a course of 60 seconds.
I'm trying to raise time.
Values after 127 seconds go to - minus.
Code and warnings below, which is the idea?

Code:
code
; d0
getlocal_0
; 30
pushscope
; 5d b8 9f 01
findpropstrict Qname(PackageNamespace("net.shared.cheats"),"isCheatActivated")
; 60 31
getlex Qname(PackageNamespace("net.model.cheat"),"CheatFlagName")
; 66 f5 87 01
getproperty Qname(PackageNamespace(""),"QUICK")
; 46 b8 9f 01 01
callproperty Qname(PackageNamespace("net.shared.cheats"),"isCheatActivated") 1
; 12 0e 00 00
iffalse ofs0023
; 5e dc 88 01
findproperty Qname(PrivateNamespace(null,"157"),"MAX_GAMEPLAY_TIME")
; 24 0b
pushbyte 11
; 61 dc 88 01
setproperty Qname(PrivateNamespace(null,"157"),"MAX_GAMEPLAY_TIME")
; 10 0a 00 00
jump ofs002d
; 5e dc 88 01
ofs0023:findproperty Qname(PrivateNamespace(null,"157"),"MAX_GAMEPLAY_TIME")
; 24 3c
pushbyte 60
; 61 dc 88 01
setproperty Qname(PrivateNamespace(null,"157"),"MAX_GAMEPLAY_TIME")
; 5e dd 88 01
ofs002d:findproperty Qname(PrivateNamespace(null,"157"),"START_TIMEOUT_SOUND_TIME")
; 60 dc 88 01
getlex Qname(PrivateNamespace(null,"157"),"MAX_GAMEPLAY_TIME")
; 60 db 88 01
getlex Qname(PrivateNamespace(null,"157"),"TIMEOUT_SOUND_DURATION")
; a1
subtract
; 61 dd 88 01
setproperty Qname(PrivateNamespace(null,"157"),"START_TIMEOUT_SOUND_TIME")
; 47
returnvoid



The exchange codes used:

Code:
24 0b ?? ?? ?? 01 10 0a 00 00 5e ?? ?? 01 24 3c
24 ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? 25 fe 01 //and 48


Code:
24 0b ?? ?? ?? 01 10 0a 00 00 5e ?? ?? 01 24 3c
24 ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? 24 7f


Code:
24 0b ?? ?? ?? 01 10 0a 00 00 5e ?? ?? 01 24 3c
24 ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? 2d eb 06 //and 48



warnings:

Quote:
Byte value expected (-128 to 127).
Use pushshort or pushint to push larger values on line 18.


- how can I assign a 180-second value without entering a minus?

thanks in advance for answers

you'd have to change the type, if or how you can do that in flash ¯\_(ツ)_/¯

Use pushshort or pushint


I applied the recommendations in the example.
But, again, it beats values between minus or plus million.
I couldn't raise the seconds to more than 127.
I'm new to Flash Decompiler. Is an example available?

Do as it says: use pushshort or pushint to push larger values.

Many instructions use a variable-length encoded 30-bit unsigned integer value (u30). This operand includes the next byte in the value if the highest bit of the current byte is set.
Code:
raw bytes:
C0 84 3D    - only 3 bytes, but highest bit of last byte isn't set, so value ends here

binary notation:
11000000 10000100 00111101

reverse order (little endian):
00111101 10000100 11000000

remove highest bit:
0111101 0000100 1000000

concatenate bits:
011110100001001000000

real value:
1,000,000 (decimal)

pushshort takes a u30 and pushes it on the stack.
pushint pushes an int from the constant pool. It still uses a u30 to index into the pool.

It's going to take up more bytes than the original instruction, so optimize or remove code to make room for it. e.g. optimize the setproperty outside the if/else statement.

If and else the opinion is good. but I can't give the value out of "if and else".
still worth 127 Max. more raise minus value.
The nice thing is: I just started the language 'C #' and
Surprised to see the same encodings. Smile



In this context, "u30" makes a negative value assignment.
So: "B4 01" gives the error as minus in the game.
I may still need a sample.


Code:
[MessageHandler]
      public function handleIncreaseGameplayTime(param1:IncreaseGameplayTime) : void
      {
         this.increaseGameplayTime(param1.seconds);
      }
     
      private function setMaxGameplayTime() : void
      {
         if(isCheatActivated(CheatFlagName.QUICK))
         {
            MAX_GAMEPLAY_TIME = 11;
         }
         else
         {
            MAX_GAMEPLAY_TIME = 60;
         }
         START_TIMEOUT_SOUND_TIME = MAX_GAMEPLAY_TIME - TIMEOUT_SOUND_DURATION;
      }

As ParkourPenguin said, manipulate if/else to make room,
Code:

; 46 b8 9f 01 01
callproperty Qname(PackageNamespace("net.shared.cheats"),"isCheatActivated") 1
; 12 0e 00 00     ======> 29 25 b4 01   ;; popstack / pushInt 180   ;; also remove test
iffalse ofs0023
; 5e dc 88 01
findproperty Qname(PrivateNamespace(null,"157"),"MAX_GAMEPLAY_TIME")
; 24 0b           ======> 2b 02       ;; swapstack / nop ;; fix stack order
pushbyte 11
; 61 dc 88 01
setproperty Qname(PrivateNamespace(null,"157"),"MAX_GAMEPLAY_TIME")

ie
Code:

scan: 12 0e 00 00 5e ?? ?? ?? 24 0b
swap: 29 25 b4 01 ?? ?? ?? ?? 2b 02

let's pray it work~

It worked great. Very Happy
Now I have to spend some more time for "C #".
Thanks for this excellent coding.
+1 always the masters.
Thanks again.
