 Posted: Sat Jan 19, 2013 6:46 pm Post subject: Adding Slow Motion & Getting Error: Attempt to Call Glob |
 |
|
Hey,
What I'm trying to do is add 'slow motion' (referred to as Quicksilver) to a game, but it must drain energy (called Devil Trigger, DT in game) while active, and it must be activated like a toggle on a button press when energy is at a certain value.
Previously what I get with the script is, the game isn't being slowed, and after the Lua Engine announces "If statement working", then there's a few seconds of nothing happening, then it announces "If DT is 0,0 check made with some random value in the negatives, then "QS2 called", while no values in game were changed at all.
The values are being read correctly, and parts of this have worked before especially the ones that are having problems now.
Now when I relaunched the game & CE I get (changes to the script is just updated addresses):
Error:[string "--Quicksilver Style for Devil May Cry 4 DX9..."]:22: attempt to call global 'Quicksilver' (a nil value)
I don't understand what's going on for me to get this error all of a sudden.
I'm also not sure on how to express pointers, I'm just updating the address pointed to. The first two lines are an attempt and the output is "testpointer is [blank]"
The game's process name is DevilMayCry4_DX9.exe
The pointer is 00e558d0 with an offset of 34
Here's what I have now; sorry if it's a bit long.
| Code: |
testpointer = '["DevilMayCry4_DX9.exe"+00E558D0]+34'
print ("testpointer is", readFloat(testpointer))
Quicksilver ()
---------Write Function Here--------------
---------"Game" Function--------------
function Quicksilver () --Quicksilver Check and Enabler
print ("Quicksilver function called");
DTdrainTimer = createTimer(window, true); --"Devil Trigger Drain"
timer_setInterval(DTdrainTimer, 100); --ticks per 100 milliseconds, quantity statement @ line 47
--'[[[["DevilMayCry4_DX9.exe"+00A552CC]+1f24]+9c]+2e4]+164';--Devil Trigger pointer (entire)
local DTad = '0x19262AA4'; --Devil Trigger Address; will change per reload
--local DTad = '[[[["DevilMayCry4_DX9.exe"+00A552CC]+1f24]+9c]+2e4]+164';--Devil Trigger pointer
DT = readFloat(DTad); --Devil Trigger value
local EmWR = '0x17AD85A0'; --Enemy Work Rate; to adjust for different executables, just change this
local SetWR = '0x17AD85A4'; --Set Work Rate
print ("DT is", readFloat(DTad)) --debugging
print ("DTad is", DTad)
print ("EmWr is ", readFloat(EmWR))
print ("SetWr is", readFloat(SetWR))
if DT >= 3000.0 then --required to start
print ("If statement working");
writeFloat(EmWr, .2); --Enemy Work Rate
writeFloat(SetWr, .1); --Set Work Rate
timer_onTimer(DTdrainTimer, DTdrain);
end; --end if statements
end; --end function Quicksilver
function DTdrain () --Devil Trigger Drain; Timer object is created in Quicksilver ()
--if DT ~= nil then --lazy if fix
DT = DT - 100.0; --Quantity drained, interval statement @ line 24
writeFloat(DTad, DT);
if DT <= 0.0 then --when DT ticks to or below 0,
print ("If DT is 0.0 check made", DT)
writeFloat (DTad, 0.0); --in case DT hits a negative number
Quicksilver2(); -- Quicksilver state ends
end; --end of if statements
--end; --lazy if fix
end ; --end function DTdrain
function Quicksilver2 ()--Intended for disabling
print ("QS2 called")
object_destroy(DTdrainTimer) --destroys DT drain timer
writeFloat(EmWr, 1.0); --restores Work Rates to normal
writeFloat(SetWr, 1.0);
end; --end function Quicksilver 2

Because LUA interpreter goes through line-by-line. Functions must be initialized, before you launch them. Move "Quicksilver()" to the bottom.
| Quote: | | The pointer is 00e558d0 with an offset of 34 |
So it would be:
print ("testpointer is", readFloat('[DevilMayCry4_DX9.exe+00E558D0]+34') )
or
print ("testpointer is", readFloat('[00E558D0]+34') )
?
Edit:
Maybe something like this:
| Code: | -- pointers and addresses
-- to adjust for different executables, just change this
DTad = "[[[[DevilMayCry4_DX9.exe+00A552CC]+1f24]+9c]+2e4]+164" --Devil Trigger pointer
EmWR = "0x17AD85A0" -- Enemy Work Rate
SetWR = "0x17AD85A4" -- Set Work Rate
drainValue = 100.0
WorkRate = 0.1
EnemyWorkRate = 0.2
debugMode = true
function debugMessage(s)
if debugMode then print(s) end
end
---------Write Function Here--------------
---------"Game" Function--------------
function Quicksilver () --Quicksilver Check and Enabler
debugMessage ("Quicksilver function called")
DT = readFloat(DTad) --Devil Trigger value
debugMessage("DT is "..readFloat(DTad)) --debugging
debugMessage("EmWr is "..readFloat(EmWR))
debugMessage("SetWr is "..readFloat(SetWR))
if DT >= 3000.0 then --required to start
debugMessage("Quicksilver now works")
writeFloat(SetWr, WorkRate)
writeFloat(EmWr , EnemyWorkRate)
timer_setEnabled(DTdrainTimer,true)
end
end --end function Quicksilver
function DTdrain() --Devil Trigger Drain Timer object is created in Quicksilver ()
DT = DT - drainValue
writeFloat(DTad, (DT>0) and DT or 0.0 )
if DT <= 0.0 then --check if depleted
timer_setEnabled(DTdrainTimer,false) -- disable timer
writeFloat(EmWr, 1.0) --restores Work Rates to normal
writeFloat(SetWr, 1.0)
debugMessage("DT is 0.0 now ")
end
end
--prepare timer object
if DTdrainTimer~=nil then object_destroy(DTdrainTimer);DTdrainTimer=nil;end
DTdrainTimer = createTimer(window, false) --"Devil Trigger Drain"
timer_setInterval(DTdrainTimer, 100) --tick per 100 milliseconds
timer_onTimer(DTdrainTimer, DTdrain)
--launch it
Quicksilver()

Thanks for the reply; everything's working (after a few other adjustments) and that code does look nice especially with the debugging function and keeping values organized, but Quicksilver2() existed so the effect can be cancelled on a toggle.
| Quote: | | writeFloat(DTad, (DT>0) and DT or 0.0 ) |
And can you explain that part? The help file says writeFloat(address, value), but that's an expression.[/quote]

OK, here
| Code: | function QuicksilverDisable() --Intended for disabling
debugMessage("Quicksilver disabled")
timer_setEnabled(DTdrainTimer,false)
writeFloat(EmWr, 1.0); --restores Work Rates to normal
writeFloat(SetWr, 1.0);
end |
| Quote: | writeFloat(DTad, (DT>0) and DT or 0.0 )
(...)
And can you explain that part? |
"The conjunction operator (and) returns its first argument if this value is false or nil; otherwise, and returns its second argument. The disjunction operator (or) returns its first argument if this value is different from nil and false; otherwise, or returns its second argument. Both and and or use short-cut evaluation, that is, the second operand is evaluated only if necessary"
Two cases:
1) DT is bigger than 0
It will be:
true and DT or 0.0
And this is:
DT or 0.0
And this is:
DT
2) DT is less than or equal to 0
It will be:
false and DT or 0.0
And this is:
false or 0.0
And this is:
0.0
It's similar to c++ condition operator ?:
int A = DT>0 ? DT : 0;
