This first set of functions is taking longer than I had planned, but I am still making progress. :)
Here is where I have landed with the "Move Camera Over Time" function. There will be a similar one for "Move Camera At Speed" to move it at a fixed speed (in voxels/sec) as opposed to a duration of time. There is an optional "Look At" parameter to have the camera rotate towards a particular entity or coordinate as it moves to the new location.
Besides cleaning up and tweaking some things, I need to make a modification to the way scripts are executed in-game to account for these types of actions. For example, right now if you triggered a camera move from a script followed by a second camera move, the game would not wait for the first camera move to complete before starting the second, so I need to add in some timing to hold the script from continuing until certain functions like these have finished executing.
