x",ev.keyval);
writefln("length %x",ev.length);
writefln("gchar* %x",ev.string);
writefln("hardware_keycode %x",ev.hardwareKeycode);
writefln("group %x",ev.group);
writefln("is_modifier %x\n",ev.bitfield0);
return true;
}
}
void main(string[] args){
Main.init(args);
auto win = new Window();
Main.run();
}
Yes, that cast is wrong. I guess that Signature with GdkEventKey* is outdated. Change your get_key to take an Event and you should get proper results:
...
auto call = &get_key;
...
bool get_key(Event e, Widget widget){
GdkEventKey* ev = e.key();
...
I have never done anything with GtkD, and this is just the result of some glances over the docs. So, it's probably not best practice, but it should get you back on the road.
I'm working on a Dart project where I have created a custom element with the Web_ui package that has some animation. What I was hoping to do is to have within the dart code for the element something like this....
class MyElement extends WebComponent {
...
void StartAnimation() { ... }
...
}
and then in the main() function of the dart app itself I have something like this...
void main() {
MyElement elm = new MyElement();
elm.StartAnimation(); // Kicks off the animation
}
The Dart editor tells me that Directly constructing a web component is not currently supported. It then says to use WebComponent.forElement -- but I'm not clear on how to use that to achieve my goal.
While you can't yet import web components into a Dart file, you can access them via query() and .xtag. xtag gives you a reference the web component instance that the element is associated with. You do have to be careful that you allow the Web UI setup to complete so that xtag is given a value.
Here's an example:
import 'dart:async';
import 'dart:html';
import 'package:web_ui/web_ui.dart';
main() {
Timer.run(() {
var myElement = query('#my-element').xtag;
myElement.startAnimation();
});
}
This will get better with the ability to import components, directly subclass Element and maybe some lifecycle events that guarantee that you get the correct class back from a query(). This is what the exemple should look like in the future:
import 'dart:async';
import 'dart:html';
import 'package:web_ui/web_ui.dart';
import 'package:my_app/my_element.dart';
main() {
MyElement myElement = query('#my-element');
myElement.startAnimation();
}
