You don't need a trainer for moods.
On the neighborhood screen, open the cheat console (Ctrl+Shift+C)
Now, type in boolprop TestingCheatsEnabled 1
Now go into any lot with a family (or make a new one) and Shift+Left Click items to get new options for them.
As for the moods, you can now simply click and drag the mood bars until they are full! This also works for the job screen (skills), personality, interests, and relationships!
Now with the Shift Click thing, hold shift and click the mailbox on your lot, choose Household, then choose Static Motives. This freezes motives where they are, though they can still be changed by certain things.
This also unlocks a Debug Mode for Create a Sim (possibly create a pet too, but I have not tried that yet)
On the Create a Sim screen, simply press Shift+N to enter debug mode, and now you can use new clothes and skin types you couldnt use before! (like the alien skintype gets unlocked, and work uniforms too)
Press Shift+M to exit this mode
