A command that's been around since the beginning of the language -- but also one that has expanded and evolved to make it much more flexible and powerful for modern programmers.
What is it? ASC is a simple little command which lets us to either set/get the ASCII value to/from a string character.
How do we use it?
To get a value, it's a simple function call like: value = ASC(a$, position)
To set a value, it's a simple sub call such as: ASC(a$, position) = 97
A simple example to showcase these methods a little:
Code: (Select All) Screen _NewImage(800, 600, 32)
a$ = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
'Back in the days of QB45, this is how folks made use of ASC:
For i = 1 To Len(a$)
temp$ = Mid$(a$, i, 1)
Print temp$; " = "; Asc(temp$)
Next
Sleep
'Then, along came QB64 with its first improvement!
'the ability to specify which byte we wanted!
For i = 1 To Len(a$)
Locate i, 20
Print Mid$(a$, i, 1); " = "; Asc(a$, i)
Next
Sleep
'Did you notice that we didn't actually need to use MID$ to get a single character anymore?
'Instead, we just specified which character we wanted to get the ASC value of, out of our string.
'And, as if that improvement wasn't enough, a SUB ASC was written for QB64!
temp$ = a$ 'a perfect match
For i = 1 To Len(a$)
Asc(temp$, i) = Asc(a$, Len(a$) - i + 1)
Next
Print
Print temp$
Sleep
'Notice how we just used ASC to assign characters to our string, based entirely off their ASCII value?
Cls
Print "ASC";
_Delay .5: Print ".";
_Delay .5: Print ".";
_Delay .5: Print "."
Print "Not the same old command that cavemen used to use when programming!"
Print
Print "You can now specify which byte you want the ASCII value of..."
Print "and you can now assign characters to a string with just their ASCII value."

Now with twinkling stars!
Code: (Select All) Dim Shared m_sTitle As String: m_sTitle = "2D Vector Shapes v0.20 by madscijr"
_Title m_sTitle ' display in the Window's title bar
' Simple test of vector graphics,
' borrowed graphics objects and format from Widescreen Asteroids by Terry Ritchie.
' DONE
' * We now can draw opaque shapes (still need to get working for shapes with non-contiguous areas)
' * Display looks prettier!
' - Shapes not active are drawn in an animated dashes
' - Text display is color coded to shapes
' * Tried adding twinkling stars (hard to see, need to fix)
' TO DO:
' * fix twinkling stars
' * encapsulate drawing shape in one routine
' * get fill working for shapes with non-contiguous areas)
' - define "fill coordinates" property or array
' - auto find these in shape
' - eliminate duplicates
' - store the remaining values store in shape data
' - use for PAINT when drawing fill color

'SUMMARY:
'[Replace$] replaces all instances of the [Find] sub-string with the [Add] sub-string within the [Text] string.
'INPUT:
'Text: The input string; the text that's being manipulated.

Mini-Monster-Mixer v0.1 generates a sprites sheet of 40 monster sprites at 64x64 pixels.
A source image of parts (included in the program code) has pieces that are randomly selected and recolored to generate the final images.
Press c or s to save the currently displayed sprites sheet to the clipboard if you wish. (to be pasted into any paint program afterward).

Print "So I can use a hole punch later with my printout and put my document inside a binder for a hardcopy!"
Print
Print
Print "And that's basically Steve's Lesson of Preparing for _PRINTIMAGE!"
Different people ask about how to get text and such on the screen to come out and look proper with _PRINTIMAGE. The above is generally the set up that I tend to use (though I'd often write several helper SUBs and FUNCTIONs to let them do the proper formatting so I don't have to keep typing LOCATE , LeftSideL: PRINT "" every time I want to print out to the screen...)
Step 1: Set your screen resolution to match the ratio of a page of paper. If your printer requires a border, subtract and account for that as well.
Step 2: If what you're printing needs to be preserved in a binder or such, preserve room for the hole punch to do its job without destroying your writing. All you need to do is have a hole punched once, removing several letters from a vital password, check sum, or credential, and you'll quickly learn why this is so important.
Step 3: Either set your screen to printing black on white by default, or else set up a quick toggle system such as the above. (Of course, the above is using some long and descriptive variable names which require a lot of typing... Let's be honest: either I would write a sub to handle this color inversion normally, or else my variable names would probably just become initials and much easier to type. Go with what suits you and your coding style the best.)
And with these steps basically in place, you're now set up to make a pretty little page which will print out and look almost exactly the same on your printer as it does on your monitor.

| DAY 013: _FONTWIDTH |
|
Posted by: SMcNeill - 11-18-2022, 12:46 PM - Forum: Keyword of the Day!

What is it?: _FontWidth is a nice simple function which tells us how wide the current font is for the screen we specify. (Or by itself, for the current _DEST screen.)
How do we use it?: We simply just call it like any other function. Something as simple as FW = _FontWidth will work just fine.
An example for people:
Code: (Select All) Screen _NewImage(800, 600, 32)
Print "Default font size:"; _FontWidth, _FontHeight
f = _LoadFont("courbd.ttf", 16, "monospace")
_Font f
Locate 3: Print "Courier Bold, 16, monospace font size:"; _FontWidth; " "; _FontHeight
f1 = _LoadFont("times.ttf", 20)
_Font f1
Locate 4: Print "Times New Roman, 20 font size:"; _FontWidth, _FontHeight
Copy. Paste. Compile. Run the code above.
Linux and Mac folks will probably get a whole bunch of zeros and maybe even a few error messages as no fonts are loaded. You'll need to adjust the links to wherever your fonts are found on your system, and then you can get some sensible results out of the above code.
As for Windows users, your fonts are in a standard place usually: C:\Windows\Fonts\... QB64-PE knows what folder to try and look for them at, so chances are everything will run as advertised for you guys, without any issues.
So what are the results once the proper fonts are found and pointed to??
Default Font Size: 8 wide, 16 high
Courier New, Bold, Font Size: 12 wide 16 high
Times New Roman Font Size: 0 wide 20 high
So, as everyone who's plotted text to the screen ever before should know, the standard font in qb64pe is 8x16 pixels in size.
The courier font, which I chose to load at size 16, happens to be 12 pixels wide and 16 pixels high.
The Times New Roman font however... ?????
How the heck is it 0 pixels wide????
It's not. 
When _FontWidth reports a font width of 0, what it's telling you is, "That's not a monospaced font."
Run the program once again. Look at the Times New Roman text on the screen. How many pixels wide is the "T"? "How many pixels wide is the "i"? Add the next two lines to the end of the program and run it once again, if you need to be convinced of the widths:
Code: (Select All) Locate 5: Print "TTT"
Locate 6: Print "iiiiii"
Six "i" characters are about the same width as three "3" characters! Times New Roman is a variable width font, and I didn't specify "monospace" when loading it, and as such it's impossible to say that the font's width is any set value. It's 0 -- variable width -- based upon which character is printed to the screen.
And that's the basic rundown on _FontWidth -- it'll basically tell you the width of the font on the screen you specify, or else it'll tell you ZERO, if it's a variable-width font.

Quick question.
Does anyone have instruction on how to create a simple database using QB64pe?
I need to record my blood sugar levels on a daily basis. Only three fields required. Date (automatic), Level and Comments.
Probably menu driven. Load, Save, Add, Edit, Exit etc.
I am not requesting anyone to write this. I would like to do that myself but I would need to know how...
Any advice or suggestions would be appreciated....
J
ps: Yes, I could probably use a DB application like LibreOffice to create it, but where is the fun in that? lol

Some updates
- We now can draw opaque shapes (still need to get working for shapes with non-contiguous areas)
- Display looks prettier! Shapes not active are drawn in an animated dashes, text display is color coded to shapes, etc.
- Tried adding twinkling stars (hard to see, need to fix)
We'll fix these problems and then get into - Collision detection
- Calculating the area of an irregular polygon
- Controlling the layer order for each shape
- Controlling rotation
- Composite shapes? Each sub-part can have its own color & collision detection, but they all move & rotate together.
Code: (Select All) Dim Shared m_sTitle As String: m_sTitle = "2D Vector Shapes v0.19 by madscijr"
_Title m_sTitle ' display in the Window's title bar
' Simple test of vector graphics,
' borrowed graphics objects and format from Widescreen Asteroids by Terry Ritchie.
' DONE
' * draw solid shapes (specify fill color and outline color)
' TO DO:
' * fix twinkling stars
' * encapsulate drawing shape in one routine
' * detect collisions
' * calculate volume of shapes (area of irregular polygon)
' * add z-order property to shapes for overlapping
' * fix fill for shapes with separate non-contiguous areas
' define "fill coordinates" property or array,
' auto find these in shape, then eliminate duplicates,
' then store the values store in shape data,
' and use for PAINT when drawing fill color?

I'm working on a prog that needs to sort a string, by swapping elements of the string.
Code: (Select All) Screen 9
_FullScreen
a$ = "ABCDEFG"
Print Mid$(a$, 3, 1), Mid$(a$, 5, 1)
swap mid$(a$,3,1),mid$(a$,5,1)

| DAY 012: _MOUSEMOVE |

Posted by: SMcNeill - 11-17-2022, 11:08 PM - Forum: Keyword of the Day!

This is one of those keywords of the day that Steve(tm) personally thinks is written poorly. Sure, it works, but in my opinion, it works backwards half the time. Let me explain in a moment, after I get the basics out of the way:
What is it? _Mousemove is simply a command to move the mouse cursor across your screen. It's not hard to figure out what this one does.
How does on use it? Simply add in a command for _MOUSEMOVE (x, y), and move that mouse cursor where you want it to go.
Now, why do it personally think it's poorly written?
Code: (Select All) For y = 1 To _Height
For x = 1 To _Width
Locate y, x: Print "ð";
_MouseMove x, y
_Limit 80
Next
Next
Sleep
In the code above, we're using _MOUSEMOVE with a SCREEN 0 text screen. _MOUSEMOVE here is moving by character position -- but if you look closely at the code above, you'll see that we're locating y, x and mousemoving x, y. In my opinion, if you're going to have a set coordinate system for a certain screen mode, then you need to stick to that existing coordinate system!
It's just a PITA to have to remember to swap over from row, column coordinates to width, height coordinates. Honestly, I think this may have been some sort of oversight when the code was originally written, but it's too late to change it now. Who knows how much old code might be broken by the swap? For better or worse, _MOUSEMOVE now will always run in width, height coordinates -- even in SCREEN 0 screens where we normally think in terms of row, column.
Be aware of this backwards coordinate system and don't like it bit you on the hiney, if you're ever coding in SCREEN 0. It's just one small aspect of an otherwise simple command to always keep in the back of your mind when working with it.
