Tire tracks on snow (white sand material)

Help and Feedback Scripting Support
#1

Hey there!

I’m the Chief Executive Officer @ Go-Karting Xtreme, and we launched a snow update. (Basically instead a black concrete material we made it white sand, and used a particle emitter for snow.) Although, some players suggested to make tire tracks.

I do know how to script, but I honestly have no idea how I’d start there. Don’t get me wrong, I’m not asking for a script, but a way of thinking. :slight_smile: How would I accomplish that?

Thanks in advance!

Kind regards,
Jonas

Periodically raycast to find the ground beneath a tire and use Beams.

You can find the position of the tires and clone textures every second or so

Thanks! I’ll try to find out what raycasting is. :slight_smile:

Ray-casting essentially creating a ray that will allow you to determine intersections. Basically, you create a ‘laser’ and with this ‘laser’ you can tell when something blocks the laser. In your case, you can ray cast to determine the position and normal of the ground beneath a tire. You can then incorporate this data with a Beam instance to create the actual tire track textures.

Ah, thank you very much for your time and explanation! I’m not sure if I’ll be able to do that math, but I’m gonna give it a try. :slight_smile:
