Last time I tried to do something similar, it didn’t work well, no… I don’t remember the reason, but it didn’t work with me, I’ll try it out again.
Remember to only compare the normal’s Y value. If it’s above 0, not equal or less than, then it’s a floor.

so it would be this?
if upVectorY >= 0 then
-- logic
end
if upVectorY > 0 then
-- logic
end
If the normal’s Y value is 0 or less, the raycast hit a wall or ceiling.

Got ya! let me try this out… It seems so simple, last time I did it with normals, I was doing bunch of crap

Now I remember why this method didn’t work… what happens if you’re on top of a hill? the Y axis would be higher right?
Edit: Imagine a part → The top would be a floor, the sides would be considered walls.
Last time I used normals to detect if they were walls, they gave me this:
a 1 would be equal to a wall… the Y would be equal a decimal if a ramp, and a 0 would be a floor… but it was tough for me to do the logic after that.
When the Y value is 1, it’s a flat floor. Anything above 0 and not equal to 1 is some sort of slope.

Ohhhhh, now I see where you’re going with this…
Should the ray’s origin still be the camera? cause due to the weird inverse ray it’s ruining the script.
Using the camera as a raycasting origin for something like this is a bit weird.

True indeed… but where else should it be? the character’s Y pos? If I do that, the projectiles won’t be able to place down surfaces underneath or above the character, will it?
Technically I’m using the mouse- but yeah it’s also the camera 
Well I would raycast from the projectile’s position to the point of collision

What do I mean by that? this:
Mmm… ok ok, so- how do I direct the ray to the point of collision? with direction I assume?
Use the projectile’s LookVector to detect collision.
I use projectile as a placeholder variable here, I don’t know how you reference it in your script
local origin = projectile.Position;
local direction = projectile.CFrame.LookVector * 5;
Also you can change 5 to however many studs you want to raycast forward.

You made my life so much easier I wanna cry… You don’t know how many different methods I’ve tried… and the most simplest and logical one made by you worked 
This is my 5th day scripting, so yeah I’m not that experienced, thank you so much though!!! I owe you everything. Thank you so much for your time, dedication, and patience
