I’m looking to create lightsaber “streaks” when hitting objects. Such as the ones in fallen order or just commonly seen in the movies and games.
My problem is that I don’t even believe it’s possible in roblox without using parts. (It will most likely lag if I spawn a bunch of neon spheres in a streak line where the saber hits.).
I’ve tried messing with beams and trails but I just can seem to find a good way to do it, these trails also have to go onto the player.
In general experience, I think using a scorch mark on a transparent decal (or surface gui) would be a little better for this, and you could clean this up by adding it to debris…
The good thing about lightsabers is that they’ll always point in a particular direction, and end at a particular point. Thus, for the actual detection of where you should place a lightsaber “streak”, you can use raycasting and Workspace:FindPartOnRay, and it should give you exactly what you need to get the placement and rotation of the decal right.
