how to chain raycast

[limpid folio]

I want to create like a superpowers datapack and i am making like nature power and I need to make a power that summon vines in the directions that the player is looking but not like the vine block I need like the particles that every few blocks the ray cast would split into random directions but still move in the general direction that the player was looking at

So like a branching thing?
Just make a score that decreases and if it's 0 put it back and choose some random direction with /random where you make a new raycast

Also probably a slowcast would be better

how do I change the direction with /random

[keen yew]

• Summon a Marker
• /execute store result entity <marker> Rot[0] int 1 run random value <min>..<max>
• /execute as <marker> at @s run function <raycast>

wait but I want it to be in the general direction that I fired with like a range of like ~-40..40 ~ and not a set value cuz I dont want it return to the back

and how do I make it faster?

I wouldn't use a marker but instead use recursive functions. The user won't really see the difference between a rotation of 1 deg and a rotation of 2 deg, so you can just hardcode some rotations and select between those to call the same function again
