Hey,
I want to implement a quick motion effect. I can do this with a variable for the speed factor.
E.g.:
Code:
[...]
int speed_factor = 1;
me.x += 5* time_step * speed_factor;   // normal
speed_factor += 0.5;
me.x += 5* time_step * speed_factor;   // faster
[...]


But I thought that there was a function how to do it esier.

Thanks.
