0 comments by carelesslabs on May 19th, 2014

Currently working on a game for Wing Wing Shoot Bag using Java with LibGDX. While trying to learn Pixel/Game art I produced a few animated GIFS, one of which would be perfect for the main screen. This concept will be developed further and used within Endure.

Being a little lazy I thought of loading in the individual images and looping through them rather than create one large image and cut it up programmatically for an animation. This worked, I had created a sort of slide player.

After pressing start within the game menu I wanted the current frame to pause and fade out, then the intro of the game would play. The intro follows the movie to which the game is based, several images would fade in, hold then fade out.

Fading in and out
First off I needed to find a way to fade an image in or out, there is a library available to do this: Code.google.com

I followed the guide and setup a Sprite Accessor class: Class source

Slide Manager
Next I created a slide manager class, this would hold an array of slides which could have some simple attributes:

  • sprite;              // The image
  • fade_duration  // Time to fade in or out
  • hold_duration  // Time to hold slide on screen after fade in
  • total_duration  // time for fade in, hold and fade out
  • gap_duration   // time between slides

Classes: Slide Class - Slide Manager

Creating and using the Slide manager
Basically you initiate the new class then add to the array of images with some settings. During the render loop you tell the class to update and it will play your images in order; fading them in and out.

// Declare a new var
SlideManager slide_manager;

// Slides
slide_manager = new SlideManager();

// Add slides that fade in for 4 seconds, holds for 1 seconds
// After fade out leaves a gap of 1 seconds before next slide

slide_manager.add_slide(new Slide("intro/screens/russian.png", 4, 1, 1));
slide_manager.add_slide(new Slide("intro/screens/spy.png", 4, 1, 1));

// Add a slide with an overlay animation
// Passes animation width, speed and position
slide_manager.add_slide(new Slide("bck.png", 2, 0, 1, "frames.png", 70, 0.1f, 45, 25));

I started playing about with a few variations of slides, would probably move the extras such as animations into an array and create a new animation class to pass with the slide.

This is a render loop for the intro screen, when the slides are done it just loads the next screen:

public void render(float delta) {
Gdx.gl.glClearColor(0, 0, 0, 0);

if (!slide_manager.finished){

if (slide_manager.finished){

This is a very quick prototype which only allows simple fading in and out and overlaying of one animation. It requires a library to be imported even though setting the colour(Alpha) of a sprite over time is very simple I could go on to use many more of the libs features.

This class will allows me to quickly create simple comic book style cuts scenes between levels while prototyping.

Just started again on this, working on multi-player version. I think it has to be multi player to make it more interesting. As @Jourdan_Cameron said, its a blank canvas right now.

Time to make some decisions and really get back into the project.

Thanks, I would like to get a demo out soon, as a one man team and two projects open at the moment I am a bit delayed with this one. Have big plans for it though

Thanks, the crafting system is in place right now, but there is only one recipe. It follows MC style crafting but I would like to expand on it later. I will add a few basic items and put an article up on crafting soon and look forward to feedback on it.
