# How to make wheelcollider not stutter when moving on high speed?

I have a wheelcollider attached on a rigidbody and i move the object using : "transform.position += transform.forward * speed * input.getkey(keycode.uparrow)" And when the speed increasing the wheelcollider start stuttering How to solve it? Do i wrong using the script above? Or something? Can anyone solve it? thanks

• What did you try to solve the issue? What's your frame rate? Against what does it stutter/what's your surface? Are you mixing forces with this transform modification? You might want to add a link to a youtube video or an animated gif to the question to show us what happens. – Vaillancourt Oct 3 at 1:27
• Are you possibly seeing temporal aliasing like happens with video? (The so-called wagon-wheel effect?) – user1118321 Oct 3 at 2:22
• Aa..... I dont really understand what is mixing forces with transform modification sorry for that i still noob to unity anyway thanks for the answers @Alexandre – Sugendout Oct 4 at 1:58
• And thanks for your answer too @user111 – Sugendout Oct 4 at 2:02

wheel collider is for making movements for wehicle and everything that works with wheels. you should use WheelCollider.motorTorqueotherwise you get some physics problems like stuttering as you said.
