[Terraria] Calculating Timers...
I managed to get some things out of Terraria via Steam Version. Not supporting the cracked/non-steam at the moment. So the timer was found for buffs, however, I am unable to translate it to a double/float in order to compensate the milliseconds and seconds apart from each other.
The timer is stored in a 4 Byte Value on an address, or I should say the timer itself is 4 Bytes Long.
I did manage to find out that the multiplier is 59. So, in order to get 30 minutes of a buff, you must do the following:
59 * 60 * 30 = 30 Minutes of Buff
Here is the table so far:
Anyone know a way to translate the timer value to a more proper easy method in seconds? Rather than this strange formula?

Add new custom type:
| Code: | alloc(ConvertRoutine,1024)
alloc(ConvertBackRoutine,1024)
alloc(TypeName,256)
alloc(ByteSize,4)
alloc(value59,4)
value59:
dd (float)59
TypeName:
db 'TerrariaTimer',0
ByteSize:
dd 4
ConvertRoutine:
push ebp
mov ebp,esp
mov eax,[ebp+8]
mov eax,[eax]
cvtsi2ss xmm0,eax
divss xmm0,[value59]
cvtss2si eax,xmm0
pop ebp
ret 4
ConvertBackRoutine:
push ebp
mov ebp,esp
push eax
push ebx
mov ebx,[ebp+c]
cvtsi2ss xmm0,[ebp+8]
mulss xmm0,[value59]
cvtss2si eax,xmm0
mov [ebx],eax
pop ebx
pop eax
pop ebp
ret 8 |
all values will be seconds (integer - 4byte)
Or if you prefer seconds as float, use this:
| Code: | alloc(ConvertRoutine,1024)
alloc(ConvertBackRoutine,1024)
alloc(TypeName,256)
alloc(ByteSize,4)
alloc(UsesFloat,4)
alloc(value59,4)
value59:
dd (float)59
TypeName:
db 'TerrariaTimer_float',0
ByteSize:
dd 4
UsesFloat:
dd 1
ConvertRoutine:
push ebp
mov ebp,esp
mov eax,[ebp+8]
mov eax,[eax]
push eax
cvtsi2ss xmm0,eax
divss xmm0,[value59]
movss [esp],xmm0
pop eax
pop ebp
ret 4
ConvertBackRoutine:
push ebp
mov ebp,esp
push eax
push ebx
mov ebx,[ebp+c]
movss xmm0,[ebp+8]
mulss xmm0,[value59]
cvttss2si eax,xmm0
mov [ebx],eax
pop ebx
pop eax
pop ebp
ret 8

I thank you for this code, but I is there a place I can learn something like this? Next time I need to do this, I probably won't know how to do that. So, if you can link me to some tutorial that teaches you these scripts that would be great.
Thanks

Terraria is written in C# and is not protected. You can use tools like ilSpy to decompile it and check out the code. (The developer encourages it as well for modders.)
| Code: |
case 425:
this.mana = 40;
this.channel = true;
this.damage = 0;
this.useStyle = 1;
this.name = "Fairy Bell";
this.shoot = 72;
this.width = 24;
this.height = 24;
this.useSound = 25;
this.useAnimation = 20;
this.useTime = 20;
this.rare = 5;
this.noMelee = true;
this.toolTip = "Summons a magical fairy";
this.value = (this.value = 250000);
this.buffType = 27;
this.buffTime = 18000;
break;
|
For example, this is the Fairy Bell item.
The duration is 18000.
Which is actually 300 seconds. (18000/60)
