I was wondering what the best way to animate something in real time would be? For instance if I had a few frames like this:

0

 0

  0

And let's say I had other stuff on the screen that I did not want to re-write again. But I do not want to have a rendering engine to actually move the "0" from one spot to another. So what would the best way to do that be?

You could just clear that line with term.clearLine()

You could code a keyframe system, by moving a line from one "0" to the next one, but it probably wouldn't be that easy.

store everything you want permanent in a table and then for a new frame just clear the screen and print this out and then the actual frame. ofcourse if your permanent stuff is a few lines alone then you cna just clearLine() the other lines

The point of this is to NOT clear the whole screen. The reason is because if you have a game running at 20 FPS(Max tick rate in minecraft) and you redraw the screen every tick there is flickering. The flickering happens in both SMP and SSP.

Clearing single chars by printing " " might work.

Leo Verto: Yeah thats a really good idea

And Human: I have not been experiencing this with my little game which redrew the screen 40 times a second

It always depends on your hardware, but keeping the lag to a minimum is just profit for all users.
