https://community.oracle.com/thread/1305696?tstart=0 Hi. I have an app deployed with java web start. It runs fine with java5. If i update the machines to java6 it works in some (windows and linux) but not on other (windows). The exception i get is: java.net.MalformedURLException: unknown protocol: socket Any ideas? Problem solved! I noticed that the full trace of the errors contained something about proxies, so I got my friend (who has Win XP Home) to: 1) go to Control Panel -> Java 2) click....
http://gafferongames.com/game-physics/fix-your-timestep/ Introduction Hello, I’m Glenn Fiedler and welcome to the second article in my series on Game Physics. In the previous article we discussed how to integrate the equations of motion using an RK4 integrator. Integration sounds complicated but really it’s just a way to advance the your physics simulation forward by some small amount of time called “delta time” (or dt for short). But how to choose this delta time value? This may ....
https://blog.csdn.net/csdnfengli/article/details/80695769 我在依赖自己公司提供的库的时候出现了unable to resolve dependency for app@…… 问题，有可能是网络设置出现问题，我的问题是studio的.gradle文件夹下出现了gradle.properties文本 同事文件夹后发先其他人并没有，里面配置了我的studio的全局设置导致我的网络一直走的代理，所以一直访问不到自己的库。解决方法是 注释掉所有内容，然后再设置studio中的设置便能生效。

I have not worked with the GWT, iOS or Desktop backends to see if/how they differ from the Android lifecycle. Libgdx Ap....

Today, I’ll be going over some code I put together to make a paged level selection screen with LibGDX’s Scene2D package. I endearingly refer to this as Angry Birds style, but it’s obviously not exclusive to A....
