Handling boundary box for camera to prevent movement outside

[hansyulian]

What is your question:

So I would like to make the camera movement smooth in this example of bounding the camera position to the box:

I figured out the problem is because the camera move before i check the validity of the position and thus after i found out that the camera is moving out of the box, i just throw it back inside the box based on the closest point to the box. this causes the jaggy camera movement which is not nice.

i would like to find is there a way for either:

• hook on the camera's new position before it's moved, something like onBeforeCameraPositionChange(before, after)
• smooth out the throw back, preventing the jaggy camera movement?
• any better solution than what i have?
