It may be more difficult, but is useful if you've hit the keyframe cap.
Also, in the case of simulating the jump to lightspeed, it is easier as the LUA code allows for the incremental increase of speed that would take too many keyframes in ZE.
It would take a lot of work, but you could also make some very smooth cornering animations, as I plan to do.
The other problem this solves [somewhat] that of 'Animating Vehicles', where people want to have the Script sort of drive a vehicle a player is in or whatever.
Posted below is a recursive[sic?] script that repeatedly moves an object to a new matrix, using CreateMatrix, that is a given distance from the last, until the given number of frames is exceeded (integer variable a). The result is a smooth animation that is physics compatible, so long as the FPS is high enough. The FPS is controlled by a Timer, with a length of 1/60th a second, which restarts itself.
The below code produces a smooth acceleration, done by increasing the translation(movement) value by 1/60th of itself each frame, which means it~doubles in distance every second, resulting in a speed increase.
If wanted, the division variable can be made smaller (faster acceleration, but less smooth)
or the timer value can be made smaller (smoother, faster animation as a whole)
