Text() query using char arrays

in General Discussion • Other • 1 year ago

In the following example, why does the character array 'abcd' print in a different location to the string "efgh"?

size (100,100);
textFont(createFont("Arial", 20));
char[] c = {'a', 'b', 'c', 'd'};
String d = "efgh";
text(c, 0, 4, 40, 40);
text(d, 0, 4, 40, 40);

That's because the second and third parameter of text() is x- and y-position, if you pass a string.
If you pass a char-array, then the second and third parameter are the start-and stop-index of the array.
So you would have to write the following, if you want them in the same position:

text(c, 0, 4, 40, 40);
text(d, 40, 40);

I understand this now but the Description field in the Text() reference entry does not make this at all clear.

Right, but the syntax-field does.

text(chars, start, stop, x, y)
text(str, x1, y1, x2, y2)
