性能的测试（关于子弹技能）

聚集在一起时测试 统一debug x64位程序测试：

>>>xxx = []



>>>def create():
   for i in range(100):
      xxx.append(KBEngine.createEntity("NPC",1, (0.0,0.0,0.0), (0.0,0.0,0.0), {}))



>>>create()



>>>create()



>>>create()



>>>create()



>>>create()



>>>create()



>>>create()



>>>create()



>>>create()



>>>create()



>>>len(xxx)
1000

>>>xxx[0]
NPC object at 0x000001F7E25A45A0.

>>>xxx[0].position
Vector3(0.000000, 0.000000, 0.000000), ref=true

>>>for j in range(10000):
   xxx[0].position = (50000, 0, 50000)
   xxx[0].position = (0, 0, 0)

coordinateSystemUpdates消耗为ncall600次， totaltime8.479

分散开测试：

>>>xxx = []



>>>iii = 0



>>>def create():
   global iii
   for i in range(100):
      xxx.append(KBEngine.createEntity("NPC",1, (iii * 500,0.0,0.0), (0.0,0.0,0.0), {}))
      iii += 1




>>>create()



>>>create()



>>>create()



>>>create()



>>>create()



>>>create()



>>>create()



>>>create()



>>>create()



>>>create()



>>>xxx[0].position
Vector3(0.000000, 0.000000, 0.000000), ref=true

>>>for j in range(100):
   xxx[0].position = (50000, 0, 50000)


   xxx[0].position = (0,  0, 0)



>>>for j in range(100):
   xxx[0].position = (50000, 0, 50000)


   xxx[0].position = (0,  0, 0)



>>>len(xxx)
1000

>>>xxx[-1].position
Vector3(499500.000000, 0.000000, 0.000000), ref=true

>>>for j in range(100):
   xxx[-1].position = (50000, 0, 50000)


   xxx[-1].position = (499500,  0, 0)



>>>for j in range(100):
   xxx[-1].position = (50000, 0, 50000)


   xxx[-1].position = (499500,  0, 0)

使用xxx[0]来移动测试 coordinateSystemUpdates消耗为ncall600次， totaltime0.415

使用xxx[-1]来移动测试 coordinateSystemUpdates消耗为ncall600次， totaltime0.8

你可以试试demo。
