jPCT-AE 3D engine Wrapper

[Erel]

Both debuggers will not work properly with libraries that raise events on threads other than the main thread. You will need to use Release mode.

Hi,

This is a great engine! I'd love to get pinch zoom working with the SurfaceTouch event but the JpctMotionEvent argument doesn't include pinch zoom, how would I implement this or is there already a library I can use for this?

Richard

 

[RichyK68]

Don't worry, I've answered my own question...I should be looking at the JpctScaleEvent argument instead.

 

[RichyK68]

Can anybody tell me why the scalefactor in the JpctScaleEvent structure is always returned as 1? It even does this in the demo. How do I find out how much the user has zoomed in or out?

Richard

 

[alienhunter]

maybe a dumb question is this possible to have the library running under Java FX (B4J) ?

 

[Reids]

Is it possible to merge with livewallpaper?
I tread put the example code to livewallpaper service but it force close, it would be great if this engine can be used as livewallpaper

 

[shaxboz]

Great Work! Thanks! One question, Can I use image file like a background. I saw all your examples back is colors, Is it possible to use images like that background?

The problem is not the JDK version (it only matters when you compile under Eclipse), it's because the sub has a name not compatible with the obfuscation mode. If you rename it Rendrer_FPS, that's OK.

Cheers for that, how did you work this out?

I'm not sure to understand the question.

I'm not sure to understand the question.

Ah, you mentioned that the name of the sub is not compatible with the obfuscation mode, how did you work that this was the case? i.e. rename from rendrerfps to rendrer_fps

I realise it was some time ago and may be blindingly obvious, but I can't quite see it. Just wanted to understand.

Because it's a common mistake. I created many libraries so I'm a bit used to this kind of error.

Hi ,
did anyone managed to make a polyline in space ? i do not get it how to

http://www.jpct.net/jpct-ae/doc/com/threed/jpct/Polyline.html

        Dim  ass As JpctSimpleVector
        Dim sss As Float
        Dim coords(3) As Float
        sss=0.4
        coords=Array As Float(sss,sss,sss)
        ass.Initialize5(coords)
      
        lines.Initialize(ass,SkyColor)

Your error is explained in the log: "required: SimpleVector[], found: SimpleVector". The Initialize function needs an array of SimpleVector.

sorry but how should this vector be defined ? that is what i do not get
thanks

Dim ass() As JpctSimpleVector

 

[alienhunter]

Dim ass() As JpctSimpleVector

dim ass() as Jcptsimplevector
ass(0)=1.0
ass(1)=1.1
ass(2)=1.2 ?

lol not a nice name for the vector

I don't use this library so I can only explain the reported error; I cannot say what you have to put in this array (probably the points of your line).

ok thanks for your time

The problem about "JpctPolyline" is that you can't create array of SimpleVector with the Project Wrapper of Alhowiriny


So one fix:

1°) With eclipse, Add this method in the class "JPolyline.java" in the Project Wrapper Source of Alhowiriny :

public SimpleVector[] essai(int dimension) {
SimpleVector[] ess=new SimpleVector[dimension];
return ess;
}


2°) With B4A, Use Pl_Line.essai(X) for create an array of X SimpleVector

Dim Pl_Line As JpctPolyline
Dim Pl_obj() As Object
Dim Pl_Tab(100) As JpctSimpleVector

Pl_obj=Pl_Line.essai(Pl_Tab.Length)
For i=0 To Pl_obj.Length-1
...
Pl_obj(i)=Pl_Tab(i)
Next
Pl_Line.update(Pl_obj)


3°) Good luck (it's not easy but it's work well)
