Are PlayerInfo[playerid][pPosX], PlayerInfo[playerid][pPosY] and PlayerInfo[playerid][pPosZ] defined as floats?

Like:

pawn Код:

enum pInfo
{
  Float:pPosX,
  Float:pPosY,
  Float:pPosZ
};

You probably forgot the Float: tag.

EDIT: Here's another reason for the warning:
You're using dUserSetINT which is only for INTEGERS. Use dUserSetFLOAT for FLOAT numbers.
