B4A Library libGDX - Game Engine

Informatix · Sep 12, 2013

One of the best game engines for Android is now available to B4A users. Unleash your creativity!

You can read a description of this library in this guide.

Download for B4A v10.60 and older (4 MB)
Download for B4A v10.70 and newer (4 MB)

Starting from version 1.13, the library is compiled with Java 8, and thus requires a recent version of B4A and Java 8+.
To install the library, copy the .jar file and the .xml file in your libraries folder.

This library is not compatible with the Debug mode. Ensure that you always compile in Release mode.

Download also the examples and templates.

You can reduce the weight of the library if you want to keep your APK file as small as possible. Read this post to learn how to create your Lite version.

Sometimes I wonder whether some questions are serious or not. You have an error message saying "Missing parameter" and you ask what to do? Then, it's simple: add the missing parameter. This parameter, EvtPrefix, is present in hundreds of functions in LibGDX and in other B4A libraries and is described in the help of the function: prefix of the Completed event. If you don't want to use this event, put an empty string.

Yes I knew it really sounds stupid, but had a solution for it by now.

But can I ask you another question that may have some `challenge ingredient` in it:

Learning and testing using Andymc cloney bird game I wonder how to code
if a score reach every 50 or 100 another image beside "pipe" will appear, like:

B4X:

If Score>100 Then

............
End If

Thanks for now.

You have to use the mod function:
if Score mod 50 = 0 then 'the code after this will run every 50 pts

Thanks, I'm gonna try it.

Hi Fred,

I am loading an image using a texture. How do i set the gravity of the image.

Is it a good practice to scale the image to the device height and width and then set it as a background using texture

Or

Is there a way where i can crop the images using LibGDX.

Kindly let me know.

Regards,
Sk

I don't have any generic answer to your question as the Gravity setting does not exist outside of ImageViews and I don't know what you want to do exactly. For example, I could suggest to place an lgScn2DImage inside a lgScn2DTable, or to use a texture region.

I cannot give you a single answer. The visual result is completely different in these two cases (stretching vs. panning). To crop a texture, use a texture region.

You will need to run it in Release mode. Until B4A v3.50 the rapid debugger didn't support raising events from other threads.

The output of this demo is in the log as it does not demonstrate anything visual. Its goal is to load various assets with the lgAssetManager class.

I explained in post #208 that nothing visual is produced by this demo as it only loads assets. The output is in the log. So what do you expect?

Douglas Farias said:

As said in the first paragraphs of the introduction to libGDX, which is mandatory to read before using the lib, applications have to be run in Release mode only.

I never tried to add an ad banner in my projects but I suppose it's a panel that you put at the bottom of the screen. I suppose also that you put your LibGDx view just above so what's the problem exactly?

Hi Informatix,

So I found an issue using this approach. On my Galaxy S3, if I create a a LibGDx view that is anything but full screen, it has a negative impact on the frame rate - to the point where it gets very jerky. I create a surface:

B4X:

Dim surface As View

Then initialize it as a LibGDx view:

B4X:

surface = lGdx.InitializeView("LG")

Then add it to my activity, leaving a gap (iHeight) at the bottom:

B4X:

Activity.AddView(surface, 0, 0, 100%x, 100%y - iHeight)

When I do this & then run the app, I find that the frame rate is dropping down into the 30's & 40's. If I add the surface full screen:

B4X:

Activity.AddView(surface, 0, 0, 100%x, 100%y)

I don't see this problem. I don't see the same issue on my Nexus 7, but I think that's because it has a much faster processor.

Thanks - Colin.

I can't explain why. I tried to verify that on two of my devices less powerful than a Nexus 7 and was not able to reproduce it. Whatever the screen size or the method of initializing LibGDX (as a view or as a full screen surface), I got the same FPS.

You could try this:
in the Perf_skaters demo, note the FPS with 2000 sprites, then replace this line:
lGdx.Initialize2(Config, "LG")
by:
Activity.AddView(lGdx.InitializeView2(Config, "LG"), 0, 0, 100%x, 90%y)
Do you still notice a FPS difference?

Informatix,

I want to scale a ChainShape, but I can't find a method to do it. I though I'd be able to read each vertex, but have not found out how to read them individually and then scale their position and save them to a new array of vertices or just scale the shape as a whole

Is it possible?

I have no experience with ChainShapes. My first attempt would be to change the radius of the shape.

I resolved my issue as I was able to get the vertices from lgMapPolylineMapObject, however, You might want to look at GetVertex from lgBox2DChainShape. I had an XML error in the editor and couldn't figure out how to use it. The official libGDX docs show it takes an Index and Vertex, but that didn't seem to work in b4a.

Hmmm.... is there any obvious way of using some of the b4a output with apps created with this to load into Eclipse with libgdx and deploy to other platforms?

I will fix the documentation for the next version (you pass the index, and you get the result in the 2nd parameter). The help text of Radius needs a fix too (it should be "Gets or sets the radius of this shape.").

Hmmm.... is there any obvious way of using some of the b4a output with apps created with this to load into Eclipse with libgdx and deploy to other platforms?

Your code will not be compatible with the original libGDX. The wrapper for B4A does not consider other platforms and a few optimizations are made specifically for Android.
