Detailed Description

You can use ExecuteLuaAction to run a Lua script that implements application logic.

ExecuteLuaAction initializes Lua if it is not initialized to guarantee that the Lua script runs when the Action invokes.

To use the ExecuteLuaAction:

Create a BinaryResource that contains the Lua script that you want to run.
Register the binary resource to the resource manager.
Set the ScriptUrlProperty to the url of the binary resource.
Add the action to a trigger and the trigger to a node.

See also: Trigger, BinaryResource

Since: Kanzi 3.9.9
