playn

问题 I have written a game in PlayN, which has to communicate with a JavaEE-Server with Seam. First of all I only need the game running in HTML5. The current issue is the communication between the PlayN-client and the JavaEE-Server 1) First I tried to communicate over the PlayN.net() interface exchanging information using JSON. Since PlayN is running on port 8888 and the server on 8080 I correctly run into problems with the same-origin-policy. 2) Now I'm looking for a working solution. Which one

问题 This is about as basic as it gets. I don't want to use an image file. Rather, I want to programmatically draw a circle and blit it to a surface (as they say in pygame). I tried to follow the "Using CanvasLayers" example here: https://developers.google.com/playn/devguide/rendering From my game class: // Surface SurfaceLayer surface; // Background int width = 640; int height = 480; //ImageLayer bgLayer; CanvasImage bgImage; Canvas canvas; // Circle CanvasImage circleImage; //ImageLayer

问题 I don't find a solution for this issue: I want to show my playN-game in a html-iframe: <iframe src="../playn-showcase-html/Showcase.html" width="640" height="480" name="Showcase" scrolling="no" marginwidth="0px" marginheigth="0px" frameborder="0" align="top"> </iframe> I want to embedd it with no borders. But as you can see in the image below, there is a 15px black 'rectangle' on top of the iframe I don't want to have. What one can see is the background of Showcase.html (which is black). As i

问题 I'm working on a game using PlayN, and there's a bit where I would like to take an image (which is currently in PNG format, with 8-bit alpha already) and I would like to multiply the image by an additional alpha factor, based on a value from my code. Specifically, I have a picture of a face that currently lives in an ImageLayer, and the effect that I would like would be to have something like this: void init() { faceImage = assetManager().getImage("images/face.png"); graphics().rootLayer()

问题 Currently I'm building it in Eclipse using the GWT plugin. I'd like to automate deployment to my development webserver using a script that does the GWT compilation from the command line. I've followed the directions in the Running Via Maven section of the Getting Started page: mvn -Phtml integration-test But it tries to build all the versions, erring out on the Android build (which I'd prefer to skip at the moment) and throws a warning stating the html profile doesn't exist: [INFO] ----------

问题 I have one little problem: I am trying go center a given text inside a Canvas with PlayN. I do not have any FontMetrics, because GWT does not offer one, and simple repositioning depending of character number and fontsize just does not works :(.. Can somebody please help 回答1: Use Graphics.layoutText to create a TextLayout . TextLayout provides the width and height of the text, which you can use to position it however you like and render it into a Canvas using Canvas.drawText(TextLayout,x,y) .

问题 I can run the Java version of my project fine by simply importing Guava libraries like so: import com.google.gwt.thirdparty.guava.common.collect.ImmutableList; Following the advice here, I've added this line to html/pom.xml: <dependency> <groupId>com.google.guava</groupId> <artifactId>guava-gwt</artifactId> <version>10.0.1</version> </dependency> And this line to html/project.gwt.xml file: <inherits name="com.google.common.collect.Collect"/> But when I try to GWT-Compile my HTML version in

问题 On a PlayN project I have the following Java code import com.google.common.base.Charsets; import java.nio.ByteBuffer; ByteBuffer msg = ... // a ByteBuffer that contains a String String s = Charsets.UTF_8.decode(msg).toString(); this works fine in Java, but when I try to compile it with GWT I get: The method decode(ByteBuffer) is undefined for the type Charset What's the proper way, in GWT, to obtain a String (encoded in UTF-8) that's inside a ByteBuffer? 回答1: You should be able to use new

问题 I've tried to follow the instructions on the getting started page for playn and run into problems when running the first program java showcase. I get the following errors when right clicking and running Maven test. Also I get numerous errors in the problem tab of eclipse related to (failure to transfer xxx from yyy) where xxx is some jar file and yyy is a gwt or playn website [INFO] Scanning for projects...

问题 I want to run my playN game in production mode as the development mode is too slow to test. I am not able to click and get the response for buttons and it updates very slow in dev mode. I have read that substituting the IP of the link with "localhost" will do. But even after i have done the same, It is too slow like before. I need to run the html version only. How can I do this? 回答1: You should try running it having the test-html profile active. From PlayN's getting started page: cd playn
