lol, I love p2p networks, I got a copy of the help files for blitz which will be deleted as soon as I finnish helping you . But unfortunatly they are just grabs from the website, and probably out of date...

OK blitz is a basic language and therefor can not handle some of the more advanced stuff c can do, but a quick re-write of the way the code is written and blitz does the same thing...

So, for example, taking the last line fy -= (m_Size == 1) ? 16 : 32 this can be we-written to:

if m_Size = 1	fy = fy - 16else	fy = fy - 32end if 

or

tms = 32 shr m_size ; that''s if this bit of code works...fy = fy - tms 

ok the array map in c is defined as an array of struct _Map_Tile, and _Map_Tile is defined as :

typedef struct _Map_Tile{	BYTE  Floor;	BYTE  Height;	BYTE  Flags;	BYTE  Object;	_Map_Tile *Next;} MapTile, *pMapTile; 

and in bltiz this would be (I think) :

Type _Map_TileField Tile  ; This was Floor, but I noticed that Floor is a reserved name.Field HeightField FlagsField ObjectEnd Type 

I''m not sure how you do linked lists in Blitz, but you should look into it as this will allow you to add tiles onto the base tile, i.e your ground tile is constant and you can change the image on top of that tile to show something building for example, or add bits at different hights (like a weird shaped building being split up and put only in the right places).

ok now back to your code snippet above...

tmx = mxtmy = myts = 3 - m_Sizetms = 64 SHR m_Size ; I''m not sure if this will work...if tmx < 0 then tmx = 0if tmy < 0 then tmy = 0m = MM_LookUp( fx, fy + ( Map( tmy, tmx )\Height shl ts ), Map( tmy, tmx )\Tile )tfy = ( fy + ( Map( tmy, tmx )\Height shr ts ) )if ( fx >= 0 ) And ( tfy >= 0 ) And ( fx < tms ) And ( tfy < tms )	if ( tfy >= tms ) 		m = MM_SOUTH		TileWalk( mx, my, ISO_SOUTH )		fy = fy - ( tms shr 1 )	EndIfEndIf 

Again this code is not tested, as blitz demo keeps crashing...

When I find my code in tons of trouble,
Friends and colleages come to me,
Speaking words of wisdom:
"Write in C."

Map( tmy, tmx )\Height - height above the ground
Map( tmy, tmx )\Tile - the tile image

these are used in the map drawing function to display the correct image at the right height offset on the map.

Eh what do you mean by that?

How else would you show height in your game?
