But didn't AMS give you more freedom with the LCD buffers?

No. But LCD video memory is handled differently between the HW1 and the HW2/HW3 calcs. However, TIGCC and extgraph library make this fact completely transparent. You may see a little more flicker with the HW2/HW3 calcs.

Let me guess... You mask the 5 unused bits.

Yes, I do. I created a modified version of the GraySprite16_RPLC that masks out the 5 un-needed bits. But this is not absolutely necessary because when you draw the next tile, you physically draw it over the 5 un-needed bits.

This will be supported by AMS 3.xx plue HW3 patch, right? Will I find this on ticalc.org, TIGCC website, or the Ti Chess team website?

Yes, TIGCC and extgraph are compatible with all AMS and all HW versions. Although, I think you need to install the HW2 patch (for HW2 calcs) or the HW3 patch (for the HW3 calcs). I dont remember the reason why. extgraph can be found at the TI Chess Team website.

I've never written a tilemapper before, not even in Ti-Basic or ASM.  I know the general structure of a map is a matrix where each element represents which sprite needs to be drawn in that square.  The only thing I can't seem to write is code that reads each element of the matrix and puts the tile in the corresponding part of the screen, before going on to the next element.  I have no idea where to start.  In ASM so far, all my attempts have issues with going on to read the next element of the matrix.

I wish Ranman was here when I first started messing around with TIGCC :(sad.gif

A very simplified tilemapping routine:

c1-->
CODE
ec1

unsigned char block[8] = {0x42,0xA5,0xE7,0xFF,0x7E,0x66,0x24,0x18}; // some 8 by 8 sprite

int map[3][5] = {{1,1,1,1,1},{1,0,0,0,1},{1,1,1,1,1}}; // a map 5 units wide and 3 units tall; 1 means draw a block, 0 means draw nothing

int x, y;

for(y=0;y<3;y++) {

So this is how you instantiate a matrix.

Yep, that's it. First the num of rows, then the num of columns.

Yeah... I always thought it looked funny to get the tile using

CODE
ec1tile = tileMap[y]

68k Basic has all graphic coordinates y, x. It gets quite confusing...

in BASIC for the 83+ matrix are y,x , text commands and pixel off/test too while all others are x,y as well, confusing indeed :/

 You could also make a macro like

CODE
ec1#define GetMap(x,y) tileMap[y]
  • c2
ec2
if you want to keep x,y order ;)wink.gif.

Use TiEmu to test your games:

Whoa! I can't believe I just noticed this, but that's the exact same code used in Tifreak8x's Basic tutorial on tilemapping.

To be honest, I have to say that I use TiEmu only for real testing. Wihle I'm programming, I use VTI to look at the results because the TIGCC IDE has the "run" button for it :)smile.gif

Me too! I love the "Run" button... It is so handy.

I'm sure future versions of TIGCC IDE the "Run" button will support TiEmu.
