python编写unity3D性能测试脚本

要编写Unity3D的性能测试脚本，您需要使用Unity Editor自带的Profiler工具。下面是一个简单的Python脚本示例，它将自动启动Unity Editor，加载一个场景，运行一些测试，并将结果保存到CSV文件中。

import os
import subprocess

# Path to the Unity Editor executable
UNITY_EDITOR_PATH = "/Applications/Unity/Unity.app/Contents/MacOS/Unity"

# Path to the Unity project containing the test scene
UNITY_PROJECT_PATH = "/path/to/unity/project"

# Name of the test scene to load
TEST_SCENE_NAME = "TestScene"

# Number of frames to run the test for
NUM_FRAMES = 1000

# Start the Unity Editor in batch mode and run the tests
def run_tests():
    cmd = [
        UNITY_EDITOR_PATH,
        "-batchmode",
        "-projectPath", UNITY_PROJECT_PATH,
        "-executeMethod", "TestRunner.RunTests",
        "-quit"
    ]
    subprocess.call(cmd)

# Class to run the tests and save the results
class TestRunner:

    # Run the tests and save the results to a CSV file
    @staticmethod
    def RunTests():
        # Load the test scene
        UnityEditor.SceneManagement.EditorSceneManager.OpenScene(TEST_SCENE_NAME)

        # Start the profiler
        UnityEditor.Profiling.Profiler.enabled = True
        UnityEditor.Profiling.Profiler.ClearAllFrames()

        # Run the test for the specified number of frames
        for i in range(NUM_FRAMES):
            UnityEditor.EditorApplication.Step()

        # Stop the profiler and save the results to a CSV file
        UnityEditor.Profiling.Profiler.enabled = False
        results = UnityEditor.Profiling.Profiler.GetRawGpuStatistics()
        with open("test_results.csv", "w") as f:
            f.write("Frame,Time,GPU Time\n")
            for i, result in enumerate(results):
                f.write("{},{},{}\n".format(i, result.frameTime, result.gpuTime))
        UnityEditor.EditorApplication.Exit(0)

# Start the Unity Editor and run the tests
os.chdir(UNITY_PROJECT_PATH)
run_tests()

要使用此脚本，请将其保存为.py文件，然后在终端中运行`python script.py`。请注意，您需要将`UNITY_EDITOR_PATH`，`UNITY_PROJECT_PATH`和`TEST_SCENE_NAME`变量设置为适当的值，以便它们指向正确的Unity Editor可执行文件，Unity项目路径和测试场景名称。
