The background is that I need to be in unity when I press a key and then show the information of the object that was hit by the Ray. The information of the object has been sorted into txt text before. Read it for a moment. Then there is a problem, because each object's introductory information is not the same length, then if the text within the text control is longer than the length of the display, more than the part will not be displayed. So what's the deal?

I was to facilitate the TXT text in all the text and symbols, and then all the newline character is the/n number of records, and then calculate the corresponding font size line has a few words, such as my 18th font, then one line can write 30 words, and then calculate the txt text in the number of words.

Then the length of the text box required = (number of total text/line of text + newline) * Length of line. Just like my total number of words is 2100, a line of 30 words, 19 newline characters, the length of a line is 16. The result is 1424 lengths.
