long Unity 分配的内存量。如果性能分析器不可用,则返回 0。
The total memory allocated by the internal allocators in Unity. Unity reserves large pools of memory from the system; this includes double the required memory for textures becuase Unity keeps a copy of each texture on both the CPU and GPU. This function returns the amount of used memory in those pools.

public class Example : MonoBehaviour { void Update() { Debug.Log("Total Reserved memory by Unity: " + Profiler.GetTotalReservedMemoryLong() + "Bytes"); Debug.Log("- Allocated memory by Unity: " + Profiler.GetTotalAllocatedMemoryLong() + "Bytes"); Debug.Log("- Reserved but not allocated: " + Profiler.GetTotalUnusedReservedMemoryLong() + "Bytes"); } }
