Hi, this is my code for determining the tile (8x8 pixels) the player is on. Basically what I am trying to do is (x + y * 32), so that later I can look it up in the tiles array (.db)

I am not sure if ASL (five times would be the same as * 32).

CalcTargetTileNumber:

  LDA player_tile_y
  ASL A ; multiple by 32?
  ASL A
  ASL A
  ASL A
  ASL A
  CLC
  ADC player_tile_x_w
  STA target_tile_number

  RTS

This is your second third! thread with a specific programming question. This is exactly why I made this thread right here:

Please start using it and not using individual threads for each question. This will allow us to better keep things organized.

Thank you.
