I'm looking to code it for a microcontroller, so I don't get to use linked lists.
I guess this means I use an array of x,y coords for segment positions.

I figure this: cell = cellTail while cell ~= cellHead do if cell.x == lastX and cell.y == lastY then gameOver = true break end cell = cell.next end code checking for an end game condition is like a next...for loop. So the game must be keeping an array of coordinates of old snake heads.

Shine's Lowser Snake Game

Hi Guys, I'm trying to understand, and recode the way Shine's Snake game works. I have a rough idea how to follow it, but have some questions. How is it determined where the last segment of the snake is (the tail segment that is removed)? Also, pretty much the same question, since the answer to any ...

Well thanks for the tip,
I didn't think of that.
I ended up bypassing it for longer messages.
The program first looks for a text file to use,
and opens the OSK if the text file isn't present.

OSK 50 Char Limit?

Hi Guys, I built a 144 LED scrolling message display: http://www.youtube.com/watch?v=qFKy60IF3Tg It's message data is compiled by a PSP program that converts a message string input through the OSK to a monochrome bitmap in the correct format to be written to the EEPROM in my LED circuit. The monochr...

Like I said, I started from the last source code backup that didn't have the problem
(rather than actually solve it) then started again from there.
I do remember that, at the time, I wasn't doing anything related to graphics/screen drawing to cause the problem, so I was stumped at the time too.

By starting again from the last properly working backup source code.

Maybe the JGE code isn't causing trouble, maybe the JGE engine has the problem.
But the problem def isn't only occuring with JGE programs.
I've seen the same complaint on this forum from someone else before too.

Slim extra memory Question

Hi,
If you set the extra memory flag in the make file to use the slim RAM,
will the program fail to load on a PSP1000 straight away even if the extra RAM was not used?

If not, when will the program fail to load on a PSP1000... when a 40Mb array is defined, or when you go to use it?

Well the delay didn't help. It crashes in the same place. Yes it stops ten seconds or so before powering off.

Thanks for the replies guys.
I have a feeling the length of time spent in a while loop is causing it
because it's crashing when the array is larger, and execution is hanging
around in a while loop longer.

I'll try the delay first up since it seems to fit.
