Suppose I have 2 bricks, Brick A and Brick B, I want Brick A to shoot at Brick B (I know how to do this), but then I want Brick B to be knocked back as it gets shot, how would I do this, lookvector?

Have you tried unanchoring brick B so then when it is hit it will get knocked over?

You can apply same velocity, that bullet is traveling in, to the block it hits. Make sure to check if brick is unanchored, or the block will get slippery, like conveyer.

By brick I mean player, I have a gun and I`m using a raycast, I want the ray to push the player back a bit on impact.

Then decide how much velocity to apply to the player's torso. Just experiment how much. Here is how I'd try to do it:


multiplier = 10
torso.Velocity = (gun.Handle-rayHitPosition).unit*multiplier

Try increasing multiplier, by few hundreds?

Oh, I hope you spotted my mistake:



torso.Velocity = (gun.Handle.Position-rayHitPosition).unit*multiplier

Well the ray position will be nil, if it won't hit part.

I already have that checked, then I fixed it so that Hit is actually making sense, still no go:

hit.Parent.Torso.Velocity = Vector3.new(script.Parent.Handle.Position-hit.Position)

Be aware that in your RayCasting you also need to cover the fact that you don't hit anything at all.

If that happens that code is useless.

You can better get the Position of the Player torso's and then Knock them back by using that Position. (I would personally use CFraming for this)

hit.Parent.Torso.Velocity = (script.Parent.Handle.Position-hit.Position).unit


You need to use unit, because that's direction and that's how velocity works. Also when you are using unit, remember to multiply it, because it will have small number.

Hmm well by how much did you multiply? Humanoids usually doesn't like to get pushed around.

for i,v in pairs(hit.Parent:GetChildren()) do
if v.className == "Part" then
v.Position = v.Position+(hit.Position-script.Parent.Handle.Position).unit*2
end
end


I tried just moving his Torso too, and if I use MoveTo() the person can be pushed against a wall then end up being teleported over it.
