#2 将pos旋转至与场景地表垂直的代码。

ms没有自带这个功能。scene_prop刷出来是水平的，如果悬空了很难看。用这个代码就可以把物品的pos旋转到和地面垂直的法线方向。

.....使用实例：
(prop_instance_get_position, pos10, ":prop"),
(call_script,"script_bf_rotate_pos_to_terrain_normal_direction_pos1",pos10,0,0),
(copy_position,pos10,pos1),
(prop_instance_animate_to_position, ":prop", pos10, 移动时间),
(prop_instance_rotate_to_position, ":prop", pos10, 旋转时间),
当然，也可以先旋转再刷物品，就不需要最后两步了。

.....核心代码就是这个bf_rotate_pos_to_terrain_normal_direction_pos1，
第一参量是pos的编号（要旋转的pos，旋转过的返回到pos1里，不覆盖原pos）
第二参量是x轴反转
第三参量是y轴反转
xy反转可设为0（不反转）或者1（反转）。原因是有些模型的方向和pos的xy指向是反的，这样可以增加自由度。
这个script会覆盖掉pos1和pos2的内容。

#1 在场景里刷无马骑兵的代码。

原理很简单，就是在module_troop.py定义一个备份物品栏用的新的兵种，trp_bf_temp，然把要刷的兵种的物品栏存入这个备用的trp_bf_temp，再清除的刷出兵种的马匹，刷兵，最后还原物品栏。这个代码每次刷兵到要执行一次。当然各位也可以修改下变成一个script。
