示例1: check_captures
int check_captures(position src, position dst, board const& board,
piece what, OutIter out) {
piece::color_t const player = what.color();
board::mask supporters;
int score = 0;
if (trap(dst)) {
supporters = neighbourhood(dst) & board.player(player);
supporters[src] = false;
// Check for piece stepping into a trap.
if (supporters.empty()) {
*out++ = elementary_step::make_capture(dst, what);
score -= CAPTURE_COEF * cost(what, src);
}
}
// Check for piece abandoning another one standing on a trap.
if (neighbourhood(src) & board::mask::TRAPS && !trap(dst)) {
position const trap =
(neighbourhood(src) & board::mask::TRAPS).first_set();
