Ship tuning

[Yodeebe]

Greetings!
I'd like to be able to adjust the rates of roll, yaw, acceleration & stuff for my prototype boa, to make it more fitting of a 125 tonne ship, instead of like a hot hatch on steroids!
I've done it before, in an older game, but it all seems to have changed recently, what with 181, oxz's & stuff, & I can't find the parameters.
Thanks.

That would be the Griff Prototype Boa, I take it?

(ignore this bit.. scroll down to 'EDIT')

None of the recent changes to Oolite should have affected the parameters you mention..

Open the file griff_boa_prototype_normalmapped.oxp/Config/shipdata.plist in a good text editor and scroll down to lines 24-35, where you'll see:

Code: Select all

	max_cargo = 125;
	max_energy = 450; 
	max_flight_pitch = 0.6; 
	max_flight_roll = 0.8; 
	max_flight_speed = 240; 
	max_missiles = 8; 
	missile_launch_position = "0.0 -26.8 73.26";
	model = "griff_prototype_boa_normal_mainhull.dat"; 
	name = "Griff Prototype Boa"; 
	roles = "player";
	scoop_position = "0.2912 -18.2102 59.6099";
	thrust = 36;

No setting is specified for yaw, but you can easily add it if you wish:
max_flight_yaw = 2.2 (or whatever value you prefer)


EDIT:

My bad.. I hadn't realised that Griff had updated the Prototype Boa for 1.80, so it's now like_ship'ed to the oolite_template_boa, and the settings for pitch, roll, etc are no longer included in the shipdata.plist.

You'll need to add the settings you wish to edit to the shipdata.plist yourself.

For the NPC Boa, scroll down to line 45 and paste in the following extra lines:

Code: Select all

	max_flight_pitch = 0.6; 
	max_flight_roll = 0.8; 
	max_flight_speed = 240;
	max_flight_yaw = 2.2;
	thrust = 36; 

Repeat at line 235 for the Player ship.

With the exception of the yaw setting (which I borrowed straight from the wiki page for shipdata.plist), the above values are taken from the original Prototype Boa, so you will probably find they'll tone down the manoeuvrability considerably.. since the oolite_template_boa settings are rather higher than Griff's original version.

oolite_template_boa settings:

Code: Select all

		max_flight_pitch = 1;
		max_flight_roll = 2.8;
		max_flight_speed = 240;
		thrust = 36;

Ooooh, nice, thankyou.

So there was something 'wrong' with it then. I thought it was just me.
I'll probably try & get it how I had it before, which is
accelleration - much slower
top speed - higher
Roll & climb - slower
Yaw - dead slow, more for fine aiming really, and slight landing corrections.

This all adds to the weight & feel imo. plus I'm in vintage 'keyboard only' mode still, so it's quite hard to aim well.

Thanks very much, I'll try those things in the link.

Would you mind copy & pasting the last bit before the insert, and the 1st thing after the insert of each one, so I can make sure it's in the right place please?
Thanks.

[Diziet Sma]

Sure thing..

The code is the same in both places.

Code: Select all

				specular_color = ( 0.2, 0.2, 0.2 );  // Applies when specular map is not used (no shaders) 
				shininess = 15; 
			}; 			
		};
<<- insert new code here ->>
	missile_launch_position = "0.0 -26.8 73.26";

Yaw - dead slow, more for fine aiming really, and slight landing corrections.

This all adds to the weight & feel imo. plus I'm in vintage 'keyboard only' mode still, so it's quite hard to aim well.

Have you tried using the new 'keyboard precision mode' toggle? (just hold down Ctrl whilst applying pitch, roll or yaw)

[Yodeebe]

Oh?
No I hadn't actually.
Nice thanks.
I'll give it a try.

[Yodeebe]

Perfect, thankyou.
I can't notice any difference with the ctrl fine tune button. Does it set to a specific value, or a percentage of the normal value?
Maybe it's just that my chosen values are similar to the fine tune value.
Either way, doesn't matter. my big, heavy, but fast-in-a-straight-line ship is back to normal.
Cheers.

[Diziet Sma]

Good to hear things are back to normal..

Does it set to a specific value, or a percentage of the normal value?
Maybe it's just that my chosen values are similar to the fine tune value.

r5019: Experimental keyboard precision mode. Activated with holding down Ctrl while any of the flight arrow control keys, including yaw, is down. User adjustable by means of the .GNUstepDefaults key "flight-arrow-key-precision-factor". Precision factor default is 0.75 0.5 and the less it is, the higher the effect.
