Hi Peter,

Your GDIPlus include file looks very much like sw.inc. Would it be worth converting the SB SokoMouse game to GDIPlus or is this a one time experiment and there will be no further updates to this library?

I will wait until you give the green light.

Thanks!

Sadly, we cannot use GdiPlus for games, is too slow.

Why am I not surprised?

Thanks for posting this game. I will convert it to SB. Maybe more Basic programmers will use ScriptBasic if they can easily create simple games.

BTW: Do you have any more level maps for SokoMouse beyond the 9 that were provided?

JRS · « **Reply #4 on:** March 16, 2013, 11:13:59 AM »

My error. There are 30 maps. Sorry.

Here is your Bird Shooter game running in ScriptBasic.

@Peter: Other than trying to dodge the turds, how does the plane fight back (shoot, ...) You have a couple lines of code that checks for the Key() to be two different values at the same time.

That is what I thought as well looking at the code and being a natural key to use. I only have left and right arrow key functionality. My guess is that your IF statements checking the Key() function for two different values is the problem. (guess)

Code: OxygenBasic

ELSE IF SW_Key(32) AND SW_Key(37) AND zRak = 0 THEN 
 

How can the return of your Key() function be equal to 32 & 37 at the same time?

JRS · « **Reply #7 on:** March 17, 2013, 09:55:02 AM »

Here is the code for the game in ScriptBasic if you want to give it a try and maybe figure out why I only have left and right arrow keyboard support.

I had mentioned this with the SokoMouse game and I see you didn't get the hint. The CPU takes a big hit if you do a SetFps() call in the WHILE/WEND loop. It only needs to be set ONCE to keep the frame rate at the desired value.

FYI If I remark out the SetFps(), SB is runs at 150+ FPS in a XP VirtualBox. (on top of Ubuntu 64)

JRS · « **Reply #8 on:** March 17, 2013, 11:03:14 AM »

Once again, DO NOT use scribaw.exe with anything other than IUP GUI scripts. PLEASE use scriba.exe from the console command line. Make sure the path to the SB bin directory is set and DLLC.dll is in the modules directory.

This updated attachment reflects the changes I made to BS.sbx (main game script) and includes the most recent dllc.dll file.

Update

Like SokoMouse, using SetFPS(60) outside the WHILE/WEND loop and using Sync() rather than Redraw() gives me the best game play. (Frames average around 90 in the title bar) It reduces CPU usage by 75% without changing the anything with the game.

Peter,

I think you will find the root of our problems if you realize all variables return undef until assigned. I had to add zFrame = 0 to SetData as it was calling Simple Windows with it set as undef causing a GPF. If you can look at the code and determine what absolutely must be initialized prior to use we may find the problem. In the O2 version DIMing the arrarys must initialize them to zero.

Quote

Another thing is SW_RAND, dosn't work like Simple Window RND.

SW_Rnd is a wrapper for your Simple Windows API function and used in both SokoMouse and Angry Birds II. The ScriptBasic version of RND() isn't compatible with yours but is a SB keyword and SW_Rnd() is what your random generator function is calling in the games.

John

P.S. Hope you're not living in a Starbucks if you weren't kidding about the house burning down.

JRS · « **Reply #10 on:** March 17, 2013, 03:14:36 PM »

I put the following in the WHILE/WEND loop and it printed fine when pressing the space bar.

Code: [Select]

  IF SW_Key(32) THEN PRINT "Space Key\n"

It seems, there is a bug in ScriptBasic! I changed (zFrame = zFrame +1) in (zFrame +=1) and then there was animation!

Your observation made me curious so I wrote a little program to test your theory.

Code: [Select]

a += 1
PRINT "A: ",a,"\n"

b = b + 1
PRINT "B: ",b,"\n"

c = 0
c += 1
PRINT "C: ",c,"\n"

d = 0
d = d + 1
PRINT "D: ",d,"\n"

C:\SB22\test>scriba plusone.sb
A: 1
B: undef
C: 1
D: 1

C:\SB22\test>

It seems your right about there is a different result if referencing an uninitialized variable and then incrementing it. It seems to work correctly either way if the variable is assigned (initialized) before hand.

Thanks for pointing this out!

JRS · « **Reply #12 on:** March 17, 2013, 09:05:05 PM »

Peter,

I was right about the initialization of variables for this game. Add this SUB to the top of the program and call it in Main before starting. Everything seems to be working except using the Windows MM API for playing the wave is causing delays. I'm assuming the Bass call lets the game continue and plays the sound in another thread?

ScriptBasic may be doing exactly as its told. There is a difference between incrementing an uninitialized variable and adding 1 to it.

Code: OxygenBasic

a += 1
PRINT "A: ",a,"\n"
 
b = b + 1
PRINT "B: ",b,"\n"
 
c = 0
c += 1
PRINT "C: ",c,"\n"
 
d = 0
d = d + 1
PRINT "D: ",d,"\n"
 
undef u
PRINT "U: ",u + 1,"\n"
 

C:\SB22\test>scriba plusone.sb
A: 1
B: undef
C: 1
D: 1
U: undef

C:\SB22\test>

ScriptBasic defaults to careful but lazy programmer mode as default.

You have the option to tell SB that you want some warning (errors) that you forgot an assignment and how you want SB to react to undef in expressions. Setting Options

Quote from: SB Docs

BASIC languages generally do not require variable declaration to be programmer friendly. ScriptBasic is no exception for compatibility reasons: you can write huge programs without declaring any variable. Although this is possible this is not a good practice. Programmers can easily mistype a variable name and end up getting a new variable with undef value instead of getting compilation error. This may cost a lot of debugging time.

Forcing Variable Declaration

Another cool SB feature is switching between TEXT or BINARY mode on the fly with STDIN/OUT operations.

Switching between binary and text mode
