Re: how to print string from array on screen from bottom to top?
« on: July 14, 2020, 02:58:50 pm »
Hi @ron77

Saw this at that other place! ;-)) translated it for QB64.

Code: QB64: [Select]
  1. ' save this file as test.bas
  2.  
  3. 'ref: https://www.freebasic.net/forum/viewtopic.php?f=2&t=28589#p272611
  4. REDIM lines(0) AS STRING
  5. readfile "test.bas", lines()
  6. upper lines()
  8.  
  9. 'append to the string array the string item
  10. SUB sAppend (arr() AS STRING, item AS STRING)
  11.     REDIM _PRESERVE arr(LBOUND(arr) TO UBOUND(arr) + 1)
  12.     arr(UBOUND(arr)) = item
  14.  
  15. SUB readfile (f AS STRING, lines() AS STRING)
  16.     DIM fline AS STRING
  17.     OPEN f FOR INPUT AS #1
  18.     WHILE NOT EOF(1)
  19.         LINE INPUT #1, fline
  20.         sAppend lines(), fline
  21.     WEND
  22.     CLOSE #1
  24.  
  25. SUB upper (lines() AS STRING)
  26.     'dim as integer h = hiword(width()) 'num columns on display
  27.     'print closing credits
  28.     FOR i = 0 TO UBOUND(lines)
  29.         LOCATE 24, 1
  30.         PRINT lines(i)
  31.         _LIMIT 1
  32.     NEXT
  33.     'clear screen
  34.     FOR i = 1 TO 25
  35.         PRINT
  36.         _LIMIT 1
  37.     NEXT
  39.  
  40.  
  41.  

This sol'n seems kind of jerky to me.

Better!

  1. ' save this file as test.bas
  2.  
  3. 'ref: https://www.freebasic.net/forum/viewtopic.php?f=2&t=28589#p272611
  4.  
  5. SCREEN _NEWIMAGE(640, 400, 32)
  6. REDIM lines(0) AS STRING
  7. readfile "test.bas", lines()
  8. upper lines()
  9. _PRINTSTRING (252, 184), "That's all folks."
  12.  
  13. 'append to the string array the string item
  14. SUB sAppend (arr() AS STRING, item AS STRING)
  15.     REDIM _PRESERVE arr(LBOUND(arr) TO UBOUND(arr) + 1)
  16.     arr(UBOUND(arr)) = item
  18.  
  19. SUB readfile (f AS STRING, lines() AS STRING)
  20.     DIM fline AS STRING
  21.     OPEN f FOR INPUT AS #1
  22.     WHILE NOT EOF(1)
  23.         LINE INPUT #1, fline

  26.     CLOSE #1
  28.  
  29. SUB upper (lines() AS STRING)
  30.     'dim as integer h = hiword(width()) 'num columns on display
  31.     'print closing credits
  32.     FOR y = 405 TO -16 * UBOUND(lines) STEP -1
  33.         CLS
  34.         FOR i = 0 TO UBOUND(lines)
  35.             _PRINTSTRING (10, y + i * 16), lines(i)
  36.         NEXT
  37.         _PRINTSTRING (600, 10), STR$(y)
  38.         _DISPLAY
  39.         _LIMIT 60
  40.     NEXT
  42.  
  43.  
  44.  

_PRINTSTRING is such a relief from errors when trying to print off screen (compared to LOCATE & PRINT BUT! who wants to go over graphics and SCREENs with really green newbie?)

My take on it:

Code: QB64: [Select]
  1. DEFLNG A-Z
  2.  
  3. CONST true = -1, false = 0
  4. CONST w = 800, h = 600
  5.  
  6. SCREEN _NEWIMAGE(w, h, 32)
  7.  
  8. RESTORE credits
  9. READ lineCount
  10. DIM text$(1 TO lineCount)
  11. FOR i = 1 TO lineCount
  12.     READ text$(i)
  14.  
  15. DIM y AS SINGLE, speed AS SINGLE
  16. y = h
  17. speed = .5
  18. centered = true
  20.     CLS
  21.  
  22.     y = y - speed
  23.     i = INT(y)
  24.     FOR t = 1 TO lineCount
  25.         IF centered THEN
  26.             leftside = (w - _PRINTWIDTH(text$(t))) / 2
  27.         ELSE
  28.             leftside = 150
  29.         END IF
  30.  
  31.         IF i >= -_FONTHEIGHT AND i <= h THEN
  32.             _PRINTSTRING (leftside, i), text$(t)
  33.         END IF
  34.         i = i + _FONTHEIGHT
  35.         IF i >= h THEN EXIT FOR
  36.     NEXT
  37.  
  38.     _DISPLAY

Re: how to print string from array on screen from bottom to top?

Aren't you guys over complicating a very simple process, for a learner?  Isn't this more or less what Ron was asking about -- "i have an array of string i wish to print the the string line after line from the bottom of the screen to the top like an ending title of a movie..."

Code: QB64: [Select]
  1. DIM TextArray(100) AS STRING
  2. FOR I = 0 TO 100
  3.     TextArray(I) = "Hello World" + STR$(I) ' a string
  4.     TextArray(I) = TextArray(I) + SPACE$(_WIDTH - LEN(TextArray(I))) 'with enough spaces to fill the entire line
  5.     'so we're certain that we erase anything that was written previously on the line.
  7.  
  8. FOR I = 0 TO UBOUND(TextArray) + _HEIGHT
  9.     LOCATE _HEIGHT - 1, 1 'print on the bottom few lines will scroll the screen automatically
  10.     IF I <= 100 THEN PRINT TextArray(I) ELSE PRINT 'so print the array + enough blank lines to continue to scroll it off the screen.
  11.     _DELAY .2

There's more comments in the above than there is code, and it seems to fulfill the original post's criteria.  ;)
