[Unity Engine] 關於我在Unity中踩的一些坑 - UI篇

tags: `TODO` `Unity Engine`

Image Not Showing Possible Reasons

The image file may be corrupted
The server hosting the image is unavailable
The image path is incorrect
The image format is not supported

持續更新中…因為坑只會越踩越多

按鈕點下去沒反應…

UI Button不能按可能來自以下這幾個原因
請先利用EventSystem查看點到甚麼物件

Button沒有Raycast Target(預設為Image元件)，或是Raycast Target沒有打勾(為false)
Iteractable們有打勾(為false)
如果Button的Parent Canvas是巢狀的，則該Canvas需要加上GraphicsRaycaster元件

// nested canvas
RectTransform

場景中沒有EventSystem
