I have the same movement problem in 3 situations:

1-When I rotate my spaceship, the movement is not smooth.


How can I put more fluidity in my movements (acceleration)?

2-I also have the same problem when the spaceship gain or loose speed



3-I use "t" to take off and "l" to land. How can I add a acceleration effect?



Thanks

The key to smooth movement is not to move a fixed amount per loop or key press but to move at a fixed rate per loop. Since each loop can vary in length, you the timer functions to determine the elapsed time per loop and multiply that by your turning rate, etc.

Zircher more or less explained how to get truely fluid movement using the timer()... However, that requires more complex code. I think this will give you the effect you want...



You can apply the same technique to your acceleration/deacceleration and I think your takeoff/landing code also...Well... I hope I helped

Thanks,
It`s perfect! Now my spaceship movements are fluid like I wanted.

But I found an other problem...
It`s the roll effect. I use this code to make the spaceship roll:


When the spaceship is in line with the z axe (o degre on the y axe) everything is ok, but if I turn the ship (ex: 90 degre on the y axe) the roll don`t really work and when it`s facing the opposite direction (180 degree y axe) the roll is reverse.
How can I fix this?
