[Trigger] Which is more efficient ?

[defskull]

Straight to the point, which is more efficient ?

TRIGGER 1:

• Actions
  • Set Integer = (Level of Acid Bomb for (Triggering unit))
  • Set Damage = (Damage x (Real(AbilityLevel)))

TRIGGER 2:

• Actions
  • Set Real = (Real((Level of Acid Bomb for (Triggering unit))))
  • Set Damage = (Damage x Real)

Since both trigger consisting of "conversion", which is more efficient or both of them performs at a same degree ?

Basically:
TRIGGER 1 = I2R
TRIGGER 2 = R2I
Damage = Real

you really should focus on other things to improve performance like choosing the right special effects, using indexing over hashtables and SetUnitX/Y over "Move Unit instantly", maybe a filter function for unit group enumerations (well....at this point you could move to JASS anyway)

slow car is slow, no matter which color you paint it

All I know is conversion will surely cause trigger to run slower. (But very little)
Integer Variable In c++ will reduce using of memory.

Anyway Warcraft III store all variable in the same size of memory. (Real and integer are using the same size of memory)
From my knowledge, in Warcraft III, they are the same.

Are you on the right thread ?

Are you on the right thread ?

Dark Gandalf wants to say that what you're asking is redundant and if you're really going to care so much for efficiency, why do you use GUI?

 

[defskull]

If you like Porsche, why buy a Ferrari ?
It's the same thing, and it's personal opinion to choose JASS over GUI
I, myself, acknowledged that JASS > GUI, but you don't have to force GUIer to change over to JASS
What I'm asking now is current situation (don't go outside the box... like DSG sometimes saying about Starcraft II but we're actually on Warcraft III forum area)

 

[Garfield1337]

The difference in efficiency is too small (if it exists) to be noticed.

 

[defskull]

Agreed on that
But when it comes to "Spell Section"...
Everything needs to be perfect, therefore, I want to know which is the best and most efficient of all function/action/etc (IN GUI!)

 

[Bribe]

They operate at exactly the same speed.

However, if you plan to reference the level of the unit several times (as an integer), save it as an integer variable and reference it as a real only when necessary.

In WC3...
A real is a single precision float.
An integer is a 32bit siged integer type.

Due to the differences in how the data is stored and manipulated...
Float opperations are often slower than equivelent integer opperations.
Changing between the 2 types takes time.
Converting to integer loses range while converting to float looses precision.
Instructions may exist to allow integer interaction with floats directily (no need to convert).

In JASS (WC3)
All integers will automatically convert to reals when required (implied conversion)
All reals must be converted to integer through a native call (which if it executes a separate function will be stupdily slow).
GUI uses special Integer to Real converter function which is nothing but bloat (slower).

Do be aware that conversions are need to be done for every field that takes a real if passed an integer which may mean storing a value as a real yields a speed up for that situation.
