Hello guys! I have 2 questions (I know about 1 question per topic)
1) If i holding a knife, then typing "changeknife 1" in console, viewmodel isn't changing immediately. I need to change to any other weapon and then change back to knife. Is there any way to fix this?
2) Which weapon models can be changed via "entity_set_string(id, EV_SZ_viewmodel, modelname)"?
Here is the script i using:

PHP Code:

#include < amxmodx >
#include < engine >

new const models[][] = {
    "models/v_knife.mdl",
    "models/p_knife.mdl",
    "models/v_knife_r.mdl"
}

enum _:udata {
    knife
}

new UserData[33][udata]

public plugin_precache()
{
    for(new i; i < sizeof(models); i++)
        precache_model(models[i])
}

public plugin_init() {
    register_plugin ("knife changer", "test", "kww (yes)")
    
    register_event ("CurWeapon", "event_curweapon", "be", "1=1")
    register_clcmd ("changeknife", "xknife_handler")
}

public client_putinserver ( id ) {
    UserData[id][knife] = 0
}

public xknife_handler(id) {
    new x_arg[16]
    read_argv(1, x_arg, charsmax(x_arg))
    
    switch(x_arg[0]) {
        case EOS: client_print(id, print_console, "* Usage: changeknife <1|0> (now %i)", UserData[id][knife])
        case '0': UserData[id][knife] = 0
        case '1': UserData[id][knife] = 1
    }
    client_print(id, print_console, "%i", )
    return PLUGIN_HANDLED
}

public event_curweapon(id) {
    new wpn = read_data(2)
    if (wpn == CSW_KNIFE) {
        switch (UserData[id][knife]) {
            case 0:
            {
                entity_set_string(id, EV_SZ_viewmodel, models[0])
                entity_set_string(id, EV_SZ_weaponmodel, models[1])
            }
            case 1:
            {
                entity_set_string(id, EV_SZ_viewmodel, models[2])
            }
        }
    }
    
    return PLUGIN_CONTINUE
}
