New page

Vicky II support 8 tilesets and 4 tilemaps.

=== Tiles ===
Tiles are tiny reusable bitmaps that are 16 pixels wide by 16 pixels high.

=== Tilesets ===
Tiles are combined in tilesets. Tilesets usually contain only unique tiles to save memory. Tilesets can contain a maximum of 256 tiles. Each tile has a unique number in the tileset.
Tilesets must be stored in video RAM for Vicky II to be able to render them.

=== Tilemaps ===
Tilemaps combine tiles from the tilesets to create a world map. Tilemaps can be up to 1024 tiles wide by 1024 tiles high.
Tilemaps must be stored in video RAM in order for Vicky II to render them.

== Tilemap Registers ==

Each Tilemap has registers composed of a total of 12 bytes for manipulation, starting at $AF:0200 and spanning through to $AF:022F.

The first set of sprite manipulation registers are shown below:

{| {{Wikitable}}

|TL0_CONTROL_REG||= $AF:0200
|-
|TL0_START_ADDY_L||= $AF:0201

|-
|TL1_CONTROL_REG || $AF:020C
|-
|TL2_CONTROL_REG || $AF:0218
|-
|TL3_CONTROL_REG || $AF:0224
|}
For each successive tilemap, add +12 to the address registers.

The tilemap control register (TLx_CONTROL_REG) is always the first byte of the 12 byte block. The register is configured as follows:

{| {{Wikitable}}
!Attribute
!Bit
|-
|TILE_Enable||= $01
|-
|TILE_Collision_On||= $40
|}

The Tilemap Total Size X and Y must be less than 1024.

The Tilemap Window Position X and Y are defined as follows:
{| {{Wikitable}}
!Attribute
!Bit
|-
|Direction|| Bit 14 ($4000)
|-
|Scroll|| Bits 10-13 ($4xx to $3Cxx)
|-
|Position||= 0 to $3FF
|}
