血槽计算公式求教

jiushiainilip19

如图 血槽采用四张图片来设定

每一张图片只计算角色25%的血量

这个公式应该怎么去计算呢！

就像一些网络游戏一样   血条有好几层一样

def draw_actor_hp1_bar(actor, x, y,height=60)
 
    bitmap3=Bitmap.new("Graphics/Pictures/xue4")
    w4 = 1.0 * actor.hp / actor.maxhp * height
    src_rect3 = Rect.new(0, 0, 60,w4)
    self.contents.blt(x+300, y, bitmap3, src_rect3)
 
    bitmap2=Bitmap.new("Graphics/Pictures/xue3") # 60  60
    w3 = 1.0 * actor.hp / actor.maxhp * height
    src_rect2 = Rect.new(0, 0, 60,w3)
    self.contents.blt(x+200, y, bitmap2, src_rect2)
 
    bitmap1=Bitmap.new("Graphics/Pictures/xue2")

随手瞎写的

1. def draw_actor_hp1_bar(actor, x, y,height=60)
   
2.     ar = []
   
3.     data = actor.hp
   
4.     names = ["xue4","xue3","xue2","xue1"]
   
5.     n = actor.maxhp / 4
   
6.     4.times do
   
7.       nhp = [[n, data].min, 0].max
   
8.       data -= nhp
   
9.       ar << nhp
   
10.     end
    
11.     for i in 0..3
    
12.       next if i != 3 and ar[i+1] == n
    
13.       bitmap = Bitmap.new("Graphics/Pictures/#{names[i]}")
    
14.       w = 1.0 * ar[i] / n * height
    
15.       src_rect = Rect.new(0, 0, 60, w)
    
16.       self.contents.blt(x, y, bitmap, src_rect)
    
17.     end
    
18.   end
