27211 LD HL,32548 HL=PlayerSpriteTable.
27214 LD C,A Create an offset in BC.
27215 LD B,0
27217 ADD HL,BC HL=PlayerSpriteTable + offset.
27218 LD E,(HL) DE=pointer to the player sprite for this direction.
27219 INC HL
27220 LD D,(HL)
The player is drawn statically in the centre of the play area.
27221 LD HL,20371 HL=20371 (screen location).
The player sprite is 2 bytes in width.
27224 LD A,2 Write 2 to WidthCounter.
27226 LD (24108),A
27229 LD A,(DE) A=height of the sprite in pixels.
27230 INC DE Increment DE by one to point to the sprite data.
27231 LD C,A C=A (height of the sprite).
DrawPlayer_NextRow 27232 LD A,(24108) B=WidthCounter.
27235 LD B,A
27236 PUSH HL Push HL on the stack.
DrawPlayer_NextCol 27237 LD A,(DE) Copy a byte from DE (the player sprite data) to HL (the screen position).
27238 LD (HL),A
27239 INC DE Increment DE (the player sprite data pointer) by one.
27240 INC L Increment L by one, this moves onto the next adjacent screen byte.
27241 DJNZ DrawPlayer_NextCol Decrease counter by one and loop back to DrawPlayer_NextCol until counter is zero.
27243 POP HL Restore HL from the stack.
27244 CALL ScreenPos1PixelAbove Call ScreenPos1PixelAbove.
