How does it shorten ,to no was error?

wheel[0].create(car,Matrix().setPos(Vec( 1,-0.5, 1.5)),susp,r,susp_damping,susp_spring);

please check the tutorial

I did yes,but changes do not see.

Quote:Wheel::Param wp,susp,susp_damping,susp_spring,r;
wp.r=0,
wp.susp=0,
wp.susp_damping=0,
wp.susp_spring=100;
wheel[0].create(car,Matrix().setPos(Vec( 1,-0.5, 1.5)),(susp,susp_damping,susp_spring,r));

Wheel::Param wp; // wheel parameters
wheel[0].create(car,Matrix().setPos(Vec( 1,-0.5, 1.5)),wp);
