提高太多UI图像上的帧速率-Unity UI [英] Improve Frame rate on too many UI Images - Unity UI

问题描述

在我的单个页面中，有很多纹理需要渲染，然后我才刚刚遇到屏幕打开问题，但这可以解决这个建议:

In my single page, there were so many textures those I require to render before I was just facing problem in just screen opening but this I was able to resolve this suggestion:

可用于画布UI对象的OnBecomeVisible

这是我用于此目的的实际代码:

Here is the actual code that I used for this purpose:

public void OnValueChangeRefreshCards (Vector2 valueChange)
{
    elapsedYDist += valueChange.y;

    if (elapsedYDist > 3f) {
        elapsedYDist = 0f;
        for (int i = 0; i < GameConstants.TOTAL_ROSE_COUNT; i++) {
            Card card = roseList [i].GetComponent<Card> ();

            if (RendererExtensions.IsVisibleFrom (card.MyRectTransform, Camera.main))
                card.roseImage.enabled = true;
            else
                card.roseImage.enabled = false;
        }
    }
}

但是现在我开始过多的丢帧率相关问题，因此即使滚动页面也对我来说真的很困难. 请查看随附的视频，以进一步了解我所面临的问题. NameThatRose-低帧速率

But now I started too much framerate lose related issue so even scrolling of page become really difficult for me. Please check the attached video for more clearance about the issue, I was facing. NameThatRose - Low Frame Rate

请给我一些进一步改进的建议.

Please give me some suggestions for next improvements.

编辑:这是我的探查器输出.

推荐答案

您可以尝试一些尝试来找出导致fps低的原因.

You can try few things to find out whats causing the low fps.

1. 使用 profiler 进行深入剖析，以找出哪个UI调用花费更多时间.就像我做的一样这里. 由于Image继承自UIMaskableGraphics，因此它将为列表中的每个图像调用MaskableGraphics.OnEnable()每帧.这会占用一些时间，您可以在此处查看:

1. Use profiler to deep profile to find out which UI call is taking more time. Like what I did here. As Image inherits from UIMaskableGraphics, it calls MaskableGraphics.OnEnable() every frame for every image in your list. This takes up time which you can see here:

1. 我相信您的OnValueChanged方法在每一帧都被调用，这只会使启用/禁用迭代及其处理时间倍增.您可以限制通话时间，例如每秒处理4次.

1. I believe your OnValueChanged method is called every frame this would only multiply the enable/disable iterations and its processing time. You can limit the call by some time, processing 4 times a second for example.

float timeSinceLastUpdate = 0;

void Update()
{
    timeSinceLastUpdate += Time.deltaTime;
}

public void OnValueChangeRefreshCards (Vector2 valueChange)
{
    if(timeSinceLastUpdate < 0.25f)
    {
        return;
    }
    timeSinceLastUpdate = 0;

    // do your stuff here...
}

您需要处理250张以上的图像，每一帧都需要处理，这对于较旧的Android设备而言非常重要，因为MaskableGraphics.OnEnable()调用可能是罪魁祸首.您可以根据需要避免更改状态:

You have 250+ images to process every frame which is a big deal for older Android devices, again as MaskableGraphics.OnEnable() call can be the culprit. You can avoid changing the state if it is required:

if (RendererExtensions.IsVisibleFrom (card.MyRectTransform, Camera.main))
{
    if(!card.roseImage.enalbed)
        card.roseImage.enabled = true;
}
else
{
    if(card.roseImage.enalbed)
        card.roseImage.enabled = false;     
}
