Unity一次性分配大内存后将永远无法GC
Unity版本:2020.2.6f1
平台: win10
打包Exe后出现,编辑器内正常
using System;
using UnityEngine;
public class GCTest : MonoBehaviour
{
const int DefaultSize = 300;
int MemorySize = DefaultSize;
// Start is called before the first frame update
void Start()
{
var strs = Environment.GetCommandLineArgs();
if (strs.Length == 2)
{
if (!int.TryParse(strs[1], out MemorySize))
MemorySize = DefaultSize;
}
}
// Update is called once per frame
void Update()
{
if (Input.GetKeyDown(KeyCode.Space))
{
var bytes = new byte[1024 * 1024 * MemorySize];
}
if (Input.GetKeyDown(KeyCode.KeypadEnter))
{
Debug.LogError("Gc");
GC.Collect();
}
}
}
bytes根本没有被引用,但是Gc是无法回收它的,并且每按下一次空格,就会产生内存增长。
