Why are all of those complications necessary? This works just fine:
PHP Code:
#include <amxmodx>
#include <hamsandwich>
#define DMG_FALL (1<<5)
public plugin_init()
{
register_plugin("No Fall Damage", "1.0", "OciXCrom")
RegisterHam(Ham_TakeDamage, "player", "OnTakeDamagePre", 0)
}
public OnTakeDamagePre(iVictim, iInflictor, iAttacker, Float:fDamage, iBits)
return iBits & DMG_FALL ? HAM_SUPERCEDE : HAM_IGNORED
