^^ this is the "sync engine" of our bp demo. the first line actually optional, so it's really one line!

Code: return $success ? true : false


I just encountered this beauty in some code here (at the place I work).

Yes, web development is soul destroying.

Dunno why, but that should have been BACKSLASHnBACKSLASHt and not just nt behind the ASM lines.
spinor: optimize it to "!!$success"!.

@ryg: When I did some c (some hundred years ago) I also used the double negation until I discovered that the WATCOM compiler removed them in optimization to (success == !!success). I probably spend some hours figuring that out. Actually I like the idea, that nowadays others struggle for me with C++ and I can relax programming python.

Greets to blala for haskell-demos. I'd like to see more democoders using very high-level languages, and I really liked your breakpoint08 entry with the impossible-to-remember name.

ah, thanks. the trick is to remember "mrs. pavlov" only, and then the pouet search tells you the rest :)

Probably the most embarassing code I have written for long:
Code: public void move() { Direction d = next_move; int pri_coord; float pri_sub, sec_sub; int dir_sign; next_move = Direction.NONE; switch(d) { case UP: case DOWN: pri_coord = y; pri_sub = y_sub; sec_sub = x_sub; dir_sign = d.y; break; case LEFT: case RIGHT: pri_coord = x; pri_sub = x_sub; sec_sub = y_sub; dir_sign = d.x; break; default: return; } if (!map.coordsAreWithin(x + d.x, y + d.y)) return; if (!map.tileOn(x + d.x, y + d.y).isTraversable()) { pri_sub += speed * dir_sign; if(pri_sub * dir_sign > 0) { pri_sub = 0; } } else { if (pri_sub != 0.0f) { if (speed < Math.abs(pri_sub)) { if (pri_sub < 0) { pri_sub += speed; } else { pri_sub -= speed; } } else { pri_sub += (speed - Math.abs(sec_sub)) * dir_sign; sec_sub = 0; } } else { pri_sub += speed * dir_sign; } } if (pri_sub * dir_sign > 1.0f) { pri_coord += 1 * dir_sign; pri_sub -= 1.0f * dir_sign; } switch(d) { case UP: case DOWN: y = pri_coord; y_sub = pri_sub; x_sub = sec_sub; break; case LEFT: case RIGHT: x = pri_coord; x_sub = pri_sub; y_sub = sec_sub; break; } }

Trying to shorten this:
Code: private void moveY(int sign) { if (!map.coordsAreWithin(x, y - 1 * sign)) return; if (!map.tileOn(x, y - 1 * sign).isTraversable()) { y_sub -= speed * sign; if (y_sub * sign < 0) { y_sub = 0; } } else { if (x_sub != 0.0f) { if (speed < Math.abs(x_sub)) { if (x_sub < 0) { x_sub += speed; } else { x_sub -= speed; } } else { y_sub -= (speed - Math.abs(x_sub)) * sign; x_sub = 0; } } else { y_sub -= speed * sign; } } if (y_sub * sign < 1.0f) { y -= 1 * sign; y_sub += 1.0f * sign; } } private void moveX(int sign) { if (!map.coordsAreWithin(x - 1 * sign, y)) return; if (!map.tileOn(x - 1 * sign, y).isTraversable()) { x_sub -= speed * sign; if (x_sub * sign < 0) x_sub = 0; } else { if (y_sub != 0.0f) { if (speed < Math.abs(y_sub)) { if (y_sub < 0) y_sub += speed; else y_sub -= speed; } else { x_sub -= (speed - Math.abs(y_sub)) * sign; y_sub = 0; } } else x_sub -= speed * sign; } if (x_sub * sign < 1.0f) { x -= 1 * sign; x_sub += 1.0f * sign; } } public void move() { switch (next_move) { case LEFT: moveX(1); break; case RIGHT: moveX(-1); break; case UP: moveY(1); break; case DOWN: moveY(-1); break; } next_move = Direction.NONE; }

It's for a Bomberman game, and it is the movement code.
