hmm I used the code as it is and tried a couple of other things but every time I try the plane just seems to go really far and even when I reduced the numbers it didnt go slower.. Kinda problematic, anybody else?

action plane()
{
VECTOR force;
VECTOR dist;
while(1)
{
force.x = 10 * key_force.x * time_step; // play with 10
accelerate(dist.x,force.x,0.5); // play with 0.5 (lower it)
if (key_cuu) c_move(my,dist,nullvector,IGNORE_PASSABLE|GLIDE);
wait(1);
}
}
