You might mean 01.
And no, since you subtract 1 from the sprite number, the 1 is 0 and so on.

No. 01 would be

Hmmm...
You can just play around with this code, throw it in a repeat getKey(15) loop, and add Dispgraph:ClrDraw after it. You can for example change numbers in the map (Create some sprites before and put them in Pic1).
Or try to figure out how to draw a 5x4 map instead of a 4x4. The possibilities are endless.
(if you really want I will create a program but not now since I am a bit tired)

ok.
Wait, I made a stupid mistake

Code: [Select]

T--
If T

should be

Code: (fixed) [Select]

if T
T--

{B*4 ; B is the row number counted from zero, 4 is the width of a row
+A ; A is the column number (sorry for being wrong there)
{B*4+A ;gets the tile number counted from upper left.
+GDB1} ;GDB1 is the pointer to the tilemap.
->T ;store the number that this returns in T
If T ; only draw a tile when T is not zero (zero means no sprite)
T-- ;subtract one from T to get the tile number
pt-on(a*8,B*8, ;draws the sprite at a*8,b*8
T*8 ;multiplies T by 8 since one sprite is 8 bytes
+Pic1 ;Pointer to sprite data

I hope it is clear now

T-- ;subtracts one from T so you do not have to draw

A for loop repeats until the variable specified reaches the second number (it adds one to the variable each time a loop is ran)
For(variable, start, stop)
so for(a,0,3) will loop from a = 0 to a = 3. The best thing is that you can access the variable inside the loop.

Okay, very quick (basically commented code): Say what part you don't get.

Code: [Select]

[01010101]->GDB1   ;this is the tilemap in hexadecimal code.
[01000001]
[01010001]
[01000001]
(Some sprite data to pic1 here)
for(b,0,3)   ;outer loop for drawing the different columns
for(a,0,3)   ;inner loop for drawing the rows
{B*4+A+GDB1}->T  ;gets the tile number minus 1 to T 
if T ;checks if a tile should be drawn
T--
pt-on(a*8,b*8,T*8+pic1)   ;draw the tile
end
end
end

That are the basics of the tilemap drawing code.
