screen 0 drawing - James D Jarvis - 07-09-2022
working on a" drawing" program for screen mode 0. There's no mixed-mode hijinks here it's just a simple means to draw screen-0 text based "graphics" with a mouse. This is a really early version and is a tool for another program so it's development is going to very much be a work in progress.
I just thought it would to be fun to share so people could see how a program evolves when I don't plan it (in this case because it's really just a tool to make images for another program).
Nothing images get saved yet.

How's your program coming along?
I didn't know "_PRINTSTRING" worked in "SCREEN 0" but it might be a bit of a hassle. I was going to ask you to check out my program "DRAW2004" but that was originally done in M$QB which is almost a totally new realm.
Programming for proper mouse input could be PITA. Once I tried to fix B+ "lights on" program I think it was, changed it so it accepted mouse input but it was a real battle. The great problem is when there is an area of the program window that must accept the input, and the user holds one of the mouse buttons while dragging the cursor to outside that area. Kept fixing it and encountered another problem of retriggering left button which is very annoying in a game.
Maybe for a screen-drawing program, retriggering isn't too bad but what if you desired to put a toolbar somewhere on the screen? I've actually attempted it. I have a program that works acceptably but don't use it much because of this problem registering the mouse events.
If "SCREEN 0" weren't so fussy I would recommend a way to create glyphs with "PSET", because sometimes this programming system doesn't display glyphs for ASCII codes below 32 and for many unicodes. On Linux I desired very much to capture some characters for video games, that I found in "gucharmap" program. Most of them don't display and "_MAPUNICODE" doesn't work properly in graphics mode or not.
RE: screen 0 drawing - bplus - 08-01-2022
As I recall, in Screen 0, or no Screen specified, all the x, y's are character cells columns and rows including mouse coordinates and _PrintString too? (Maybe not that one??) Pete's the expert on (Screen) Nothing LOL!
A quick experiment to confirm?
Yes! It's all in Char Cell "Locates"
Code: (Select All)
Do
While _MouseInput: Wend ' poll mouse
If _MouseButton(1) Then
_Delay .2
_PrintString (_MouseX, _MouseY), Str$(_MouseX) + "," + Str$(_MouseY)
End If
Loop Until Len(InKey$)Everything you do with pixels, just reimagine as char cells. And if you are a simple person you will love all the color choices! ;-))

Thanks. That area of the code has been neglected by me and will be getting more attention as I work on ways to save and load.

Quote:Programming for proper mouse input could be PITA. Once I tried to fix B+ "lights on" program I think it was, changed it so it accepted mouse input but it was a real battle. The great problem is when there is an area of the program window that must accept the input, and the user holds one of the mouse buttons while dragging the cursor to outside that area. Kept fixing it and encountered another problem of retriggering left button which is very annoying in a game.
