enum TileContext |
Context for tile accesses.

enum TileLayoutFlags |
Flags to enable register usage in sprite layouts.
Enumerator | |
---|---|
TLF_DODRAW | Only draw sprite if value of register TileLayoutRegisters::dodraw is non-zero. |
TLF_SPRITE | Add signed offset to sprite from register TileLayoutRegisters::sprite. |
TLF_PALETTE | Add signed offset to palette from register TileLayoutRegisters::palette. |
TLF_CUSTOM_PALETTE | Palette is from Action 1 (moved to SPRITE_MODIFIER_CUSTOM_SPRITE in palette during loading). |
TLF_BB_XY_OFFSET | Add signed offset to bounding box X and Y positions from register TileLayoutRegisters::delta.parent[0..1]. |
TLF_BB_Z_OFFSET | Add signed offset to bounding box Z positions from register TileLayoutRegisters::delta.parent[2]. |
TLF_CHILD_X_OFFSET | Add signed offset to child sprite X positions from register TileLayoutRegisters::delta.child[0]. |
TLF_CHILD_Y_OFFSET | Add signed offset to child sprite Y positions from register TileLayoutRegisters::delta.child[1]. |
TLF_SPRITE_VAR10 | Resolve sprite with a specific value in variable 10. |
TLF_PALETTE_VAR10 | Resolve palette with a specific value in variable 10. |
TLF_KNOWN_FLAGS | Known flags. Any unknown set flag will disable the GRF. |
TLF_DRAWING_FLAGS | Flags which are still required after loading the GRF. |
TLF_NON_GROUND_FLAGS | Flags which do not work for the (first) ground sprite. |
TLF_VAR10_FLAGS | Flags which refer to using multiple action-1-2-3 chains. |
TLF_SPRITE_REG_FLAGS | Flags which require resolving the action-1-2-3 chain for the sprite, even if it is no action-1 sprite. |
TLF_PALETTE_REG_FLAGS | Flags which require resolving the action-1-2-3 chain for the palette, even if it is no action-1 palette. |
