Scripting Node API functions ​

Scripting Node is a special node that can be modified using Lua scripts. You can specify node properties by creating a new Operation and attaching it to the node. The API provides a set of functions - on_init and on_update_values - that can be used in the script to interact with the node, you can also access the node's properties by using the self.node object. To save custom properties, you can use the self table, for example self.my_property = 1.

Example of a simple script:

lua
self.operation = Operation.new(
	{ x = ValueType.Float, y = ValueType.Float },
	{ result = ValueType.Vec3 }
)
self.on_init = function() print("Node initialized!") end
self.on_update_values = function()
	local operator = self.node:as_operator()
	if (operator:is_input_plugged(1) and operator:is_input_plugged(2)) then
		local x = operator:get_input_float(1)
		local y = operator:get_input_float(2)
		operator:set_value(Vec3.new(x, y, x + y))
	end
end

attribute self.operation: Operation ​

The operation which is used to create the node.

attribute self.node: Operator ​

The node that the script is attached to.

function self.on_init() ​

Called when the node is created. Function is protected, errors will be caught and printed to the console.

function self.on_update_values() ​

Called when the node's values are updated. Function is protected, errors will be caught and printed to the console.
