Lua Scripts Functions

[Yue]

Hi, I have a question about the functions.

 

function Script:UpdatePlayer()


end


function UpdatePlayer()


end

What is the difference between defining this function differently?

[Rick]

function UpdatePlayer()


end

This is a global function and once defined you can call it from any script in your app. The other one's scope is on that entity only. So you'd first need a reference to that entities script (like entity1.script:UpdatePlayer()) to be able to call it. Note that inside UpdatePlayer() you can't use the normal self.entity because inside that script it doesn't know anything about that. So global functions work on global data or data you pass into it from a parameter (in this case you have no parameter).

In that case as step a parameter?
 

function Script:UpdatePlayer( self )
	self.entity:Hide() 
    
end

self.UpdatePlayer( self.entity ) <<< Ok?
 

[Yue]

Ok, solved.
 

self:UpdatePlayer(self.entity)
	
end


function Script:UpdatePlayer(entidad)
	
	entidad:Hide()
	
	System:Print(entidad)
	
end
