with base you mean something like “basic concept” or “general approach”, right?
Remark 1
Woe, you can’t do this inside draw() :
for (int i = 1; i <= 50; i++) {
lines.add(new Line(i * 20 + 30, i));
Within seconds you have 19000 lines !
Do it in setup()
Remark 2
Your variable / object names are often too short: t, sb, r - it saves you a tiny bit of typing time but will cost you a lot of time to understand your code later!
Remark 3
This is not good:
for (int i = 1; i <= lines.size(); i++) { // ??????
Line l = lines.get(i - 1);
l.mousePress();
ArrayLists start at 0 so just start i with 0 and get rid of -1 in get(i - 1) also (and < instead of <=)
for (int i = 0; i < lines.size(); i++) {
Line l = lines.get( i );
l.mousePress();
OR just :
void keyPressed() {
for (Line l : lines) {
l.keyPress();
}
}
Remark 4
if (darkt == true) {
same as
if (darkt) {
Remark 5
if (darkt == false ) {
same as
if ( ! darkt ) {
Remark 6
Instead of searching the selected line number
for (Line l : lines) {
l.keyPress(); // only the selected line does something here!!!!
}
we could store the line number of the selected line.
No for-loop needed:
lines.get( numberOfTheSelectedLine ).keyPress();
Remark 7
I made a new version below.
I made a few changes.
I did key ENTER and UP and DOWN ( LEFT and RIGHT have to be done inside the class )
