[HELP] Splitting number


steadyfi

Recommended Posts

Hello :)

How can I split a number into more numbers and store them in a table?

Example:

Number = 130

Split = 30,30,30,30,10

And then into a table: {30,30,30,30,10}

OR

Number = 54

Split = 30,24

And then into a table: {30,24}

The biggest number will always be 30, if reached then go form another.

Does anyone know ?

Thanks :D

Does not work with negative numbers
function split_number(number) 
    local values = { } 
  
    while (number > 0) do 
        values[#values + 1] = (number >= 30) and 30 or number 
        number = number - values[#values] 
    end 
  
    return values 
end 

Works with negative numbers:
function split_number(number) 
    local values = { } 
  
    while number ~= 0 do 
        if number > 0 then 
            values[#values + 1] = (number >= 30) and 30 or number 
        else 
            values[#values + 1] = (number <= -30) and -30 or number 
        end 
  
        number = number - values[#values] 
    end 
  
    return values 
end

end 

Ok, but how can I make it work with another table and number ?

I use it for a Weapon Magazine system.

I get the length of the initial table, then make as many values as that one has.

Example:

Mags: 30, 30, 30, 15, 0

# of values in Mags: 5

Number = getPedTotalAmmo (EX: 100)

Output: 30, 30, 30, 10, 0

How can I do this ? I want the player to keep the empty mags.

Done function for you. (i'm not good in math but it works)

local max = 30; 
function split ( n ) 
    if ( type ( n ) ~= "number" ) then 
        return false; 
    end 
     
    local x = ( n / max ) + 1; 
    local x = math.floor ( x + 0.5 ); 
     
    local numbers = { }; 
    local last = n; 
    for i=1, x do 
        local y = last / max; 
        if ( y > 1 ) then 
            table.insert ( numbers, max ); 
            last = last - max; 
        else 
            local z = n % max; 
            if ( z > 0 ) then 
                table.insert ( numbers, z ); 
            end 
        end 
    end 
     
    return numbers; 
end 

for _, v in pairs ( split ( 100 ) ) do 
    print ( v ); 
end 

It outputs

30

30

30

10

Doesn't work as intended.

I want to override the original table with the new values, but keeping the 0s

local max = 30; 
local mags = 5; 
function split ( n ) 
    if ( type ( n ) ~= "number" ) then 
        return false; 
    end 
     
    local numbers = { }; 
    local last = n; 
    for i=1, mags do 
        if ( last > 0 ) then 
            local y = last / max; 
            if ( y > 1 ) then 
                table.insert ( numbers, max ); 
                last = last - max; 
            else 
                local z = n % max; 
                table.insert ( numbers, z ); 
                last = last - z; 
            end 
            if ( last == 0 ) then 
                table.insert ( numbers, 0 ); 
            end 
        end 
    end 
     
    return numbers; 
end 
  
for _, v in pairs ( split ( 100 ) ) do 
    print ( v ); 
end 

Output:

Oops. Fixed.

  
function split ( n, max, mags ) 
    if ( type ( n ) ~= "number" ) then 
        return false; 
    end 
     
    local numbers = { }; 
    local last = n; 
    for i=1, mags do 
        if ( last > 0 ) then 
            local y = last / max; 
            if ( y > 1 ) then 
                table.insert ( numbers, max ); 
                last = last - max; 
            else 
                local z = n % max; 
                table.insert ( numbers, z ); 
                last = last - z; 
            end 
        else 
            table.insert ( numbers, 0 ); 
        end 
    end 
     
    return numbers; 
end 
  
for _, v in pairs ( split ( 100, 30, 5 ) ) do 
    print ( v ); 
end

There is a problem:

When I reload the Total Ammo goes down -30 but the clip is empty so Save and Load it and then I takes -30 again.

I was not having this problem.

Problem Representation:

Example Bullets: 180

Reload: -30 bullets

Reload isn't instant, there aren't bullets in weapon

The split get's triggered and then I load => -30 bullets

This is a scheme of how my system works:

Shoot Event Trigger > Get Ammo > Split > Save ElementData > Load ElementData > GiveBullets depending on ElementData
