§Ternary logic
Compute “ternary logic” using an 8-entry lookup table.
For each bit, the expression will be computed as:
a | b | c | lut |
|---|---|---|---|
0 | 0 | 0 | lut & (1 << 0) != 0 |
0 | 0 | 1 | lut & (1 << 1) != 0 |
0 | 1 | 0 | lut & (1 << 2) != 0 |
0 | 1 | 1 | lut & (1 << 3) != 0 |
1 | 0 | 0 | lut & (1 << 4) != 0 |
1 | 0 | 1 | lut & (1 << 5) != 0 |
1 | 1 | 0 | lut & (1 << 6) != 0 |
1 | 1 | 1 | lut & (1 << 7) != 0 |
§Example
// if sprite_mask { background } else { sprite }
background.ternlog(sprite, sprite_mask, 0xe4)Traits§
