Variable Speed

[BloodDrunk]

What performs faster; Boolean or Integer?
Or do they both change equally fast?

For those that don't understand:

Set Bool = true
Set Bool = false

Set Int = 1
Set Int = 0

is boolean slower than integer or?

bool is represented with 4 bytes, int is represented by 4 bytes(in warcraft 3, that is), so yeah, I think they are equal, or there is so small difference you will never observe it, no matter how long test you perform

^You know for sure it needs 4 bytes?

Edit: I mean boolean.^^

Use booleans for booleans. It makes your code more clear.

4 bytes in 1 boolean? lol

I can make 32 booleans in 4 bytes

@IcemanBo
nice 2k posts sharp

 

[edo494]

well, there are multiple claims about this, multiple members, and also http://wiki.thehelper.net/wc3/Jass_Primitive_Types#boolean claims that. + There is example of why isnt boolean 1 bit, but at very least 1 byte wide(64 returned from IsUnitType)

 

[IcemanBo]

1 bit would not work anways, but then I just believe TheHelper, as we anyway won't prove it. ^_°

Ty, Wietlol.

 

[Wietlol]

1 bit is indeed not enough to make a usable boolean but I didn't say that I can make 32 usable booleans but only 32 plain booleans.
In fact, I don't "make" 32 booleans because 4 bytes already are 32 booleans

 

[edo494]

you can in fact have 32 usable booleans in 4 bytes(std::vector<bool> anyone?) But according to multiple sources and claims, it is indeed 4 bytes, and it would make sense, because then the sizes of all variables are uniform to 4 bytes

Ook, asuming that they're equally fast (I like integer more, idk why).

Now another question:

Trigger - Turn off "name"
Trigger - Turn on "name"

Is this slower than setting a value to the variable?

 

[IcemanBo]

No it is not slower, because it is also variable actually. The variable be generated automatically.

 

[BloodDrunk]

Ok thanks people.

 

[IcemanBo]

Note if you use "This Trigger" in GUI, it's technically slower, because it's no variable but a function call.
