Questions tagged [slick2d]

Slick2D is a wrapper around the LWJGL OpenGL library for Java.

Slick2D is a simple, Java-based 2D game development library. You can read more about it on the Slick2D homepage.

The goal of Slick2D is to provide Java game developers with a library that handles gaming sub-systems, so the developer can focus on building their games. Library features include:

  • Hardware-accelerated graphics via a OpenGL
  • Complex audio rendering via OpenAL
  • Input handling for keyboards, mice, and gamepads/controllers
  • Several 2D game primitives, such as sprites, images, 2D tile maps
  • Geometry helper classes that facilitates collision detection
  • Path finding helper classes for path planning and route calculations

Slick2D is multi-platform, with desktop support for Windows, Mac OS X, and Linux. At the time of this writing, an Android Edition (SlickAE for Android development) has been discussed, but not released.

Note: The other slick tag is related to a Scala data access library, which is unrelated to this tag.

How can I prevent Alt key opening Dash Home while my Java app runs in Ubuntu?

I am learning Slick2D, which perfectly serves my purposes of 2D Java game programming. Unfortunately, I have a problem. I don't think it's Slick2D specific, since I think the same happens with Java Graphics 2D. In Ubuntu (I'm using Ubuntu 12.04),…

Java Slick scale Image without anti-aliasing

In the Slick library (based off of LWJGL), you can scale images after you load them with getScaledCopy, but it will apply anti-aliasing. I want the edges to stay rough; I'm making pixel art. How can I do this?

Write text on the screen with LWJGL

I want to write text on the screen for my game, for things like fps, random text for items and stuff. How can I write that text? Is it possible without the Basic Game class? Isn't there a command like this g.drawString("Hello World", 100, 100);?
