I had to diagnose that engine mouse values - like mouse_force and mickey (here its more noticeable) - are (/have) different (values) on every system (controlled by the mouse driver!?)! That means if you want to integrate it as a game skill you will fail, like I do...
Is there a solution for that?

but at least the mouse moves on every system, doesn't it? so it's up to the user how fast it actually moves.

That's the point: If I move the mouse on system A with the same speed like on system B I get different results!

Are you using time_step to compensate the diffrent frame rates on yor machines?

cheers

Yes.

uesing fps_max,time_step ? how do you use them?

I multiplicate every calculation with time_step.

I don't use fps_max but my timer with while (active) { Timer += time_step; wait(1); } works well.

maby you could use somthing white mouse_sync = on; and
mouse_cursor

srry edit

Interesting hint but goes in the wrong direction because I need a var which is only dependent on the user's way he moves his mouse. mouse_sync makes it even more hardware/system addicted.
