I have using Texture array in augmented reality but run time show error "constructor are undefined".

I have using Texture array in augmented reality but run time show error "constructor are undefined"-in processing3...how to slove this error

koogs

Which constructor? What code is causing that error?

saurabh

"tex[0] = new Texture(this);" show constructor "Texture( )" does not exits

koogs

where is the Texture class defined? is it in a library? is it your own code?

saurabh

It is libraries class

koogs

Which libraries class?

This is like pulling teeth.

  if(movie[0].isPlaying()){
      if(time0==30.875){
          movie[0].jump(0);
      }
  }
}

this is my code, during run time show error

koogs

that's better, thanks.

the class is actually processing.opengl.Texture

which is here:

https://github.com/processing/processing/blob/81e86df8fd964aa95d506e30259a3d8fe459e79a/core/src/processing/opengl/Texture.java

the constructors for which are:

public Texture(PGraphicsOpenGL pg)
public Texture(PGraphicsOpenGL pg, int width, int height)
public Texture(PGraphicsOpenGL pg, int width, int height, Object params)

but you're passing 'this' which is resolving to your sketch.

i changed line 17 to

tex[0] = new Texture((PGraphicsOpenGL)g);

and that got further (line 22 is now giving an error). but i'm beginning to think that code isn't meant for processing3

(i am using a slightly older version of processing3, mind, 3.0b7)

koogs

yeah, setPixelDest() isn't defined on that class.

it IS defined on the old GSMovie class, which the new one is based on, but i can't see it in the new one.

saurabh

so how to solve that GSMovie error in latest processing version
