I have a linear velocity constraint on the server moving the character in the wrong direction. It only happens after I use a dash move. In the video, I’ve already used the dash, the next time I activate the constraint it uses the wrong direction- except printing the properties shows its close to the right direction? The first time I punch moves in the wrong direction, the second time it move in the correct direction.
The strange thing is- the properties show that the properties at the time of the incorrect direction are similar to that of the correct direction? The incorrect direction seems to be locked to an axis.
Dash Properties (Happens before the error):
Error Properties (This moves in the incorrect direction?):
Second-Attempt Properties (This is the second punch that shows correct direction):

Drag Function (Calls Constraint Function):
function Mechanics.Drag(Attacker: Model, Victims: {Model}, Distance: number)
local averagePosition = Vector3.zero
local roots = {Attacker.PrimaryPart}
for i,Victim in Victims do
averagePosition = averagePosition + Victim.PrimaryPart.Position
table.insert(roots, Victim.PrimaryPart)
end
averagePosition = averagePosition / #Victims
local dragTime, dragRatio = .2, 1--4/5
local damagePosition = Attacker.PrimaryPart.Position
local direction = (averagePosition - Attacker.PrimaryPart.Position).Unit
direction = Vector3.new(direction.X, 0, direction.Z) * Distance
if true and (averagePosition - damagePosition).Magnitude > (Attacker.PrimaryPart.Size.Z * 4)
or true -- always
then
task.spawn(function()
Constraints.LinearVelocity:Start(Attacker.PrimaryPart, dragTime, direction, Distance, nil, Enum.VelocityConstraintMode.Line)
end)
end
for i,victim in pairs(Victims) do
task.spawn(function()
Constraints.LinearVelocity:Start(victim.PrimaryPart, dragTime, direction, Distance * dragRatio, nil, Enum.VelocityConstraintMode.Line)
