-- OnAddToFlow can be used to set parameters and other processing functions when the Tool is add to a comp

function OnAddToFlow() local grad = Gradient()

if InNewTool:GetSource(0).Value >= 0.5 then

-- There is no default attribute for gradients. It’s always black to white.

-- To have a different gradient for new tools, we’ll set one up here but

-- only once. The "NewTool" flag is cleared immediately afterwards so we

-- don’t overwrite gradients when the comp is reopened at a later time.

grad:AddColor(0.0, Pixel({R = 1.0, G = 0, B = 0, A = 1}))

grad:AddColor(0.5, Pixel({R = 0, G = 1.0, B = 0, A = 1}))

InGradient:SetSource(grad, 0, 0)
