I'm having a little problem with SimpleOpenNI's Pointcloud. I'm trying to run the sketch page 115 from the book Making Things See, here's a copy of it :
I was supposed to have something like
this (picture taken from the book), but instead I got something like
that, with an incredibly low framerate (something like 2 images per second).
I thought it was a problem with Processing 2.0 and the changes made to P3D/OpenGL, but I created a Snow-Leopart partition on my hard drive and I tried to run the sketch on it with Processing 1.5.1 and I still have the same problem. I also tried to update my graphic card's driver, but it doesn't change anything at all.
Does anyone have an idea of what's going on ?
Note : I'm using Processing 2.0b7 on Mac OS 10.8.2 (Mountain Lion).
Thanks in advance :-) !
PS : I tried to run Dan Shiffman's PointCloud example from his Kinect library and it works fine, with a normal framerate.
I created a program/little game in which circles are falling from the top, and the player must avoid these circles by moving a pad (represented by a square).
I created three classes : one for the pad, an other for the circles, and an other that determines if a circle touches the pad.
I'd like to use variables from the class that contains the pad (like x and y positions) and from the one that contains the circles (x and y positions too) into my third class, so I could write something like "if the distance between the center of the circle is less than [width of the circle], the player looses one life".
Thing is, I don't understand how to "import" variables from one classe to another. I tried to write this :
class Bang{
float distance;
Spaceship spaceShip;
Monster monster1;
Monster monster2;
Monster monster3;
Monster monster4;
float Bang(){
spaceShip = new Spaceship();
monster1 = new Monster(color(60, 232, 49), random(125, 265), 0, 1);
monster2 = new Monster(color(240, 146, 31), random(125, 265), 0, 2);
monster3 = new Monster(color(18, 255, 253), random(125, 265), 0, 4);
monster4 = new Monster(color(242, 95, 95), random(125, 265), 0, 6);
distance = dist(xSps, ySps, xMstr, yMstr);
return distance;
}
void boom(){
if(distance<40){
life--;
}
}
}
(Spaceship is the name I gave to my pad, and Monsters is the name I gave to my circles falling from the top. ySps and xSps are the coordinates of the pad, and xMstr and yMstr the coordinates of the "monsters")
But it gives me this error message : the field Component.x is not visible. I guess it means the program doesn't find anything named "x" in the class, but I thought that by writing "Spaceship spaceShip; etc." before the constructor, it would also import the variables from those classes.
This is the first time I try to program something object oriented, I've searched solutions but I just don't understand how it works :-/
