Just wondering how many Retro Remake forum regulars are here now?  I've seen one or two new names here in GLB land that I recognise

The ability to assign a default value to a type works for functions when it is in the main (first) GBAS file, but if you declare in an additional file you get an error.

Try this code:

Code (glbasic) Select Expand

TYPE TEST
t = RGB(255,255,255)
ENDTYPE


First in the main file, it will compile, then add a second file to your GLB project and move it in there.  I get this error (on V7 RC2):

My game won't run when in Debug mode since I updated GLB to the build 6.184.  In release mode it works - just not in debug mode.

In Debug mode it will just exit without an error.  I've tracked it down to this line ...

IF SPLITSTR( strLine$, st$[], ",") = 7

which has the following in strLine$:

20,FIRE BUTTON INCREASES SPEED,FEUER-KNOPF BESCHLEUNIGT,APPUYEZ LE BOUTON FEU POUR AUGMENTER LA RAPIDITE,JOYSTICKKNAPPEN ÖKAR HASTIGHETEN,jmnoj` ncm) sbekhwhb`er qjnpnqr|,SKYTE KNAPPEN GJØR DET RASKERE

st$[] contains 7 elements (0 to 6) from the previous loop (this is in a loop that has run so far for 19 iterations each with different data in the strLine$ variable).


It was working in the previous build in Debug and Release mode.

Hi Gernot

Could I request two teeny additional features for GLB in the editor and compiler to be added to the wish list?

First one is could you add a strict option in GLB to fail compilation with an error instead of a warning when a variable has not been declared.  Make this an option that is off by default so not to cause any compatibility problems with older code and those that don't want it.  See reasons why below.

Second one is could you add an option to the editor to not change the case of what you type when it detects a reserved word.  And add a button to reformat the current code window (force case, spacing, indenting etc) so you can tidy up your code when you need to.  I know some people will like it, so again as an option, but for me it tends to get in the way.  The colour coding is not a problem (and is helpful) but the change to UPPERCASE changes your program.



The reason for the two above requests are that often, while in a procedure for example, I declare a local variable that starts with a reserved word, such as MAX for example, often GLB will jump in and change that part to upper case.  For example if I have a variable called "maxt" it I press del key to remove the 't' then max becomes MAX.  If I leave it as-is, and now have a new variable called MAXt, a different variable to maxt.  See code below.

Example:
FUNCTION test1:
   LOCAL maxt
   maxt=0
   MAXt=1
   
   PRINT maxt + " " + MAXt,0,0
   SHOWSCREEN
   KEYWAIT
ENDFUNCTION

in the compilation log (but only when in debug mode):
"test.gbas"(4) warning : implicitly created GLOBAL  : MAXt


The output from the above is "0 1" because we've now got two different variables.  If you have debug mode off you don't even see the warnings.

Would it be possible to add these features?  The strict option would stop any errors being introduced and if we could turn off auto formatting we could avoid the annoying renaming (by change to uppercase) of variables when we don't want them to.  It's a pain to avoid every reserved word as part of a variable name or to retyping in lowercase.

Hi Gernot,

Any idea what's causing this error (I have the latest patch).

There's no indication if it's in my source and as it happens on linking could it be something in GLB?

WENDBy default, the alpha channel on the red circle is ignored.  If shows a solid circle.  Hold 1 on the keyboard to apply the alphamode of -1 and the alpha channel works.  Is this correct or should alphamode 0 also work?

Hi all

Is there any way to make glow effects in GLB?

What I'd normally do is use an alpha channel and additive blending.  I don't think GLB can currently load graphics with alpha channels?

I've tried alphamode 0.1 -> 1.0 with a variety of graphics but I'm not able to find anything that works for me.

I also found this (scroll down to Gernot's post) which looks interesting over at RR, but I can't seem to get it to work.

Any suggestions (and code examples)?

Would it be possible for GLB to support TRY ... CATCH blocks and THROW functionality for handling unexpected and expected errors?

This is not generally something you see in traditional BASIC's but you do get in most modern langauges (including VB) because it can help you to manage runtime errors quite easily.

All other platforms seem to be OK.

I have a project with many source files.

I referred to two variables x and y which did not exist, I should have referred to something different.  GLB's compiler correctly warned me that these will be globals however it reported the wrong file and line number which made tracking down where I'd made the mistake frustratingly hard.

Here's the message it gave me:

*** Configuration: WIN32 ***
precompiling:
GPC - GLBasic Precompiler V.2008.073 - 3D, NET
"Languages.gbas"(31) warning : implicitly created GLOBAL  : x
"Languages.gbas"(31) warning : implicitly created GLOBAL  : y

Languages.gbas is another file, and line 31 is the last line of that file.  Can this be corrected?

Hi - could anyone with a Gp2X help confirm what some of the buttons are:

Buttonlayout for GP2X:
Button4 = TAT
Button9 = FL
Button10= FR


TAT?

FL/FR are those the left and right shoulder buttons?

Thought I'd post this in case it is of any use to someone.  A snippet of code from my game where I handle mouse, joystick and keyboard inputs.  Tested on PC and PocketPC so far, the plan would be to refine it more as I get to test it on Mac / Linux and GP2X devices.  For the PocketPC side, it omits the tests that really slows the PPC down (I was loosing up to 10 frames per second testing for joystick or keys that do not exist on the PPC).

If I move the Jumps/Files/Web/Debug to the left side of the editor it does not remember the position next time I open GL Basic.  Can this be saved please

If you do not have the Jumps tab showing on the sidebar, then any functions you create will not get the syntax highlighting until you select the Jumps tab and then click back in to the text editor.

Just an annoyance, but gets more so when you have more than one source code file in the Files tab in the sidebar, you have to go between them all for all of them to be recognised.

Could the Jumps tab be updated when you are working in the text editor when the Jumps tab is not visible?

There's no DATA statement in GLB is there?  (unless I've missed them).

Would be handy to have them so I can embed some data in the code and load/create TYPE'd arrays without having to store in an external file and load it in.

Hi Gernot

Is there any reason why KEY() and GETJOY...() commands are slow on the Pocket PC?

I'm finding in my game, with a fair bit going on graphically I can get 28 FPS on my slowest Pocket PC.  If I do a "IF KEY(57) OR KEY(28)" twice in the game loop, I loose 2 FPS.  If I do "IF KEY(203) OR KEY(205) OR KEY(200) OR KEY(208)" I loose 1 FPS.  Finally if I do:

Code (glbasic) Select Expand

xx=GETJOYX(0)
yy=GETJOYY(0)
FOR i=0 TO 3
IF GETJOYBUTTON(0,i) THEN ff=1
NEXTI loose a lot.  With all the above tests it goes from 28 FPS down to 15 FPS.  Seems a steep drop.  I get the best improvement if I take the Joystick tests out.  I don't think the PocketPC is returning any values back from this anyway as the PPC's joypad+buttons seem to be detectable by keys only.  Doing the keyboard tests only (the cursor keys and fire) brings the FPS down to 22.

Can the speed of this be improved?

Windows versions run fine.  I'd assume that GP2X is running fine too as there's a quite a few people owing one here and no one has brought it up before.

I'm having problems loading in the translated text for my game via a file.

I've basically got a comma separated list where each line contains a translation of each word or sentence.

eg:

4,OPTIONS,EINSTELLUNGEN,OPTIONS,INSTÄLLNINGAR,ОПЦИИ


In my code I want to load these in:

Code (glbasic) Select Expand

WHILE ENDOFFILE(1) = FALSE
READLINE 1,strLine$However I'm having problems.  I've converted my text file to UTF-8 and this lets me load it in (I think the default was a unicode format and READLINE returned nothing).  However a conversion is done - this is what I see in the debugger:



The Swedish text has changed the Ä.  I'm not tried the Russian text- I'm hoping once I have the Russian font loaded it will display the correct characters.

How can I load this text in without loosing the characters?

Just posted this in another forum, after adding the extra characters at the bottom (it used to be 16x8 cells, now 16x16).  The size of each character is 9x9 pixels.  I've doubled the height of the image, and then added the additional characters in the bottom half.

However when I load the font in and print, it comes out all garbled.  Looks like two characters are being picked for each letter so it's still being treated as a 16x8 grid instead of a 16x16 grid?  Can you let me know what I need to change to make this font work correctly please.

When you do the manual update and click the start button, the button remains active.  While it's downloading if you click it again by accident it tries to download another and crashes.
