how to detect right mouse button press/release while left mouse button is plessed in P3D mode?

iizuna

Hello! I want to use both mouse button, but in P3D mode, mouseButton only returns left button.

void setup() {
  size(100, 100);
  //size(100, 100, P3D);

  fill(255);
}

boolean LMB, RMB;

void draw() {
  if (LMB) {
    background(0);
    if (RMB) {
      rect(30, 30, 40, 40);
    }
  } else {
    background(255);
  }
}

void mousePressed() {
  if (mouseButton==LEFT) {
    LMB=true;
  } else {
    RMB=true;
  }
}

void mouseReleased() {
  if (mouseButton==LEFT) {
    LMB=false;
  } else {
    RMB=false;
    if (LMB) {
      println("success");
    }
  }
}

This works, but doesn't in P3D mode. Please help me.

Indeed all renderers but JAVA2D is bugged for mouseButton under P3! :-O
You should report it here: https://GitHub.com/processing/processing/issues
Also mention your forum thread here there, so you don't need to explain from zero. O:-)

This is the rest of the full report below: :-B

• No bugs found at all under both P2 nor P1! <:-P
• Much probably it's gonna work alright up until version 3.0a5 too.
• It works relatively well under Pjs. Just some glitches though:
