[Voxel]

Basicly

pawn Код:

return 1;

means the script will see it as true and will execute it, if it returns false

pawn Код:

return 0;

it means the script will ignore it as far as I know. For example take OnPlayerUpdate, if it returns 0 the server wont update the player because the script is not executing it.
Theres probably someone that can explain this better, Good luck
