Same here squidgetx :) Unless i was absolutely forced to use nibble maps, i would go full byte every time ^^

Thanks ;) That little bit of support has now convinced me to change it around. Ironically this will lessen the amount of free RAM I need since I will be changing map sizes from 100x100 to 50x50, and even with the change from nibbles to bytes that still means we're going from 5000 bytes per map to 2500 :)

edit: actually maybe I'll make it 64x64 instead...

yeah powers of 2 make things a lot faster and simpler in some of the tile detection code

About preserving the back-buffer: there are 3 saferam areas designated for saving the screen. They are plotSScreen (default buffer used w/ drawing bcalls, also is the buffer in Axe, L6), appBackUpScreen (back-buffer in Axe, L3), and saveSScreen (L1 in Axe). This is obviously all well and good, but Quigibo used the first 56 bytes for the A-Z+THETA vars. If you don't mind overwriting those, or don't mind adding free mem in-program to use as vars, you can use saveSScreen as a backup-back-buffer (it's L1-56).

I'm trying to figure out how best to RLE my maps for an upcoming game of mine, since I have little motivation to work on HL2.  Any suggestions?  The maps could get quite large, and tilemapping should be fast.

RLE? HL2? (Sorry, I'm bad with acronyms)

Thanks calcdude. Here would be my suggestion for RLE, (I'll refer to the leftmost bit as bit 7), bit 7 will be 0 if that byte will include the data, or 1 if the next byte will give the length.

Didn't Nemo write a compression/decompression routine for tilemaps? You might want to ask him or run a search on the forums to see if you can find it. Maybe he just had compression, though.
* DJ Omnimaga thinks this is when we need a !call function on the forums.

Ah, right, decompression was done, too. I wasn't sure anymore. :)

Okay, I'm having a problem with one.
It has a few display glitches...
Still can't figure out the tilemapper though.
When scrolling both horizontally and vertically, there's display issues.
To test: make a tio level using any of the versions, then run this.  It uses the Tio map for data.


attached is (non-playable) level that really shows the graphical problems...yay :P

EDIT have some code

Ok, that's been taken care of since, and I have a pretty good idea of how it works.
A random idea I got was to make simply written, heavily commented source code, so other people can learn from them.
So far, I have basic 8*8 tilemapping (no scrolling) covered.

Quick question: there's a type of scrolling, not smoothscrolling, but it scrolls like 8 pixels at a time.  Kind of like, say, pyyrix did scrolling.  What's that called?

btw yes, i'm still working on Tio, I'm just trying to learn more on how to do this so i don't screw up big time then i try to add it.
