--Parent is Model
script.Parent.ClickDetector.MouseClick:connect(function() script.Parent.Velocity = Vector3.new(8,0,0) end)
Hello,
Velocity will not work for models, because it does not have the velocity property. To fix this, try using a part as the parent instead.
As for the velocity, try this...
script.Parent.ClickDetector.MouseClick:Connect(function() script.Parent.Velocity = script.Parent.Velocity + Vector3.new(8,0,0) end)
To make the velocity more powerful, you can try multiplying the incremental vector values.
Vector3.new(8,0,0) * 10
