Thanks alot both of you!

And I managed to learn about 2 engine variables I had never used before (until now I only used time_step for these type of things).

How total_ticks keeps up though puzzles me. Since it counts all ticks, how does it manage to not grow too large to fit in whatever variable it is stored? (In the manuall it dosn't detail about that wierd behaviour and how it does it).
