My AI Car Script makes delay. Please help me

Help and Feedback Scripting Support

You can write your topic however you want, but you need to answer these questions:

  1. What do you want to achieve? Keep it simple and clear!

I made script which detect Part(named Goal) and check position difference between part and a front vector of car. Wheels are composed of Hinge Constraints. Calculate the angle and using HingeConstraint.TargetAngle. Car Speeds are controlled by HingeConstraint.AngularVelocity.

  1. What is the issue? Include screenshots / videos if possible!

  2. What solutions have you tried so far? Did you look for solutions on the Developer Hub?

I rewrite other scripts beacause of this problem. I check that there is no laggy when I disable this script. I’m pretty sure this scripts make problem. I clone and spawn 12 Cars on my workspace.

After that, you should include more details if you have any. Try to make your topic as descriptive as possible, so that it’s easier for people to help you!
