Well the sound can be heard!
There is no music.
The movement of scene is slow.
Using the keyboard and no Joystick there are two errors: if you push hardly the movement keys, you get on the screen garbage with multiple starship or part of starship moving with your "real starship.
And if you shoot and destroy an alien, the explosion moves on the screen together the hero starship!
More... when you shoot the game becomes very slow!
It will fine to test a compiled version of this game!

Putting a _LIMIT 10 into main loop the result does not change.

Below is the latest version 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.

' There is still a lot of work to be done to get this fully working,

' 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

I just remembered I had the Williams classics cartridge for Super NES, but I spent far more time playing Joust than Defender...
I learned something about this latest presented source code. That CONST has become worthless. Declaring a function that returns a constant offers the chance of typing that "constant". Also another function like CHR$() could be used for the constant value to return if desired, and it could be built up in a variety of ways. Could use another user function, and could even employ recursion with moderation. What I'm trying to say is that I'm not used to seeing source code with a function definition which is just "function_name = value".
I proposed the thing about "COMMON SHARED" because the original source code might have depended on other separate files, especially those not written in BASIC, to be compiled by QuickBASIC or BASIC PDS and not interpreted by QBasic.

I only know the IDE gives me no errors with the COMMON, and it blows up with DIM SHARED.
As far as constants, they can be shared variables - all the programmer has to do is remember not to change the values. Or they can be functions, and they can't make that error. Either way, it's just a way to assign a meaningful word to a value. Which is better, you can judge by how happy people are with them. Does one perform faster? Does one lead to more programmer errors? Is one costlier to implement and maintain? Maybe it doesn't matter. But I agree we should be able to assign a type to constants.
Hi MadSciJr
fine and hard your work on this oldQbasic code.
I'm tuning on the OUT /INP emulated into QB64pe!
I'm sorry but running the code posted by you at #12 I can appreciate your menù for game.
I have not understood why do you scramble KeyLeft and KeyDown?
I have tested keyboard with a good result for A,Z, N,M,K and spacebar.
Buuut running the game (option 1) is terrible!
Because 1 starship moves without any key pressed. 2. graphic makes garbage if you try to move Up/Down the starship. 3. graphic makes garbage is you fire with starship. Graphic is too fast and I must use on my PC a _limit 10 at the place of _limit cFPS (=30).
I hope that this my feedback should be useful for you that are working on it!

I haven't even looked at that yet. To start with I have been focusing on fixing the keyboard input. I also removed all the old adlib sound code - we can replace it with playing samples later (at one of those links they had WAV files of some of the sounds, the rest can be found online or pulled out of MAME).
(04-02-2023, 03:26 PM)TempodiBasic Wrote: I'm sorry but running the code posted by you at #12 I can appreciate your menù for game.
I just put in those very primitive menus to keep things simple for now.
The final game would have real menus and option screens that match the look of the real game, like TerryRitchie did in "Widescreen Asteroids".
(04-02-2023, 03:26 PM)TempodiBasic Wrote: I have not understood why do you scramble KeyLeft and KeyDown?
That's not from "Scramble". Sorry, I should have explained what I was doing. The original controls (up, down, thrust, reverse) are hard to use for a lot of people. But they are also part of the challenge of the game! But for beginners or people who just prefer a standard 4-directional joystick (actually 8-directional if we count diagonal movement), I want to include using the arrow keys to move up/down/right/left. So if you are pointing in one direction and the player presses the other way, the code will check the current direction the ship is facing: if they are facing the opposite direction then reverse direction else thrust. I have not added that code yet, just added some variables for it.

Yes it is a mess. I think it can be fixed, but one step at a time!

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).

I cannot play this game with a keyboard when the best experience was meant for a joystick. This is a mental block on my side. The original Defender on SuperNES was difficult enough and I could deal even less with Defender 2 on the same cartridge. Giving me a computer keyboard to control things is like torture LOL.

I hear you. We could always add joystick/gamepad support, want to give it a try? (I have code for that, but it's ugly.)

Hi MadSciJr
here a function routine to manage joystick/gamepad builded up for Defender
I have tested it by using an USB joystick like that of PS3 (12 buttons and 4 axis and no wheel)
with the ANALOGIC button not activated (the light on the Joystick is not on).
Code: (Select All)
I = _Devices
If I < 3 Then
Print " No joystick or gamepad detected"
End
Else
LB = _LastButton(3): ReDim LBu(1 To LB) As Integer
LA = _LastAxis(3): ReDim LAx(1 To LA) As Integer
LW = _LastWheel(3): ReDim LWh(1 To LW) As Integer
End If
Do
Locate 1, 1
If LBu(1) <> 0 Then Print "Button 1 " Else Print Space$(25)
If LBu(2) <> 0 Then Print "Button 2 " Else Print Space$(25)
If LBu(3) <> 0 Then Print "Button 3 Boost" Else Print Space$(25)
If LBu(4) <> 0 Then Print "Button 4 exiting": End Else Print Space$(25)
If LAx(1) = 1 Then Print "Boost " Else Print Space$(25)
If LAx(2) = -1 Then Print "UP-UP" Else If LAx(2) = 1 Then Print "DOWN-Down" Else Print Space$(25)
I = InputJoy(LB, LA, LW, LBu(), LAx(), LWh())
Loop
End
Function InputJoy (LB, LA, LW, lbu() As Integer, lax() As Integer, lwh() As Integer)
InputJoy = 0
x& = _DeviceInput 'determines which device is currently being used
If x& = 3 Then
For b = 1 To LB
lbu(b) = _Button(b)
Next
For a = 1 To LA
lax(a) = _Axis(a)
Next
For w = 1 To LW
lwh(w) = _Wheel(w)
Next
End If
InputJoy = -1
End Function
Later I try to put this my function into QB64 Defender for playing the game by Joystick.
