Move your tiles +**1. Move your tiles** First you need to know that the font tileset (in gfx/font/font.png) is used in battle just like the 2 attack animation tilesets. If you look at this font tileset, you will notice a white empty space (enough for 32 tiles) right after the 64 characters, BUT this space can't be used for the tiles that use 4 colors. The font tileset is coded in 1 bit per pixel (1bpp), which means that it only uses black (and white for the transparency of course). No gray. Now the interesting thing is that many tiles in the attack tilesets (22 in total) only use black. So, as you probably want to add 4-color tiles, you can just move the black tiles from the attack tilesets to the unused space in the font tileset, and then replace these black tiles by your custom tiles. -2. Change the tile IDs in frameblocks +**2. Change the tile IDs in frameblocks** From this point, it's a bit complicated to explain but I will do my best and show an example. So, after moving your tiles, change the tile IDs in the frameblocks so that the animations find the new location of the moved tiles. Otherwise, the attacks using these tiles will not find them (they would use the new replaced tiles and that's not what we want). Just change data/battle_anims/frame_blocks.asm. @@ -22,7 +22,7 @@ You need to do a little bit of investigation for that, I mean you need to find w Important to know: the font tileset can be used along with attack_anim_1 or attack_anim_2 (and even attack_anim_3 if you add a 3rd tileset).

When you set the tileset ID of an animation to 3, this causes a bug as soon as you use your new tileset (if FIRST_SE_ID is left to 0xC0). The bug comes from the PlayAnimation routine in engine/battle/animations.asm. |
