Hi folks,
Trying to get on top of ArrayLists but I keep on hitting errors I can't make sense of. When I try and run it I get the following error: "The method add(Component) in the type container is not applicable for the arguments (ArrayList.FadingLine)".
I've looked through the reference and searched this forum and the old one, to no avail. Any suggestions for what I'm doing wrong or further reading would be appreciated!
- ArrayList list1;
- void setup() {
- size(500, 500);
- background(255);
- smooth();
- list1 = new ArrayList();
- list1.add(new FadingLine(random(0, width), random(0, width), random(0, width), random(0, width), 255)); //highlighted as error
- }
- void draw(){
- background(255);
- for(int i=1; i<list1.size(); i++){
- FadingLine lines = (FadingLine) list1.get(i);
- lines.drawLine();
- lines.update();
- }
- list1.add(new FadingLine(random(0, width), random(0, width), random(0, width), random(0, width), 255));
- }
- class FadingLine {
- float x1, y1, x2, y2, trans;
- FadingLine(float X1, float Y1, float X2, float Y2, float TRANS) {
- x1= X1;
- x2= X2;
- y1= Y1;
- y2= Y2;
- trans= TRANS;
- }
- void drawLine() {
- stroke (70, trans);
- line(x1, y1, x2, y2);
- }
- void update(){
- trans--;
- }
- }

). I've tried it with Processing 1.0.9, 1.2 and 1.2.1 (all downloaded with Java) and they all produce the same result, running on Vista Home Premium 32 bit. Just tested it on my girlfriend's laptop (also running Vista) with the same result.
