https://bbs.mountblade.com.cn/thread-2092590-1-1.html新版血条看这个，优化了刷新需要的算力，并就高频刷新导致血条消失的问题作了修补。

由于老滚老环寿司神原这样，能够显示敌方血条的第三人称动作游戏我玩了很多，所以一直想给boss安个血条，今天终于得偿所愿做了个简单的血条。代码分享在下面，用的方法比较简单粗暴，贻笑大方了。
首先是最表层的mission_tamplate，将以下代码和那一串common_battle_XXXX = 并列：
common_boss_battle_lifebar = (
  0, 0, ti_once, [
   (call_script, "script_get_boss"),
   (assign, ":cur_boss_1", reg1),
   (assign, ":distance", reg4),

   (assign, ":show_or_not", 0),

   (try_for_agents, ":agent_no"),
      (gt, ":cur_boss_1", 0),
      (agent_get_troop_id, ":troop_no", ":agent_no"),
      (eq, ":troop_no", ":cur_boss_1"),
      (agent_is_alive, ":agent_no"),
      (agent_get_position, pos1, ":agent_no"),

      (get_player_agent_no, ":player_no"),
      (agent_get_position, pos2, ":player_no"),
      (get_distance_between_positions_in_meters, ":cur_distance", pos1, pos2),

      (le, ":cur_distance", ":distance"),                            #caculate the distance
      (display_message, "@a"),
      (assign, ":show_or_not", 1),
   (try_end),

   (neq, ":show_or_not", 0),
],
  [
   (start_presentation, "prsnt_boss_lifebar"),
])
这个代码的作用时当玩家第一次进入boss周围（距离接下来会设定）时，开始血条的presentation。
这个common也要和其他common_battle一样，加在需要用到它的mt下面。

然后是pesentation，代码如下：
  ("boss_lifebar", prsntf_read_only,0,[
   (ti_on_presentation_load,
   [(set_fixed_point_multiplier, 1000),

      (call_script, "script_get_boss"),
      (assign, ":cur_boss_1", reg1),

      (assign, "$boss_1_display", 0),

      (try_begin),
         (gt, ":cur_boss_1", 0),
         (assign, ":boss_hp", 0),
         (try_for_agents, ":agent_no"),
            (agent_get_troop_id, ":troop_no", ":agent_no"),
            (eq, ":troop_no", ":cur_boss_1"),
            (store_agent_hit_points, ":boss_hp", ":agent_no"),
         (try_end),
         (neq, ":boss_hp", 0),

         (create_mesh_overlay, "$g_presentation_obj_1", "mesh_progressbar_handle"),
         (position_set_x, pos1, 180),
         (position_set_y, pos1, 700),
         (overlay_set_position, "$g_presentation_obj_1", pos1),

         (create_mesh_overlay, reg1, "mesh_progressbar"),
         (position_set_x, pos1, 180),
         (position_set_y, pos1, 700),
         (overlay_set_position, reg1, pos1),

         (str_store_troop_name, s1, ":cur_boss_1"),
         (create_text_overlay, reg1, s1),
         (position_set_x, pos1, 180),
         (position_set_y, pos1, 710),
         (overlay_set_position, reg1, pos1),
         (position_set_x, pos1, 800),
         (position_set_y, pos1, 800),
         (overlay_set_size, reg1, pos1),
         (overlay_set_color, reg1, 0xffffff),

         (assign, "$boss_1_display", 1),
      (try_end),

      (presentation_set_duration, 999999),
      ]),

   (ti_on_presentation_run,
   [
      (call_script, "script_get_boss"),
      (assign, ":cur_boss_1", reg1),

      (try_begin),
         (gt, ":cur_boss_1", 0),
         (try_for_agents, ":agent_no"),
            (agent_get_troop_id, ":troop_no", ":agent_no"),
            (eq, ":troop_no",":cur_boss_1"),
            (try_begin),
               (agent_is_alive, ":agent_no"),
               (store_agent_hit_points, ":boss_hp", ":agent_no"),
               (val_mul, ":boss_hp", 10),
               (position_set_x, pos1, ":boss_hp"),
               (position_set_y, pos1, 1000),
               (overlay_set_size, "$g_presentation_obj_1", pos1),
            (else_try),
               (neg|agent_is_alive, ":agent_no"),
               (eq, "$boss_1_display", 1),
               (overlay_set_display, "$g_presentation_obj_1", 0),
            (try_end),
         (try_end),
      (try_end),

      (try_begin),
      (is_presentation_active, "prsnt_boss_lifebar"),
      (game_key_clicked, gk_view_orders),
      (presentation_set_duration, 0),
      (start_presentation, "prsnt_battle"),
      (try_end),
   ]),
   ]),
加在最后一个]之前就行。这是一个只读格式的prsnt，因此不会影响正常攻击等的操作。

用来定义boss的script，代码如下：
  ("get_boss", [    #use for get boss id
      (assign, ":boss_1", 0),
      (assign, ":distance", 0), #to caculate in how far will the lifebar display, in the other hand can decide if the lifebar should display

      (store_current_scene, ":cur_scene"),
      (try_begin),
         (check_quest_active, "qst_save_town_from_bandits"),
         (party_get_slot, ":town_scene", "$g_starting_town", slot_town_center), #trp_devilman_berserker_mission
         (eq, ":cur_scene", ":town_scene"),
         (assign, ":boss_1", "trp_devilman_berserker_mission"),
         (assign, ":distance", 20),#20 meter
      (try_end),

      (assign, reg1, ":boss_1"),
      (assign, reg4, ":distance"),
]),
只要在中间那个try里面设定好boss是哪个兵种就行了，这个兵种出现、满足条件时血条就会显示。“：distance”便是之前说的距离，一样是在这里设置。

最后还有一个小尾巴，在presentation里，“battle”这个prsnt里，最后一个(try_end),前加上 (start_presentation, "prsnt_boss_lifebar"),作用是关闭战场面板时同时打开血条，战场面板和血条不能兼容，但这样至少能无缝切换。这部分来自Rubik前辈的兵种对比条，特此感谢。
以上便是boss血条的代码，像这样只能允许单boss，但是简单加工（ctrlc、v）之后就能允许多boss，就像附图中那个双人组一样。我自己用的是最高容纳三人的（腐败结晶人并感）
