Requesting function help.

[patriot]

Hi guys,

I need a clientside function that creates a dxText using parameters, for example:

function dxText(string text, local time)

Parameters:

string text = the text of the dxDrawtext.

local time = the time, in milliseconds for setTimer until the text disappears.

Basically, the function creates a dxDrawText for a specified time.

Thanks!

Don't expect people to make things for you. Also, that is really easy to do.

[patriot]

I can actually make it myself, but I don't know why that thing isn't working. Once I know what's the error in the following code, I will be able to make what I mentioned above.

  
function outPutFunc(string text) 
outputChatBox ( text ) 
end 
  

  
outPutFunc("Test") 
  

[Alen141]

you don't have commandhandler there

EDIT: or atleast trigger

[patriot]

I put "outPutFunc("Test")" under onClientRender.

use this ban example and try to fix it

function announceBan( theBan ) 
    if getElementType( source ) then --Check if a player banned the IP/Serial 
        outputChatBox( getPlayerName( source ) .. " banned " .. ( getBanSerial(theBan) or getBanIP(theBan) ) ) --Output to the chatbox saying the player has banned the IP/Serial 
    end 
end 
  
addEventHandler( "onBan", root, announceBan ) --Adds the event handler for 'onBan' and must be bound to root

function outPutFunc(string text) 

should be changed to

function outPutFunc(text)

All I wanted to know.

How do I make a bool parameter inside a function?

As far as I see when writing a LUA function there is no need to specifcy whether the parameter is a string ot int, but what when it comes to bool?

[Castillo]

function testFunction ( argument ) 
    outputChatBox ( "Argument value is '".. ( argument and "true" or "false" ) .."'" ) 
end 
  
testFunction ( true ) 
testFunction ( false ) 

Is that what you meant?

It's exactly the same.

local variable = 2; 
print( type( variable ) ); -- 'number' 
  
variable = "Something is wrong over there..."; 
print( type( variable ) ); -- 'string' 
  
variable = true; 
print( type( variable ) ); -- 'boolean' 

In Lua, you can change variable types by simply changing to a value of the type you want. In C++, for example, the type of the variables are "constant" - they're set at compile time and you can't change them at runtime ( well, actually you can but you might lose precision ).

Nevermind, got this already.

However, I tried to make the function that I wanted:

  
function dxText( text, timer ) 
    setTimer ( function() 
    dxDrawText ( .... ) 
    end, timer, 1 ) 
end 
  

  
addCommandHandler("showtext",function() 
dxGameText("Text test", 2000) 
end) 
  

But the text shows only after the specificed time and then disappears right away...

[Anderl]

You gotta draw the text right after calling the function and then create a timer to remove it, not create a timer to draw it first.

[Castillo]

dxDrawText requires the 'onClientRender' event in order to work.

[patriot]

Okay then, I will simply handle a dxDrawText with no text at all ("") and change it everytime by setting a varaiable which stores the text. Then I will create a timer to reset the text ("") and I guess problem sorted out.

Sorry for being so LUA newbie.

[Castillo]

You could always use GUI-labels.

[Anderl]

A more efficient way ( you won't notice it, but if you add more texts it may starting lagging ) is to create an "onClientRender" event and call it when you want to draw the text. You'll still need variables, though.
