Some bug reports indicate that this is still - * happening in 2.7.8 for Windows, though it appears to be impossible. - * - * We "pre-calculate" the blast area only in part for efficiency. - * More importantly, this lets us do "explosions" from the "inside" out. - * This results in a more logical distribution of "blast" treasure. - * It also produces a better (in my opinion) animation of the explosion. - * It could be (but is not) used to have the treasure dropped by monsters - * in the middle of the explosion fall "outwards", and then be damaged by - * the blast as it spreads outwards towards the treasure drop location. - * - * Walls and doors are included in the blast area, so that they can be - * "burned" or "melted" in later versions. - * - * This algorithm is intended to maximize simplicity, not necessarily - * efficiency, since this function is not a bottleneck in the code. - * - * We apply the blast effect from ground zero outwards, in several passes, - * first affecting features, then objects, then monsters, then the player. - * This allows walls to be removed before checking the object or monster - * in the wall, and protects objects which are dropped by monsters killed - * in the blast, and allows the player to see all affects before he is - * killed or teleported away. The semantics of this method are open to - * various interpretations, but they seem to work well in practice. - * - * We process the blast area from ground-zero outwards to allow for better - * distribution of treasure dropped by monsters, and because it provides a - * pleasing visual effect at low cost. - * - * Note that the damage done by "ball" explosions decreases with distance. - * This decrease is rapid, grids at radius "dist" take "1/dist" damage. - * - * Notice the "napalm" effect of "beam" weapons. First they "project" to - * the target, and then the damage "flows" along this beam of destruction. - * The damage at every grid is the same as at the "center" of a "ball" - * explosion, since the "beam" grids are treated as if they ARE at the - * center of a "ball" explosion. - * - * Currently, specifying "beam" plus "ball" means that locations which are - * covered by the initial "beam", and also covered by the final "ball", except - * for the final grid (the epicenter of the ball), will be "hit twice", once - * by the initial beam, and once by the exploding ball. For the grid right - * next to the epicenter, this results in 150% damage being done. The center - * does not have this problem, for the same reason the final grid in a "beam" - * plus "bolt" does not -- it is explicitly removed. Simply removing "beam" - * grids which are covered by the "ball" will NOT work, as then they will - * receive LESS damage than they should. Do not combine "beam" with "ball". - * - * The array "gy[],gx[]" with current size "grids" is used to hold the - * collected locations of all grids in the "blast area" plus "beam path". - * - * Note the rather complex usage of the "gm[]" array. First, gm[0] is always - * zero. Second, for N>1, gm[N] is always the index (in gy[],gx[]) of the - * first blast grid (see above) with radius "N" from the blast center. Note - * that only the first gm[1] grids in the blast area thus take full damage. - * Also, note that gm[rad+1] is always equal to "grids", which is the total - * number of blast grids. - * - * Note that once the projection is complete, (y2,x2) holds the final location - * of bolts/beams, and the "epicenter" of balls. - * - * Note also that "rad" specifies the "inclusive" radius of projection blast, - * so that a "rad" of "one" actually covers 5 or 9 grids, depending on the - * implementation of the "distance" function. Also, a bolt can be properly - * viewed as a "ball" with a "rad" of "zero". - * - * Note that if no "target" is reached before the beam/bolt/ball travels the - * maximum distance allowed (MAX_RANGE), no "blast" will be induced. This - * may be relevant even for bolts, since they have a "1x1" mini-blast. - * - * Note that for consistency, we "pretend" that the bolt actually takes "time" - * to move from point A to point B, even if the player cannot see part of the - * projection path. Note that in general, the player will *always* see part - * of the path, since it either starts at the player or ends on the player. - * - * Hack -- we assume that every "projection" is "self-illuminating". - * - * Hack -- when only a single monster is affected, we automatically track - * (and recall) that monster, unless "PROJECT_JUMP" is used. - * - * Note that all projections now "explode" at their final destination, even - * if they were being projected at a more distant destination. This means - * that "ball" spells will *always* explode. - * - * Note that we must call "handle_stuff()" after affecting terrain features - * in the blast radius, in case the "illumination" of the grid was changed, - * and "update_view()" and "update_monsters()" need to be called. - */ -bool_ project(int who, int rad, int y, int x, int dam, int typ, int flg) -{ - int i, t, dist; - - int y1, x1; - int y2, x2; - - int dist_hack = 0; - - int y_saver, x_saver; /* For reflecting monsters */ - - int msec = delay_factor * delay_factor * delay_factor; - - /* Assume the player sees nothing */ - bool_ notice = FALSE; - - /* Assume the player has seen nothing */ - bool_ visual = FALSE; - - /* Assume the player has seen no blast grids */ - bool_ drawn = FALSE; - - /* Is the player blind? */ - bool_ blind = (p_ptr->blind ?
