On the json side
Code: Select all
"action":{"type":"call","id":"$targetscriptdraftid","code":"functionName","frame":42}
Code: Select all
function script:functionName(x, y, lvl, frame)
-- Do some stuff
end
Remarks:
-The "frame" parameter is there to pass custom information (an integer) to the function; you don't have to use it.
-If you don't provide a target script via the "id" tag all scripts that contain a function as specified by "code" will be called.
-In case there are mutliple scripts attached to the object identified by "id" all of their script:functionName functions will be called
-The target function has to be attached to a script as shown in the definition above (script:functionName)
-Return values of the function will be ignored by fun
For technical reasons you cannot access Lua from fun conditions. That is because fun conditions are optimized to be evaluated concurrently which is not supported by Lua.
