[Supremache]

Hello guys,
I have small problem i want help.
My question is: I was want to add no fall damage to bb mod and i have added some codes to plugin but nothing happening so where is the problem in those codes.

This is the defult

PHP Code:

public ham_TakeDamage(victim, inflictor, attacker, Float:damage, damagebits)
{
    if (!is_valid_ent(victim) || !g_isAlive[victim] || !is_user_connected(attacker))
        return HAM_IGNORED
        
    if(g_boolCanBuild || g_boolRoundEnded || g_boolPrepTime)
        return HAM_SUPERCEDE;

    if (victim == attacker)
        return HAM_SUPERCEDE;
        
    if (g_iSupercut)
    {
        damage*=99.0
    }
        
    SetHamParamFloat(4, damage)
    return HAM_HANDLED
} 


What i did:

PHP Code:

public ham_TakeDamage(victim, inflictor, attacker, Float:damage, damagebits)
{
    if (!is_valid_ent(victim) || !g_isAlive[victim] || !is_user_connected(attacker))
        return HAM_IGNORED
        
    if(g_boolCanBuild || g_boolRoundEnded || g_boolPrepTime)
        return HAM_SUPERCEDE;

    if (victim == attacker)
        return HAM_SUPERCEDE;
        
    if(damagebits & DMG_FALL)
        return HAM_SUPERCEDE;
        
    if (g_iSupercut)
    {
        damage*=99.0
    }
        
    SetHamParamFloat(4, damage)
    return HAM_HANDLED
