Particle Collision?

Help and Feedback Scripting Support
#1

Okay, i wanna make particles, and i think of two ways of collisions:

  1. Raycast
    Just raycast from particle vector, to particle velocity vector, if collide we reflect velocity and apply gravity.
  2. Touched
    Uses object/mesh info, and if object touched, we reflect velocity, and add gravity

Which one is better, and why?

#2

A Ray will always be more accurate. Touched events are a bit hit and miss particularly with high velocity objects.
Why?, A Ray will see the intercepting part, whereas the Touched event relies upon far less accurate collisions being detected between parts.

#3

Oh, okay, thanks! Will make it with raycast, maybe some experimental methods

#4

It isn’t possible to raycast from a particle’s position since particles are handled internally by the physics/rendering engine which is written in C++.

#5

im not about roblox built-in particles
