Joaquim também era bom fazeres esse tutorial em Portugues, tornava-se um bocadinho mais bem explicado para todos os tugas ;) Ja agora era porreiro se ensinasses a transformar um plugins a gravar os dados em NVault para MySQL, já ando a bastante tempo a tentar fazer isso mas não sei como. Abraço

This is an english forum. If you want to talk other languages, post in the Multilingual section.

You need to loop through all nVault entries and then send the keys / data to the database.

Hello, sorry for reviving.
I am totally new to coding and I have actually a couple of silly question..
In Part 1, in the

PHP Code:
changeColorLuminosity(anyColor[3],factor)
{
    
anyColor[0] = anyColor[0] + factor
    anyColor
[1] = anyColor[1] + factor
    anyColor
[2] = anyColor[2] + factor
    
    
if(anyColor[0] < 0)
    {
        
anyColor[0] = 0
    
}
    
    if(
anyColor[1] < 0)
    {
        
anyColor[1] = 0
    
}
        
    if(
anyColor[2] < 0)
    {
        
anyColor[2] = 0    
    
}

In the function, the factor. Should it be declared as a global variable before that?
and.. isn't
PHP Code:
changeColorLuminosity(anyColor[3]) 
is enough?
Thank you in advance. Sorry for asking a simple question..

Why? Because there is not one single universal truth which holds the meaning for everything.

"factor" is a formal parameter in that function, it does not have to be declared again. When you call that function you supply a value, which is called the actual parameter. This one may be declared. What I mean is:
PHP Code:
changeColorLuminosity(anyColor[3],factor//here you have formal params
{
    
anyColor[0] = anyColor[0] + factor
    anyColor
[1] = anyColor[1] + factor
    anyColor
[2] = anyColor[2] + factor
    
    
if(anyColor[0] < 0)
    {
        
anyColor[0] = 0
    
}
    
    if(
anyColor[1] < 0)
    {
        
anyColor[1] = 0
    
}
        
    if(
anyColor[2] < 0)
    {
        
anyColor[2] = 0    
    
}
}  

public 
some_function()
{
     new 
anyColor[3], factor 4
     changeColorLuminosity
(anyColorfactor// actual param, the variable "factor" is declared above. It can be global, if you need to use it in multiple functions. You could just do changeColorLuminosity(anyColor, 4), but it really depends on the plugin you are writting.

For the second question, it isn't enough for your function, because it has two formal params, so you need to provide two actual params.
I've tried to explain this as simple as I could.

Yes. If you do not pass the factor parameter and you function signature ìs `changeColorLuminosity(anyColor[3])`, you need to declare the `factor` as a global variable before the function declaration.


Example: (correct)


PHP Code:
new factor // everything ok

changeColorLuminosity(anyColor[3])
{
    
anyColor[0] = anyColor[0] + factor
    
....

Example: (incorrect)
PHP Code:
changeColorLuminosity(anyColor[3])
{
    
anyColor[0] = anyColor[0] + factor
    
....
}

new 
factor // variable not declared error 
However this is not true for functions declarations. This both cases are valid in AMXX pawn.

Example: (correct)
PHP Code:
func1(anyColor[3],factor)
{
    
anyColor[0] = anyColor[0] + factor
    
....
}

func2(anyColor[3],factor)
{
    
func1(anyColor,factor)
    ....

Example: (also correct)
PHP Code:
func2(anyColor[3])
{
    
func1(anyColor,factor)
    ....
}

func1(anyColor[3])
{
    
anyColor[0] = anyColor[0] + factor
    
....

Using a global variable is bad advice (because it prevents proper modularity). Leave it as a parameter of the function. What HamletEagle said is better.

If "JoKeR LauGh" wants to not provide the 'factor' parameter then a default value should be defined for that function.

I am not advising he to use global, I am just answering something which looked like a question about syntax.
He should use global when he needs the data be preserved across the whole plugin life.

If the variable `factor` does not need to hold such life cycle, he should not declare it as a global,
as he would just unnecessarily be increasing his code maintenance complexity unnecessarily.
Though, if he only need the factor to be alive on that function explicitly he can declare it locally as static.

If he want to know more search as https://www.google.com/search?q=why+globals+are+bad.
