Creating a custom renderer #2390
Description
Hi there, just working on something that will resolve the problems SMT was having with the latest version of processing - a custom renderer. I have it working fully on the desktop on Windows and Linux ( can't test on mac ). I ran into a problem on Android however.
This works on the desktop:
void setup(){
size( 800, 600, Renderer.class.getName());
}
void draw(){
background( 30);
fill( 200, 100, 100, 200);
noStroke();
rect( 10, 10, 100, 100);
}
/*
public int sketchWidth() {
return 800;
}
public int sketchHeight() {
return 600;
}
public String sketchRenderer() {
return Renderer.class.getName();
}
*/
public static class Renderer extends PGraphics3D {
public Renderer(){
super();}
}However this fails on android:
void setup(){
//size( 800, 600, Renderer.class.getName());
}
void draw(){
background( 30);
fill( 200, 100, 100, 200);
noStroke();
rect( 10, 10, 100, 100);
}
public int sketchWidth() {
return 800;
}
public int sketchHeight() {
return 600;
}
public String sketchRenderer() {
return Renderer.class.getName();
}
public static class Renderer extends PGraphics3D {
public Renderer(){
super();}
}With the following logcat output:

Help of any kind would be nice. Advice as to where to look and the like would be great.

hello, since this is an android issue could you re-open it on the processing-android repo?
