I enjoy "drawing" in text mode but it can be a pain juggling the print commands. I've posted and developed all sorts of complicated schemes for doing just that and I realized it is fairly simple to use ANY QB graphics commands to draw on a text screen. All one has to do is draw to an image buffer (which is a 32 bit image) with any standard graphics command, scan that and convert it to text "graphics".
Here's one way to do that:
Code: (Select All)
'---------------------------------------------------
'show draw header
'---------------------------------------------------
Dim Shared dspace& 'this is the drawing space/canvas that allows mixed mode graphics routines to function
Dim Shared ts& 'the text screen
Dim Shared stwd, stht
stwd = 80: stht = 40 'resize as you wish, on my monitor 2pixels wide per 1 vertical looks decent
ts& = _NewImage(stwd, stht, 0)
dspace& = _NewImage(stwd + 1, stht + 1, 32)
Screen ts&
_FullScreen
'-------------------------------------
'demo code
'-------------------------------------
Print "Plain old text screen set to 80 characters wide by 40 characters high."
Input "Enter a your name"; uname$
_Dest dspace& 'set the destination so graphics commands will be drawn into space&
Line (1, 1)-(stwd, stht), _RGB32(3, 176, 7), BF
Color _RGB32(15, 48, 0)
_PrintString (1, 1), "GIANT TEXT"
Circle (15, 15), 8, _RGB32(8, 72, 0)
Line (2, 2)-(20, 20), _RGB32(31, 176, 15), B
Color _RGB32(15, 48, 0)
_Dest ts& 'set the screen to the text screen
showdraw 1, 1, stwd, stht 'show dspace on the textscreen rendered in characters
Color 15, 0 'change the color it may be changed in showdraw
_Delay 1
Print "WELL WELL WELL"
_Delay 1
Cls
Print "WELL WELL WELL... you can use any standard graphics command."
Print
For cx = -5 To 90
Print "An animated circle, on a text screem."
_Limit 24
_Dest dspace& 'rember to set the destination to dspace& before you call showdraw
Line (1, 1)-(stwd, stht), _RGB32(8, 177, 7), BF
For bl = -20 To 80 Step 5
Line (bl, 1)-(bl + 6, stht), _RGB32(12, Asc("*"), 2)
Next bl
Circle (cx, 21), 5, _RGB32(15, 219, 0)
showdraw 1, 1, stwd, stht 'showdraw always writes to ts& so you don't have to change destination manually
Next cx
_Dest dspace& 'writitng to dspace& again
Color _RGB32(15, 219, 0) 'use color _RGB32( FOREGROUND_COLOR, DRAWN_CHARACTER, background_color) before printing to dspace&
_PrintString (1, 1), uname$
showdraw 1, 1, stwd, stht
Color 15, 0 'restoring to text mode colors white and black for foreground and background
Locate 1, 1: Print "BYE"
_Delay 1
'-----------------------------------------
'SHOWDRAW
'copies the image from the drawing space onto the text screen
'each pixel in dspace& will hold the text screen character and colors
'-----------------------------------------
Sub showdraw (xa, ya, xb, yb)
Dim tk As _Unsigned Long
'render from xa,ya to xb,yb from dspace& to the ts&
x1 = xa: x2 = xb: y1 = ya: y2 = yb
If x1 < 1 Then x1 = 1
If y1 < 1 Then x1 = 1
If y2 > stht Then y2 = stht
If x2 > stwd Then x2 = stwd
For x = x1 To x2
For y = y1 To y2
_Source dspace&
tk = Point(x, y)
Locate 1, 1
tc = _Red32(tk) 'the red color channel is foreground color for the text screen
ac = _Green32(tk) 'the green color channel is the ascii character to be drawn to the text screen
bc = _Blue32(tk) 'the blue color background color for the text screen
If tc > 0 Then
_Dest ts&
Color tc, bc
_PrintString (x, y), Chr$(ac)
End If
Next y

Since I'd rather code than write, I decided to present the KEYWORD of the Day, LOCATE in a brief demo. Reading the code window is also an easy option to obtain the various descriptions.
Just press a key during a pause to move on...
Code: (Select All)

FOR i = 1 TO _HEIGHT

PRINT: PRINT "Hmm, let's use LOCATE to fix that..."
SLEEP

_DELAY 1
msg$ = "That concludes this portion of our KEYWORD for the Day!"
LOCATE _HEIGHT \ 2, _WIDTH \ 2 - LEN(msg$) \ 2: PRINT msg$
END
Now naturally I did this for SCREEN 0. If anyone wants to elaborate on the use of LOCATE in a graphics environment, feel free.

The winner of this year's QB64 PE Winter Banner is bplus. The banner is now available. To view, you need to set your forum "Themes" to either "Default" or "Black" mode. To do so...
1) Scroll down to the bottom right of the page and locate the input field just left of the "Go" button.
2) Click the arrow to open the options, and click either "Default" or "Black" as your new forum page theme.
3) Click the "Go" button and our Winter Banner will appear.
Congrats again to Mark, and thanks for all the Christmas cheer.

So when it comes to subs and functions, which convention do you employ?
CALL MySub(Parameters)
or...
MySub Paramenters
Certainly the later is less typing. It also looks neater. That stated, I almost always write apps with 20 to 30 sub routines and maybe 40+ calls. For the simple reason of ease of search, I use the CALL convention. F3, type "CALL" and check match case and whole word. Easy peasy.
I have a feeling I'm going to be in the minority on this one, but let's find out.
So which convention do you prefer?
Pete
- You can CALL me Betty, and Betty when you CALL me you can CALL me Al, CALL me Al...
This program required Win32 API calls, so it will only run on a Windows system.
Custom window in that the code generates a small borderless window text window and adds a custom menu plus drag to move and drag to resize features. It does NOT use the QB64 RESIZE commands but does make use of the mouse cursor appearance changes. Thanks a ton to the dev who provided that neat QB64 mouse feature.
The top pseudo-title bar is functional. The three horizontal lines represent a pop-open menu. Click to open. The menu options are mostly for demo only, but close and quit do work. The symbols from top left to right are "-" Minimize, [] Fullscreen, and "X" Close.

Installed in this package is Qb64shell.bas which is the source..
The file contents are as follows:
Code: (Select All)
Information file for:
QB64SHELL - command line prompt shell windows program for QB64
Purpose:
Provides a low level DOS-like command shell program similar to the one
used by Windows CMD.EXE prompt. Tries to improve on most DOS functions,
such as: DIR, COPY, DELETE, MKDIR, etc. Also supports standard I/O
between commands and a full screen editor.
Installation:
Copy the QB64shell archive to C:\QB64 and extract contents there.
Load/Start or make .EXE then enter the shell at the command line.
Since QB64shell starts with user profiles activated, enter SYSOP
and PASSWORD to logon.
Files used:
QB64shell attempts to create the folder QB64shell in the \program files
group. The files in the folder are:
filemenu.cfg - config data for the file menu box
profiles.dat - user profiles data file
qb64shell.cfg - current state of QB64shell after exit
filename.cfg is written the first time QB64shell starts.
profiles.dat is written with SYSOP the first time QB64shell starts.
qb64shell.cfg is written every time the QB64shell exits and contains
such variables as the windows coordinates, statusbar setting, etc.
Any of these files may be safely deleted.
Compiling QB64shell:
The following files are required to make the QB64shell.exe program:
QB64shell.bas -- main QB64shell code
QB64shell.inc -- the QB64shell include file
QB64shell.ico -- the QB64shell icon file
QB64shell.new -- new version list file
QB64shell.txt -- readme file
Mem.h -- memory and cpu usage include file
THX_Sound_Effect.mp3 - intro sound
(only plays the first time QB64shell starts)
Author notes:
Program is published 11/30/2022 and is public domain BASIC source code.
