My problem is often that I need to make an asynchronous Firebase call within a function that I wrote. As a simple example, suppose I need to calculate & display the velocity of an object, and my Firebase stores distance & time: function calcVelocity () { var distance , time , velocity ; firebaseRef . once ( 'value' , function ( snapshot ) { distance = snapshot . val (). distance ; time = snapshot . val (). time ; velocity = distance

I'm using a simple calculation like this for it: v = oldV + ((targetV - oldV) * inertia) Applying that over a number of frames makes the movement 'ramp up' or decay, eg: v = 10 + ((0 - 10) * 0.25) = 7.5 // velocity changes from 10 to 7.5 this frame So I know the distance I want to travel and the acceleration, but not the initial velocity that will get me there. Maybe a better explanation is I want to know how hard to hit a billiard ball

I'm dealing with some Java code where Velocity 1.7 is set to retrieve templates through the ClasspathResourceLoader. Below is a stripped down sample of the code. It's from a Tapestry web application running on a Jetty server. The Java class, the templates and the file to be included are all are in the same folder "testpackage", so in the resulting JAR they are all in the same package "testpackage". The problem is that if the template contains an #include("MyInclude.vm") directive, Velocity cannot find "MyInclude.vm", and it throws a ResourceNotFoundException. Since in the argument of

And I've done that but no matter what I do I keep getting the same error. This is where I set the props and use velocity public class ConfirmationMailGenerator implements MailGenerator { private BasicUser user; private String htmlTemplate = "HTMLConfirmationMailTemplate.vsl"; private String plainTemplate = "PlainConfirmationMailTemplate.vsl"; public ConfirmationMailGenerator(BasicUser user) { this.user =

What I initially thought of doing was this: VelocityEngine ve = new VelocityEngine(); URL url = this.getClass().getResource("/templates/"); File file = new File(url.getFile()); ve = new VelocityEngine(); ve.setProperty(RuntimeConstants.RESOURCE_LOADER, "file"); ve.setProperty(RuntimeConstants.FILE_RESOURCE_LOADER_PATH, file.getAbsolutePath()); ve.setProperty(RuntimeConstants.FILE_RESOURCE_LOADER_CACHE,

For this I've set the followings, but reload doesn't work when I manually change a .vm file inside META-INF/template/ . velocimacro.library.autoreload = true [spring|file|class].resource.loader.cache = false Any idea? Here is my velocityEngine bean <bean id="velocityEngine" class="org.springframework.ui.velocity.VelocityEngineFactoryBean"> <property name="resourceLoaderPath" value="classpath:META-INF/template/" /> <property name="preferFileSystemAccess" value="false" /> <property name=

学习教程时，看到教程使用的springboot，在https://start.spring.io/上生成项目初始化文件时，自己操作时发现，2年前的教程，现在spring网站上已经搜不到velocity模板引擎了，做到教程模板引擎相关的操作时，就做不出来。倒腾了好几天，网上搜，有些解决方案，但是不太理解，也没成功，后来硬着头皮看了velocity英文官网，结合搜索时部分解决方案的启发，看到官网http://velocity.apache.org/download.cgi里的这段， Engine release notes dependencies . Inclusion as a maven dependency <dependency> <groupId> org.apache.velocity </groupId> <artifactId> velocity-engine-core </artifactId> <version> 2.0 </version> </dependency> 试着把这个依赖手动添加到pom文件中，成功了。非常激动。 文章来源: Spring Boot的新版本不支持velocity模板引擎解决方案
