Troubleshooting:
----------------
Most of the problems from experience, are tring to load files from
the wrong directory. This can cause a lot of mess on the screen and
perhaps a few lock ups. Look for this problem right away.
If everything seems to be alright, read on...
Problem: When I set the palette with wsetpalette, all the colours remain
black...
Solution: You should have set the palette beforehand, with wsetrgb,
wloadpalette, or wloadsprites. If you have set the palette,
make sure the palette file was found if you are loading it in.
Problem: When using the multidirectional scrolling, my objects do not show up
on top of the background.
Solution: First, make sure the variable numsprites contains the highest
object number you are using. Second, make sure you compile
your program with word alignment OFF. To do this, set
the option under Options/Compiler/Code Generation, or
use the appropriate switch from the command line compiler.
Also make sure your object sprite file was loaded alright.
Problem: My program compiles fine, but it gives me a stack overflow error
when I run it.
Solution: Make sure you compile your program using the large memory model.
If you are using the region fill routine, type
_stklen=64000;
at the beginning of your program to make sure the fill works fine.
Problem: My program gives me an out of memory or out of heap space error.
Solution: Set the heap size under the Options/Debugger menu to a large
number. This will change how much memory Turbo C gives it
when it runs. For the maximum amount, set it to 640. This will
make sure you can run very large programs. If that doesn't
work, try running it from DOS, or cut down the memory
needed temporarily.
Problem: Some of the example files do not seem to work right, and I
must use a control break to end.
Solution: Many of the example programs require a mouse to operate.
If you do not have a mouse, you will not be able to use
that particular program. Browse through the program to see
what exactly it is looking for to continue. Sometimes
it is waiting for a keypress which you did not hit.
Problem: When I use the fade_in, fade_out, or wsetpalette functions,
the screen flickers and "snow" appears. What is happening?
Solution: This screen disturbance occurs when you set the palette entries.
There is no way to get rid of the snow completely, however
there are a few things you can do. Try setting fewer palette
entries at once, and use a larger delay if you are fading the
colours in or out.
Problem: When I display a sprite or a block on the screen, a mess
appears.
Solution: The block file or sprite file you loaded in was not found.
When you attempt to display the block or sprite, the data
in memory is undefined and it displays whatever was in
memory at that address before you ran your program.
Check to see the paths are correct in your load statements.
This error is common when you have first installed WGT
on your hard drive since it will depend on where you
copied the files. You need to change the pathnames in
any operations which load a file.
If you are still stuck, please contact WordUp Software Productions by
