Seems like a good idea to me. I have sometimes when I had a very fast ship tinkered with the pitch- and role-rate in its shipdata, simply reducing the values to make it handable more precisely.

Sounds like a good idea indeed. I've often felt that the movement of MSX's Elite was different to Oolite. If you could control/tweak acc/dec rates for all axes you could finetune your movement to your liking. That's what i would like.

I remember playing Elite on the MSX with the kb and joystick, steering went fluidly, i was in sync with my ships location and heading all the time. For a certain turn i knew how long i had to keep the directional button pressed, only slightly correcting now and then. This was most valued during combats ofcourse. With Oolite i seem to never quite get in sync with my ship. It's not because of the keyboard because i'm fine with that, it's the movement speed.

Never mind! There have been older discussions re-animated here before, and...

It lives! :shock:

you know, it would be nice to have rough and fine movement controls. perhaps 'fnct'+(movement key) for large scale rough movement, and the regular keys for fine control movement. =D

Yay, another suggestion I requested made it into the trunk! Gosh, I've been away too long (or, for you readers, perhaps not long enough). :wink:

Yes, it has made it into the trunk, but there is a but!

For the time being this is an experimental addition. Our current Supreme Grand Admiral hasn't yet decided whether it will stay in the trunk for the MNSR*.

If the ability to yaw is left in future versions, it would be nice if yaw could be mapped to a joystick axis, just as one can do so with pitch and roll now. And, of course, the yaw axis should respond to the "precision movement" [joystick] toggle that the other axes respond to.
Sorry to re-animate a zombie thread.
But, I assume this has not been implemented yet?
I have the yaw controls (,< and .> keys) mapped to the yaw axis of my joystick, but they are a bit vicious! I have increased the dead zone on the yaw axis, which has helped a bit, not perfect tho'.
Analogue yaw would be very nice. :)

Wish granted.

The following is the output of 'svn diff' against svn current (rev 1501).

Some notes:
After applying this you'll have to go to the joystick config page and remap thrust, as well as yaw.

I've made the max default yaw half of the max default pitch. IMHO, you should have more pitch command than yaw command. This can be overriding in the ship plists (currently I don't think any ships define a max yaw), or you can choose not to apply that portion of my patch (only 2 lines are different)

I've changed some abs() calls to fabs(). Took me forever to figure out why my joystick wasn't working in yaw; this was it.

If I have the time (I just finished Spring Break here), I want to look into adding Joystick hihat support for views. Mine is mapped as 2 axes (only returns -1, 0, and 1), and currently the game just supports buttons for changing views.

I’d prefer to leave this to someone with a working SDL build, and maybe even a joystick. :-)

Ok, I was reviewing the code a bit more, and while that code works, I'm going to change it just a bit. Basically I copied the method of getting the joystick info from the pitch/roll code, which uses getPitchRollAxis, which returns an NSPoint, which is 2 doubles. I used that, so virtualYaw.y was always 0. I noticed that instead I can use the getAxisState function, which just returns a double. This implementation will be a bit nicer. Expect a new version (hopefully soon).

I cannot check this code myself either, as I do not use joystick, but if I prepare a test build, based on 1.70, maybe someone with a joystick could give it a go? If all is reported good, then we could go on and add it, I guess.
