Mouselook steering has been added in v5.

When mouselook is activated: Left mouse button is for acceleration and left/right arrow keys shift gears.

You can customize the settings for mouselook at the top of the Engine script.

Mouselook has its own value for steering that is unaffected by the normal steering power adjusted in > Controls.

integer         MBnk =              TRUE; //  TRUE or FALSE. Turn on banking mode for mouselook
integer         Auto_Mouselook =    FALSE; // TRUE or FALSE. Turn on mouselook automatically when seating.
integer         Mo_Turn_Power =     500; //75// Mouselook Turning Power;

If you merely want the effect of a mouselook camera while driving with the normal controls, select the SportCam option from the > Camera menu.
