You can try this but I didn't test it.
PHP Code:
decl Float:flOrigin[3], Float:flAngles[3], Float:flFwdVec[3];
GetClientAbsOrigin(iClient, flOrigin);
GetClientEyeAngles(iClient, flAngles);
GetAngleVectors(flAngles, flFwdVec, NULL_VECTOR, NULL_VECTOR);
flOrigin[0] += flFwdVec[0] * 32;
flOrigin[1] += flFwdVec[1] * 32;
flOrigin[2] += flFwdVec[2] * 32;
