Roblox Lerp Function
Its likely that you wouldnt use it in update anyway.
Roblox lerp function. Took me about 3 minutes. Roblox added a cframelerp function recently so i decided to make this. Note that the lerp method short for linear interpolation only applies to cframes so youre going to be modifying the cframe property of the part instead of the position property which is a vector3. So if the alpha is 5 or one half it will create a vector halfway between the two other vectors in this case part and part2.
But if youre specifically looking to lerp the camera you can use the lerp method of the cframe like so.
