Let's say I have a group of 50 entites of 6 classtypes.
I want to perform an action on particular entity after aiming at it.

Is it more efficient to check if the entities index falls within a certain number

PHP Code:

if(50 <= entity <= 100)//hypothetical index values
{
do stuff;
} 


or

is it more efficient to check if they are of the desired class

PHP Code:

GetEntityClassname(entity,string,length);
if (string = desiredclass)
{
do someting;
}

It is way more efficient to the computer to compare numbers rather then compare strings.

I am not quite sure what you are trying to do.

String comparisons are "fast" but there is a faster solution. In theory, SourceMod could cache the internal function "vtables" of each entity type. Then we could have something like...

IsEntityType(ent, "type") and it would be able to compute it in O(k) time for you.

Maybe something to file a feature request for. There's definitely a solution to optimizing your problem, and it's important for high-profile callbacks.
