If it's used more than once in the script, the data only appears in memory once. If you use the define, the memory is allocated for each time it's referenced.

It's optimized for memory consumption not for speed.
The macros are replaced at compile-time so even if the same data is held multiple times, it resides in the same segment thus improving RT efficiency.

I do believe that in terms of HL scripting optimizations should be done for speed rather than memory consumption.

AFAIK it's the same speed, just less overhead. I don't know where you got that it's slower, but I'm reasonably sure that it's not (although I can't back it).

The define is almost definitely not slower, but I imagine that they're the same speed.

Then again, there's one major advantage: if someone is stupid and tries to change the define to another type (say it's 20.0 and they change it to 15), the compiler will yell at them for having a tag mismatch there. It's even better for an array because it just won't compile at all. Of course you'd get errors later on even if you didn't use this (unless multiple tags is allowed for a section), but the error right up front helps diagnosis.

thanks, I'll read the TUT when I get some time

hawk fix ur code, its suppose to be halflife_time()+20.0 or somethin or else its gonna be called every frame

I already said I'd add that in but the stupid editor is broken. I'm too lazy to change my settings.

[purple_pixie]

It's not a lot of effort ...

And it makes editing a lot easier.

I can happily edit my posts now, and the code still comes out fine.

EDIT: Is there a notice anywhere that says "btw, if you want to be able to edit posts with tags in them, you have to change your settings to the flat text editor" or are we all meant to work that out?

Aren't we getting a bit off-topic ?

How does engine know when it is the time to call Think on specified entity? It must check time sometimes, but how often?

I escaped usage of set_task with "b" flag by counting server frames. When frames counter reach certain value then time is checked, so I can determine how many frames must pass until certain time will pass (if average server fps will not change much).

example code:

PHP Code:

#include <amxmodx>
#include <fakemeta>

#define UPDATE_TIME 1.0

new g_check_frame = 100
new g_f2_exec_frame = 100
new Float:g_f2_interval = 0.3

public plugin_init(){
    register_plugin( "test", "1.0", "Sylwester")
    register_forward(FM_StartFrame, "fwd_StartFrame")
}

public fwd_StartFrame(){
    static Float:current_time
    static Float:last_time
    static frames_counter
    static frames_counter2
    
    frames_counter++
    if(frames_counter > g_check_frame){
        current_time = get_gametime()
        g_check_frame = floatround(g_check_frame*UPDATE_TIME/(current_time-last_time))+1
        g_f2_exec_frame = floatround(g_check_frame/UPDATE_TIME * g_f2_interval)
        last_time = current_time
        frames_counter = 1
        func1()
    }

    frames_counter2++
    if(frames_counter2 > g_f2_exec_frame){
        frames_counter2 = 1
        func2()
    }
}

func1(){
//func1 will be executed every about 1 second
}

func2(){
//func2 will be executed every about 0.3 second
} 


This method is not 100% accurate. Time between two function calls may differ little from desired time, but in some cases you don't need it to be so accurate.

Which method takes more CPU power? This one or method with setting next think on entity?

btw I copied first post to txt file...

[Hawk552]

Totally useless. I used this in my "Game Status HUD Display" plugin, but it's terrible for measuring time intervals. Please, I urge no one to use this unless their task is extremely insensitive to time.

server frames fluctuates like crazy
