Random 360° turn on part of the track

[David Leal]

Description

On a certain part of the track, the vehicle does a 360° yaw change without reason.
The code that's causing this seems to be on the yaw movement of the car when using mouselook.

panqkart/mods/lib_mount/init.lua

Lines 364 to 381 in 3faaaa1

 				local yaw = entity.object:get_yaw() 
 				local yaw_delta = entity.driver:get_look_horizontal() - yaw + math.rad(90) 
 				if yaw_delta > math.pi then 
 					yaw_delta = yaw_delta - math.pi *2 
 				elseif yaw_delta < - math.pi then 
 					yaw_delta = yaw_delta + math.pi* 2 
 				end 
 				local yaw_sign = get_sign(yaw_delta) 
 				if yaw_sign == 0 then 
 					yaw_sign = 1 
 				end 
 				yaw_delta = math.abs(yaw_delta) 
 				if yaw_delta > math.pi / 2 then 
 					yaw_delta = math.pi / 2 
 				end 
 				local yaw_speed = yaw_delta * entity.turn_spd 
 				yaw_speed = yaw_speed * dtime 
 				entity.object:set_yaw(yaw + yaw_sign*yaw_speed) 

Any help with this would be greatly appreciated. Thanks. 🙂
