Ok so had a look and Yea i think this is my issue: put it to a 1 instead of -1
_ryanzombiesdisablebleeding = 1; // 1 to DISABLE player bleeding on hit, -1 to ENABLE player bleeding on hit.
_ryanzombiesstartinganim = 1; // Enable Spawning animation
_ryanzombieslimit = 30; // Player detection distance in meters
_ryanzombiesdisablemoaning = -1; // No idle sound
_ryanzombiesdisableaggressive = -1; // No aggressive sounds
_ryanzombiescivilianattacks = -1; // Attack civilians
_Ryanzombieslogicroam = 1; // Roam ***roaming can be heavy on cpu
_Ryanzombieslogicroamdemon = 1; // Demon Roam
