Multi-Spacewar! v0.66 - improved ship + shot motion - madscijr - 11-08-2022
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
