Displaying Last Lines of Array Text

in Programming Questions • 1 year ago

Hello

I would like to load a large text file but when it load I want to see the last line of my whole text at the bottom of the screen (instead of seeing the first line on the top of the screen).

I am following this post ( http://forum.processing.org/topic/large-text-on-screen) and using the code that is presented there. How can I change the display of the text lines to show the last line of the whole text appear on the bottom (and of course all the rest text appears above this).

Many thanks!

I took the code of the other thread and made some improvements:

int textY = 10;
int textX = 10;
int start = 0;
int numLines;
int yDist = 15;
String[] lines;
int bottom;
void setup() {
size(500, 400);
lines = loadStrings("G:/3rdPartyCode/Processing-1.5/processing/core/src/processing/core/PLine.java");
numLines = height/yDist;
bottom = (lines.length - numLines) * yDist;
textY = bottom;
}
void draw() {
background(0);
if (keyPressed) {
if (keyCode == DOWN) {
textY += 5;
if (textY > bottom)
textY = bottom;
} else if (keyCode == UP) {
textY -= 5;
if (textY < 0)
textY = 0;
} else if (key == 't') {
textY = 0;
} else if (key == 'b') {
textY = bottom;
}
}
start = abs(textY/yDist);
for (int i = 0; i < numLines; i++ ) {
text(lines[i+start], textX, (yDist * i), width, 20);
}
}

Many thanks, it seems to be working.

However, I noticed that if a message is big enough, it is chopped off by the end of the line.

I can't understand why, and I can't fix it!

Can someone tell me why?

I am trying to do it in different ways, like char.length or text.length, and another method found here.

However, cannot manage it to work.

Can this be done?
