| Multi-Spacewar! v0.66 - improved ship + shot motion |

Simply changing the variables for x and y from integer to single sure made the ship movements a lot smoother!
I also fixed the heading of the shots to factor in the ship's motion.
Now it only takes 2 shots to kill a player, so it doesn't take forever to zap your opponents.
Feedback welcome!
Next I think it's time to start displaying scores and ship info properly around the edges of the screen. I'm toying with a cocktail cabinet mode, for those of you who like a classic arcade experience. But mainly we'll get that diagnostic text out of the way. Then we'll add some sounds, clean up the menu, add game controller support, and so on. The long term plan includes a ton of actually fun improvements, but the vision is to keep the feel of the 1960s thru early 80s vector games.
Code: (Select All) _Title "Fast Zap 'Em : Multispacewar! by Softintheheadware v0.66"
' Borrowed code:
' * Original VB6 code for "Collisions" by Tassadar, found on PlanetSourceCode.com in 2001.
' * Graphics objects and format from Widescreen Asteroids by Terry Ritchie.
' DATE WHO-DONE-IT DID-WHAT
' 2001-06-10 Tassadar created "Collisions" program
' 2022-11-01 madscijr Converted "Collisions" to QB64, added some tweaks
' 2022-11-04 madscijr Version 0.44 is now playable with up to 16 players
' 2022-11-06 madscijr Version 0.57, one player can control more than one ship.
' 2022-11-08 madscijr Version 0.66, fixed jerky ship movement + factor ship heading into shot heading
' DONE:
' * get it working in QB64 + tweak various calculations
' * random enemy radius (wider range with each level)
' * added variables for bullet lifespan, bullet radius
' * bullets can wrap around screen
' * bullet-bullet collisions
' * bonus shields at end of round
' * are you lookin' at me??
' * track x/y velocity differently (movement is jerky)
' * vector engine: define vector objects line by line and draw to screen
' * vector engine: translate rotation angle into dx,dy to move in direction of angle
' * local multiplayer Spacewar! (upto 16 players)
' * finish collisions
' - player hit player
' - player shoot player
' - enemy shoot enemy
' * 2-players control 16 ships (button #2 changes which ship)
' * fix jerky ship movement (ships should move & respond like Asteroids) = fixed by using Single instead of Integer!
' * factor ship's heading into bullet's speed
' TODO:
' * move scores + player status to top or edges of screen
' * fix player placement
' * sun and gravity
' * explosions and stuff
' * sound effects
' * cleanup/fix menu (breaks if we remove test items)
' * show player # or name on or near ship
' * improve collision detection accuracy
' * limited fuel/ammo
' * option: fire button auto-repeat
' (lots more plans for phase 2 and beyond)

'SUMMARY:
' Purpose: A library of custom functions that transform strings.
' Author: Dustinian Camburides (dustinian@gmail.com)
' Platform: QB64 (www.qb64.org)
' Revision: 1.6
' Updated: 5/28/2012
'SUMMARY:
'[Replace$] replaces all instances of the [Find] sub-string with the [Add] sub-string within the [Text] string.
'INPUT:
'Text: The input string; the text that's being manipulated.
'Find: The specified sub-string; the string sought within the [Text] string.
'Add: The sub-string that's being added to the [Text] string.
Function Replace$ (Text1 As String, Find1 As String, Add1 As String)
' VARIABLES:
Dim Text2 As String
Dim Find2 As String
Dim Add2 As String
Dim lngLocation As Long ' The address of the [Find] substring within the [Text] string.
Dim strBefore As String ' The characters before the string to be replaced.
Dim strAfter As String ' The characters after the string to be replaced.
' INITIALIZE:
' MAKE COPIESSO THE ORIGINAL IS NOT MODIFIED (LIKE ByVal IN VBA)
Text2 = Text1
Find2 = Find1
Add2 = Add1
lngLocation = InStr(1, Text2, Find2)
' PROCESSING:
' While [Find2] appears in [Text2]...
While lngLocation
' Extract all Text2 before the [Find2] substring:
strBefore = Left$(Text2, lngLocation - 1)
' Extract all text after the [Find2] substring:
strAfter = Right$(Text2, ((Len(Text2) - (lngLocation + Len(Find2) - 1))))
' Return the substring:
Text2 = strBefore + Add2 + strAfter
' Locate the next instance of [Find2]:
lngLocation = InStr(1, Text2, Find2)
' Next instance of [Find2]...
Wend
' OUTPUT:
Replace$ = Text2

I'm wondering how others do this....If you want to combine two or more programs together, how do you go about it?
For example if you have the IDE running but you want to copy a bunch of code from another program into it....do you use something like Notepad to have the other program open? I don't know of any way to open the IDE twice so I thought I'd ask here what others might do.

| Day 003: SGN |

A very simple and easy command to understand for day number 3 -- SGN.
What is SGN: It's simply the command to determine what sign a number has before it. Is it positive, negative, or 0?
When would we ever use such a command: Anytime we only need to know whether a value is less than, equal to, or greater than 0.
Example to showcase the command:
Code: (Select All) For i = -10 To 10
Print i, Sgn(i)
Next
Honestly, I don't know what more to say about this command as what it does for us is so simple to understand. Negative numbers return a value of -1. Positive numbers return a value of +1, and zero, of course, returns a value of 0 as it has no sign.

Multi-Spacewar! v0.57b - now 1 player can control >1 ships |
|
Posted by: madscijr - 11-08-2022, 12:20 PM - Forum: Works in Progress

With this latest version, each player can control more than 1 ship.
- From the menu, select Options (crsr down, crsr right).
The Options screen opens.
- Press 1/2 to increase/decrease players (1-16)
- Press 3/4 to increase/decrease # ships per player (upto 16 total among the players)
In this way you can select 1 player and control everything with player 1's controls:- cursor left/right = rotate ship
- cursor up = thrust
- right CTRL = fire
- right SHIFT = change which ship you are controlling
(cycles through the ships for that player, or control them all simultaneously)
Or you can select 2-16 players and play against one or more buddies.
The keys are mapped at line 2221 if you want to modify or see which keys do what.
If you don't want to crowd around a single keyboard, just plug in a second USB keyboard (I haven't tried it, but theoretically you can plug in as many keyboards as you have USB ports in your hub, just remember not to hit your opponent's keys! Perhaps one day we'll get the RawInput API working to read multiple keyboards as separate input devices, and then we can have some real fun!)
Any feedback is welcome.
PS I made further updates to add options to specify how many rounds are in a game, so when a player wins, a new round begins with all ships resurrected. However around v0.60 i went and broke something (the screen just goes blank when a new game is started - DOH!) so I have some debugging to do!
PPS Also, the ship movements work, but it still doesn't seem as natural and smooth as I would like, so I'll be working on that as well.
For now, this is the latest stable version...

Code: (Select All) _Title "Fast Zap 'Em : Multispacewar! by Softintheheadware v0.57"
' Borrowed code:
' * Original VB6 code for "Collisions" by Tassadar, found on PlanetSourceCode.com in 2001.
' * Graphics objects and format from Widescreen Asteroids by Terry Ritchie.
' DATE WHO-DONE-IT DID-WHAT
' 2001-06-10 Tassadar created "Collisions" program
' 2022-11-01 madscijr Converted "Collisions" to QB64, added some tweaks
' 2022-11-04 madscijr Version 0.44 is now playable with up to 16 players
' 2022-11-06 madscijr Version 0.57, one player can control more than one ship.
' DONE:
' * get it working in QB64 + tweak various calculations
' * random enemy radius (wider range with each level)
' * added variables for bullet lifespan, bullet radius
' * bullets can wrap around screen
' * bullet-bullet collisions
' * bonus shields at end of round
' * are you lookin' at me??
' * track x/y velocity differently (movement is jerky)
' * vector engine: define vector objects line by line and draw to screen
' * vector engine: translate rotation angle into dx,dy to move in direction of angle
' * local multiplayer Spacewar! (upto 16 players)
' * finish collisions
' - player hit player
' - player shoot player
' - enemy shoot enemy
' * 2-players control 16 ships (button #2 changes which ship)
' TODO:
' * move scores + player status to top or edges of screen
' * fix player placement
' * sun and gravity
' * explosions and stuff
' * sound effects
' * cleanup/fix menu (breaks if we remove test items)
' * show player # or name on or near ship
' * fix jerky ship movement (ships should move & respond like Asteroids)
' * improve collision detection accuracy
' * limited fuel/ammo
' * option: fire button auto-repeat
' (lots more plans for phase 2 and beyond)

'SUMMARY:
' Purpose: A library of custom functions that transform strings.
' Author: Dustinian Camburides (dustinian@gmail.com)
' Platform: QB64 (www.qb64.org)
' Revision: 1.6
' Updated: 5/28/2012
'SUMMARY:
'[Replace$] replaces all instances of the [Find] sub-string with the [Add] sub-string within the [Text] string.
'INPUT:
'Text: The input string; the text that's being manipulated.
'Find: The specified sub-string; the string sought within the [Text] string.
'Add: The sub-string that's being added to the [Text] string.
Function Replace$ (Text1 As String, Find1 As String, Add1 As String)
' VARIABLES:
Dim Text2 As String
Dim Find2 As String
Dim Add2 As String
Dim lngLocation As Long ' The address of the [Find] substring within the [Text] string.
Dim strBefore As String ' The characters before the string to be replaced.
Dim strAfter As String ' The characters after the string to be replaced.
' INITIALIZE:
' MAKE COPIESSO THE ORIGINAL IS NOT MODIFIED (LIKE ByVal IN VBA)
Text2 = Text1
Find2 = Find1
Add2 = Add1
lngLocation = InStr(1, Text2, Find2)
' PROCESSING:
' While [Find2] appears in [Text2]...
While lngLocation
' Extract all Text2 before the [Find2] substring:
strBefore = Left$(Text2, lngLocation - 1)
' Extract all text after the [Find2] substring:
strAfter = Right$(Text2, ((Len(Text2) - (lngLocation + Len(Find2) - 1))))
' Return the substring:
Text2 = strBefore + Add2 + strAfter
' Locate the next instance of [Find2]:
lngLocation = InStr(1, Text2, Find2)
' Next instance of [Find2]...

This demo code hangs up about 25% of the time, I can't close it, have to do kill it with the task manager to stop it. Dunno why. It only happens when the _ALPHA & _RGBA32 is used in the drawBall SUB. When I revert to the original SUB it never hangs. Any ideas? Using 32-bit version of QB64PE on Windows 7.

Basic Anywhere Machine (check it out)
What it is, the "short"(?) version:
Imagine Wikipedia (as in the software behind it), all existing in one self-editing and self-saving HTML file. Imagine it hosting a QB64 interpreter, IDE, all of the programming tools and programs, and everything to support all processes and artefacts for project management, source code management, and everything end-to-end in a software development process.
Still early going, but that's where it is heading.
And all you need is a web browser. Offline, online, fine. What you do with it will still work in 15 or 20 years. You won't need to find software or an operating system to run it. Just find a web browser. Everything else you need (every single thing other than a web browser) is in the one HTML file.
It is like a fully self-contained virtual computer that will have everything you need to manage QB64PE code for huge projects. Kind of like a QB64PE software development "bottle garden" (not sealed! you can still put stuff in it and get stuff out of it!)
Some technical clarifications:
Okay, it is not Wikipedia software. It is a "TiddlyWiki" instance. Because TiddlyWiki has the goods (goodies) to create just about anything. Don't let the cutesy name fool you. The thing is a powerhouse.
The embedded BASIC interpreter started off with vanilla wwwBASIC, but BAM's version is significantly enhanced. (An on-going process.) At the moment very focused on GW-BASIC "reasonable" compatibility before moving on to QB64PE "reasonable" compatibility. (I say "reasonable" because I cannot stand javascript, so updating the interpreter to handle the more intricate/complicated statements/functions/features, I just don't want to think of that just yet.)
Aside: - multi-member team software development project? That is a BASIC Anywhere Machine "TiddlyWiki Farm" running on a node.js server; awesome, but not required if you have good workflow processes.

[i]Note: Due to lack of interest in BASIC Anywhere Machine by the QB64 community, and unless interest in BASIC Anywhere Machine picks up, I'm (1) suspending posting updates about BASIC Anywhere Machine in the QB64(pe) forum and (2) suspending efforts to improve BASIC Anywhere Machine's compatibility with QB64/QB64(pe). If anybody wants to discuss BAM, I'm there for you, but I'm otherwise not bringing up my project.[/i]
Newly added to BASIC Anywhere Machine: Task Management
Newly added to "On the radar": - Ideas Management (A placeholder to manage ideas which may, or may not, turn into tasks, or requirements, or whatever)
Implemented:

Some folks mostly love to use programs, others love to develop them.
Out of curiosity, do you think if we had a lot of usable libraries on the boards, would you use them to build your programs, or prefer to make your own routines?
