Roblox Lerp Function
Its likely that you wouldnt use it in update anyway.
Roblox lerp function. This function will trigger the events that have been connected. 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. But if youre specifically looking to lerp the camera you can use the lerp method of the cframe like so. The lerp function will take two vectors and an alpha the last argument a number between 0 and 1 and according to the alpha will create a new vector between the two other positions.
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.
