amxx 1.9 crash
 
Hello, does anyone know why the code below crashes the sv? No log, clean crash.

PHP Code:
#include <amxmodx>
#include <amxmisc>

new Var1, Var2, Var3

public plugin_init()
{
    bind_pcvar_num(create_cvar("var1_test","1", .description = ""), Var1)
    bind_pcvar_num(create_cvar("var2_test", "1", .description = ""), Var2)
    bind_pcvar_num(create_cvar("var3_test", "1", .description = ""), Var3)
    set_task_ex(3.0, "Enabled", .flags = SetTask_Once)
    AutoExecConfig(.autoCreate = true, .name = "Test")
}

public Enabled()
{
    set_pcvar_num(Var1,0)    
    set_pcvar_num(Var2, 0)
    set_pcvar_num(Var3, 0)
}

You misunderstand the use of bind_pcvar_* natives.
They bind a cvar to a variable. Meaning that variable will contain the actual cvar's value in real time. This is NOT a cvar handle. You can't set a value from that.

To set a cvar with set_pcvar_num(), you still need to retrieve the handle from create_cvar() and using that value.
You can also use set_cvar_num(), it doesn't matter.

I had not really understood then, the correct use of the native bind_pcvar_ *, with the example quoted by me, how could I assign a value to pcvar? Or do I have to create just the pcvar with create_cvar and use it normally?

That's right, if you need to change the cvar's value, you have to store the return value from create_cvar and pass that to the set_pcvar_* functions as you normally would.

The bind_pcvar_* functions just set the passed in variable to the cvar's value and keep it automatically updated. That saves you from using get_pcvar_*/get_cvar_* every time you need to use the cvar's value.
