color() method not working with setup()
« on: Aug 22nd, 2003, 7:37pm » |

i just encountered a strange bug:
when i type in this:
Code:
color c1 = color(255, 0, 0);
noStroke();
fill(c1);
rect(25, 25, 50, 50);
|
|
...i get a red square.
when i type in this:
Code:
color c1 = color(255, 0, 0);
void setup(){
size(100, 100);
fill(c1);
noStroke();
}
void draw(){
rect(25, 25, 50, 50);
}
|
|
...i would expect the same red square to be drawn, but what i get instead is a NullPointerException 
UPDATE
Duh! I was a bit to fast on this post. The reason must be, that I am using a native Processing command before the sketch is initiated, hence trying to call a color() method in native java, which causes an error (am I right on this one, I am expecting this is the same problem as trying to use native Processing language in an objects constrcutor class!)
anyway, this works:
Code:
color c1;
void setup(){
size(100, 100);
c1 = color(255, 0, 0);
fill(c1);
noStroke();
}
void draw(){
rect(25, 25, 50, 50);
}

nope, it's because that code gets run before setup, which means the colorMode() hasn't yet been set. color(x, y, z) scales the values by the current colorMode.
so it's not actually a bug, but (i think this came up elsewhere) maybe a default colorMode has to be set before setup() so that things like this work.
( it's not the same as the 'no p5 inside constructors' bug.. that's been fixed in 57/58 )
