My Lunar Lander bloatware! (ver 0.33) - madscijr - 07-19-2022

I took the 30 line game by BPlus and force fed it, and now it's 1500+ lines!

It's still not Atari Lunar Lander, but getting there...!

My current challenge is doing sound effects from code without resorting to using separate sound files. The rocket sounds keep playing after the player stops pressing keys. How to make it stop? 

Enjoy

' DATE         WHO-DONE-IT   DID-WHAT
' 2020-11-15   bplus         fix off-sides x,
'                            add alternate keys: a=left d=right w=up
'                            so now arrow keys or WAD system works
' 2022-07-15   madscijr      changed variables to double to move lander a fraction of a pixel at a time
'                            display velocity, fuel, etc. on screen

' DONE:
' Change input to use _BUTTON instead of KeyHit
' Track velocity + lateral momentum + fuel
' Display altitude, velocity, fuel, etc.
' Pressing arrow up/down/left/right and 1-7 simultaneously selects which direction to thrust in, and power level.

' TODO:
' Better (graphic) display for fuel gauge, air speed, etc.
' If speed too fast, display in a different color or graphically warn player.
' Sound effects: engines, crash, warning beeps (low fuel, moving too fast, etc.)
' Simplify flames? Just draw a couple of lines instead of semicircles?
' Change surface of moon to vector lines.
' Map entire moon and scroll horizontally as lander drifts towards edges of screen.
' Zoom in as lander gets close to surface.
' Stars "cheap planetarium"
' Track + display oxygen
' Meteorites, UFOs + other phenomena
' Support game controllers?
' Get out and walk on the moon, collect rocks, meet moonmen, blast back off, rendevous, go home, splashdown, etc.
' Various missions - land, explore, take readings, rescue, salvage, mining, combat, set up moonbase, etc.

RE: My Lunar Lander bloatware! (ver 0.33) - SierraKen - 07-20-2022

LOL that is fun! For the sound, you might want to try short bursts of sound if it's possible. Or use the PLAY command to play an A note at 16 or 32. https://qb64phoenix.com/qb64wiki/index.php/PLAY

There might be other ways to do it too, I know that I use Dav's chimes for my clock that doesn't use either of those, it uses the _SndRawLen, _SndRaw, and _SndRate commands that I still have to figure out myself.

I saw those _SndRaw commands, briefly played with them, and didn't get too far.
It does look like it gives you low-level control, and I will spend more time reading about it.
Sound is one of those areas of QB64 that I need to learn more about. I would like to see the language expanded with higher level commands that let you have more control over audio, but maybe some of that functionality is already present. I need to study some _SndRaw examples and see what it can do...

Thanks! The fade out that eliminates the clicks after the sound is helpful. 

I see the comment "do other stuff, but it may interrupt sound" which leads to my next question - 
if it's a sound effect for a game, where we're constantly redrawing the screen, reading the keyboard for input, and making calculations, 
the sound effects need to be asynchronous. How do we get it to NOT interrupt the sound? 
When the player lets go of the "thrust" button, the engine sound should stop immediately, without any clicks. 

Here's my test harness where I am playing with your "chimes" code:

RE: My Lunar Lander bloatware! (ver 0.33) - SierraKen - 07-21-2022

Neat little experiment.

Yeah I think the PLAY command might be the only one that can play while the code keeps going. It uses the MB command inside the PLAY command to tell it to play that way. Here is an example I just made. MB sets it to play while it keeps going and the letters are the sound notes and the numbers are the duration of each note. 

You also can see many other commands that PLAY has here. There might be a way to make a ship sound with it, not sure. 
https://qb64phoenix.com/qb64wiki/index.php/PLAY

Code: (Select All)
Do
    t = t + 1
    Print t
    Play "MB a16b16c16d16e16f16g16"
Loop


RE: My Lunar Lander bloatware! (ver 0.33) - SierraKen - 07-21-2022

This might be a good engine sound, you can play around with it. The << sets the octave 2 times lower. 

Code: (Select All)
Do
    t = t + 1
    Print t
    Play "MB <<g32"

I might be mistaken but "PLAY" and "SOUND" are part of the deal for QB64 to emulate M$QB and GW-BASIC as closely as possible. Especially people using the latter product entirely expected sounds playing while doing something else such as keyboard input. It was crucial for those who were able to program impressive text-mode animations while complex music arrangements were being played.

You're better off at least using "_SNDOPEN", "_SNDPLAY", "_SNDSTOP", "_SNDVOL", "_SNDPLAYING" and "_SNDCLOSE", with external audio files. They could be in MP3 or OGG format which could be very small if one-channel and maybe 22050Hz sampling rate. Might want to take advantage of "_INFLATE" and "_MEMSOUND" to even include such a file into your source code. Otherwise "_SNDRAW" is the only way to start and stop sound at will.

I have to check out "_MEMSOUND" myself, but I'm not very comfortable programming for the "_MEM" gang. That statement is a lot like "Catchsound" in Purebasic, made it rather easy to bind media files into an EXE file. Sadly it might be for Windows only unless QB64 could recognize "zlib" on Linux.

EDIT: Uh about the code above, what is done with "t"? Because it's an endless loop.
