The lookup tables contain an additional address for a 25th character row, but this clashes with the object data and is unused. The buffer rows wrap around in memory after the 16th row, so they can fit into the program space without overlapping with screen memory or game code. The addresses are as follows: &3F00 (screenBufferRow0) &4040 (screenBufferRow1) &4180 (screenBufferRow2) &42C0 (screenBufferRow3) &4400 (screenBufferRow4) &4540 (screenBufferRow5) &4680 (screenBufferRow6) &47C0 (screenBufferRow7) &4900 (screenBufferRow8) &4A40 (screenBufferRow9) &4B80 (screenBufferRow10) &4CC0 (screenBufferRow11) &4E00 (screenBufferRow12) &4F40 (screenBufferRow13) &5080 (screenBufferRow14) &51C0 (screenBufferRow15) and then they wrap around to the following locations for rows 16 to 24: &3FA0 (screenBufferRow16) &40E0 (screenBufferRow17) &4220 (screenBufferRow18) &4360 (screenBufferRow19) &44A0 (screenBufferRow20) &45E0 (screenBufferRow21) &4720 (screenBufferRow22) &4860 (screenBufferRow23) The first batch of locations need to be able to store an entire screen row of 320 bytes, so they can be used to store the screen buffer when scrolling in any direction (and specifically for the up and down scrolling, when we need to be able to store eight full character rows in the buffer). We only need to use the second batch of locations when we are drawing the left or right buffers when scrolling sideways, or when updating an object on-screen via the screen buffer, as we then need to fit all 24 character rows into the buffer. We can fit the first 16 rows into the first batch of buffer rows, but we need more. Luckily, when scrolling sideways, each row is only eight character blocks wide, so each buffer row only needs to be 64 bytes long rather than the 320 bytes needed when scrolling up or down. This means that we are only using the first 64 bytes of each buffer, so we can stick a second batch of buffers in the latter part of each of the first batch. However, when using the screen buffer to update an on-screen object, we can't necessarily fit the entire object into the screen buffer in one go, as it could be as wide as the screen. In this case we use the full 160 bytes of each row in the screen buffer, which can contain half a screen (as half a screen is 20 character rows that takes up 160 bytes). We therefore do the object update in two stages. In other words, when the player pans up or down, we need to draw eight full-width character rows of new screen content into the screen buffers, each of which is 320 bytes. So we use the screen buffer space as follows: &3F00 to &403F for character row 0 (all 320 bytes of screenBufferRow0) &4040 to &417F for character row 1 (all 320 bytes of screenBufferRow1) &4180 to &42BF for character row 2 (all 320 bytes of screenBufferRow2) &42C0 to &43FF for character row 3 (all 320 bytes of screenBufferRow3) &4400 to &453F for character row 4 (all 320 bytes of screenBufferRow4) &4540 to &467F for character row 5 (all 320 bytes of screenBufferRow5) &4680 to &47BF for character row 6 (all 320 bytes of screenBufferRow6) &47C0 to &48FF for character row 7 (all 320 bytes of screenBufferRow7) And when the player pans left or right, the new screen content that we need to draw into the screen buffers is a strip down the side of the screen that's 24 character rows tall and eight character columns wide, so each row is 64 bytes long. So we use the screen buffer space as follows: &3F00 to &3F3F for character row 0 (first 64 bytes of screenBufferRow0) &4040 to &407F for character row 1 (first 64 bytes of screenBufferRow1) &4180 to &41BF for character row 2 (first 64 bytes of screenBufferRow2) &42C0 to &42FF for character row 3 (first 64 bytes of screenBufferRow3) &4400 to &443F for character row 4 (first 64 bytes of screenBufferRow4) &4540 to &457F for character row 5 (first 64 bytes of screenBufferRow5) &4680 to &46BF for character row 6 (first 64 bytes of screenBufferRow6) &47C0 to &47FF for character row 7 (first 64 bytes of screenBufferRow7) &4900 to &493F for character row 8 (first 64 bytes of screenBufferRow8) &4A40 to &4A7F for character row 9 (first 64 bytes of screenBufferRow9) &4B80 to &4BBF for character row 10 (first 64 bytes of screenBufferRow10) &4CC0 to &4CFF for character row 11 (first 64 bytes of screenBufferRow11) &4E00 to &4E3F for character row 12 (first 64 bytes of screenBufferRow12) &4F40 to &4F7F for character row 13 (first 64 bytes of screenBufferRow13) &5080 to &50BF for character row 14 (first 64 bytes of screenBufferRow14) &51C0 to &51FF for character row 15 (first 64 bytes of screenBufferRow15) &3FA0 to &3FDF for character row 16 (first 64 bytes of screenBufferRow16) &40E0 to &411F for character row 17 (first 64 bytes of screenBufferRow17) &4220 to &425F for character row 18 (first 64 bytes of screenBufferRow18) &4360 to &439F for character row 19 (first 64 bytes of screenBufferRow19) &44A0 to &43DF for character row 20 (first 64 bytes of screenBufferRow20) &45E0 to &461F for character row 21 (first 64 bytes of screenBufferRow21) &4720 to &475F for character row 22 (first 64 bytes of screenBufferRow22) &4860 to &489F for character row 23 (first 64 bytes of screenBufferRow23) And when we update an object on-screen that is wider than half a screen, we use 160 bytes in all 24 row buffers to draw the first 20 character columns of the object, and then we repeat the process to finish off drawing the remainder of the object. This structure ensures that the screen buffer always fits into the collection of screenBufferRow blocks, irrespective of the scrolling direction or the size of the object we're drawing..screenBufferRow16 EQUB &00, &00, &00, &00, &00, &00, &00, &00 EQUB &00, &00, &00, &00, &00, &00, &00, &00 EQUB &00, &00, &00, &00, &00, &00, &00, &00 EQUB &00, &00, &00, &00, &00, &00, &00,

(colour, drawing phase)Context: See this variable on its own page References: This variable is used as follows: * DrawObject uses objPolygonData
Polygon data is stored as follows: * Bit 7 is the phase in which to draw this polygon (0 = first phase, 1 = second phase) * Bit 6 is unused and is always clear * Bits 4-5 contain the edge colour (0 to 3) * Bits 2-3 contain the fill colour (0 to 3) * Bits 0-1 give the number of sides (0 = three sides, 1 = four sides) The individual object tables (such as objTree and objSentinel) list the points that are used to draw each polygon.[X]Subroutine DrawSights (category: Sights)Draw the sights on the screen, saving the existing screen contents in the sights pixel byte stash[X]Subroutine
