__NOTOC__

This function allows you to create a cinematic-camera-flight, which moves from a specific position to a specific position.

==Syntax==
<syntaxhighlight lang="lua">bool smoothMoveCamera ( float x1, float y1, float z1, float x1t, float y1t, float z1t, float x2, float y2, float z2, float x2t, float y2t, float z2t, int time )</syntaxhighlight>

* '''x1, y1, z1''': The camera's start position.
* '''x1t, y1t, z1t''': The camera's start look at.
* '''x2, y2, z2''': The camera's end position.
* '''x2t, y2t, z2t''': The camera's end look at.
* '''time''': The speed of the camera's movement.

==Code==
This version returns false if a smoothMoveCamera is in progress:

This Version allows cancellation of current smoothMoveCamera progress and doing another one.

Below example is the function as previous one except it's using interpolateBetween function. Also this version may fix little periodic flickering which happen in previous examples.

local tempPos2 = {{},{}}

local function camRender()
