Array of different shapes
« on: Apr 9th, 2004, 11:03am » |

I was attempting to create an array of shapes for easier translation and such but I could not figure out which type of an array it need to be. I tried type Shape and I tried casting, niether which of worked. (Error: type "void" not valid..." Is there a simpler way to go about this?
- Thanks, Josh

Hmm, array of "shapes"? You mean rects, ellipses etc? Those are not actual classes, they are only functions that draw.
To do what you want you'd probably be best off creating a class to contain shapes. Calling it Shape won't work, by the way, since it collides with java.awt.Shape. Let's call it MyShape. A sample program could look like this:
Code:MyShape shape[];
static int RECT=0,ELLIPSE=1;
void setup() {
size(400,400);
shape=new MyShape[100];
shape[0]=new MyShape(RECT, -50,0, 10);
shape[1]=new MyShape(ELLIPSE, 50,0, 10);
}
void loop() {
translate(random(width),random(height));
fill(200,0,0);
shape[0].draw();
fill(0,200,255);
shape[1].draw();
}
class MyShape {
int type;
float x,y,rad;
MyShape(int _type,float _x,float _y,float _rad) {
type=_type;
x=_x;
y=_y;
rad=_rad;
}
void draw() {
if(type==RECT) rect(x,y, rad,rad);
else if(type==ELLIPSE) ellipse(x,y, rad,rad);
}
