Hi again
MadSciJr your last code on running has problem to load font. The last previous one runs ok.
Looking at the code of QBDefender the input has been managed in the subroutine PROCESSGPI, here I will insert my routine later.
PS: my function shows all keyoptions except the change of direction (space bar) that can be managed by button 3 because boost has already its axis.

Make sure you're running the program loaded into the IDE - you can't just paste the code in and run.
I made that mistake and it said the font files were not found.
The program has to be saved to the same folder that the font files are located, before it will work.
Let me know if that works...
Thanks

Hi Madscijr
here a new step towards the porting into modern QB64 this old QBASIC version of Defender!
I add the Joystick control into Keyboardtest2, it works fine, I tested it with 2 different type of USB joysticks.
here the code
1. initialization for devices at beginning of the code
2. controlling input devices using a buffer , made by software, for managing command got from different devices.
In this settings the keyboard overwrites the joystick commands.
Code: (Select All) ' ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
' QB64 Defender v0.28.00
' Updated by madscijr Mar-Apr 2023, to sort of work with QB64 & QB64PE.
' There is still a lot of work to be done to get this fully working,
' and be more faithful to the original arcade game by Williams Electronics.

' Thanks for downloading my program. This is dedicated to
' those who said it could not be done!
' This was one of my earlist Qbasic programs so the code may be
' a little crude. The adlib routines for instance have been
' replaced in later programs with playback routines that are
' much smaller. If you have my FX program you know these playback
' routines have come a long way.
'
' But after all these years it's I think it's still a good looking
' program. Enjoy!

' For best results run this program under dos mode in WIN 95 and

Thanks Tempodi for helping with this!
I don't have my game controllers here right now, so I can't test yet that part.
However I did make some updates to your latest version, so the game still works using the keyboard if no joystick is present. If joystick is found bDetectedJoystick%=TRUE else bDetectedJoystick%=FALSE.
I also added a change log and cleaned up the code a little. I think that there should be an input mapping function that lets the user map any combination of keys or game controller input to any game function. Here is the latest, let me know what you think.
Eventually I would like to fix the "Common Shared" to be "Dim Shared" and bring any other old QuickBasic code up to date with modern QB64/QB64PE standards.
I think making Defender would be good, but adding all the enemies and features of Stargate (AKA Defender II) and making that an option (or perhaps the game progresses to Stargate at later levels) would be much cooler!
Really this game is probably a little advanced for me to do the way I'd like, this is the kind of game that would need someone like Terry Ritchie or RokCoder, to make it as good as the original arcade version. But if you want to try, that's cool!

' Here's an ancient QB version of Defender by Tim Truman from the 90s.
'
' The original "QBDEFEND.BAS" failed because of deffn, so I turned that into a
' function. It now runs but way too fast, so I added _Limit at line 248, which
' brought it back to normal speed. That version is "QBDEFEND_v2.BAS".
'
' (I tried cleaning it up some more but "QBDEFEND_v8.BAS" fails with a
' subscript out of range error at line 2784.)
'
' There are probably bigger problems with the program - ancient joystick, timer,
' adlib routines, writing to adlibs registers, a whole lot of stuff I don't
' understand.
'
' If anyone wants to play with it, I am attaching the code!

' Thanks for downloading my program. This is dedicated to
' those who said it could not be done!
' This was one of my earlist Qbasic programs so the code may be
' a little crude. The adlib routines for instance have been
' replaced in later programs with playback routines that are
' much smaller. If you have my FX program you know these playback
' routines have come a long way.
'
' But after all these years it's I think it's still a good looking
' program. Enjoy!
'
' Notes:
' For best results run this program under dos mode in WIN 95 and
' have a gamepad handy.

here a new step towards the porting into modern QB64 this old QBASIC version of Defender!
I add the Joystick control into Keyboardtest2, it works fine, I tested it with 2 different type of USB joysticks.
here the code
1. initialization for devices at beginning of the code
2. controlling input devices using a buffer , made by software, for managing command got from different devices.
In this settings the keyboard overwrites the joystick commands.
...
If you agree it can be copied into processgpi SUB or if you prefer we can use the controlo library of Terry Ritchie!
Waiting feedbacks.
Thanks Tempodi for helping with this!
I don't have my game controllers here right now, so I can't test yet that part.
However I did make some updates to your latest version, so the game still works using the keyboard if no joystick is present. If joystick is found bDetectedJoystick%=TRUE else bDetectedJoystick%=FALSE.
I also added a change log and cleaned up the code a little. I think that there should be an input mapping function that lets the user map any combination of keys or game controller input to any game function. Here is the latest, let me know what you think.
Eventually I would like to fix the "Common Shared" to be "Dim Shared" and bring any other old QuickBasic code up to date with modern QB64/QB64PE standards.
I think making Defender would be good, but adding all the enemies and features of Stargate (AKA Defender II) and making that an option (or perhaps the game progresses to Stargate at later levels) would be much cooler!
Really this game is probably a little advanced for me to do the way I'd like, this is the kind of game that would need someone like Terry Ritchie or RokCoder, to make it as good as the original arcade version. But if you want to try, that's cool!

' DATE WHO WHAT
' -------------- ------------ ---------------------------------------------
' 04/25/2023 Tue Madscijr v0.30: Cleaned up code, added change log,
' moved joystick test into its own routine
' JoystickTest1, while KeyboardTest2 is for
' testing keyboard. Added "test joystick' option
' to menu. Main game code does not yet have
' joystick support. Eventually the game should
' allow the player to map any combination of
' keyboard and game controller input to the game.
' 04/25/2023 Tue TempodiBasic v0.29: Added joystick support (InputJoy reads
' joystick, KeyboardTest2 modified to use it).
' 04/02/2023 Madscijr v0.28: Added 4-way control option (called
' "directional thrust" in the code). You can
' now use the arrow keys to move in a given
' direction (the standard controls also work).
' Also changed the FPS to 10 per Tempodi
' (this can be changed at line 80).
' 04/01/2023 Madscijr v0.27: hacked to accept keyboard input using
' _BUTTON. Added some code to prevent certain
' buttons (reverse direction, fire, smartbomb)
' from repeating if held down, but it wasn't
' working for the "Reverse" control (spacebar).
' It may need changing to use a different key?
' Added some variables for additional controls,
' but not yet implemented. Per mnrvovrfc, tried
' changing "common shared" to "dim shared" and
' the IDE started throwing strange errors.
' 03/29/2023 Madscijr v0.08: Tried cleaning up code some more but
' game fails with a subscript out of range error
' at line 2784.
' 03/28/2023 Madscijr v0.02: Added _Limit at line 248 to slow game down.

' I did a quick update to add the 4-way control option (called "directional thrust" in the code).
' You can now use the arrow keys to move in a given direction (the standard controls also work).
' I also changed the FPS to 10 per Tempodi (this can be changed at line 80).

' Below is the latest version 0-27 of the code which runs without blowing up.
' The attached archive contains a couple of font files you will need.
'
' It's hacked to accept keyboard input using _BUTTON.
'
' I added some code to prevent certain buttons (reverse direction, fire, smartbomb)
' from repeating if held down, but it wasn't working for the "Reverse" control (spacebar).
' It may need changing to use a different key?
'
' I added some variables for additional controls, but not yet implemented.
'
' Hey mnrvovrfc, I tried changing "common shared" to "dim shared" and the IDE
' started throwing strange errors.

' Here's an ancient QB version of Defender by Tim Truman from the 90s.
'
' The original "QBDEFEND.BAS" failed because of deffn, so I turned that into a
' function. It now runs but way too fast, so I added _Limit at line 248, which
' brought it back to normal speed. That version is "QBDEFEND_v2.BAS".
'
' (I tried cleaning it up some more but "QBDEFEND_v8.BAS" fails with a
' subscript out of range error at line 2784.)
'
' There are probably bigger problems with the program - ancient joystick, timer,
' adlib routines, writing to adlibs registers, a whole lot of stuff I don't
' understand.
'
' If anyone wants to play with it, I am attaching the code!

'
' Thanks for downloading my program. This is dedicated to
' those who said it could not be done!
' This was one of my earlist Qbasic programs so the code may be
' a little crude. The adlib routines for instance have been
' replaced in later programs with playback routines that are
' much smaller. If you have my FX program you know these playback
' routines have come a long way.
'
' But after all these years it's I think it's still a good looking
' program. Enjoy!

' Notes:
' For best results run this program under dos mode in WIN 95 and

Hello,
I have run this your last version and I found it good.
So following your developments
for Keyboard input I added the control buffering input so to let integrate it with others easily (the subroutine has changed in part)
for joystick I REMmed the keyboard input AND I wrote the same behaviour for the left/right directional input commuting this in a trhust or a reverse input following the logic, same direction gives trust while different direction gives reverse.
Well, this is the actual result

' CHANGE LOG
' ================================================================================================================================================================
' DATE WHO WHAT
' -------------- ------------ ---------------------------------------------
' 04/25/2023 Tue Madscijr v0.30: Cleaned up code, added change log,
' moved joystick test into its own routine
' JoystickTest1, while KeyboardTest2 is for
' testing keyboard. Added "test joystick' option
' to menu. Main game code does not yet have
' joystick support. Eventually the game should
' allow the player to map any combination of
' keyboard and game controller input to the game.
' 04/25/2023 Tue TempodiBasic v0.29: Added joystick support (InputJoy reads
' joystick, KeyboardTest2 modified to use it).
' 04/02/2023 Madscijr v0.28: Added 4-way control option (called
' "directional thrust" in the code). You can
' now use the arrow keys to move in a given
' direction (the standard controls also work).
' Also changed the FPS to 10 per Tempodi
' (this can be changed at line 80).
' 04/01/2023 Madscijr v0.27: hacked to accept keyboard input using
' _BUTTON. Added some code to prevent certain
' buttons (reverse direction, fire, smartbomb)
' from repeating if held down, but it wasn't
' working for the "Reverse" control (spacebar).
' It may need changing to use a different key?
' Added some variables for additional controls,
' but not yet implemented. Per mnrvovrfc, tried
' changing "common shared" to "dim shared" and
' the IDE started throwing strange errors.
' 03/29/2023 Madscijr v0.08: Tried cleaning up code some more but
' game fails with a subscript out of range error

' Hi Madscijr
' here a new step towards the porting into modern QB64 this old QBASIC version
' of Defender!
'
' I add the Joystick control into Keyboardtest2, it works fine, I tested it
' with 2 different type of USB joysticks.
'
' here the code
' 1. initialization for devices at beginning of the code
' 2. controlling input devices using a buffer , made by software, for managing
' command got from different devices.
' In this settings the keyboard overwrites the joystick commands.
'
' If you agree it can be copied into processgpi SUB or if you prefer we can use
' the controlo library of Terry Ritchie!
' Waiting feedbacks.
' Updated by madscijr Mar-Apr 2023, to sort of work with QB64 & QB64PE.
' There is still a lot of work to be done to get this fully working,
' and be more faithful to the original arcade game by Williams Electronics.
'
' The original version of this game is from Tim Truman's AOL site
' backed up at archive.org at:
' https://web.archive.org/web/20050324100845/http://members.aol.com/Timtruman/Qbasic/Games/qbdefend.htm

' I did a quick update to add the 4-way control option (called "directional thrust" in the code).
' You can now use the arrow keys to move in a given direction (the standard controls also work).
' I also changed the FPS to 10 per Tempodi (this can be changed at line 80).
' -----------------------------------------------------------------------------
' From: Madscijr
' Date: 4/1/2023
' -----------------------------------------------------------------------------
' Below is the latest version 0-27 of the code which runs without blowing up.
' The attached archive contains a couple of font files you will need.
'
' It's hacked to accept keyboard input using _BUTTON.
'
' I added some code to prevent certain buttons (reverse direction, fire, smartbomb)
' from repeating if held down, but it wasn't working for the "Reverse" control (spacebar).
' It may need changing to use a different key?
'
' I added some variables for additional controls, but not yet implemented.
'
' Hey mnrvovrfc, I tried changing "common shared" to "dim shared" and the IDE
' started throwing strange errors.
'
' The original download is from Tim Truman's old site backed up at archive.org.

' Here's an ancient QB version of Defender by Tim Truman from the 90s.
'
' The original "QBDEFEND.BAS" failed because of deffn, so I turned that into a
' function. It now runs but way too fast, so I added _Limit at line 248, which
' brought it back to normal speed. That version is "QBDEFEND_v2.BAS".
'
' (I tried cleaning it up some more but "QBDEFEND_v8.BAS" fails with a
' subscript out of range error at line 2784.)
'
' There are probably bigger problems with the program - ancient joystick, timer,
' adlib routines, writing to adlibs registers, a whole lot of stuff I don't
' understand.
'
' If anyone wants to play with it, I am attaching the code!

'
' Thanks for downloading my program. This is dedicated to
' those who said it could not be done!
' This was one of my earlist Qbasic programs so the code may be
' a little crude. The adlib routines for instance have been
' replaced in later programs with playback routines that are
' much smaller. If you have my FX program you know these playback
' routines have come a long way.
'
' But after all these years it's I think it's still a good looking
' program. Enjoy!

Waiting feedbacks I ask you :
in a mappable input from a device (think about keyboard), is the actual structure of defining value of keys, axis and wheels able to front this task?
in the original Defend is available the use of mouse as input device?

Hey
I have just tried to run the game (option 1) and I got an error at line 2115! It seems that there is a problem with variable maxcolonists.
Reading at starting file there are some DIMming of array with dimension maxcolonists while maxcolonists is one of the Common Shared variable, but it has been initialized into the code after these declaration of arrays.
Moving these initializations of variables at the bottom of the are Common Shared, the game starts to work with all its inner problems about graphics and sounds.
Here Screenshot
![[Image: image.png]](https://i.ibb.co/WK7V0kP/image.png)
this is the block of initialization moved at the bottom of Common Shared variables
Code: (Select All) ' SET VARIABLES TO MAXIMUM ARRAY SIZES
maxaliensinplay = 10 ' most on playfield
maxherolasers = 3 '
maxalienbolts = 1
maxcolonists = 10
maxgrabbers = 15
maxbomers = 2
maxchunks = 20
Waiting your feedbacks

Strange, I could have swore it ran before posting that code, but yeah, the declarations need to come before variable assignment. As a general rule I always like to declare my variables all together near the top. First constants, second types, third shared variables.
Another thing to fix I realized is the test for the presence of a joystick needs to come inside the menu loop, at the top. That way you can plug a controller in without having to restart the program.
If we want the real arcade graphics, we will need to go download the sprite sheet from the link in the program comments, this page, and rework it to use sprites. Also will need to fix the routines that draw the landscape.
More later when I'm back at the computer!
