Unity-OnBeginDrag/OnDrag e.t.c无法正常工作 [英] Unity - OnBeginDrag / OnDrag e.t.c not working

问题描述

尝试使以下代码起作用:

Trying to get the following code to work:

public void OnBeginDrag(PointerEventData eventData)
{
    if (item.ID != -1)
    {
        transform.position = eventData.position;
    }

}

忽略item.ID！= -1，我确定这不是问题所在，因为无论如何，它都不起作用.

Ignore item.ID != -1, I know for sure that's not the issue because it doesn't work no matter what the condition.

我需要知道的是，是否需要启用画布或图像中的某个设置(此脚本附加到面板内的图像上)才能使交互起作用.我本该宣誓要启用鼠标才能在画布上工作.

What I need to know is if there is a setting in the canvas or in the image (this script is attached to an image inside a panel) that needs to be enabled to get interaction to work. I could've sworn there was something that needs to be enabled to get the mouse working with the canvas.

谢谢
