Java Game APIs & Engines / Java 2D / Getting all available screen resolutions on Linux

on: 2013-03-11 20:57:19

Hey everyone,
I'm trying to fetch all currently available resolutions of the screen. The problem: I'm only getting the active screen resolution (on Linux). the following code works on Mac & Windows but not on Linux:

1
2
3
4
5
6
7

GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice display = ge.getDefaultScreenDevice();
DisplayMode[] availableModes = display.getDisplayModes();
      
for (DisplayMode mode : availableModes) {
    System.out.println(mode.getWidth() + "x" + mode.getHeight());
}

Any suggestions? Huh

Java Game APIs & Engines / Engines, Libraries and Tools / NiftyGUI: Problem with label control

on: 2013-01-30 16:56:11

Dear JGO,
I'm currently writing a game with Slick2D and NiftyGUI (v. 1.3.2). As always I've created a simple XML file with a center aligned panel. The panel contains two labels (horizontal oriented):

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24
25
26

?xml version="1.0" encoding="UTF-8"?>
<nifty xmlns="http://nifty-gui.sourceforge.net/nifty-1.3.xsd" xmlns:xsi="http://
www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://nifty-
gui.sourceforge.net/nifty-1.3.xsd http://nifty-gui.sourceforge.net/nifty-1.3.xsd">
<useStyles filename="nifty-default-styles.xml" />
<useControls filename="nifty-default-controls.xml" />
<screen id="start">
   <layer>
         <!-- Caption -->
         <panel childLayout="horizontal" align="center">
            <control
               id="lblCaption"
               name="label"
               color="#bccf39"
               text="caption"
            />
            <control
               id="lblVersion"
               name="label"
               text="version"
               marginLeft="10px"
               color="#ff6000"
            />
      </panel>
    </label>
</screen>

I can change the text content of those controls in Java:

1
2
3
4

// Inside a screen controller...
Label lblVersion = screen.findNiftyControl("lblVersion", Label.class);
Label lblCaption = screen.findNiftyControl("lblCaption", Label.class);
lblCaption.setText("A very long long long long long text!");

The text will be changed - but not the width of the label! The result: the text is cropped. That's very annoying. I've tried the following solution to solve the problem:

1
2
3
4

TextRenderer renderer = lblCaption.getElement().getRenderer(TextRenderer.class);
lblCaption.setWidth(new SizeValue(renderer.getTextWidth() + "px"));
// Update the panel and all children
lblCaption.getElement().getParent().getParent().layoutElements();

This works for me but it's not a very elegant way. Has anyone experience with this problem? Huh

Awesome game. So simple. I've reached 349 points...

I want to write my own 3D engine (in many many years...) and an infinite space game like Infinity from Keith Newton.

Never! Other guys play soccer, I'm programming instead. That's it.

Game Development / Newbie & Debugging Questions / Re: Java - Smooth tiles movement

on: 2013-01-22 21:28:43

The moving speed should be a float value like 0.2f. To calculate the total moving amount, multiply the speed with the current frame delta:

1	float speed = 0.2f * delta;

After that, you could move your tile (or game object, whatever) in any direction. After reaching the next tile cell, you can stop the movement (in a tile based map). Or how does your "tile" game look like?

I've played with camera zooming in Slick2D as well. With parallax scrolling and tile mapping it becomes a little bit tricky because you've to recalculate the camera size with the current zoom factor.

It's also important to include the natives for the operating system you're currently working with. In Eclipse IDE you can separately determine the native folder for each jar in the library path.

To make a game creepy, I'd like to use simple lighting effects (in 2D with alpha mapping, you could create torches with flickering lighting effects). Additionally, you could play with camera zooming and blurring effects. Scan lines are effective as well (vintage look & sometimes creepy). In fact, music and sounds can create a scary atmosphere. The game "SCP-087" uses several noises in order to create a creepy feeling.

I'm always using 800x600 during the development process. Higher resolutions are good but they often depend on the players available hardware.
