How do I draw inside a class? about -dashed-lines-for-processing- HOT 2 OPEN

this needs to be a reference to your main PApplet, that is, the main Processing sketch. If you are using dashed lines inside a class, the class needs to have a reference to the PApplet object.

Try changing the constructor to:

ObstaculoNvl3 (PApplet sketch, int NdP, float X, float Y, int R) {
NdPontas = NdP;

Raio = R;

Ang = radians(360/NdP);

PX0 = X;
PY0 = Y;

RaioT = (Raio*2)/3;

tracejado = new DashedLines(sketch);
tracejado.pattern(30, 10);

}

And the, when you construct ObstaculoNvl3 from the main sketch, call it like:

ObstaculoNvl3 obs = new ObstaculoNvl3(this, ...);

Thank you so much, you saved me.
