Unreal Engine NPC Car Tutorial: Speed Control

[@fyrefighter13]

If you're wondering how to get a vehicle to speed up or slow down based on curves and road conditions, implement logic that calculates stopping distance based on current throttle and braking intensity. Find the braking friction, wheel torque, and engine torque values in the UChaosWheeledVehicleComponent, and then calculate how much brake or throttle is needed to get from the current speed to the target speed by the given distance.
It's exponentially more beneficial than setting hard throttle or speed limits, as the speed changes are adaptive to the road conditions.

Thank you so much for updating this speed control tutorial in UE5.1!

[@Extrone]

Thanks for the gear ratio equation, been trying to find it forever.

[@oliverholmberg1462]

Thank you for making a new tutorial on this!!

[@skakun.design]

Thanks for video! How you did the GetPath function? Whithout it my logic doesn't work correct. My car start move forward immediately when i start scene wihout this function ((

[@Seredias.]

@@skakun.design Get Path controls only the Steering. The Throttle Input the Speed.

[@MannDevani]

Thank you, but can you tell me how do i lower speed on turns?

[@Seredias.]

By placing a Blueprint Actor with a Box Collision where the turn is to set the Target Speed on overlap. Very similar to my Path calculation Tutorial: th-cam.com/video/H8b2p7L1j1c/w-d-xo.htmlsi=4dKsRJ_-lPgfyITF

Maybe you know how to make a timer for an AI so that it starts when the race starts and stops when it arrives at the finish line? I would be glad to see your video on solving this issue.

[@Seredias.]

Did you already watched my Race Game Tutorial Series: th-cam.com/play/PLSc29g4OjKUN36Fp7HsNpGV7OFjqmkKbf.html&si=w0n4hMs5SRrM5-Iu

[@Зритель-ш6у]

@@Seredias. Yes. There is no timer for character. You only have it for vehicle.

[@Seredias.]

@@Зритель-ш6у Oh you mean for Human AI. Well its a simple timer so it's not that complicated to adjust.

[@Зритель-ш6у]

@@Seredias. I can't do it myself. I need a position in the race among Human AI. You can make a video tutorial for Human AI.

[@Зритель-ш6у]

@@Seredias. I need a time timer not from my Human, but from Human AI. We also need Human's position in the race among Human AI.

Hii thanks can you make the indicator right and left. The car is about to turn on left so the indicator will flick

[@Seredias.]

This here should give you an Idea of the Concept: th-cam.com/video/wCtxb-yHMPc/w-d-xo.htmlsi=3ktCRzwVGXaCAURD

how did you add the street bridge to unreal project

[@raulguedes7247]

Hey man, this is working great. But i need something extra. Im trying to tell Unreal to stop or increase accelaration when in contact with certain textures. Can you help me?

[@Seredias.]

You could combine it with this System: th-cam.com/video/YKp19_4P2Fk/w-d-xo.htmlsi=ieJXgu3ND5yNS5F4

[@raulguedes7247]

Hey man. Works great. I ll just like to add like a condintion that if a car is cruisin in a certain floor(texture) the throttle shuts. Can you help?

[@shanliumoshi7904]

thanks

[@lo1d]

very good tutorial but how can I make it to stop

[@Seredias.]

By setting the Throttle Input to 0 and the Handbrake Input to true.

[@rifat.ahammed]

Thanks

[@laurentiupolesciuc2817]

Hey bro, could you make a tutorial on how to make something similar to Gran Turismo driving school? Various tasks, awards, gold, silver, bronze, etc. and when the task is completed, open the next task

[@Seredias.]

Technically yes, but there is not much to explain. It basically "Drive to the finish in range of time goal". That would be this one with obstacles: th-cam.com/video/pVlR8B8AM8E/w-d-xo.html&feature=share7
