Anonymous Function inside Anonymous Function

[DarkLink]

I guess this doesnt work on LUA ? Because on my code the part of the removeEventHandler is not working...

I have no errors on the clientscript ..

Code:

  
addEventHandler( "onClientMouseEnter", small,  
    function() 
         
        addEventHandler("onClientRender", getRootElement(), function() textAmmo("7 pistol, 12 shotgun, 24 submachine, 30 assault rifles, 5 rifle")  end) 
         
         
    end, false) 
    addEventHandler("onClientMouseLeave", small,  
    function() 
        removeEventHandler("onClientRender", getRootElement(), function() textAmmo("7 pistol, 12 shotgun, 24 submachine, 30 assault rifles, 5 rifle")  end) 
    end, false) 
  

And I assure you, that small is defined, and textAmmo is fine..

It works to addEventHandler, but removing the event handler is not working...

Would appreciate some help! thanks again!

Aside from this looking horrible, you can't remove a function like that. You are defining a new function and passing it to rEH., even if it's exactly the same.

Assign it to a local variable, then pass that to rEH.

I cant do it..

Do you mean this ?

  
local textAmmoFunction  
  
function textAmmo(text) 
    if(ops and isElement(ops)) then 
                local x,y = guiGetPosition(ops, false) 
                local x1,y1 = guiGetSize (ops, false) 
                dxDrawText ( text, x + 30, y + y1/1.5 ,x + x1, y+y1, tocolor(255,255,255),  
                     1,"default", "left", "top", false, true, true) 
    end 
end 
  
  
addEventHandler( "onClientMouseEnter", small,  
    function() 
        textAmmoFunction = textAmmo("7 pistol, 12 shotgun, 24 submachine, 30 assault rifles, 5 rifle") 
        addEventHandler("onClientRender", getRootElement(), textAmmoFunction) 
         
         
    end, false) 
    addEventHandler("onClientMouseLeave", small,  
    function() 
        removeEventHandler("onClientRender", getRootElement(), textAmmoFunction) 
    end, false)

Nice to see that some people read LUA wikis yet.

Of course!

I always try to find my answer somewhere else, but most of times I need to brother someone here on forum eheh

Heheh, function-as-variable can come as kind of a surprise if you're not used to it - relatively few languages support this kind of thing.

Might actually be my favorite thing about Lua. :3

(Edit: oh, and "horrible" might have been a slight exaggeration. If you indent it sanely, that'll go a long way. )
