I have tried to do the following:
tree = script.Parent script.Parent.ClickDetector.MouseClick:Connect(function() tree.Size = Vector3.new(1,2,1) end)
That would work, if I repeated it like 2000 times which I don't plan on doing, so could anyone tell me how I would do this?
EDIT:
I managed to figure it out myself by doing:
function grow() script.Parent.Size = script.Parent.Size + Vector3.new(0.1,0.1,0.1) end script.Parent.ClickDetector.MouseClick:connect(grow)
