keyPressed failure?
Dec 2nd, 2006, 11:02pm  
hi there,
i've got a question aboute processing. when i use this code below, i can only increase the cubesize with 's' but don't decrease it with 'd'.

does anyone find the failure?
thanks in advance

//code
int cubeperline = 5;
int cubesize = 10;
int cubeabstand = cubesize+cubesize/2;
int r = 75;
int g = 150;
int b = 225;
int a = 100;


void setup() {
 size(800, 400, P3D);
 frameRate(30);
 }

void draw() {
 if (keyPressed) {
   if (key == 'd') {
     cubesize -= 0.01;
     }
   if (key == 's') {
     cubesize += 0.01;
     }
 }
 background(0);
 lights();
 stroke(255,255,255,15);
 fill(r,g,b,a);
 translate(mouseX,mouseY,0);
 for(int z = 0; z < cubeperline; z++) {
   for(int y = 0; y < cubeperline; y++) {
     for(int x = 0; x < cubeperline; x++) {
       translate(cubeabstand,0,0);
       box(cubesize);
       }
       translate(-cubeabstand*cubeperline,0,0);
       translate(0,cubeabstand,0);
     }
     translate(0,-cubeabstand*cubeperline,0);
     translate(0,0,cubeabstand);
   }
}

Hi,

Here is the workaround :

Quote:
float cubesize = 10;  
float cubeabstand = cubesize+cubesize/2;

Quote:
if (keyPressed) {
   if (key == 's') {
cubesize = cubesize+0.05;
   }
   if(key == 'd') {
cubesize = cubesize-0.05;
}
 }


You can also modify the cubeperline value by adding this in draw() following the previous code:

Quote:
if (keyPressed) {
   if (key == 'e') {
cubeperline = cubeperline+1;
   }
   if(key == 'x') {
cubeperline = cubeperline-1;
}
 }
