Keyboard steer: [Keyboard - no help / Keyboard - stabilised / Mouse steer]
This is how you select your input method:
- Keyboard - no help directly translates button presses into wheel movement. So long as the button is held down, the wheel will continue turning until it reaches maximum lock. There is an auto return to centre function when no steering keys are pressed. Both rates are configurable. Also, pressing both left and right will hold the wheel in its current position. This steering method is definitely not recommended, since it is impractically difficult to race with.
- Keyboard - stabilised has two main differences to "keyboard - no help". Firstly, it limits the movement of the wheel depending on the amount of grip the tyres have. This limit is also adjustable. Secondly it adds a small amount of automatic counter-steering to help balance the car. While this is a driving aid (and the turn limit can be considered one as well), it is essential for using such a basic input device for a task it obviously would never be used to do in real life. Thankfully the keyboard steering is highly configurable in LFS so you should be able to get it to work to your preference.
- Mouse steer (rather obviously) lets you use the mouse for steering and assign throttle and brake to buttons (be they on your keyboard or your mouse).
Auto gear shift: [Yes / No]
If enabled, the computer will change gear for you (and probably at the wrong time too).
Button control rate:
This is for when you assign a button to an analogue control (e.g. handbrake or clutch) how fast the control moves when the button is pressed. Higher is faster.
Mouse steer only:
Steer centre reduction:
This is a non-linearity slider and is designed to make it easier to control the car buy reducing straight line twitchyness. A setting of 0.0 gives fully linear steering whereas a setting of 1.0 gives fully non-linear steering. A setting of 0.4 to 0.6 is recommended.
Keyboard steer only:
Steer rate:
The speed the wheel turns when you press the left or right steer buttons. Higher values will make the car more responsive but less stable, and vice versa.
Return rate:
The speed the wheel turns when you depress the left or right steer buttons. Higher values will make the car more responsive but less stable, and vice versa. It is usual to use a lower value for the return rate, between 50 to 75% of the steer rate.
Fast steer multiplier:
When holding the "Steer Fast" key, the steer rate will be temporarily increased. This slider controls by what percentage it will be increased. With the default setting of 2.00, the steer rate will be doubled. This fast steering option can be useful when quick corrections are needed, such as when counter-steering. Chances are you're going to crash anyway so this option is of limited helpfulness.
Slow steer multiplier:
When holding the "Steer Slow" key, the steer rate will be temporarily reduced. This slider controls by what percentage it will be reduced. With the default setting of 0.50, the steer rate will be halved. This slow steering option is most useful at higher speeds when finer control over the vehicle is needed. However the keyboard steering is automatically speed sensitive, so there is really no need to ever use this anyway.
Limit multiplier: (Only available with 'Keyboard - stabilised')
A setting of 1.0 limits the wheel turn to that of the available grip of the tyres. Settings higher than this allow you to turn further, to induce understeer. Settings lower than 1.0 means you won't get so close to the limits of the car, so control is retained. The further you reduce this setting, the easier the car will be to drive, at the sacrifice of cornering speed.
In the Buttons 1 subsection you select which button to assign to the function labelled to the right of the button. To choose and lock in your selection, simply click on the button to highlight it, a text message with instructions will appear at bottom of screen, Click desired button or key you wish to associate with this button etc. Do this for all Button 1 selections, then move on to Button 2 section using the same method to select and assign your desired keys or buttons to control the views etc.
When you have completed this, mouse users and keyboard users are finished, and may want to skip the section on wheels and joysticks. And go directly to the far right of this screen and look closely at the various key sequences and what they do. i.e. (Reserved keys) and Shift + combinations.
