Hello there, please help on table.sort i do googling but i can't find the answer for my needed to my script here is the script below
i want to list the value of kn(which is describe below) then sort it from ascending to descending the result my vary because Value always change
| Code: |
al = getAddressList()
getMr = al.getMemoryRecordByDescription
K = {(getMr('kn1')),(getMr('kn2')),(getMr('kn3')),(getMr('kn4')),(getMr('kn5')),(getMr('kn6')),(getMr('kn7')),(getMr('kn8')),(getMr('kn9'))}
for i = 1, 9 do print(K[i].Value) end
result when printed unsorted:
5439554
4849744
4325453
4390989
5111887
2752569
2752576

what i want is result should begin froma smallest to largest
refer to DB answer to this post https://forum.cheatengine.org/viewtopic.php?p=5777131&sid=f69ceb63c0038fb042258dbd181da47e i did change
| Code: |
K = {
{(getMr('kn1'))},
{(getMr('kn2'))},
{(getMr('kn3'))},
{(getMr('kn4'))},
{(getMr('kn5'))},
{(getMr('kn6'))},
{(getMr('kn7'))},
{(getMr('kn8'))},
{(getMr('kn9'))}
}
table.sort(K, function(a,b)
if a.Value[5439554]~=b[5439554] then
return a[5439554]<b[5439554]
else
return a[2752569 ]<b[2752569 ]
end
end)
for i=1,K do
print(K[i][2752569 ],K[i][5439554])
end
|
it gives me an error Error:[string "al = getAddressList()
..."]:4: attempt to index a nil value (field '?')
Script Error
thanks in advance

In your case the code could be:
Ignores list comments.
It just sorts the values.
For example 1;
| Code: | al = getAddressList()
getMr = al.getMemoryRecordByDescription
K = {(getMr('kn1')),(getMr('kn2')),(getMr('kn3')),(getMr('kn4')),(getMr('kn5')),(getMr('kn6')),(getMr('kn7')),(getMr('kn8')),(getMr('kn9'))}
function SorTbl(tbl)
T={}
al = getAddressList()
getMr = al.getMemoryRecordByDescription
for i=1, #tbl do
desVal=tbl[i].Value
--print(desVal)
T[i]=desVal
end
if T then
table.sort(T)
end
return T
end
K1=SorTbl(K)
minVal=K1[1]
maxVal=K1[#K1]
print("Min Value: " .. minVal .. "\nMax Value: " .. maxVal)
--for i = 1, 9 do print(K1[i]) end |
For example 2;
| Code: | al = getAddressList()
getMr = al.getMemoryRecordByDescription
K = {(getMr('kn1').Value),(getMr('kn2').Value),(getMr('kn3').Value),(getMr('kn4').Value),(getMr('kn5').Value),(getMr('kn6').Value),(getMr('kn7').Value),(getMr('kn8').Value),(getMr('kn9').Value)}
table.sort(K)
minVal=K[1]
maxVal=K[#K]
print("Min Value: " .. minVal .. "\nMax Value: " .. maxVal)
--for i = 1, 9 do print(K[i]) end |
| Code: | al = getAddressList()
getMr = al.getMemoryRecordByDescription
K = {{"kn1",(getMr('kn1').Value)},
{"kn2",(getMr('kn2').Value)},
{"kn3",(getMr('kn3').Value)},
{"kn4",(getMr('kn4').Value)},
{"kn5",(getMr('kn5').Value)},
{"kn6",(getMr('kn6').Value)},
{"kn7",(getMr('kn7').Value)},
{"kn8",(getMr('kn8').Value)},
{"kn9",(getMr('kn9').Value)}}
table.sort(K, function(a,b) return a[2]<b[2] end)
for i = 1, 9 do print(K[i][1],K[i][2]) end |
With list descriptions:
| Code: | al = getAddressList()
getMr = al.getMemoryRecordByDescription
K = {{"kn1",(getMr('kn1').Value)},
{"kn2",(getMr('kn2').Value)},
{"kn3",(getMr('kn3').Value)},
{"kn4",(getMr('kn4').Value)},
{"kn5",(getMr('kn5').Value)},
{"kn6",(getMr('kn6').Value)},
{"kn7",(getMr('kn7').Value)},
{"kn8",(getMr('kn8').Value)},
{"kn9",(getMr('kn9').Value)}}
table.sort(K, function(a,b) return a[2]<b[2] end)
for i = 1, 9 do print(K[i][1],K[i][2]) end
print("Value Max: " .. K[9][1],K[9][2])
function DescValue(tbl,desc)
res=""
for i,k in pairs(tbl) do
if k[1]==desc then
--print(1,k[1])
res=k[2]
end
end
return res
end
print("Value Desc kn4: " .. DescValue(K,"kn4")) |

1. sort in 'string' type is different from sort in 'number' type, for instant string'123' < string '99' while number 123 > number 99, and memory record .Value is of string type ; and it can be '??' (unreadable etc);
To sort numberically, may use tonumber function and should handle unreadable.
eg. this sort ascending and move unreadable to last (replace by a larger number); table use last K = {memroy-records...} and assume the records exist (if no typo etc)
| Code: |
local unreadable = math.huge -- or math.maxinteger (and -math.huge / math.mininteger for decending sort)
table.sort(K, function(a, b)
local va = tonumber(a.Value) or unreadbable
local vb = tonumber(b.Value) or unreadbable
return va < vb
end)
|
in general, a,b should convert parallelly before the comparison.
2. the link you refer to, later code by DB, is a kind of multi level sorting, do you really need it?
3. what is the actual effect of the sorting you want? eg. re-arrange your memory record or just printing?
