Support / Hello World - Demo
« on: March 27, 2018, 02:34:37 pm »
Hello All,

I am teaching Android UI development at a college in Canada and I would like to provide a very simplified demo of JPCL. It is not part of the curriculum but I thought that would be nice demo.

The idea was inspired on Prof. Giovanni Malnati  video:

However, I am having a hard time to make my demo to work. The App crashes while creating a framebuffer object. I tried GL ver 1 and a couple of other things and did not help. Following is the link for my App; in case someone would have some time to help would be great.

Thanks in advance,
Marcelo Varanda

Projects / Open Source Game: MulaKong
« on: April 13, 2016, 03:45:04 pm »
Hello All,

I have made MulaKong OpenSource as I had to slowdown my work hours for its development.
I believe that the logic is 1/3 done (as per my initial design) and Art the main models are completed. However, in my TODO list are:  Improve texture for the building, create surrounding buildings, streets, trees, sand beach, pick a better background (or SkyBox). Game is simple: prevent the Gorilla to reach the top of the building by shooting fruits. The first person is inside an helicopter (still missing a cockpit overlay) and flies around shooting the Kong. If he falls on the street than the player wins that phase.

Here is a demo recorded using the latest code:

Code and art are already available in GitHub. License is GPL v3. Link:

Have fun,

Bones / Overlaping bones Animation
« on: March 29, 2016, 03:30:55 am »

I have many individual animations working fine for my character. However, I would like to have smoother transitions. Is there an way to crossover the animations (weight ramps for in/out) ? I also have an independent head animation and I would like to play in combination with other bone animation sequences.

In case Bones Library provides this feature I would appreciate someone to point me out a demo code for it.

Thanks in advance,

Support / Texture with Alpha from Blender
« on: March 23, 2016, 02:37:05 am »
Hello All,

I am having some problems with a texture with some transparent areas. The building model have its balconies with a glass fence. It seems to work fine. However, the opaque regions where alpha are 1 are also transparent. My scene is created based on Blender Importer project (JPCTBlendScene). Has anyone experienced similar issue?

Support / samples under latest Android Studio
« on: March 11, 2016, 03:07:20 pm »
I really like everything I learned so far about this engine. A show stopper is the mess that Android did with this grable. I tried for 6 hours to get Bones and Ninja demos and so far no luck.

I tried using the AS project. It complains about missing android 4. Downloaded Android 4 and still no luck. Hacked the grable to set another API level, no luck. Tried to import Eclipse project. After many hacks still does not work. Tried to create a brand new project and move the java and libs. No luck either.

I completely acknowledge that all this nightmare is Google's mess. But it is being a show stopper for me. I would suggest to have contributors sharing successful projects for the latest AS for key features sample code. Otherwise, more people may give up for the stupid removal of gnumake and a gradle which does not provide any real and meaningful error messages.

Support / Prof. Giovanni's Video

Hello All,

I have placed a copy of Prof. Giovanni in my YT Account as private.

Does anyone have Professor's Giovanni contact? In case he authorizes to make it public then I would do so.


Support / choosing a game engine

Hello All,

I wrote in the past a couple mobile Games and Apps using BlackBerry Java, C++ (Gameplay3d), Objective-C.
I am starting a new simple game for Android (maybe port to iOS if game is successful). As the last GE I used was based on NDK portability was a bit of problem across the diversity of Androids themselves. I came across JPCT and it looks like a very solid project. Therefore, I would like to consider using it. I someone could help answering the following questions I would appreciate:

1- How lighter (or heavier) is jPCT comparing to Unity3D in terms of footprint and performance? a list of pro/cons on jPCT vs Unity would be very appreciated.

2- I am very proficient in Blender. How easy is to export models with Armature to jPCT? Is required another library?

3- I am not very familiar with the latest Android Studio. I was not able to run the two sample after frustrading hours dealing with gradle. Tried to run under Eclipse but was not much luckier. Is there samples out there that builds fine for the latest Android Studio (crappy gradle)

4- Would jPCT-AE  run under iOS in the future?

5- For I collaborated with a Blender add-on and a scene viewer for that engine. That made very easy to create a scene in Blender and see the very same in gameplay3d. Anyone wrote a similar utility using jPCT? That would be very handy.

Thanks a lot in advance,
