Replace hardcoded temp buffer sizes with a named constant Constants.h will house constants like the screen size and others. But basically only the screen size for now. Now we don't have to type that "4 bytes per 40 chars (whole screen)" comment everywhere... 2021-09-13 06:39:07 +02:00			`#ifndef CONSTANTS_H`

Fix `SCREEN_HEIGHT_PIXELS` being wrong constant Whoops. 2021-10-01 18:35:28 +02:00			`#define SCREEN_HEIGHT_PIXELS (SCREEN_HEIGHT_TILES * 8)`

Remove `vmult` lookup tables There's really no need to put the y-multiplication in a lookup table. The compiler will optimize the multiplication better than putting it in a lookup table will. To improve readability and to hardcode things less, the new SCREEN_WIDTH_TILES and SCREEN_HEIGHT_TILES constant names are used, as well as adding a new TILE_IDX macro to calculate the index of a tile in a concatenated-rows (row-major in formal parlance) array. Also, tile numbers are stored in a temporary variable to improve readability as well (no more copy-pasting `contents[i + vmult[j]]` over and over again). 2021-09-25 01:37:27 +02:00			`#define TILE_IDX(x, y) (x + y * SCREEN_WIDTH_TILES)`
